Joint pain during childhood, particularly in the large joints of the lower extremities, is common. Degenerative joint disease is progressive; approximately 50% of individuals with COMP-PSACH eventually require hip replacement surgery., The diagnosis of COMP-PSACH can be made on the basis of clinical findings and radiographic features. Identification of a heterozygous pathogenic variant in COMP on molecular genetic testing establishes the diagnosis if clinical features are inconclusive., Treatment of manifestations: Analgesics for joint pain; encourage physical activities that do not cause excessive wear and/or damage to the joints; osteotomy for lower limb malalignment; rarely, surgery for scoliosis; C1-C2 fixation for symptoms and radiographic evidence of cervical spine instability; attention to and social support for psychosocial issues related to short stature for affected individuals and their families.

Testing of asymptomatic adults at risk for HDL2 is possible once a heterozygous expansion of a CTG repeat in JPH3 has been identified in an affected family member. Testing for the JPH3 CTG repeat expansion in the absence of definite manifestations of the disease is predictive testing. Prudence suggests following the same genetic testing guidelines used for HD, including counseling prior to testing, a confidant to serve as a social support, and availability of counseling following the disclosure of genetic results.

Ten responsible genes have been identified for spinocerebellar ataxia types SCA1, SCA2, SCA3, SCA6, SCA7, SCA8, SCA10, SCA12 and SCA17, and dentatorubral pallidoluysian atrophy (DRPLA). The mutation is caused by an expansion of a CAG, CTG or ATTCT repeat sequence of these genes. Six additional loci, SCA4, SCA5, SCA11, SCA13, SCA14 and SCA16 have also been mapped. The growing heterogeneity of the autosomal dominant forms of these diseases shows that the genetic aetiologies of at least 20% of ADCA have yet to be elucidated. We ascertained and clinically characterized a four-generation Chinese pedigree segregating an autosomal dominant phenotype for cerebellar ataxia. Direct mutation analysis, linkage analysis for all known SCA loci and a genome-wide linkage study were performed.

This large amount of implicated genes accounts for heterogeneous clinical presentations, making genotype-phenotype correlations a major challenge in the field. While polyglutamine ataxias, linked to CAG repeat expansions in genes such as ATXN1, ATXN2, ATXN3, ATXN7, CACNA1A and TBP, have been extensively characterized in large cohorts, there is a need for comprehensive assessment of frequency and phenotype of more 'conventional' ataxias. After exclusion of CAG/polyglutamine expansions in spinocerebellar ataxia genes in 412 index cases with dominantly inherited cerebellar ataxias, we aimed to establish the relative frequencies of mutations in other genes, with an approach combining panel sequencing and TaqMan\u00ae polymerase chain reaction assay. We found relevant genetic variants in 59 patients (14.3%). The most frequently mutated were channel genes [CACNA1A (n = 16), KCND3 (n = 4), KCNC3 (n = 2) and KCNA1 (n = 2)]. Deletions in ITPR1 (n = 11) were followed by biallelic variants in SPG7 (n = 9). Variants in AFG3L2 (n = 7) came next in frequency, and variants were rarely found in STBN2 (n = 2), ELOVL5, FGF14, STUB1 and TTBK2 (n = 1 each). Interestingly, possible risk factor variants were detected in SPG7 and POLG. Clinical comparisons showed that ataxias due to channelopathies had a significantly earlier age at onset with an average of 24.6 years, versus 40.9 years for polyglutamine expansion spinocerebellar ataxias and 37.8 years for SPG7-related forms (P = 0.001). In contrast, disease duration was significantly longer in the former (20.5 years versus 9.3 and 13.7, P=0.001), though for similar functional stages, indicating slower progression of the disease. Of interest, intellectual deficiency was more frequent in channel spinocerebellar ataxias, while cognitive impairment in adulthood was similar among the three groups. Similar differences were found among a single gene group, comparing 23 patients with CACNA1A expansions (spinocerebellar ataxia 6) to 22 patients with CACNA1A point mutations, which had lower average age at onset (25.2 versus 47.3 years) with longer disease duration (18.7 versus 10.9), but lower severity indexes (0.39 versus 0.44), indicating slower progression of the disease. In conclusion, we identified relevant genetic variations in up to 15% of cases after exclusion of polyglutamine expansion spinocerebellar ataxias, and confirmed CACNA1A and SPG7 as major ataxia genes.

Linkage and association analyses provided converging evidence for a locus on chromosome Xq27.3. The minor allele A of rs1009776 was associated with an earlier onset (P\u2009=\u20091 \u00d7 10-5). The association with onset of dementia was replicated in an independent cohort of unrelated C9orf72 patients (P\u2009=\u20090.009). The protective major allele delayed the onset of dementia from 5 to 13\u2009years on average depending on the cohort considered. The same trend was observed in an independent cohort of C9orf72 patients with extreme deviation of the age at onset (P\u2009=\u20090.055). No association of rs1009776 was detected in GRN patients, suggesting that the effect of rs1009776 was restricted to the onset of dementia due to C9orf72. The minor allele A is associated with a higher SLITRK2 expression based on both expression quantitative trait loci (eQTL) databases and in-house expression studies performed on C9orf72 brain tissues. SLITRK2 encodes for a post-synaptic adhesion protein. We further show that synaptic vesicle glycoprotein 2 and synaptophysin, two synaptic vesicle proteins, were decreased in frontal cortex of C9orf72 patients carrying the minor allele. Upregulation of SLITRK2 might be associated with synaptic dysfunctions and drives adverse effects in C9orf72 patients that could be modulated in those carrying the protective allele. How the modulation of SLITRK2 expression affects synaptic functions and influences the disease onset of dementia in C9orf72 carriers will require further investigations. In summary, this study describes an original approach to detect modifier genes in rare diseases and reinforces rising links between C9orf72 and synaptic dysfunctions that might directly influence the occurrence of first symptoms.", + "language": "en", + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:34687211" +}, +{ + "id": "pmid:30347338", + "manubot_success": true, + "link": "https://www.ncbi.nlm.nih.gov/pubmed/30347338", + "title": "Response to the commentary \"The effect of C9orf72 intermediate repeat expansions in neurodegenerative and autoimmune diseases\" by Biasiotto G and Zanella I.", + "type": "article-journal", + "doi": "10.1016/j.msard.2018.10.007", + "authors": [ + ["Cinzia", "Tiloca"], + ["Melissa", "Sorosina"], + ["Federica", "Esposito"], + ["Silvia", "Peroni"], + ["Claudia", "Colombrita"], + ["Nicola", "Ticozzi"], + ["Antonia", "Ratti"], + ["Filippo", "Martinelli-Boneschi"], + ["Vincenzo", "Silani"] + ], + "publisher": "Multiple sclerosis and related disorders", + "issn": "2211-0356", + "date": "2018-10-14", + "abstract": "", + "language": "en", + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:30347338" +}, +{ + "id": "pmid:30252044", + "manubot_success": true, + "link": "https://www.ncbi.nlm.nih.gov/pubmed/30252044", + "title": "A C6orf10/LOC101929163 locus is associated with age of onset in C9orf72 carriers.", + "type": "article-journal", + "doi": "10.1093/brain/awy238", + "authors": [ + ["Ming", "Zhang"], + ["Raffaele", "Ferrari"], + ["Maria Carmela", "Tartaglia"], + ["Julia", "Keith"], + ["Ezequiel I", "Surace"], + ["Uri", "Wolf"], + ["Christine", "Sato"], + ["Mark", "Grinberg"], + ["Yan", "Liang"], + ["Zhengrui", "Xi"], + ["Kyle", "Dupont"], + ["Philip", "McGoldrick"], + ["Anna", "Weichert"], + ["Paul M", "McKeever"], + ["Raphael", "Schneider"], + ["Michael D", "McCorkindale"], + ["Claudia", "Manzoni"], + ["Rosa", "Rademakers"], + ["Neill R", "Graff-Radford"], + ["Dennis W", "Dickson"], + ["Joseph E", "Parisi"], + ["Bradley F", "Boeve"], + ["Ronald C", "Petersen"], + ["Bruce L", "Miller"], + ["William W", "Seeley"], + ["John C", "van Swieten"], + ["Jeroen", "van Rooij"], + ["Yolande", "Pijnenburg"], + ["Julie", "van der Zee"], + ["Christine", "Van Broeckhoven"], + ["Isabelle", "Le Ber"], + ["Vivianna", "Van Deerlin"], + ["EunRan", "Suh"], + ["Jonathan D", "Rohrer"], + ["Simon", "Mead"], + ["Caroline", "Graff"], + ["Linn", "\u00d6ijerstedt"], + ["Stuart", "Pickering-Brown"], + ["Sara", "Rollinson"], + ["Giacomina", "Rossi"], + ["Fabrizio", "Tagliavini"], + ["William S", "Brooks"], + ["Carol", "Dobson-Stone"], + ["Glenda M", "Halliday"], + ["John R", "Hodges"], + ["Olivier", "Piguet"], + ["Giuliano", "Binetti"], + ["Luisa", "Benussi"], + ["Roberta", "Ghidoni"], + ["Benedetta", "Nacmias"], + ["Sandro", "Sorbi"], + ["Amalia C", "Bruni"], + ["Daniela", "Galimberti"], + ["Elio", "Scarpini"], + ["Innocenzo", "Rainero"], + ["Elisa", "Rubino"], + ["Jordi", "Clarimon"], + ["Alberto", "Lle\u00f3"], + ["Agustin", "Ruiz"], + ["Isabel", "Hern\u00e1ndez"], + ["Pau", "Pastor"], + ["Monica", "Diez-Fairen"], + ["Barbara", "Borroni"], + ["Florence", "Pasquier"], + ["Vincent", "Deramecourt"], + ["Thibaud", "Lebouvier"], + ["Robert", "Perneczky"], + ["Janine", "Diehl-Schmid"], + ["Jordan", "Grafman"], + ["Edward D", "Huey"], + ["Richard", "Mayeux"], + ["Michael A", "Nalls"], + ["Dena", "Hernandez"], + ["Andrew", "Singleton"], + ["Parastoo", "Momeni"], + ["Zhen", "Zeng"], + ["John", "Hardy"], + ["Janice", "Robertson"], + ["Lorne", "Zinman"], + ["Ekaterina", "Rogaeva"] + ], + "publisher": "Brain : a journal of neurology", + "issn": "1460-2156", + "date": "2018-10-01", + "abstract": "The G4C2-repeat expansion in C9orf72 is the most common known cause of amyotrophic lateral sclerosis and frontotemporal dementia. The high phenotypic heterogeneity of C9orf72 patients includes a wide range in age of onset, modifiers of which are largely unknown. Age of onset could be influenced by environmental and genetic factors both of which may trigger DNA methylation changes at CpG sites. We tested the hypothesis that age of onset in C9orf72 patients is associated with some common single nucleotide polymorphisms causing a gain or loss of CpG sites and thus resulting in DNA methylation alterations. Combined analyses of epigenetic and genetic data have the advantage of detecting functional variants with reduced likelihood of false negative results due to excessive correction for multiple testing in genome-wide association studies. First, we estimated the association between age of onset in C9orf72 patients (n = 46) and the DNA methylation levels at all 7603 CpG sites available on the 450 k BeadChip that are mapped to common single nucleotide polymorphisms. This was followed by a genetic association study of the discovery (n = 144) and replication (n = 187) C9orf72 cohorts. We found that age of onset was reproducibly associated with polymorphisms within a 124.7 kb linkage disequilibrium block tagged by top-significant variation, rs9357140, and containing two overlapping genes (LOC101929163 and C6orf10). A meta-analysis of all 331 C9orf72 carriers revealed that every A-allele of rs9357140 reduced hazard by 30% (P = 0.0002); and the median age of onset in AA-carriers was 6 years later than GG-carriers. In addition, we investigated a cohort of C9orf72 negative patients (n = 2634) affected by frontotemporal dementia and/or amyotrophic lateral sclerosis; and also found that the AA-genotype of rs9357140 was associated with a later age of onset (adjusted P = 0.007 for recessive model). Phenotype analyses detected significant association only in the largest subgroup of patients with frontotemporal dementia (n = 2142, adjusted P = 0.01 for recessive model). Gene expression studies of frontal cortex tissues from 25 autopsy cases affected by amyotrophic lateral sclerosis revealed that the G-allele of rs9357140 is associated with increased brain expression of LOC101929163 (a non-coding RNA) and HLA-DRB1 (involved in initiating immune responses), while the A-allele is associated with their reduced expression. Our findings suggest that carriers of the rs9357140 GG-genotype (linked to an earlier age of onset) might be more prone to be in a pro-inflammatory state (e.g. by microglia) than AA-carriers.

Additionally, repetitive RNAs and dipeptide repeat proteins (DPRs), such as poly-GR, can be produced by this hexanucleotide expansion that disrupt a number of cellular processes, potentially contributing to neural degeneration. To better discern which of these mechanisms leads to disease-associated changes in patient brains, we analyzed gene expression data generated from the cortex and cerebellum. We found that transcripts encoding heat shock proteins (HSPs) regulated by the HSF1 transcription factor were significantly induced in C9ORF72-ALS/FTLD patients relative to both sporadic ALS/FTLD cases and controls. Treatment of human neurons with chemically synthesized DPRs was sufficient to activate a similar transcriptional response. Expression of GGGGCC repeats and also poly-GR in the brains of Drosophila lead to the upregulation of HSF1 and the same highly-conserved HSPs.

Most research has focused on the pathogenic effects of the resultant protein product(s); however, growing evidence indicates that expanded CAG repeats within mutant HTT mRNA and derived small CAG repeat RNAs (sCAG) participate in HD pathophysiology. The individual contribution of protein versus RNA toxicity to HD pathophysiology remains largely uncharacterized and the role of other classes of small RNAs (sRNA) that are strongly perturbed in HD is uncertain. Here, we demonstrate that sRNA produced in the putamen of HD patients (HD-sRNA-PT) are sufficient to induce HD pathology in vivo. Mice injected with HD-sRNA-PT show motor abnormalities, decreased levels of striatal HD-related proteins, disruption of the indirect pathway, and strong transcriptional abnormalities, paralleling human HD pathology. Importantly, we show that the specific blockage of sCAG mitigates HD-sRNA-PT neurotoxicity only to a limited extent. This observation prompted us to identify other sRNA species enriched in HD putamen with neurotoxic potential. We detected high levels of tRNA fragments (tRFs) in HD putamen, and we validated the neurotoxic potential of an Alanine derived tRF in vitro. These results highlight that HD-sRNA-PT are neurotoxic, and suggest that multiple sRNA species contribute to striatal dysfunction and general transcriptomic changes, favoring therapeutic strategies based on the blockage of sRNA-mediated toxicity.", + "language": "en", + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:33547932" }, { - "id": "omim:183090", - "manubot_success": false, - "link": "https://omim.org/entry/183090", - "note": "WARNING: Manubot does not support url:https://omim.org/entry/183090.

Epigenome modifiers, such as histone deacetylase inhibitors (HDACi), have improved pathology in a range of HD models. Yet in clinical trials, HDACi have failed to alleviate HD symptoms in patients. This study investigated potential reasons for the lack of translation of the therapeutic benefits of HDACi from lab to clinic. We analysed histone acetylation patterns of immuno-positive nuclei from brain sections and tissue microarrays from post-mortem human control and HD cases alongside several well-established HD models (OVT73 transgenic HD sheep, YAC128 mice, and an in vitro cell model expressing 97Q mutant huntingtin). Significant increases in histone H4 acetylation were observed in post-mortem HD cases, OVT73 transgenic HD sheep and in vitro models; these changes were absent in YAC128 mice. In addition, nuclear labelling for acetyl-histone H4 levels were inversely proportional to mutant huntingtin aggregate load in HD human cortex.

HD is caused by a CAG repeat expansion in the gene encoding the huntingtin protein. Homozygosity for the HD-causing mutation is extremely rare; thus, the majority of HD patients express the mutant huntingtin protein in addition to reduced levels of the non-pathogenic huntingtin protein. Deficits in synaptic plasticity, including hippocampal long-term potentiation (LTP), have been identified in various mouse models of HD and are thought to contribute to the debilitating cognitive symptoms associated with the disease. However, the bulk of these studies used N-terminal fragment or homozygous knock-in mouse models of HD at symptomatic ages, and our understanding of the onset and progression of synaptic plasticity deficits in the HD brain is lacking. To better understand the time-course of synaptic plasticity deficits in HD, as well as the impact of heterozygous and homozygous huntingtin mutations, we quantified basal synaptic connectivity, presynaptic release probability, presynaptically mediated post-tetanic potentiation (PTP) and postsynaptically mediated LTP at presymptomatic, early symptomatic and late symptomatic ages in heterozygous and homozygous Q175FDN knock-in HD mice. Our results demonstrate clear age-dependent effects of the HD-causing mutation on both short and long-term plasticity that generally emerge earlier in homozygous mice. Interestingly, deficits in presynaptic short-term plasticity were more closely linked to disease progression than deficits in postsynaptic LTP, and heterozygous mice were more susceptible to an LTP deficit when induced by high frequency stimulation compared to theta burst stimulation. To the best of our knowledge, the present study represents the most thorough characterization to date of the onset and progression of hippocampal synaptic plasticity deficits in a mouse model of HD, and should prove valuable to future studies exploring cellular mechanisms underlying the debilitating cognitive decline in HD.", + "language": "en", + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:31379510" }, { - "id": "omim:609893", - "manubot_success": false, - "link": "https://omim.org/entry/609893", - "note": "WARNING: Manubot does not support url:https://omim.org/entry/609893.

Expression of long polyglutamine repeat led to reduced ATP production and mitochondrial fragmentation. We observed an increased accumulation of damaged mitochondria in the lysosome that was coupled with lysosomal dysfunction. Importantly, reducing Drp1/Fis1-mediated mitochondrial damage significantly improved mitochondrial function and cell survival. Finally, reducing Fis1-mediated Drp1 recruitment to the mitochondria, using the selective inhibitor of this interaction, P110, improved mitochondrial structure in the cardiac tissue of R6/2 mice.

Methods- A single-center cohort of consecutive patients with ICH was retrospectively analyzed. Patients with available CT angiography, baseline, and follow-up noncontrast CT images available were included. Trained readers reviewed all the images for SS and HD presence, and the study population was classified into 4 groups: SS and HD negative (SS-HD-), SS positive only (SS+HD-), HD positive only (SS-HD+), and SS and HD positive (SS+HD+).

It has proved difficult, however, to determine whether the toxic form generated by polyQ expansion is a misfolded or avid-binding monomer, an \u03b1-helix-rich oligomer, or a \u03b2-sheet-rich amyloid fibril. Here we describe an engineered htt exon1 analog featuring a short polyQ sequence that nonetheless quickly forms amyloid fibrils and causes HD-like toxicity in rat neurons and Drosophila. Additional modifications within the polyQ segment produce htt exon1 analogs that populate only spherical oligomers and are non-toxic in cells and flies. Furthermore, in mixture with expanded-polyQ htt exon1, the latter analogs in vitro suppress amyloid formation and promote oligomer formation, and in vivo rescue neurons and flies expressing mhtt exon1 from dysfunction and death. Thus, in our experiments, while htt exon1 toxicity tracks with aggregation propensity, it does so in spite of the toxic construct's possessing polyQ tracts well below those normally considered to be disease-associated. That is, aggregation propensity proves to be a more accurate surrogate for toxicity than is polyQ repeat length itself, strongly supporting a major toxic role for htt exon1 aggregation in HD. In addition, the results suggest that the aggregates that are most toxic in these model systems are amyloid-related. These engineered analogs are novel tools for mapping properties of polyQ self-assembly intermediates and products that should similarly be useful in the analysis of other expanded polyQ diseases.

The standard explanation for HD is that eggs of the responder strains lack an abundant pool of piRNAs corresponding to the asymmetric TE families transmitted solely by sperm. However, there are several strains of D. virilis that lack asymmetric TEs, but exhibit a \"neutral\" cytotype that confers resistance to HD. To characterize the mechanism of resistance to HD, we performed a comparative analysis of the landscape of ovarian small RNAs in strains that vary in their resistance to HD mediated sterility. We demonstrate that resistance to HD cannot be solely explained by a maternal piRNA pool that matches the assemblage of TEs that likely cause HD. In support of this, we have witnessed a cytotype shift from neutral (N) to susceptible (M) in a strain devoid of all major TEs implicated in HD. This shift occurred in the absence of significant change in TE copy number and expression of piRNAs homologous to asymmetric TEs. Instead, this shift is associated with a change in the chromatin profile of repeat sequences unlikely to be causative of paternal induction.

Chronic activation of endoplasmic reticulum (ER) stress by mutant Htt (mHtt) results in cellular dysfunction and ultimately cell death.

Our previous studies demonstrated that mHtt caused PDI to accumulate at mitochondria-associated ER membranes and triggered cell death, and that modulating PDI activity using small molecules protected cells again mHtt toxicity in cell and brain slice models of HD. In this study, we demonstrated that PDI is upregulated in the HD human brain, in cell and mouse models. Chronic administration of a reversible, brain penetrable small molecule PDI modulator, LOC14 (20 mg/kg/day), significantly improved motor function, attenuated brain atrophy and extended survival in the N171-82Q HD mice.

Ube2W is the only ubiquitin conjugating enzyme (E2) known to ubiquitinate substrates at their amino (N)-termini, likely favoring substrates with disordered N-termini. By virtue of its N-terminal polyQ domain, HTT has an intrinsically disordered amino terminus.

In cultured cells, deficiency of Ube2W activity markedly decreases mHTT aggregate formation and increases the level of soluble monomers, while reducing mHTT-induced cytotoxicity. Consistent with this result, the absence of Ube2W in HdhQ200 KI mice significantly increases levels of soluble monomeric mHTT while reducing insoluble oligomeric species.

These findings are consistent with the HD mutation affecting structural aspects of the amino-terminal region of the protein, and support the concept that modulating mutant HTT conformation might provide novel therapeutic and diagnostic opportunities.

Remove loose rugs and clutter from the individual's home and minimize or eliminate the need for stairs to help prevent falls and other injuries; physical therapy evaluation and treatment for mobility issues; speech therapy, communication devices, and environmental modifications for dysarthria; speech-language pathology and nutrition referrals for dysphagia; food should be prepared in such a manner as to prevent choking; feeding changes when needed to minimize risk of aspiration; driving may need to be curtailed or limited to prevent risk of accidents; planning for financial matters; environmental interventions for cognitive issues; antidepressants, antipsychotics, mood stabilizers (lithium, valproic acid, carbamazepine, and lamotrigine), electroconvulsive therapy, and occasionally stimulants may improve psychiatric manifestations. Education about the course of disease; social work and care coordination support. Surveillance: Annual evaluation or more frequently as needed to assess motor skills including gait and abnormal movements; physical therapy assessment of mobility and appropriate strategies or devices to minimize falls; assess cognitive skills and driving safety to assure that affected individuals do not present a danger to themselves or others; assess weight, nutrition, swallowing, and risk of aspiration in order to implement feeding changes when necessary; assess for psychiatric manifestations, including mood, suicidality, anxiety, irritability, and apathy; assess sleep and sexual concerns; assess family needs; assess planning for future (financial, legal issues). Agents/circumstances to avoid: Any agents that increase ataxia should be used with caution; begin psychoactive medicines at lower doses and increase doses carefully; minimize polypharmacy, which may increase the risk of delirium., HDL2 is inherited in an autosomal dominant manner. Most individuals with HDL2 have an affected parent. At conception, each child of an individual with HDL2 has a 50% chance of inheriting the HDL2-causing allele. Offspring who inherit a pathogenic (full-penetrance) HDL2-causing allele (\u226540 CTG repeats) are considered at risk of developing HDL2 in their lifetime; offspring who inherit an allele of questionable significance (29-39 CTG repeats) may or may not develop manifestations of HDL2. Testing of asymptomatic adults at risk for HDL2 is possible once a heterozygous expansion of a CTG repeat in JPH3 has been identified in an affected family member. Testing for the JPH3 CTG repeat expansion in the absence of definite manifestations of the disease is predictive testing. Prudence suggests following the same genetic testing guidelines used for HD, including counseling prior to testing, a confidant to serve as a social support, and availability of counseling following the disclosure of genetic results. If the presence of an HDL2-causing allele has been confirmed in the affected parent or in an affected relative of the at-risk parent, prenatal and preimplantation genetic testing are possible.", - "language": "eng", - "note": "PMID: 20301701\nThis CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: url:https://www.ncbi.nlm.nih.gov/books/NBK1529" + "publisher": "PloS one", + "issn": "1932-6203", + "date": "2017-04-13", + "abstract": "Alterations in mitochondrial respiration are an important hallmark of Huntington's disease (HD), one of the most common monogenetic causes of neurodegeneration.

The integrated respiratory chain function of the human vastus lateralis muscle was measured by high-resolution respirometry (HRR) in freshly taken fine-needle biopsies from seven pre-manifest HD expansion mutation carriers and nine controls. The respiratory parameters were unaffected. For comparison skeletal muscle isolated from HD knock-in mice (HdhQ111) as well as a broader spectrum of tissues including cortex, liver and heart muscle were examined by HRR. Significant changes of mitochondrial respiration in the HdhQ knock-in mouse model were restricted to the liver and the cortex. Mitochondrial mass as quantified by mitochondrial DNA copy number and citrate synthase activity was stable in murine HD-model tissue compared to control. mRNA levels of key enzymes were determined to characterize mitochondrial metabolic pathways in HdhQ mice. We demonstrated the feasibility to perform high-resolution respirometry measurements from small human HD muscle biopsies. Furthermore, we conclude that alterations in respiratory parameters of pre-manifest human muscle biopsies are rather limited and mirrored by a similar absence of marked alterations in HdhQ skeletal muscle.

Therefore, counteracting mutant huntingtin (mHtt)-induced oxidative stress and mitochondrial dysfunction appears as a new approach to treat this devastating disease. Interestingly, mild mitochondrial uncoupling improves neuronal resistance to stress and facilitates neuronal survival. Mild mitochondrial uncoupling can be induced by the proper dose of 2,4-dinitrophenol (DNP), a proton ionophore that was previously used for weight loss. In this study, we evaluated the effects of chronic administration of DNP at three doses (0.5, 1, 5mg/kg/day) on mHtt-induced behavioral deficits and cellular abnormalities in the N171-82Q HD mouse model. DNP at a low dose (1mg/kg/day) significantly improved motor function and preserved medium spiny neuronal marker DARPP32 and postsynaptic protein PSD95 in the striatum of HD mice. Further mechanistic study suggests that DNP at this dose reduced oxidative stress in HD mice, which was indicated by reduced levels of F2-isoprostanes in the brain of HD mice treated with DNP.

This large amount of implicated genes accounts for heterogeneous clinical presentations, making genotype-phenotype correlations a major challenge in the field. While polyglutamine ataxias, linked to CAG repeat expansions in genes such as ATXN1, ATXN2, ATXN3, ATXN7, CACNA1A and TBP, have been extensively characterized in large cohorts, there is a need for comprehensive assessment of frequency and phenotype of more 'conventional' ataxias. After exclusion of CAG/polyglutamine expansions in spinocerebellar ataxia genes in 412 index cases with dominantly inherited cerebellar ataxias, we aimed to establish the relative frequencies of mutations in other genes, with an approach combining panel sequencing and TaqMan\u00ae polymerase chain reaction assay. We found relevant genetic variants in 59 patients (14.3%). The most frequently mutated were channel genes [CACNA1A (n = 16), KCND3 (n = 4), KCNC3 (n = 2) and KCNA1 (n = 2)]. Deletions in ITPR1 (n = 11) were followed by biallelic variants in SPG7 (n = 9).

Interestingly, possible risk factor variants were detected in SPG7 and POLG. Clinical comparisons showed that ataxias due to channelopathies had a significantly earlier age at onset with an average of 24.6 years, versus 40.9 years for polyglutamine expansion spinocerebellar ataxias and 37.8 years for SPG7-related forms (P = 0.001). In contrast, disease duration was significantly longer in the former (20.5 years versus 9.3 and 13.7, P=0.001), though for similar functional stages, indicating slower progression of the disease. Of interest, intellectual deficiency was more frequent in channel spinocerebellar ataxias, while cognitive impairment in adulthood was similar among the three groups. Similar differences were found among a single gene group, comparing 23 patients with CACNA1A expansions (spinocerebellar ataxia 6) to 22 patients with CACNA1A point mutations, which had lower average age at onset (25.2 versus 47.3 years) with longer disease duration (18.7 versus 10.9), but lower severity indexes (0.39 versus 0.44), indicating slower progression of the disease. In conclusion, we identified relevant genetic variations in up to 15% of cases after exclusion of polyglutamine expansion spinocerebellar ataxias, and confirmed CACNA1A and SPG7 as major ataxia genes.

Animal models demonstrate that HTT is vital to brain development; however, this has not been studied in humans. Moreover, evidence suggests that triplet repeat genes may have been vital in evolution of the human brain. Here we evaluate brain structure using magnetic resonance imaging and brain function using cognitive tests in a sample of school-aged children ages 6 to 18 years old. DNA samples were processed to quantify the number of CAG repeats within HTT. We find that the number of repeats in HTT, below disease threshold, confers advantageous changes in brain structure and general intelligence (IQ): the higher the number of repeats, the greater the change in brain structure, and the higher the IQ. The pattern of structural brain changes associated with HTT is strikingly different between males and females. HTT may confer an advantage or a disadvantage depending on the repeat length, playing a key role in either the evolution of a superior human brain or development of a uniquely human brain disease. \u00a9 2016 Wiley Periodicals, Inc.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:30109267" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:27870408" }, { - "id": "pmid:39913612", + "id": "pmid:27681197", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/39913612", - "title": "ALS plasma biomarkers reveal neurofilament and pTau correlate with disease onset and progression.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/27681197", + "title": "Mycobacterium tuberculosis multi-drug-resistant strain M induces IL-17", "type": "article-journal", - "doi": "10.1002/acn3.70001", + "doi": "10.1111/cei.12873", "authors": [ - ["Eleanor V", "Thomas"], - ["Changee", "Han"], - ["Woo Jae", "Kim"], - ["Seneshaw", "Asress"], - ["Yingjie", "Li"], - ["Jennifer A", "Taylor"], - ["Marla", "Gearing"], - ["Christina N", "Fournier"], - ["Zachary T", "McEachin"], - ["Nicholas T", "Seyfried"], - ["Jonathan D", "Glass"] + ["J I", "Basile"], + ["D", "Kviatcovsky"], + ["M M", "Romero"], + ["L", "Balboa"], + ["J", "Monteserin"], + ["V", "Ritacco"], + ["B", "Lopez"], + ["C", "Sabio y Garc\u00eda"], + ["A", "Garc\u00eda"], + ["M", "Vescovo"], + ["P G", "Montaner"], + ["D", "Palmero"], + ["M", "Del Carmen Sasiain"], + ["S", "de la Barrera"] ], - "publisher": "Annals of clinical and translational neurology", - "issn": "2328-9503", - "date": "2025-02-06", - "abstract": "We performed a pilot screen to assess the utility of the NULISA\u2122 (Nucleic-acid-Linked Immuno-Sandwich Assay) platform in the identification of amyotrophic lateral sclerosis (ALS) biomarkers.", + "publisher": "Clinical and experimental immunology", + "issn": "1365-2249", + "date": "2016-11-02", + "abstract": "We have reported previously that T cells from patients with multi-drug-resistant tuberculosis (MDR-TB) express high levels of interleukin (IL)-17 in response to the MDR strain M (Haarlem family) of Mycobacterium tuberculosis (M. tuberculosis).

The variability of age at onset and phenotypic presentations is a hallmark of C9orf72 disease. In this study, we aimed to identify modifying factors of disease onset in C9orf72 carriers using a family-based approach, in pairs of C9orf72 carrier relatives with concordant or discordant age at onset. Linkage and association analyses provided converging evidence for a locus on chromosome Xq27.3. The minor allele A of rs1009776 was associated with an earlier onset (P\u2009=\u20091 \u00d7 10-5). The association with onset of dementia was replicated in an independent cohort of unrelated C9orf72 patients (P\u2009=\u20090.009). The protective major allele delayed the onset of dementia from 5 to 13\u2009years on average depending on the cohort considered. The same trend was observed in an independent cohort of C9orf72 patients with extreme deviation of the age at onset (P\u2009=\u20090.055). No association of rs1009776 was detected in GRN patients, suggesting that the effect of rs1009776 was restricted to the onset of dementia due to C9orf72. The minor allele A is associated with a higher SLITRK2 expression based on both expression quantitative trait loci (eQTL) databases and in-house expression studies performed on C9orf72 brain tissues. SLITRK2 encodes for a post-synaptic adhesion protein. We further show that synaptic vesicle glycoprotein 2 and synaptophysin, two synaptic vesicle proteins, were decreased in frontal cortex of C9orf72 patients carrying the minor allele. Upregulation of SLITRK2 might be associated with synaptic dysfunctions and drives adverse effects in C9orf72 patients that could be modulated in those carrying the protective allele. How the modulation of SLITRK2 expression affects synaptic functions and influences the disease onset of dementia in C9orf72 carriers will require further investigations.

In contrast to many proteins that have only a single S-nitrosylation or S-acylation site, we identified sites along much of the length of Htt. Moreover, analysis of cells expressing full-length Htt or a large N-terminal fragment of Htt shows that polyQ expansion strongly increases Htt S-nitrosylation. This effect appears to be general since it is also observed in Ataxin-1, which causes spinocerebellar ataxia type 1 (SCA1) when its polyQ tract is expanded. Overexpression of nitric oxide synthase increases the S-nitrosylation of normal Htt and the frequency of conspicuous juxtanuclear inclusions of Htt N-terminal fragments in transfected cells.

The high phenotypic heterogeneity of C9orf72 patients includes a wide range in age of onset, modifiers of which are largely unknown. Age of onset could be influenced by environmental and genetic factors both of which may trigger DNA methylation changes at CpG sites. We tested the hypothesis that age of onset in C9orf72 patients is associated with some common single nucleotide polymorphisms causing a gain or loss of CpG sites and thus resulting in DNA methylation alterations. Combined analyses of epigenetic and genetic data have the advantage of detecting functional variants with reduced likelihood of false negative results due to excessive correction for multiple testing in genome-wide association studies. First, we estimated the association between age of onset in C9orf72 patients (n = 46) and the DNA methylation levels at all 7603 CpG sites available on the 450 k BeadChip that are mapped to common single nucleotide polymorphisms. This was followed by a genetic association study of the discovery (n = 144) and replication (n = 187) C9orf72 cohorts. We found that age of onset was reproducibly associated with polymorphisms within a 124.7 kb linkage disequilibrium block tagged by top-significant variation, rs9357140, and containing two overlapping genes (LOC101929163 and C6orf10). A meta-analysis of all 331 C9orf72 carriers revealed that every A-allele of rs9357140 reduced hazard by 30% (P = 0.0002); and the median age of onset in AA-carriers was 6 years later than GG-carriers. In addition, we investigated a cohort of C9orf72 negative patients (n = 2634) affected by frontotemporal dementia and/or amyotrophic lateral sclerosis; and also found that the AA-genotype of rs9357140 was associated with a later age of onset (adjusted P = 0.007 for recessive model). Phenotype analyses detected significant association only in the largest subgroup of patients with frontotemporal dementia (n = 2142, adjusted P = 0.01 for recessive model). Gene expression studies of frontal cortex tissues from 25 autopsy cases affected by amyotrophic lateral sclerosis revealed that the G-allele of rs9357140 is associated with increased brain expression of LOC101929163 (a non-coding RNA) and HLA-DRB1 (involved in initiating immune responses), while the A-allele is associated with their reduced expression. Our findings suggest that carriers of the rs9357140 GG-genotype (linked to an earlier age of onset) might be more prone to be in a pro-inflammatory state (e.g. by microglia) than AA-carriers.

Therefore, other factors must influence the pathogenic process. We asked whether these factors were related to natural biological variation in the sensory-motor system. In 243 participants (96 premanifest and 35 manifest HD; 112 controls), sensory-motor structural MRI, tractography, resting-state fMRI, electrophysiology (including SEP amplitudes), motor score ratings, and grip force as sensory-motor performance were measured. Following individual modality analyses, we used principal component analysis (PCA) to identify patterns associated with sensory-motor performance, and manifest versus premanifest HD discrimination. We did not detect longitudinal differences over 12 months. PCA showed a pattern of loss of caudate, grey and white matter volume, cortical thickness in premotor and sensory cortex, and disturbed diffusivity in sensory-motor white matter tracts that was connected to CAG repeat length. Two further major principal components appeared in controls and HD individuals indicating that they represent natural biological variation unconnected to the HD mutation. One of these components did not influence HD while the other non-CAG-driven component of axial versus radial diffusivity contrast in white matter tracts were associated with sensory-motor performance and manifest HD. The first component reflects the expected CAG expansion effects on HD pathogenesis. One non-CAG-driven component reveals an independent influence on pathogenesis of biological variation in white matter tracts and merits further investigation to delineate the underlying mechanism and the potential it offers for disease modification.

Although there is general agreement that HTT toxicity resides primarily in N-terminal fragments such as the HTT exon1 protein, there is no consensus on the nature of the physical states of HTT exon1 that are induced by polyQ expansion, nor on which of these states might be responsible for toxicity. One hypothesis is that polyQ expansion induces an alternative, toxic conformation in the HTT exon1 monomer. Alternative hypotheses posit that the toxic species is one of several possible aggregated states. Defining the nature of the toxic species is particularly challenging because of facile interconversion between physical states as well as challenges to identifying these states, especially in vivo. Here we describe the use of fluorescence correlation spectroscopy (FCS) to characterize the detailed time and repeat length dependent self-association of HTT exon1-like fragments both with chemically synthesized peptides in vitro and with cell-produced proteins in extracts and in living cells. We find that, in vitro, mutant HTT exon1 peptides engage in polyQ repeat length dependent dimer and tetramer formation, followed by time dependent formation of diffusible spherical and fibrillar oligomers and finally by larger, sedimentable amyloid fibrils. For expanded polyQ HTT exon1 expressed in PC12 cells, monomers are absent, with tetramers being the smallest molecular form detected, followed in the incubation time course by small, diffusible aggregates at 6-9 hours and larger, sedimentable aggregates that begin to build up at 12 hrs. In these cell cultures, significant nuclear DNA damage appears by 6 hours, followed at later times by caspase 3 induction, mitochondrial dysfunction, and cell death. Our data thus defines limits on the sizes and concentrations of different physical states of HTT exon1 along the reaction profile in the context of emerging cellular distress. The data provide some new candidates for the toxic species and some new reservations about more well-established candidates.

We found that, as with clinical onset, HD age at death is determined by expanded CAG-repeat length and has no contribution from the normal CAG allele. Surprisingly, disease duration is independent of the mutation's length. It is also unaffected by a strong genetic modifier of HD motor onset. These findings suggest two parsimonious alternatives. (1) HD pathogenesis is driven by mutant huntingtin, but before or near motor onset, sufficient CAG-driven damage occurs to permit CAG-independent processes and then lead to eventual death. In this scenario, some pathological changes and their clinical correlates could still worsen in a CAG-driven manner after disease onset, but these CAG-related progressive changes do not themselves determine duration. Alternatively, (2) HD pathogenesis is driven by mutant huntingtin acting in a CAG-dependent manner with different time courses in multiple cell types, and the cellular targets that lead to motor onset and death are different and independent.

Here, we observe similar inverse correlations between CCCTCT repeat length with age at onset and age at death and no obvious correlation with disease duration. To gain insight into repeat instability in XDP we performed comprehensive quantitative analyses of somatic instability of the XDP CCCTCT repeat in blood and in seventeen brain regions from affected males.

The brain exhibits regional-specific patterns of instability that are broadly similar across individuals, with cerebellum exhibiting low instability and cortical regions exhibiting relatively high instability. The spectrum of somatic instability in the brain includes a high proportion of moderate repeat length changes of up to 5 repeats, as well as expansions of\u2009~\u200920-\u2009>\u2009100 repeats and contractions of\u2009~\u200920-40 repeats at lower frequencies.

The striatum receives excitatory input from cortex and thalamus, and the role of the former has been well-studied in HD. Here, we report that mutated huntingtin alters function of thalamostriatal connections. We used a novel thalamostriatal (T-S) coculture and an established corticostriatal (C-S) coculture, generated from YAC128 HD and WT (FVB/NJ background strain) mice, to investigate excitatory neurotransmission onto striatal SPN. SPN in T-S coculture from WT mice showed similar mini-excitatory postsynaptic current (mEPSC) frequency and amplitude as in C-S coculture; however, both the frequency and amplitude were significantly reduced in YAC128 T-S coculture. Further investigation in T-S coculture showed similar excitatory synapse density in WT and YAC128 SPN dendrites by immunostaining, suggesting changes in total dendritic length or probability of release as possible explanations for mEPSC frequency changes. Synaptic N-methyl-D-aspartate receptor (NMDAR) current was similar, but extrasynaptic current, associated with cell death signaling, was enhanced in YAC128 SPN in T-S coculture. Employing optical stimulation of cortical versus thalamic afferents and recording from striatal SPN in brain slice, we found increased glutamate release probability and reduced AMPAR/NMDAR current ratios in thalamostriatal synapses, most prominently in YAC128. Enhanced extrasynaptic NMDAR current in YAC128 SPN was apparent with both cortical and thalamic stimulation.

A point mutation in the MLH3 endonuclease domain completely eliminated CAG expansion in the brain and peripheral tissues of a HD knock-in mouse model (HttQ111).

The individual contribution of protein versus RNA toxicity to HD pathophysiology remains largely uncharacterized and the role of other classes of small RNAs (sRNA) that are strongly perturbed in HD is uncertain. Here, we demonstrate that sRNA produced in the putamen of HD patients (HD-sRNA-PT) are sufficient to induce HD pathology in vivo. Mice injected with HD-sRNA-PT show motor abnormalities, decreased levels of striatal HD-related proteins, disruption of the indirect pathway, and strong transcriptional abnormalities, paralleling human HD pathology. Importantly, we show that the specific blockage of sCAG mitigates HD-sRNA-PT neurotoxicity only to a limited extent. This observation prompted us to identify other sRNA species enriched in HD putamen with neurotoxic potential. We detected high levels of tRNA fragments (tRFs) in HD putamen, and we validated the neurotoxic potential of an Alanine derived tRF in vitro.

In this study, we took an alternative approach focusing on symptom complexes and searched for modifiers of cognitive impairment and psychiatric symptoms in a well-described cohort of Danish HD gene-expansion carriers.

In several neurodegenerative disorders, including Parkinson's disease and Alzheimer's disease, elevated levels of RTP801 have been observed, which suggests a role for RTP801 in neuronal death. Neuronal death is also a pathological hallmark in Huntington's disease (HD), an inherited neurodegenerative disorder caused by a CAG repeat expansion in the huntingtin gene. Currently, the exact mechanisms underlying mutant huntingtin (mhtt)-induced toxicity are still unclear. Here, we investigated whether RTP801 is involved in (mhtt)-induced cell death. Ectopic exon-1 mhtt elevated RTP801 mRNA and protein levels in nerve growth factor (NGF)-differentiated PC12 cells and in rat primary cortical neurons. In neuronal PC12 cells, mhtt also contributed to RTP801 protein elevation by reducing its proteasomal degradation rate, in addition to promoting RTP801 gene expression. Interestingly, silencing RTP801 expression with short hairpin RNAs (shRNAs) blocked mhtt-induced cell death in NGF-differentiated PC12 cells. However, RTP801 protein levels were not altered in the striatum of Hdh(Q7/Q111) and R6/1 mice, two HD models that display motor deficits but not neuronal death. Importantly, RTP801 protein levels were elevated in both neural telencephalic progenitors differentiated from HD patient-derived induced pluripotent stem cells and in the putamen and cerebellum of human HD postmortem brains.

Inherited allele length is inversely proportional to age at onset, and frequent germline expansions account for the striking anticipation observed in affected families. Expanded disease associated alleles are also somatically unstable via a pathway that is age dependent and tissue specific, and also appears to be expansion biased. Somatic expansions are thought to contribute toward both tissue specificity and disease progression. Here we have examined the somatic mutational dynamics in brain and peripheral tissues from an allelic series of R6/2 HD transgenic mice inheriting from 52 to >700 CAG repeats. We found age-dependent, tissue-specific somatic instability, with particularly large expansions observed in the striatum and cortex. We also found a positive increase in somatic instability with increasing allele length. Surprisingly, however, the degree of somatic variation did not increase in a linear fashion, but leveled off with increasing allele length. Most unexpectedly, the almost exclusive bias toward the accumulation of expansions observed in mice inheriting smaller alleles was lost, and a high frequency of large somatic contractions was observed in mice inheriting very large alleles (>500 repeats). These data highlight the bidirectional nature of CAG\u2022CTG repeat instability and the subtle balance that exists between expansion and contraction in vivo.

We found that Htt is required in ESC for the proper deposition of histone H3K27me3 at a subset of 'bivalent' loci but in NPC it is needed at 'bivalent' loci for both the proper maintenance and the appropriate removal of this mark.

HD is caused by a CAG repeat expansion in the gene encoding the huntingtin protein. Homozygosity for the HD-causing mutation is extremely rare; thus, the majority of HD patients express the mutant huntingtin protein in addition to reduced levels of the non-pathogenic huntingtin protein. Deficits in synaptic plasticity, including hippocampal long-term potentiation (LTP), have been identified in various mouse models of HD and are thought to contribute to the debilitating cognitive symptoms associated with the disease. However, the bulk of these studies used N-terminal fragment or homozygous knock-in mouse models of HD at symptomatic ages, and our understanding of the onset and progression of synaptic plasticity deficits in the HD brain is lacking. To better understand the time-course of synaptic plasticity deficits in HD, as well as the impact of heterozygous and homozygous huntingtin mutations, we quantified basal synaptic connectivity, presynaptic release probability, presynaptically mediated post-tetanic potentiation (PTP) and postsynaptically mediated LTP at presymptomatic, early symptomatic and late symptomatic ages in heterozygous and homozygous Q175FDN knock-in HD mice. Our results demonstrate clear age-dependent effects of the HD-causing mutation on both short and long-term plasticity that generally emerge earlier in homozygous mice. Interestingly, deficits in presynaptic short-term plasticity were more closely linked to disease progression than deficits in postsynaptic LTP, and heterozygous mice were more susceptible to an LTP deficit when induced by high frequency stimulation compared to theta burst stimulation.

Loss of HTT function in Drosophila disrupts starvation-induced autophagy in larvae and conditional knockout of HTT in the mouse CNS causes characteristic cellular hallmarks of disrupted autophagy, including an accumulation of striatal p62/SQSTM1 over time. We observe that specific domains of HTT have structural similarities to yeast Atg proteins that function in selective autophagy, and in particular that the C-terminal domain of HTT shares structural similarity to yeast Atg11, an autophagic scaffold protein. To explore possible functional similarity between HTT and Atg11, we investigated whether the C-terminal domain of HTT interacts with mammalian counterparts of yeast Atg11-interacting proteins. Strikingly, this domain of HTT coimmunoprecipitates with several key Atg11 interactors, including the Atg1/Unc-51-like autophagy activating kinase 1 kinase complex, autophagic receptor proteins, and mammalian Atg8 homologs. Mutation of a phylogenetically conserved WXXL domain in a C-terminal HTT fragment reduces coprecipitation with mammalian Atg8 homolog GABARAPL1, suggesting a direct interaction.

Therefore we investigated the impact of a robust stressor (i.e. restraint) on the onset and progression of a range of behavioral phenotypes in R6/1 transgenic HD mice. Restraint was administered for 1h daily from 6weeks of age and continued until R6/1 mice were clearly motor symptomatic at 14weeks of age. Serum corticosterone levels in both R6/1 and WT littermates were elevated immediately after the last restraint session and weight gain was suppressed in restrained animals throughout the treatment period. Motor coordination and locomotor activity were enhanced by chronic restraint in males, regardless of genotype. However, there was no effect of restraint on motor performances in female animals. At 8weeks of age, olfactory sensitivity was impaired by restraint in R6/1 HD female mice, but not in WT mice. In male R6/1 mice, the olfactory deficit was exacerbated by restraint and olfaction was also impaired in male WT mice. The development of deficits in saccharin preference, Y-maze memory, nest-building and sexually-motivated vocalizations was unaffected by chronic restraint in R6/1 and had little impact on such behavioral performances in WT animals. We provide evidence that chronic stress can negatively modulate specific endophenotypes in HD mice, while the same functions were affected to a lesser extent in WT mice.

Expression of long polyglutamine repeat led to reduced ATP production and mitochondrial fragmentation. We observed an increased accumulation of damaged mitochondria in the lysosome that was coupled with lysosomal dysfunction. Importantly, reducing Drp1/Fis1-mediated mitochondrial damage significantly improved mitochondrial function and cell survival. Finally, reducing Fis1-mediated Drp1 recruitment to the mitochondria, using the selective inhibitor of this interaction, P110, improved mitochondrial structure in the cardiac tissue of R6/2 mice.

Female mice (WT and R6/1) appeared to be protected from the impacts of CORT treatment in all our hippocampal measures. Overall, our data demonstrate that treatment with corticosterone is able to modulate the onset of HD symptomatology. We present the first evidence of a male-specific vulnerability to stress impacting on the development of short-term memory deficits in HD. More generally, we found that female mice were protected from the detrimental effects of CORT treatment on a variety of hippocampus-based measures. Hippocampal plasticity and memory in HD may be more susceptible to the impacts of stress in a sex-dependent manner.

Using a conditional transgenic mouse model of HD, in which the mice express full-length human mHTT from a bacterial artificial chromosome transgene (BACHD), we genetically reduced mHTT expression in neuronal populations in the striatum, cortex or both.

MMs isolated from brains of aged Hdh Q111/Q111 knock-in mice showed a significant decrease in 1,6-diphenyl-hexatriene (DPH) anisotropy, which is inversely correlated with membrane fluidity. Similar increases in MM fluidity were observed in striatal STHdh Q111/Q111 cells as well as in MMs isolated from brains of BACHD transgenic rats.

In both models, treatment with olesoxime restored HD-specific changes in MMs. Accordingly, olesoxime significantly counteracted the mhtt-induced increase in MM fluidity of MMs isolated from brains of BACHD rats after 12 months of treatment in vivo, possibly by enhancing MM cholesterol levels.

However, there are several strains of D. virilis that lack asymmetric TEs, but exhibit a \"neutral\" cytotype that confers resistance to HD. To characterize the mechanism of resistance to HD, we performed a comparative analysis of the landscape of ovarian small RNAs in strains that vary in their resistance to HD mediated sterility. We demonstrate that resistance to HD cannot be solely explained by a maternal piRNA pool that matches the assemblage of TEs that likely cause HD. In support of this, we have witnessed a cytotype shift from neutral (N) to susceptible (M) in a strain devoid of all major TEs implicated in HD. This shift occurred in the absence of significant change in TE copy number and expression of piRNAs homologous to asymmetric TEs.

Here we investigated the role of NER in modulating expansions of threshold-length (CTG\u00b7CAG) repeats in yeast. We show that both the global genome and transcription-coupled repair subpathways promote expansions of threshold-length TNRs. Furthermore, NER works with the 26S proteasome to drive expansions, based on analysis of double mutants defective in both pathways, and of Rad23, a protein involved in both NER and the shuttling of ubiquitinated proteins to the proteasome. This work provides the first evidence that both subpathways of NER can promote threshold-length TNR expansions and that NER interacts with the proteasome to drive expansions.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:29494703" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:24359926" }, { - "id": "pmid:29480204", + "id": "pmid:24314096", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/29480204", - "title": "Early Neurodegeneration in R6/2 Mice Carrying the Huntington's Disease Mutation with a Super-Expanded CAG Repeat, Despite Normal Lifespan.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/24314096", + "title": "Clinical and genetic features of Huntington disease in Sri Lanka.", "type": "article-journal", - "doi": "10.3233/jhd-170265", + "doi": "10.1186/1471-2377-13-191", "authors": [ - ["Catherine", "Kielar"], - ["A Jennifer", "Morton"] + ["Dulika S", "Sumathipala"], + ["Rohan W", "Jayasekara"], + ["Vajira H W", "Dissanayake"] ], - "publisher": "Journal of Huntington's disease", - "issn": "1879-6400", - "date": "2018-01-01", - "abstract": "The threshold of CAG repeat expansion in the HTT gene that causes HD is 36 CAG repeats, although 'superlong' expansions are found in individual neurons in postmortem brains.

Inclusion pathology also differed from 250 CAG repeat mice, being dominated by a novel kind of extranuclear neuronal inclusion (nENNI) that resembles a class of aggregate seen in patients with the adult onset form of HD. Here, we characterised neuropathology in R6/2 mice with >400 CAG repeats using light and electron microscopy. nENNIs were found with increased frequency and wider distribution with age. Some nENNIs appear to 'mature' as the disease develops, developing a multi-layered cored structure. Mice with superlong CAG repeats do not develop clinical signs until they are around 30-40 weeks of age, and they attain a normal life span (>2 years). Nevertheless, they show brain atrophy and unequivocal neuron loss from the striatum and cortex by 22 weeks of age, an age at which similar pathology is seen in 250 CAG repeat mice.

These sequences mutate by changing the number of repeats not just between generations, but also during the lifetime of affected individuals. Levels of somatic instability contribute to disease onset and progression but as changes are tissue-specific, age- and repeat length-dependent, interpretation of the level of somatic instability in an individual is confounded by these considerations. Mathematical models, fitted to CTG repeat length distributions derived from blood DNA, from a large cohort of DM1-affected or at risk individuals, have recently been used to quantify inherited repeat lengths and mutation rates. Taking into account age, the estimated mutation rates are lower than predicted among individuals with small alleles (inherited repeat lengths less than 100 CTGs), suggesting that these rates may be suppressed at the lower end of the disease-causing range. In this study, we propose that a length-specific effect operates within this range and tested this hypothesis using a model comparison approach. To calibrate the extended model, we used data derived from blood DNA from DM1 individuals and, for the first time, buccal DNA from HD individuals. In a novel application of this extended model, we identified individuals whose effective repeat length, with regards to somatic instability, is less than their actual repeat length. A plausible explanation for this distinction is that the expanded repeat tract is compromised by interruptions or other unusual features. We quantified effective length for a large cohort of DM1 individuals and showed that effective length better predicts age of onset than inherited repeat length, thus improving the genotype-phenotype correlation. Under the extended model, we removed some of the bias in mutation rates making them less length-dependent.

We could specify the role of ATG7 as a genetic modifier for HD particularly in the Italian population.

These findings are consistent with the HD mutation affecting structural aspects of the amino-terminal region of the protein, and support the concept that modulating mutant HTT conformation might provide novel therapeutic and diagnostic opportunities.

Having reached the twentieth anniversary of the discovery of the \"genetic stutter\" which causes HD, we still lack sophisticated insight into why so many HD patients exhibit affective disorders such as depression at very early stages, prior to overt appearance of motor deficits. In this review, we will focus on depression as the major psychiatric manifestation of HD, discuss potential mechanisms of pathogenesis identified from animal models, and compare depression in HD patients with that of the wider gene-negative population. The discovery of depressive-like behaviors as well as cellular and molecular correlates of depression in transgenic HD mice has added strong support to the hypothesis that the HD mutation adds significantly to the genetic load for depression. A key question is whether HD-associated depression differs from that in the general population. Whilst preclinical studies, clinical data, and treatment responses suggest striking similarities, there are also some apparent differences. We discuss various molecular and cellular mechanisms which may contribute to depression in HD, and whether they may generalize to other depressive disorders. The autosomal dominant nature of HD and the existence of models with excellent construct validity provide a unique opportunity to understand the pathogenesis of depression and associated gene-environment interactions. Thus, understanding the pathogenesis of depression in HD may not only facilitate tailored therapeutic approaches for HD sufferers, but may also translate to the clinical depression which devastates the lives of so many people.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:28698602" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:23847583" }, { - "id": "pmid:28642124", + "id": "pmid:23765727", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/28642124", - "title": "Identification of genetic variants associated with Huntington's disease progression: a genome-wide association study.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/23765727", + "title": "Allele-specific expression of the serotonin transporter and its transcription factors following lamotrigine treatment in vitro.", "type": "article-journal", - "doi": "10.1016/s1474-4422(17)30161-8", + "doi": "10.1002/ajmg.b.32178", "authors": [ - ["Davina J Hensman", "Moss"], - ["Antonio F", "Pardi\u00f1as"], - ["Douglas", "Langbehn"], - ["Kitty", "Lo"], - ["Blair R", "Leavitt"], - ["Raymund", "Roos"], - ["Alexandra", "Durr"], - ["Simon", "Mead"], - ["Peter", "Holmans"], - ["Lesley", "Jones"], - ["Sarah J", "Tabrizi"] + ["Ursula M", "D'Souza"], + ["Georgia", "Powell-Smith"], + ["Kate", "Haddley"], + ["Timothy R", "Powell"], + ["Vivien J", "Bubb"], + ["Tom", "Price"], + ["Peter", "McGuffin"], + ["John P", "Quinn"], + ["Anne E", "Farmer"] ], - "publisher": "The Lancet.

Therefore, counteracting mutant huntingtin (mHtt)-induced oxidative stress and mitochondrial dysfunction appears as a new approach to treat this devastating disease. Interestingly, mild mitochondrial uncoupling improves neuronal resistance to stress and facilitates neuronal survival. Mild mitochondrial uncoupling can be induced by the proper dose of 2,4-dinitrophenol (DNP), a proton ionophore that was previously used for weight loss. In this study, we evaluated the effects of chronic administration of DNP at three doses (0.5, 1, 5mg/kg/day) on mHtt-induced behavioral deficits and cellular abnormalities in the N171-82Q HD mouse model. DNP at a low dose (1mg/kg/day) significantly improved motor function and preserved medium spiny neuronal marker DARPP32 and postsynaptic protein PSD95 in the striatum of HD mice. Further mechanistic study suggests that DNP at this dose reduced oxidative stress in HD mice, which was indicated by reduced levels of F2-isoprostanes in the brain of HD mice treated with DNP.

A central challenge to defining the functional consequences of this single polymorphism is the difficulty of distinguishing its subtle effects from the multitude of other sources of biological variation. We demonstrate that an analytical approach based upon continuous correlation with CAG size was able to capture the modest (\u223c21%) contribution of the repeat to the variation in genome-wide gene expression in 107 lymphoblastoid cell lines, with alleles ranging from 15 to 92 CAGs.

Utilizing the Affymetrix platform we performed a genome-wide RNA expression analysis in two BACHD transgenic rat lines (TG5 and TG9) at 12 months of age, both of which carry full-length human mHTT but with different expression levels. By defining the threshold of significance at p\u00a0<\u00a00.01, we found 1608 genes and 871 genes differentially expressed in both TG5 and TG9 rats when compared to the wild type littermates, respectively.

Comparing gene expression profiles of human HD brains and BACHD rats revealed a high concordance in both functional and IPA (Ingenuity Pathway Analysis) canonical pathways relevant to HD. In addition, we investigated the causes leading to gene expression changes at molecular and protein levels in BACHD rats including the involvement of polyQ-containing transcription factors TATA box-binding protein (TBP), Sp1 and CBP as well as the chromatin structure.

Such an enhanced inflammatory response in the brain was not observed in N171- 82Q mice that express mHTT only in neurons, but not in glial cells. Thus, HD glia might play an important role in chronic inflammation that accelerates disease progression in HD mice. Intriguingly, enhanced activation of nuclear factor (NF)-\u03baB-p65 (p65), a transcriptional mediator of inflammatory responses, was observed in astrocytes of patients and mice with HD. Results obtained using primary R6/2 astrocytes suggest that these cells exhibited higher I\u03baB kinase (IKK) activity that caused prolongation of NF-\u03baB activation, thus upregulating proinflammatory factors during inflammation. R6/2 astrocytes also produced a more-damaging effect on primary R6/2 neurons than did WT astrocytes during inflammation. Blockage of IKK reduced the neuronal toxicity caused by R6/2 astrocytes and ameliorated several HD symptoms of R6/2 mice (e.g. decreased neuronal density, impaired motor coordination and poor cognitive function).

TNRs have been studied using both oligonucleotides and plasmids; however, less is know about how repetitive DNA responds to genomic packaging. Here, we investigate the behavior of CAG/CTG repeats incorporated into nucleosome core particles, the most basic unit of chromatin packaging. To assess the general interaction between CAG/CTG repeats and the histone core, we determined the efficiency with which various TNR-containing DNA substrates form nucleosomes, revealing that even short CAG/CTG tracts are robust incorporators. However, the presence of the Huntington gene flanking sequence (htt) decreases the rate of incorporation. Enzymatic and chemical probing revealed repositioning of the DNA in the nucleosome as the number of CAG/CTG repeats increased, regardless of the flanking sequence. Notably, the periodicity of the repeat tract remained unchanged as a function of length and is consistently 10.7 bp per helical turn. In contrast, the periodicity of the nonrepetitive flanking sequence varies and is smaller than the repeat tract at ~10.0-10.5 bp per turn.

In 243 participants (96 premanifest and 35 manifest HD; 112 controls), sensory-motor structural MRI, tractography, resting-state fMRI, electrophysiology (including SEP amplitudes), motor score ratings, and grip force as sensory-motor performance were measured. Following individual modality analyses, we used principal component analysis (PCA) to identify patterns associated with sensory-motor performance, and manifest versus premanifest HD discrimination. We did not detect longitudinal differences over 12 months. PCA showed a pattern of loss of caudate, grey and white matter volume, cortical thickness in premotor and sensory cortex, and disturbed diffusivity in sensory-motor white matter tracts that was connected to CAG repeat length. Two further major principal components appeared in controls and HD individuals indicating that they represent natural biological variation unconnected to the HD mutation. One of these components did not influence HD while the other non-CAG-driven component of axial versus radial diffusivity contrast in white matter tracts were associated with sensory-motor performance and manifest HD. The first component reflects the expected CAG expansion effects on HD pathogenesis. One non-CAG-driven component reveals an independent influence on pathogenesis of biological variation in white matter tracts and merits further investigation to delineate the underlying mechanism and the potential it offers for disease modification.

Allele-specific strategies that preserve expression from the wild-type allele and reduce the levels of mutant protein would be of particular interest. Here, we have conducted proof-of-concept studies to demonstrate that spliceosome-mediated trans-splicing is a viable molecular strategy to specifically repair the HTT allele.

We detected the presence of the trans-spliced RNA in which PTM exon 1 was correctly joined to minigene exons 2 and 3. Furthermore, exon 1 from the PTM was trans-spliced to the endogenous HTT pre-mRNA in cultured cells as well as disease-relevant models, including HD patient fibroblasts and primary neurons from a previously described HD mouse model.

We have analyzed the kinetics of excision of a ubiquitously found oxidized purine base, 8-oxoguanine (oxoG), by DNA glycosylase OGG1 from the substrates containing a CAG run flanked by AT-rich sequences. The values of k(2) rate constant for the removal of oxoG from triplets in the middle of the run were higher than for oxoG at the flanks of the run. The value of k(3) rate constant dropped starting from the third CAG-triplet in the run and remained stable until the 3'-terminal triplet, where it decreased even more. In nuclear extracts, the profile of oxoG removal rate along the run resembled the profile of k(2) constant, suggesting that the reaction rate in the extracts is limited by base excision. The fully reconstituted BER was efficient with all substrates unless oxoG was near the 3'-flank of the run, interfering with the initiation of the repair.

Although there is general agreement that HTT toxicity resides primarily in N-terminal fragments such as the HTT exon1 protein, there is no consensus on the nature of the physical states of HTT exon1 that are induced by polyQ expansion, nor on which of these states might be responsible for toxicity. One hypothesis is that polyQ expansion induces an alternative, toxic conformation in the HTT exon1 monomer. Alternative hypotheses posit that the toxic species is one of several possible aggregated states. Defining the nature of the toxic species is particularly challenging because of facile interconversion between physical states as well as challenges to identifying these states, especially in vivo. Here we describe the use of fluorescence correlation spectroscopy (FCS) to characterize the detailed time and repeat length dependent self-association of HTT exon1-like fragments both with chemically synthesized peptides in vitro and with cell-produced proteins in extracts and in living cells. We find that, in vitro, mutant HTT exon1 peptides engage in polyQ repeat length dependent dimer and tetramer formation, followed by time dependent formation of diffusible spherical and fibrillar oligomers and finally by larger, sedimentable amyloid fibrils. For expanded polyQ HTT exon1 expressed in PC12 cells, monomers are absent, with tetramers being the smallest molecular form detected, followed in the incubation time course by small, diffusible aggregates at 6-9 hours and larger, sedimentable aggregates that begin to build up at 12 hrs. In these cell cultures, significant nuclear DNA damage appears by 6 hours, followed at later times by caspase 3 induction, mitochondrial dysfunction, and cell death. Our data thus defines limits on the sizes and concentrations of different physical states of HTT exon1 along the reaction profile in the context of emerging cellular distress.

Studies in glutamatergic cells indicate that synaptic NMDAR transmission increases phosphorylated cyclic-AMP response element binding protein (pCREB) levels and drives neuroprotective gene transcription, whereas extrasynaptic NMDAR activation reduces pCREB and promotes cell death. By generating striatal and cortical neuronal co-cultures to investigate the glutamatergic innervation of striatal neurons, we demonstrate that dichotomous synaptic and extrasynaptic NMDAR signaling also occurs in GABAergic striatal medium-sized spiny neurons (MSNs), which are acutely vulnerable in HD. Further, we show that wild-type (WT) and HD transgenic YAC128 MSNs co-cultured with cortical cells have similar levels of glutamatergic synapses, synaptic NMDAR currents and synaptic GluN2B and GluN2A subunit-containing NMDARs. However, NMDAR whole-cell, and especially extrasynaptic, current is elevated in YAC128 MSNs. Moreover, GluN2B subunit-containing NMDAR surface expression is markedly increased, irrespective of whether or not the co-cultured cortical cells express mutant huntingtin. The data suggest that MSN cell-autonomous increases in extrasynaptic NMDARs are driven by the HD mutation. Consistent with these results, we find that extrasynaptic NMDAR-induced pCREB reductions and apoptosis are also augmented in YAC128 MSNs. Moreover, both NMDAR-mediated apoptosis and CREB-off signaling are blocked by co-application of either memantine or the GluN2B subunit-selective antagonist ifenprodil in YAC128 MSNs.

BRCA1 specifically interacted with \u03b3-H2AX via the BRCT domain, and this association was reduced in HD. BRCA1 overexpression restored \u03b3-H2AX level in the nucleus of HD cells, while BRCA1 knockdown reduced the spatiotemporal propagation of \u03b3-H2AX foci to the nucleoplasm. The deregulation of BRCA1 correlated with an abnormal nuclear distribution of \u03b3-H2AX in striatal neurons of HD transgenic (R6/2) mice and BRCA1(+/-) mice.

Huntingtin-induced toxicity is believed to be mediated by a conformational change in expanded huntingtin, leading to protein misfolding and aggregation, aberrant protein interactions and neuronal cell death. While many non-systematic studies of huntingtin interactions have been reported, they were not designed to identify and quantify the changes in the huntingtin interactome induced by polyglutamine expansion. We used tandem affinity purification and quantitative proteomics to compare and quantify interactions of normal or expanded huntingtin isolated from a striatal cell line. We found that proteins preferentially interacting with expanded huntingtin are enriched for intrinsically disordered proteins, consistent with previously suggested roles of such proteins in neurodegenerative disorders. Our functional analysis indicates that proteins related to energy production, protein trafficking, RNA post-transcriptional modifications and cell death were significantly enriched among preferential interactors of expanded huntingtin. Expanded huntingtin interacted with many mitochondrial proteins, including AIFM1, consistent with a role for mitochondrial dysfunction in HD. Furthermore, expanded huntingtin interacted with the stress granule-associated proteins Caprin-1 and G3BP and redistributed to RNA stress granules under ER-stress conditions.

In human neuronal cells, expanded HTT exon-1 mRNA with CAG repeat lengths above the threshold for complete penetrance (40 or greater) induced cell death and increased levels of small CAG-repeated RNAs (sCAGs), of \u224821 nucleotides in a Dicer-dependent manner.

Luciferase-reporter assays showed that expanded HTT silences the expression of CTG-containing genes that are down-regulated in HD.

Synaptic N-methyl-D-aspartate receptor (NMDAR) current was similar, but extrasynaptic current, associated with cell death signaling, was enhanced in YAC128 SPN in T-S coculture. Employing optical stimulation of cortical versus thalamic afferents and recording from striatal SPN in brain slice, we found increased glutamate release probability and reduced AMPAR/NMDAR current ratios in thalamostriatal synapses, most prominently in YAC128. Enhanced extrasynaptic NMDAR current in YAC128 SPN was apparent with both cortical and thalamic stimulation.

This procedure provides a simple means to assess this type of phenotype in rodents, with issues in consummatory vs. incentive motivation reflected in general alterations in fixed- versus progressive alterations on an escalating-ratio schedules respectively, providing translational measures of the amotivation/apathy construct of the human realm to the homologous construct of incentive motivation in preclinical models of human disease.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:26375764" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:23925262" }, { - "id": "pmid:26247199", + "id": "pmid:23476655", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/26247199", - "title": "Suppression of Somatic Expansion Delays the Onset of Pathophysiology in a Mouse Model of Huntington's Disease.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/23476655", + "title": "Predicting Disease Onset from Mutation Status Using Proband and Relative Data with Applications to Huntington's Disease.", "type": "article-journal", - "doi": "10.1371/journal.pgen.1005267", + "doi": "10.1155/2012/375935", "authors": [ - ["Helen", "Budworth"], - ["Faye R", "Harris"], - ["Paul", "Williams"], - ["Do Yup", "Lee"], - ["Amy", "Holt"], - ["Jens", "Pahnke"], - ["Bartosz", "Szczesny"], - ["Karina", "Acevedo-Torres"], - ["Sylvette", "Ayala-Pe\u00f1a"], - ["Cynthia T", "McMurray"] + ["Tianle", "Chen"], + ["Yuanjia", "Wang"], + ["Yanyuan", "Ma"], + ["Karen", "Marder"], + ["Douglas R", "Langbehn"] ], - "publisher": "PLoS genetics", - "issn": "1553-7404", - "date": "2015-08-06", - "abstract": "Huntington's Disease (HD) is caused by inheritance of a single disease-length allele harboring an expanded CAG repeat, which continues to expand in somatic tissues with age.

To explore possible functional similarity between HTT and Atg11, we investigated whether the C-terminal domain of HTT interacts with mammalian counterparts of yeast Atg11-interacting proteins. Strikingly, this domain of HTT coimmunoprecipitates with several key Atg11 interactors, including the Atg1/Unc-51-like autophagy activating kinase 1 kinase complex, autophagic receptor proteins, and mammalian Atg8 homologs. Mutation of a phylogenetically conserved WXXL domain in a C-terminal HTT fragment reduces coprecipitation with mammalian Atg8 homolog GABARAPL1, suggesting a direct interaction.

Therefore we investigated the impact of a robust stressor (i.e. restraint) on the onset and progression of a range of behavioral phenotypes in R6/1 transgenic HD mice. Restraint was administered for 1h daily from 6weeks of age and continued until R6/1 mice were clearly motor symptomatic at 14weeks of age.

Motor coordination and locomotor activity were enhanced by chronic restraint in males, regardless of genotype. However, there was no effect of restraint on motor performances in female animals. At 8weeks of age, olfactory sensitivity was impaired by restraint in R6/1 HD female mice, but not in WT mice. In male R6/1 mice, the olfactory deficit was exacerbated by restraint and olfaction was also impaired in male WT mice. The development of deficits in saccharin preference, Y-maze memory, nest-building and sexually-motivated vocalizations was unaffected by chronic restraint in R6/1 and had little impact on such behavioral performances in WT animals.

In HD patient-derived fibroblasts with expanded alleles containing 44, 77 or 109 CAG repeats, HTTex1a and HTTex1b were effective in suppressing the expression of mutant and non-mutant transcripts.

Therefore, better understanding of environmental modifiers may uncover potential therapeutic approaches to delay disease onset and progression. Recent data suggest that HD patients and transgenic mouse models show a dysregulated stress response. In this present study, we elevated stress hormone levels through oral corticosterone (CORT) treatment and assessed its impact on the development of motor impairment and cognitive deficits using the R6/1 transgenic mouse model of HD. We found that CORT consumption did not alter rotarod performance of R6/1 HD or wild-type (WT) littermates. However, the onset of hippocampal-dependent Y-maze deficits was accelerated in male R6/1 mice by 5days of CORT treatment, whereas short term memory of WT and female R6/1 mice was unaffected. We then further investigated the male HD susceptibility to CORT by measuring TrkB activation, BDNF and glucocorticoid receptor expression as well as the level of cell proliferation in the hippocampus. CORT treatment increased the levels of phosphorylated TrkB in male R6/1 mice only. There were no effects of CORT on hippocampal BDNF protein or mRNA levels; nor on expression of the glucocorticoid receptors in any group. Hippocampal cell proliferation was decreased in male R6/1 mice and this was further reduced in CORT-drinking male R6/1 mice. Female mice (WT and R6/1) appeared to be protected from the impacts of CORT treatment in all our hippocampal measures. Overall, our data demonstrate that treatment with corticosterone is able to modulate the onset of HD symptomatology. We present the first evidence of a male-specific vulnerability to stress impacting on the development of short-term memory deficits in HD. More generally, we found that female mice were protected from the detrimental effects of CORT treatment on a variety of hippocampus-based measures.

Instability affects both germline and somatic cells. Somatic instability increases with age and is tissue-specific. In particular, the CAG repeat sequence in the striatum, the brain region that preferentially degenerates in HD, is highly unstable, whereas it is rather stable in the disease-spared cerebellum. The mechanisms underlying the age-dependence and tissue-specificity of somatic CAG instability remain obscure. Recent studies have suggested that DNA oxidation and OGG1, a glycosylase involved in the repair of 8-oxoguanine lesions, contribute to this process. We show that in HD mice oxidative DNA damage abnormally accumulates at CAG repeats in a length-dependent, but age- and tissue-independent manner, indicating that oxidative DNA damage alone is not sufficient to trigger somatic instability. Protein levels and activities of major base excision repair (BER) enzymes were compared between striatum and cerebellum of HD mice. Strikingly, 5'-flap endonuclease activity was much lower in the striatum than in the cerebellum of HD mice. Accordingly, Flap Endonuclease-1 (FEN1), the main enzyme responsible for 5'-flap endonuclease activity, and the BER cofactor HMGB1, both of which participate in long-patch BER (LP-BER), were also significantly lower in the striatum compared to the cerebellum. Finally, chromatin immunoprecipitation experiments revealed that POLbeta was specifically enriched at CAG expansions in the striatum, but not in the cerebellum of HD mice. These in vivo data fit a model in which POLbeta strand displacement activity during LP-BER promotes the formation of stable 5'-flap structures at CAG repeats representing pre-expanded intermediate structures, which are not efficiently removed when FEN1 activity is constitutively low.

The mechanistic basis for such selective neuronal vulnerability remains unclear. A necessary step toward resolving this enigma is to define the cell types in which mHTT expression is causally linked to the disease pathogenesis. Using a conditional transgenic mouse model of HD, in which the mice express full-length human mHTT from a bacterial artificial chromosome transgene (BACHD), we genetically reduced mHTT expression in neuronal populations in the striatum, cortex or both. We show that reduction of cortical mHTT expression in BACHD mice partially improves motor and psychiatric-like behavioral deficits but does not improve neurodegeneration, whereas reduction of mHTT expression in both neuronal populations consistently ameliorates all behavioral deficits and selective brain atrophy in this HD model. Furthermore, whereas reduction of mHTT expression in cortical or striatal neurons partially ameliorates corticostriatal synaptic deficits, further restoration of striatal synaptic function can be achieved by reduction of mHTT expression in both neuronal cell types.

A 33-year old woman presenting with an HD like phenotype with a de novo 54 CAG/CAA repeat expansion was identified. Her normal allele included 38 repeats. The patient's mother and father both carried normal range repeats, 38/38 and 33/39 respectively. Analysis of the repeat structures revealed that the expansion had occurred upon expansion of the longer paternal allele. We conclude that, however rare, SCA17 must be considered as a cause of Huntington's disease-like phenotypes and ataxia syndromes, also in isolated cases.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:24452335" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:19595623" }, { - "id": "pmid:24390280", + "id": "pmid:21048629", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/24390280", - "title": "Intrajugular vein delivery of AAV9-RNAi prevents neuropathological changes and weight loss in Huntington's disease mice.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/21048629", + "title": "A survey of (CAG)n repeats causing juvenile Huntington disease in an Iranian family with 4 affected members.", "type": "article-journal", - "doi": "10.1038/mt.2013.289", + "doi": "", "authors": [ - ["Brett D", "Dufour"], - ["Catherine A", "Smith"], - ["Randall L", "Clark"], - ["Timothy R", "Walker"], - ["Jodi L", "McBride"] + ["Mehrdokht", "Mazdeh"], + ["Hamid", "Pour-Jafari"], + ["Ali", "Ghaleiha"], + ["Bita", "Pour-Jafari"] ], - "publisher": "Molecular therapy : the journal of the American Society of Gene Therapy", - "issn": "1525-0024", - "date": "2014-01-06", - "abstract": "Huntington's disease (HD) is a fatal neurological disorder caused by a CAG repeat expansion in the HTT gene, which encodes a mutant huntingtin protein (mHTT).

Therefore, we have embarked on a series of genetic studies to uncover the HDAC target that is relevant to therapeutic development for HD. HDAC7 is of interest in this context because SAHA has been shown to decrease HDAC7 expression in cell culture systems in addition to inhibiting enzyme activity. After confirming that expression levels of Hdac7 are decreased in the brains of wild type and R6/2 mice after SAHA administration, we performed a genetic cross to determine whether genetic reduction of Hdac7 would alleviate phenotypes in the R6/2 mice. We found no improvement in a number of physiological or behavioral phenotypes. Similarly, the dysregulated expression levels of a number of genes of interest were not improved suggesting that reduction in Hdac7 does not alleviate the R6/2 HD-related transcriptional dysregulation.

These sequences mutate by changing the number of repeats not just between generations, but also during the lifetime of affected individuals. Levels of somatic instability contribute to disease onset and progression but as changes are tissue-specific, age- and repeat length-dependent, interpretation of the level of somatic instability in an individual is confounded by these considerations. Mathematical models, fitted to CTG repeat length distributions derived from blood DNA, from a large cohort of DM1-affected or at risk individuals, have recently been used to quantify inherited repeat lengths and mutation rates. Taking into account age, the estimated mutation rates are lower than predicted among individuals with small alleles (inherited repeat lengths less than 100 CTGs), suggesting that these rates may be suppressed at the lower end of the disease-causing range. In this study, we propose that a length-specific effect operates within this range and tested this hypothesis using a model comparison approach. To calibrate the extended model, we used data derived from blood DNA from DM1 individuals and, for the first time, buccal DNA from HD individuals. In a novel application of this extended model, we identified individuals whose effective repeat length, with regards to somatic instability, is less than their actual repeat length. A plausible explanation for this distinction is that the expanded repeat tract is compromised by interruptions or other unusual features. We quantified effective length for a large cohort of DM1 individuals and showed that effective length better predicts age of onset than inherited repeat length, thus improving the genotype-phenotype correlation. Under the extended model, we removed some of the bias in mutation rates making them less length-dependent.

However, loss of normal huntingtin function resulting from the polyglutamine expansion might also contribute to the pathogenesis of HD. Here, we have studied the effects of huntingtin knockdown in zebrafish using morpholino antisense oligonucleotides, as its huntingtin orthologue has 70% amino acid identity with the human protein. Reduced huntingtin levels did not impact on gastrulation and early development, but caused massive apoptosis of neuronal cells by 24 hpf.

Older huntingtin knockdown fish developed lower jaw abnormalities with most branchial arches missing. Molecular analysis revealed that BDNF expression was reduced by approximately 50%. Reduction of BDNF levels by injection of a BDNF morpholino resulted in phenotypes very similar to those seen in huntingtin knockdown zebrafish. The phenotypes of both huntingtin- and BDNF-knockdown zebrafish showed significant rescue when treated with exogenous BDNF protein.

The number of CAG repeats in the HD gene is the main predictor of disease-onset, but the remaining variation is strongly heritable. Transcriptional dysregulation, mitochondrial dysfunction and enhanced oxidative stress have been implicated in the pathogenesis. Recent studies suggest that PGC-1alpha, a transcriptional master regulator of mitochondrial biogenesis and metabolism, is defective in HD. A genome wide search for modifier genes of HD age-of-onset had suggested linkage at chromosomal region 4p16-4p15, near the locus of PPARGC1A, the gene coding for PGC-1alpha.

Having reached the twentieth anniversary of the discovery of the \"genetic stutter\" which causes HD, we still lack sophisticated insight into why so many HD patients exhibit affective disorders such as depression at very early stages, prior to overt appearance of motor deficits. In this review, we will focus on depression as the major psychiatric manifestation of HD, discuss potential mechanisms of pathogenesis identified from animal models, and compare depression in HD patients with that of the wider gene-negative population. The discovery of depressive-like behaviors as well as cellular and molecular correlates of depression in transgenic HD mice has added strong support to the hypothesis that the HD mutation adds significantly to the genetic load for depression. A key question is whether HD-associated depression differs from that in the general population. Whilst preclinical studies, clinical data, and treatment responses suggest striking similarities, there are also some apparent differences. We discuss various molecular and cellular mechanisms which may contribute to depression in HD, and whether they may generalize to other depressive disorders. The autosomal dominant nature of HD and the existence of models with excellent construct validity provide a unique opportunity to understand the pathogenesis of depression and associated gene-environment interactions.

Whole-cell patch clamp recordings were performed on layer 2/3 primary motor cortical pyramidal cells and parvalbumin interneurons from BACHD mice at 3 months, when the mice begin to demonstrate mild motor dysfunction, and at 6 months, when the motor dysfunction is more severe. Changes in synaptic variances were detectable at 3 months, and at 6 months BACHD mice display progressive synaptic pathology in the form of reduced cortical excitation and loss of inhibition onto pyramidal cells.

There are conflicting reports about the relationship between CAGn and clinical progression of HD. We conducted an analysis of data from the Coenzyme Q10 and Remacemide Evaluation in Huntington's Disease (CARE-HD) clinical trial. We modeled progression over 30 months on the Unified Huntington's Disease Rating Scale (UHDRS) and supplemental neuropsychological and behavioral tests using multiple linear regression. Mean subject age was 47.9 +/- 10.5 years and mean CAGn was 45.0 +/- 4.1. Multiple linear regression revealed statistically significant associations between CAGn and worsening on several motor, cognitive, and functional outcomes, but not behavioral outcomes. Many effects were clinically important; 10 additional CAG repeats were associated with an 81% increase in progression on the Independence Scale.

The molecular trigger of HD is a polyglutamine expansion in the Huntingtin protein (Htt). The mutant Htt protein forms insoluble nuclear aggregates which have been proposed to play a key role in causing neuronal cell death in HD. Other lines of investigation suggest that expression of mutant Htt facilitates activity of the NR2B subtype of NMDA receptors and the type 1 inositol 1,4,5-trisphosphate receptors (InsP(3)R1), and that disturbed calcium (Ca(2+)) signaling causes apoptosis of MSNs in HD. The YAC128 transgenic HD mouse model expresses the full-length human Htt protein with 120Q CAG repeat expansion and displays an age-dependent loss of striatal neurons as seen in human HD brain. In contrast, the shortstop mice express an amino-terminal fragment of the mutant Htt protein (exons 1 and 2) and display no behavioral abnormalities or striatal neurodegeneration despite widespread formation of neuronal inclusions. Here we compared Ca(2+) signals in primary MSN neuronal cultures derived from YAC128 and shortstop mice to their wild-type non-transgenic littermates. Repetitive application of glutamate results in supranormal Ca(2+) responses in YAC128 MSNs, but not in shortstop MSNs. In addition, while currents mediated by the NR2B subtype of NMDA receptors were increased in YAC128 MSNs, currents in SS MSNs were found to be similar to WT. Furthermore, YAC128 MSNs were sensitized to glutamate-induced apoptosis. Consistent with these findings, we found that application of glutamate induced rapid loss of mitochondrial membrane potential in YAC128 MSNs. In contrast, SS MSNs do not show increased cell death postglutamate treatment nor accelerated loss of mitochondrial membrane potential following glutamate stimulation. Glutamate-induced loss of mitochondrial membrane potential in YAC128 MSNs could be prevented by inhibitors of NR2B NMDA receptors and mGluR1/5 receptors. Our results are consistent with the hypothesis that disturbed neuronal Ca(2+) signaling plays a significant role in the degeneration of MSN containing full-length mutant Htt(exp).

To assess the general interaction between CAG/CTG repeats and the histone core, we determined the efficiency with which various TNR-containing DNA substrates form nucleosomes, revealing that even short CAG/CTG tracts are robust incorporators. However, the presence of the Huntington gene flanking sequence (htt) decreases the rate of incorporation. Enzymatic and chemical probing revealed repositioning of the DNA in the nucleosome as the number of CAG/CTG repeats increased, regardless of the flanking sequence. Notably, the periodicity of the repeat tract remained unchanged as a function of length and is consistently 10.7 bp per helical turn. In contrast, the periodicity of the nonrepetitive flanking sequence varies and is smaller than the repeat tract at ~10.0-10.5 bp per turn. Furthermore, while the CAG/CTG repeats remain as a canonical duplex in the nucleosome, nucleosome formation causes kinking in a secondary repeat tract in the htt gene, comprised of CCG/CGG repeats.

In this regard, the YAC128 mouse model, expressing full-length human huntingtin with 128 glutamine repeats, has been the focus of much interest. Although NMDA-induced apoptosis is enhanced in YAC128 MSNs, here we report that the initial steps in the death signaling pathway, including NMDA receptor (NMDAR) current and cytosolic Ca2+ loading, are similar to those observed in wild-type MSNs. In contrast, we found that the NMDAR-mediated Ca2+ load triggered a strikingly enhanced loss of mitochondrial membrane potential in YAC128 MSNs, suggesting that NMDAR signaling via the mitochondrial apoptotic pathway is altered. This effect was accompanied by impaired cytosolic Ca2+ clearance after removal of NMDA, a difference that was not apparent after high potassium-evoked depolarization-mediated Ca2+ entry. Inhibition of the mitochondrial permeability transition (mPT) reduced peak cytosolic Ca2+ and mitochondrial depolarization evoked by NMDA in YAC128 MSNs but not wild-type MSNs. Hence, in contrast to YAC models with moderate CAG expansions, the enhanced NMDA-induced apoptosis in YAC128 MSNs is predominantly determined by augmented mitochondrial sensitivity to Ca2+-induced activation of the mPT.

Studies in glutamatergic cells indicate that synaptic NMDAR transmission increases phosphorylated cyclic-AMP response element binding protein (pCREB) levels and drives neuroprotective gene transcription, whereas extrasynaptic NMDAR activation reduces pCREB and promotes cell death. By generating striatal and cortical neuronal co-cultures to investigate the glutamatergic innervation of striatal neurons, we demonstrate that dichotomous synaptic and extrasynaptic NMDAR signaling also occurs in GABAergic striatal medium-sized spiny neurons (MSNs), which are acutely vulnerable in HD. Further, we show that wild-type (WT) and HD transgenic YAC128 MSNs co-cultured with cortical cells have similar levels of glutamatergic synapses, synaptic NMDAR currents and synaptic GluN2B and GluN2A subunit-containing NMDARs. However, NMDAR whole-cell, and especially extrasynaptic, current is elevated in YAC128 MSNs. Moreover, GluN2B subunit-containing NMDAR surface expression is markedly increased, irrespective of whether or not the co-cultured cortical cells express mutant huntingtin. The data suggest that MSN cell-autonomous increases in extrasynaptic NMDARs are driven by the HD mutation. Consistent with these results, we find that extrasynaptic NMDAR-induced pCREB reductions and apoptosis are also augmented in YAC128 MSNs. Moreover, both NMDAR-mediated apoptosis and CREB-off signaling are blocked by co-application of either memantine or the GluN2B subunit-selective antagonist ifenprodil in YAC128 MSNs. GluN2A-subunit-selective concentrations of the antagonist NVP-AAM077 did not reduce cell death in either genotype. Cortico-striatal co-cultures provide an in vitro model system in which to better investigate striatal neuronal dysfunction in disease than mono-cultured striatal cells.

These changes were coupled to a disruption of circadian rhythm.

In human neuronal cells, expanded HTT exon-1 mRNA with CAG repeat lengths above the threshold for complete penetrance (40 or greater) induced cell death and increased levels of small CAG-repeated RNAs (sCAGs), of \u224821 nucleotides in a Dicer-dependent manner.

Flap endonuclease 1 (Fen1), has an endonuclease activity specific for 5' flap structures and is involved in Okazaki fragment processing and base excision repair. Fen1 also plays an important role in preventing instability of CAG/CTG trinucleotide repeat sequences, as the expansion frequency of CAG/CTG repeats is increased in FEN1 mutants in vitro and in yeast cells defective for the yeast homolog, RAD27. Here we have tested whether one copy of yeast FEN1 is enough to maintain CAG/CTG tract stability in diploid yeast cells. We found that CAG/CTG repeats are stable in RAD27 +/- cells if the tract is 70 repeats long and exhibit a slightly increased expansion frequency if the tract is 85 or 130 repeats long. However for CAG-155 tracts, the repeat expansion frequency in RAD27 +/- cells is significantly higher than in RAD27 +/+ cells. This data indicates that cells containing longer CAG/CTG repeats need more Fen1 protein to maintain tract stability and that maintenance of long CAG/CTG repeats is particularly sensitive to Fen1 levels.

In 278 normal subjects, we determined CAG repeat length within the IT15 gene on chromosome 4 and analyzed high-resolution T1-weighted magnetic resonance images by the use of voxel-based morphometry. We found an increase of GM with increasing long CAG repeat and its interaction with age within the pallidum, which is involved in Huntington's disease. Our study demonstrates that a certain trinucleotide repeat influences normal brain structure in humans.

The best characterized putative cleavage event is at amino acid 586, hypothesized to be mediated by caspase 6. A corollary of the caspase 6 cleavage hypothesis is that the caspase 6 fragment should be a toxic fragment. To test this hypothesis, and further characterize the role of this fragment, we have generated transgenic mice expressing the N-terminal 586 aa of Htt with a polyglutamine repeat length of 82 (N586-82Q), under the control of the prion promoter. N586-82Q mice show a clear progressive rotarod deficit by 4 months of age, and are hyperactive starting at 5 months, later changing to hypoactivity before early mortality. MRI studies reveal widespread brain atrophy, and histologic studies demonstrate an abundance of Htt aggregates, mostly cytoplasmic, which are predominantly composed of the N586-82Q polypeptide. Smaller soluble N-terminal fragments appear to accumulate over time, peaking at 4 months, and are predominantly found in the nuclear fraction. This model appears to have a phenotype more severe than current full-length Htt models, but less severe than HD mouse models expressing shorter Htt fragments.

Brain-specific knockout of Sirt1 results in exacerbation of brain pathology in a mouse model of Huntington's disease, whereas overexpression of Sirt1 improves survival, neuropathology and the expression of brain-derived neurotrophic factor (BDNF) in Huntington's disease mice. We show that Sirt1 deacetylase activity directly targets neurons to mediate neuroprotection from mutant HTT. The neuroprotective effect of Sirt1 requires the presence of CREB-regulated transcription coactivator 1 (TORC1), a brain-specific modulator of CREB activity. We show that under normal conditions, Sirt1 deacetylates and activates TORC1 by promoting its dephosphorylation and its interaction with CREB. We identified BDNF as a key target of Sirt1 and TORC1 transcriptional activity in both normal and Huntington's disease neurons.

Recent studies demonstrate that neuronal dysfunction without cell death also plays an important role in early and mid-stages of the disease. Here, we report that cholinergic transmission is affected in a HD transgenic mouse model (R6/1) and in tissues from HD patients. Stereological analysis shows no loss of cholinergic neurons in the striatum or septum in R6/1 mice. In contrast, the levels of mRNA and protein for vesicular acetylcholine transporter (VAChT) and choline acetyltransferase (ChAT) are decreased in the striatum and cortex, and acetylcholine esterase activity is lowered in the striatum of R6/1 mice already at young ages. Accordingly, VAChT is also reduced in striatal tissue from patients with HD. The decrease of VAChT in the patient samples studied is restricted to the striatum and does not occur in the hippocampus or the spinal cord.

Similar conditions can be induced in animal models by expression of the polyGln sequence alone or in other protein contexts. Besides the polyGln sequence, the cellular context of the disease protein, and the sequence context of the polyGln within the disease protein, are both likely to contribute to polyGln physical behavior and to pathology. In HD, the N-terminal, exon-1 segment of the protein huntingtin contains the polyGln sequence immediately followed by an oligoproline region. We show here that introduction of a P10 sequence C-terminal to polyGln in synthetic peptides decreases both the rate of formation and the apparent stability of the amyloid-like aggregates associated with this family of diseases. The sequence can be trimmed to P6 without altering the suppression, but a P3 sequence is ineffective. Spacers up to at least three amino acid residues in length can be inserted between polyGln and P10 without altering this effect. There is no suppression, however, when the P10 sequence is either placed on the N-terminal side of polyGln or attached to polyGln via a side-chain tether. The nucleation mechanism of a Q40 sequence is unchanged upon addition of a P10 C-terminal extension, yielding a critical nucleus of one. The effects of oligoPro length and structural context on polyGln aggregation are correlated strongly with alterations in the circular dichroism spectra of the monomeric peptides. For example, the P10 sequence eliminates the small amount of alpha helical content otherwise exhibited by the Q40 sequence. The P10 sequence may suppress aggregation by stabilizing an aggregation-incompetent conformation of the monomer.

Quantitative TDT (QTDT) analysis also showed significant association of the intron 2 VNTR 12-repeat allele with rigid-compulsive behavior (P = 0.015).

One of the twins has presented symptoms of HD for 4 years; his skin fibroblasts and hair roots carried only the cell line with the 47 CAG repeat allele. The other twin, who is without symptoms at present, displayed mosaicism in skin fibroblasts and hair roots. If the proportion of the two cell lines in the brain of each twin resembles that of their hair roots (another tissue originating from the ectoderm), the mosaicism in the unaffected twin would mean that only a part of his brain cells carried the expanded allele, which could explain why he, in contrast to his brother, has no symptoms at this time.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:20001119" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:15372528" }, { - "id": "pmid:19997493", + "id": "pmid:15345132", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/19997493", - "title": "Stoichiometry of base excision repair proteins correlates with increased somatic CAG instability in striatum over cerebellum in Huntington's disease transgenic mice.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/15345132", + "title": "In vitro proliferation and expansion of hematopoietic progenitors present in mobilized peripheral blood from normal subjects and cancer patients.", "type": "article-journal", - "doi": "10.1371/journal.pgen.1000749", + "doi": "10.1089/scd.2004.13.382", "authors": [ - ["Agathi-Vassiliki", "Goula"], - ["Brian R", "Berquist"], - ["David M", "Wilson"], - ["Vanessa C", "Wheeler"], - ["Yvon", "Trottier"], - ["Karine", "Merienne"] + ["Guadalupe", "Mart\u00ednez-Jaramillo"], + ["Patricia", "Flores-Guzm\u00e1n"], + ["Juan Jos\u00e9", "Montesinos"], + ["Sandra", "Quintana"], + ["Javier", "Bautista"], + ["Elizabeth", "S\u00e1nchez-Valle"], + ["Mar\u00eda", "de Jes\u00fas Nambo"], + ["Hector", "Mayani"] ], - "publisher": "PLoS genetics", - "issn": "1553-7404", - "date": "2009-12-04", - "abstract": "Huntington's disease (HD) is a progressive neurodegenerative disorder caused by expansion of an unstable CAG repeat in the coding sequence of the Huntingtin (HTT) gene. Instability affects both germline and somatic cells. Somatic instability increases with age and is tissue-specific. In particular, the CAG repeat sequence in the striatum, the brain region that preferentially degenerates in HD, is highly unstable, whereas it is rather stable in the disease-spared cerebellum. The mechanisms underlying the age-dependence and tissue-specificity of somatic CAG instability remain obscure. Recent studies have suggested that DNA oxidation and OGG1, a glycosylase involved in the repair of 8-oxoguanine lesions, contribute to this process. We show that in HD mice oxidative DNA damage abnormally accumulates at CAG repeats in a length-dependent, but age- and tissue-independent manner, indicating that oxidative DNA damage alone is not sufficient to trigger somatic instability. Protein levels and activities of major base excision repair (BER) enzymes were compared between striatum and cerebellum of HD mice. Strikingly, 5'-flap endonuclease activity was much lower in the striatum than in the cerebellum of HD mice. Accordingly, Flap Endonuclease-1 (FEN1), the main enzyme responsible for 5'-flap endonuclease activity, and the BER cofactor HMGB1, both of which participate in long-patch BER (LP-BER), were also significantly lower in the striatum compared to the cerebellum. Finally, chromatin immunoprecipitation experiments revealed that POLbeta was specifically enriched at CAG expansions in the striatum, but not in the cerebellum of HD mice. These in vivo data fit a model in which POLbeta strand displacement activity during LP-BER promotes the formation of stable 5'-flap structures at CAG repeats representing pre-expanded intermediate structures, which are not efficiently removed when FEN1 activity is constitutively low. We propose that the stoichiometry of BER enzymes is one critical factor underlying the tissue selectivity of somatic CAG expansion.", + "publisher": "Stem cells and development", + "issn": "1547-3287", + "date": "2004-08-01", + "abstract": "In the present study, we have assessed, in a comparative manner, the in vitro proliferation and expansion potentials of hematopoietic progenitor cells (HPC) present in mobilized peripheral blood from normal subjects (MPB-n; n = 18) and cancer patients (MPB-c; n = 18). The latter included patients with breast cancer (BrCa; n = 8), Hodgkin disease (HD; n = 4), non-Hodgkin lymphoma (NHL; n = 3), and acute myeloid leukemia (AML; n = 3). Progenitor cells from normal bone marrow (BM) and umbilical cord blood (UCB) were included as controls. HPC, enriched by a negative selection procedure, were cultured for 25 days, in serum-free liquid media in the presence of a cytokine combination including early- and late-acting cytokines. Our results demonstrate that the in vitro biological properties of progenitor cells present in MPB differ, depending on whether they are derived from healthy individuals, from patients with solid tumors, or from patients with hematological neoplasias. Among all cell sources analyzed, UCB-derived progenitors showed the greatest proliferation and expansion potentials (1000-fold increase in total cell numbers on day 15, and a 22-fold increase in myeloid progenitor cell numbers, at day 10). Progenitor cells present in MPB from hematologically normal individuals showed proliferation and expansion potentials comparable to those of HPC from normal BM (500-fold increase in total cell numbers on day 15, and a 14-fold increase in myeloid progenitor cell numbers, at day 10). The proliferation/expansion potentials of MPB progenitors from BrCa patients were also within the normal range, although in the lower levels (327-fold increase in total cell numbers, on day 15, and 11.8-fold increase in myeloid progenitors, at day 10).

Within this context there is a current interest in the understanding of the role played by polymorphisms of DNA repair genes in the inter-individual risk to develop neurodegenerative pathologies, as well as in the onset and the progression of disease symptoms. Particularly, somatic CAG repeat expansion of the gene encoding for huntingtin has been observed in tissues of patients affected by Huntington's disease (HD), including blood and brain. Recent evidence suggests that somatic CAG repeat expansion in HD cells might contribute to disease age at onset and is mediated by the DNA repair OGG1 enzyme, during the removal of 8-oxoguanine (8-oxoG) from the DNA. There is also evidence that the expression of hMTH1, which removes 8-oxoG from the nucleotide pool, protects mice from HD-like symptoms, and progenitor striatal cells from the toxic effects of the mutant huntingtin. The hOGG1 Ser326Cys polymorphism results in reduced OGG1 activity and increased 8-oxoG formation.

Enriching the environment of HD transgenic mice delays the onset of symptoms, so we also examine the effects of enrichment on dendrite pathology. Golgi-impregnated tissue from symptomatic R6/1 HD mice reveals a decrease in dendritic spine density and dendritic spine length in striatal medium spiny neurons and cortical pyramidal neurons. HD also causes a specific reduction in the proportion of bifurcated dendritic spines on basal dendrites of cortical pyramidal neurons. No differences in soma size, recurving distal dendrites, or dendritic branching were observed.

The molecular pathways leading to the selectivity of neuronal cell death in HD are poorly understood. Proteolytic processing of full-length mutant huntingtin (Htt) and subsequent events may play an important role in the selective neuronal cell death found in this disease. Despite the identification of Htt as a substrate for caspases, it is not known which caspase(s) cleaves Htt in vivo or whether regional expression of caspases contribute to selective neuronal cells loss. Here, we evaluate whether specific caspases are involved in cell death induced by mutant Htt and if this correlates with our recent finding that Htt is cleaved in vivo at the caspase consensus site 552. We find that caspase-2 cleaves Htt selectively at amino acid 552. Further, Htt recruits caspase-2 into an apoptosome-like complex. Binding of caspase-2 to Htt is polyglutamine repeat-length dependent, and therefore may serve as a critical initiation step in HD cell death. This hypothesis is supported by the requirement of caspase-2 for the death of mouse primary striatal cells derived from HD transgenic mice expressing full-length Htt (YAC72). Expression of catalytically inactive (dominant-negative) forms of caspase-2, caspase-7, and to some extent caspase-6, reduced the cell death of YAC72 primary striatal cells, while the catalytically inactive forms of caspase-3, -8, and -9 did not. Histological analysis of post-mortem human brain tissue and YAC72 mice revealed activation of caspases and enhanced caspase-2 immunoreactivity in medium spiny neurons of the striatum and the cortical projection neurons when compared to controls. Further, upregulation of caspase-2 correlates directly with decreased levels of brain-derived neurotrophic factor in the cortex and striatum of 3-month YAC72 transgenic mice and therefore suggests that these changes are early events in HD pathogenesis.

After confirming that expression levels of Hdac7 are decreased in the brains of wild type and R6/2 mice after SAHA administration, we performed a genetic cross to determine whether genetic reduction of Hdac7 would alleviate phenotypes in the R6/2 mice.

Similarly, the dysregulated expression levels of a number of genes of interest were not improved suggesting that reduction in Hdac7 does not alleviate the R6/2 HD-related transcriptional dysregulation.

However, loss of normal huntingtin function resulting from the polyglutamine expansion might also contribute to the pathogenesis of HD. Here, we have studied the effects of huntingtin knockdown in zebrafish using morpholino antisense oligonucleotides, as its huntingtin orthologue has 70% amino acid identity with the human protein. Reduced huntingtin levels did not impact on gastrulation and early development, but caused massive apoptosis of neuronal cells by 24 hpf. This was accompanied by impaired neuronal development, resulting in small eyes and heads and enlargement of brain ventricles. Older huntingtin knockdown fish developed lower jaw abnormalities with most branchial arches missing. Molecular analysis revealed that BDNF expression was reduced by approximately 50%. Reduction of BDNF levels by injection of a BDNF morpholino resulted in phenotypes very similar to those seen in huntingtin knockdown zebrafish. The phenotypes of both huntingtin- and BDNF-knockdown zebrafish showed significant rescue when treated with exogenous BDNF protein.

We find that Cos-7 and PC-12 cells in culture readily take up aggregates of chemically synthesized poly(Q) peptides. Simple poly(Q) aggregates are localized to the cytoplasm and have little impact on cell viability. Aggregates of poly(Q) peptides containing a nuclear localization signal, however, are localized to nuclei and lead to dramatic cell death.

The molecular trigger of HD is a polyglutamine expansion in the Huntingtin protein (Htt). The mutant Htt protein forms insoluble nuclear aggregates which have been proposed to play a key role in causing neuronal cell death in HD. Other lines of investigation suggest that expression of mutant Htt facilitates activity of the NR2B subtype of NMDA receptors and the type 1 inositol 1,4,5-trisphosphate receptors (InsP(3)R1), and that disturbed calcium (Ca(2+)) signaling causes apoptosis of MSNs in HD. The YAC128 transgenic HD mouse model expresses the full-length human Htt protein with 120Q CAG repeat expansion and displays an age-dependent loss of striatal neurons as seen in human HD brain. In contrast, the shortstop mice express an amino-terminal fragment of the mutant Htt protein (exons 1 and 2) and display no behavioral abnormalities or striatal neurodegeneration despite widespread formation of neuronal inclusions. Here we compared Ca(2+) signals in primary MSN neuronal cultures derived from YAC128 and shortstop mice to their wild-type non-transgenic littermates. Repetitive application of glutamate results in supranormal Ca(2+) responses in YAC128 MSNs, but not in shortstop MSNs. In addition, while currents mediated by the NR2B subtype of NMDA receptors were increased in YAC128 MSNs, currents in SS MSNs were found to be similar to WT. Furthermore, YAC128 MSNs were sensitized to glutamate-induced apoptosis. Consistent with these findings, we found that application of glutamate induced rapid loss of mitochondrial membrane potential in YAC128 MSNs. In contrast, SS MSNs do not show increased cell death postglutamate treatment nor accelerated loss of mitochondrial membrane potential following glutamate stimulation. Glutamate-induced loss of mitochondrial membrane potential in YAC128 MSNs could be prevented by inhibitors of NR2B NMDA receptors and mGluR1/5 receptors. Our results are consistent with the hypothesis that disturbed neuronal Ca(2+) signaling plays a significant role in the degeneration of MSN containing full-length mutant Htt(exp).

Moreover, a 17-bp variable number of tandem repeat (VNTR) polymorphism of the second intron may act as a transcriptional regulator with allele dependent differential enhancer-like properties. Since the 5-HTT of human platelets shares many properties with the transporter of neural tissue, platelets are widely used as a surrogate tissue source, possibly reflecting central 5-HT metabolism. Therefore, we investigated the impact of the 44-bp polymorphism and the 17-bp VNTR for 5-HT uptake in platelets of 50 male subjects. We found no significant effect of the 44-bp polymorphism and of the 17-bp VNTR on maximum rate (Vmax) of 5-HT uptake.

In this regard, the YAC128 mouse model, expressing full-length human huntingtin with 128 glutamine repeats, has been the focus of much interest. Although NMDA-induced apoptosis is enhanced in YAC128 MSNs, here we report that the initial steps in the death signaling pathway, including NMDA receptor (NMDAR) current and cytosolic Ca2+ loading, are similar to those observed in wild-type MSNs. In contrast, we found that the NMDAR-mediated Ca2+ load triggered a strikingly enhanced loss of mitochondrial membrane potential in YAC128 MSNs, suggesting that NMDAR signaling via the mitochondrial apoptotic pathway is altered. This effect was accompanied by impaired cytosolic Ca2+ clearance after removal of NMDA, a difference that was not apparent after high potassium-evoked depolarization-mediated Ca2+ entry. Inhibition of the mitochondrial permeability transition (mPT) reduced peak cytosolic Ca2+ and mitochondrial depolarization evoked by NMDA in YAC128 MSNs but not wild-type MSNs. Hence, in contrast to YAC models with moderate CAG expansions, the enhanced NMDA-induced apoptosis in YAC128 MSNs is predominantly determined by augmented mitochondrial sensitivity to Ca2+-induced activation of the mPT.

Selective markers of both striatal projection and interneurons such as dopamine and c-AMP-related phosphoprotein, calretinin, acetylcholinesterase, choline acetyltransferase, tyrosine hydroxylase, calbindin, enkephalin, and substance P showed positive transplant regions clearly innervated by host tyrosine hydroxylase fibers. There was no histological evidence of immune rejection including microglia and macrophages. Notably, neuronal protein aggregates of mutated huntingtin, which is typical HD neuropathology, were not found within the transplanted fetal tissue. Thus, although there is a genetically predetermined process causing neuronal death within the HD striatum, implanted fetal neural cells lacking the mutant HD gene may be able to replace damaged host neurons and reconstitute damaged neuronal connections. This study demonstrates that grafts derived from human fetal striatal tissue can survive, develop, and are unaffected by the disease process, at least for 18 months, after transplantation into a patient with HD.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:18077673" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:11106399" }, { - "id": "pmid:18068007", + "id": "pmid:11105061", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/18068007", - "title": "Analysis of CCG repeats in Huntingtin gene among HD patients and normal populations in Japan.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/11105061", + "title": "Huntington disease: DNA analysis in Brazilian population.", "type": "article-journal", - "doi": "10.1016/j.arcmed.2007.06.015", + "doi": "10.1590/s0004-282x2000000600001", "authors": [ - ["Saeid", "Morovvati"], - ["Masanori", "Nakagawa"], - ["Mitsuhiro", "Osame"], - ["Ali", "Karami"] + ["S", "Raskin"], + ["N", "Allan"], + ["H A", "Teive"], + ["F", "Cardoso"], + ["M S", "Haddad"], + ["G", "Levi"], + ["R", "Boy"], + ["J", "Lerena Junior"], + ["V S", "Sotomaior"], + ["M", "Janzen-D\u00fcck"], + ["L B", "Jardim"], + ["F R", "Fellander"], + ["L A", "Andrade"] ], - "publisher": "Archives of medical research", - "issn": "0188-4409", - "date": "2007-08-23", - "abstract": "Huntington's disease (HD) is a hereditary autosomal dominant neurodegenerative disease characterized by motor, cognitive, and psychiatric symptoms.

A growing number of studies demonstrate that personality, mood and cognitive disturbances are some of the earliest signs of HD and may reflect synaptic dysfunction prior to neuronal loss. Previous studies in striatal MSNs demonstrated early alterations in NMDA-type glutamate receptor currents in several HD mouse models, as well as evidence for presynaptic dysfunction prior to disease manifestations in the R6/2 HD fragment mouse model. We have compared corticostriatal synaptic function in full-length, human HD gene-carrying YAC transgenic mice expressing a non-pathogenic CAG repeat (YAC18; control) with three increasingly severe variants of pathogenic HD gene-expressing mice (YAC72 and two different lines of YAC128), at ages that precede any detectable disease phenotype. We report presynaptic dysfunction and a propensity towards synaptic depression in YAC72 and YAC128 compared to YAC18 mice, and, in the most severe model, we also observed altered AMPA receptor function. When normalized to evoked AMPAR currents, postsynaptic NMDAR currents are augmented in all three pathogenic HD YAC variants. These findings demonstrate multiple perturbations to corticostriatal synaptic function in HD mice, furthering our understanding of the early effects of the HD mutation that may contribute to cognitive dysfunction, mood disorders and later development of more serious dysfunction.

We found that CAG/CTG repeats are stable in RAD27 +/- cells if the tract is 70 repeats long and exhibit a slightly increased expansion frequency if the tract is 85 or 130 repeats long. However for CAG-155 tracts, the repeat expansion frequency in RAD27 +/- cells is significantly higher than in RAD27 +/+ cells. This data indicates that cells containing longer CAG/CTG repeats need more Fen1 protein to maintain tract stability and that maintenance of long CAG/CTG repeats is particularly sensitive to Fen1 levels. Our results may explain the relatively small effects seen in the Huntington's disease (HD) FEN1 +/- heterozygous mice and myotonic dystrophy type 1 (DM1) FEN1 +/- heterozygous mice, and suggest that inefficient flap processing by Fen1 could play a role in the continued expansions seen in humans with trinucleotide repeat expansion diseases.", + "publisher": "Philosophical transactions of the Royal Society of London.

The disease is caused by expansion of a CAG (glutamine) repeat within the coding region of the HD gene. The molecular mechanism by which the mutated protein causes this disease is still unclear. To study the protein we have generated a set of rabbit polyclonal antibodies raised against different segments of the N-terminal, central and C-terminal parts of the protein. The polyclonal antibodies were affinity purified and characterized in ELISA and Western blotting experiments. All antibodies can react with mouse and human proteins. The specificity of these antibodies is underscored by their recognition of huntingtin with different repeat sizes in extracts prepared from patient-derived lymphoblasts. The antibodies were used in immunofluorescence experiments to study the subcellular localization of huntingtin in mouse neuroblastoma NIE-115 cells. The results indicate that most huntingtin is present in the cytoplasm, whereas a minor fraction is present in the nucleus. On differentiation of the NIE-115 cells in vitro, the subcellular distribution of huntingtin does not change significantly. These results suggest that full-length huntingtin with a normal repeat length can be detected in the nucleus of cycling and non-cycling cultured mammalian cells of neuronal origin. However, in HD autopsy brain the huntingtin-containing neuronal intranuclear inclusions can be detected only with antibodies raised against the N-terminus of huntingtin. Thus several forms of huntingtin display the propensity for nuclear localization, possibly with different functional consequences.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:17383831" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:10434306" }, { - "id": "pmid:17363167", + "id": "pmid:10434303", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/17363167", - "title": "Plasma neurofilament heavy chain levels in Huntington's disease.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/10434303", + "title": "Transgenic mice expressing mutated full-length HD cDNA: a paradigm for locomotor changes and selective neuronal loss in Huntington's disease.", "type": "article-journal", - "doi": "10.1016/j.neulet.2007.02.053", + "doi": "10.1098/rstb.1999.0456", "authors": [ - ["Edward J", "Wild"], - ["Axel", "Petzold"], - ["Geoff", "Keir"], - ["Sarah J", "Tabrizi"] + ["P H", "Reddy"], + ["V", "Charles"], + ["M", "Williams"], + ["G", "Miller"], + ["W O", "Whetsell"], + ["D A", "Tagle"] ], - "publisher": "Neuroscience letters", - "issn": "0304-3940", - "date": "2007-02-24", - "abstract": "There is a need for biomarkers of onset and progression in Huntington's disease (HD), as current outcome measures lack the reliability to enable the efficient conduct of disease-modifying trials.

We have recently created HD full-length cDNA transgenic mouse models that may serve as a paradigm for HD. A more detailed characterization of these models is presented here. The transgene encoding normal huntingtin consists of 9417 bp of the huntingtin coding sequences including 16 tandem CAGs coding for polyglutamines as part of exon 1. The transgene is driven by a heterologous cytomegalovirus promoter. Five independent transgenic mouse lines were obtained using this construct. An additional six transgenic lines were obtained using full-length HD constructs that have been modified to include either 48 or 89 CAG repeat expansions. Southern blot and densitometric analyses indicated unique integration sites for the transgene in each of the lines with a copy number ranging from two to 22 copies. Widespread expression of the transgene in brain, heart, spleen, kidney, lung, liver and gonads from each line was determined by Western blot analyses. In the brain, transgene expression was found in cerebral cortex, striatum, hippocampus and cerebellum. Expression of the transgene was as much as five times the endogenous mouse huntingtin level. Phenotypically, only mice expressing 48 or 89 CAG repeats manifested progressive behavioural and motor dysfunction. Early behavioural abnormalities were characterized by trunk curling and clasping of both fore- and hindlimbs when the animals were suspended by their tails. Subsequently, these mice exhibited hyperkinetic movements, including heightened exploratory activities, unidirectional rotational behaviour, backflipping and excessive grooming that lasted for several weeks. Eventually, the animals progressed to a hypokinetic phase consisting of slowed movements and lack of response to sensory stimuli. Urine retention or incontinence was also a prominent feature of the hypokinetic phase. At the end stage of the disease process, HD48(B,D) and HD89(A-C) mice became akinetic just prior to death. Neuropathological examination of mice at various stages indicated that it was only during the hypokinetic phase and thereafter when selective neuronal loss was most apparent. Regions of neurodegeneration and loss included the striatum, cerebral cortex, thalamus and hippocampus. TUNEL staining indicated an apoptotic mode of cell death in these brain regions. Comparative neuronal counts after Nissl staining showed as much as 20% loss of small and medium neurons in the striatum in mice at the hypokinetic and akinetic stages. Reactive astrocytosis accompanied the areas of neurodegeneration and loss. Polyglutamine aggregates in the form of neuronal intranuclear inclusions and diffuse nuclear and perinuclear aggregations were found in a small percentage of neurons, including those in brain regions that are typically spared in HD. This observation suggests that polyglutamine aggregates may not be sufficient to cause neuronal loss in HD. In both behavioural and neuropathological analyses, wild-type and transgenic animals with 16 CAG repeats were indistinguishable from each other and do not exhibit the changes observed for mice carrying the 48 and 89 CAG repeat mutations. Thus, animals expressing the CAG repeat expansions appear to represent clinically analogous models for HD pathogenesis, and may also provide insights into the underlying pathophysiological mechanisms of other triplet repeat disorders.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:17363167" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:10434303" }, { - "id": "pmid:17356014", + "id": "pmid:10398087", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/17356014", - "title": "Extended polyglutamine repeats trigger a feedback loop involving the mitochondrial complex III, the proteasome and huntingtin aggregates.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/10398087", + "title": "Frequent expansion of Epstein-Barr virus (EBV) infected cells in germinal centres of tonsils from an area with a high incidence of EBV-associated lymphoma.", "type": "article-journal", - "doi": "10.1093/hmg/ddm023", + "doi": "10.1002/(sici)1096-9896(199902)187:3<326::aid-path242>3.0.co;2-n", "authors": [ - ["Hirokazu", "Fukui"], - ["Carlos T", "Moraes"] + ["I", "Araujo"], + ["H D", "Foss"], + ["M", "Hummel"], + ["I", "Anagnostopoulos"], + ["H S", "Barbosa"], + ["A", "Bittencourt"], + ["H", "Stein"] ], - "publisher": "Human molecular genetics", - "issn": "0964-6906", - "date": "2007-03-13", - "abstract": "Mitochondrial abnormalities represent a major cytopathology in Huntington's disease (HD), a fatal neurodegenerative disease caused by CAG repeat expansions in the gene encoding huntingtin (Htt).

To take advantage of existing mitochondrial DNA mutants, we developed human osteosarcoma 143B cells expressing mutant Htt in an inducible manner and found that cells expressing mutant Htt but not wild-type Htt exhibited a reduced activity of complex III and an increased activity of complex IV.

This complex III-mediated modulation of Htt aggregates was also observed in a neuronal progenitor RN33B cell line transduced by lentivirus carrying mutant Htt.

Accordingly, complex III mutant cells also showed decreased proteasome activity.

Although the overall EBV infection rate was similar in both groups (50 per cent of Bahian vs. 45 per cent of German cases), a significantly higher number of EBER-positive lymphoid cells were found in the GCs of 8/20 EBV-positive tonsils from Brazil (9-89 cells/GC; mean: 14.5 cells/GC per case), while only 3/18 tonsils from Germany displayed a few EBER positive cells (1-9 cells/GC; mean: 0.5 cell/GC per case) in this compartment (p < 0.007). In addition, the EBV-infected GC cells in Bahian samples resembled centroblasts, exhibited mitotic activity, and in two cases showed expression of EBV-encoded latent membrane protein (LMP)-1, findings not present in German samples. These data show that latently EBV-infected cells participate more frequently in GC reactions in developing regions than in industrialized countries and may abnormally express the oncogenic protein LMP-1.

Traditionally, the large cholinergic striatal interneurons are believed to be spared. Recent studies demonstrate that neuronal dysfunction without cell death also plays an important role in early and mid-stages of the disease. Here, we report that cholinergic transmission is affected in a HD transgenic mouse model (R6/1) and in tissues from HD patients. Stereological analysis shows no loss of cholinergic neurons in the striatum or septum in R6/1 mice. In contrast, the levels of mRNA and protein for vesicular acetylcholine transporter (VAChT) and choline acetyltransferase (ChAT) are decreased in the striatum and cortex, and acetylcholine esterase activity is lowered in the striatum of R6/1 mice already at young ages. Accordingly, VAChT is also reduced in striatal tissue from patients with HD. The decrease of VAChT in the patient samples studied is restricted to the striatum and does not occur in the hippocampus or the spinal cord. The expression and localization of REST/NRSF, a transcriptional regulator for the VAChT and ChAT genes, are not altered in cholinergic neurons.

To gain insight into the regulation of the HD gene we analysed 1348 bp of the rat huntingtin promoter region. This region lacks a TATA and a CAAT box, is rich in GC content and has several consensus sequences for binding sites for SP1, PEA3, Sif and H2A.

The serotonin transporter gene (5-HTT) is considered as a candidate gene for BPD as multiple lines of evidence have suggested that it plays an important role in suicide, impulsive behaviour, and emotional liability.

Besides the polyGln sequence, the cellular context of the disease protein, and the sequence context of the polyGln within the disease protein, are both likely to contribute to polyGln physical behavior and to pathology. In HD, the N-terminal, exon-1 segment of the protein huntingtin contains the polyGln sequence immediately followed by an oligoproline region. We show here that introduction of a P10 sequence C-terminal to polyGln in synthetic peptides decreases both the rate of formation and the apparent stability of the amyloid-like aggregates associated with this family of diseases. The sequence can be trimmed to P6 without altering the suppression, but a P3 sequence is ineffective. Spacers up to at least three amino acid residues in length can be inserted between polyGln and P10 without altering this effect. There is no suppression, however, when the P10 sequence is either placed on the N-terminal side of polyGln or attached to polyGln via a side-chain tether. The nucleation mechanism of a Q40 sequence is unchanged upon addition of a P10 C-terminal extension, yielding a critical nucleus of one. The effects of oligoPro length and structural context on polyGln aggregation are correlated strongly with alterations in the circular dichroism spectra of the monomeric peptides.

Furthermore, both germ-line and somatic-cell instability are likely to be mitotic defects, the former occurring early in embryogenesis. To test the hypothesis that defective repair is a common prerequisite for instability, we have utilized two disease groups that represent different instability \"conditions.\" Germ-line instability within simple tandem repeats (STR) at 10 loci in 29 HD families were compared with somatic instability at the same loci in 26 colon cancer (CC) patients with identified or suspected defects in mismatch-repair enzymes.

HD is spread worldwide and it is generally accepted that few mutational events account for the origin of the pathogenic CAG expansion in most populations. We have investigated the genetic history of HD mutation in 83 family probands from the Land of Valencia, in Eastern Spain. An analysis of the HD/CCG repeat in informative families suggested that at least two main chromosomes were associated in the Valencian population, one associated with allele 7 (77 mutant chromosomes) and one associated with allele 10 (two mutant chromosomes). Haplotype A-7-A (H1) was observed in 47 out of 48 phase-known mutant chromosomes, obtained by segregation analysis, through the haplotype analysis of rs1313770-HD/CCG-rs82334, as it also was in 120 out of 166 chromosomes constructed by means of the PHASE program. The genetic history and geographical distribution of the main haplotype H1 were both studied by constructing extended haplotypes with flanking short tandem repeats (STRs) D4S106 and D4S3034. We found that we were able to determine the age of the CAG expansion associated with the haplotype H1 as being between 4,700 and 10,000 years ago.

We find that the change in repeat length with paternal transmission is significantly correlated with the change in age at onset between the father and offspring. When expanded triplet repeats of affected parents are separated by median repeat length, we find that the longer paternal and maternal repeats are both more unstable on transmission. However, unlike in paternal transmission, in which longer expanded repeats display greater net expansion than do shorter expanded repeats, in maternal transmission there is no mean change in repeat length for either longer or shorter expanded repeats. We also confirmed the inverse relationship between repeat length and age at onset, the higher frequency of juvenile-onset cases arising from paternal transmission, anticipation as a phenomenon of paternal transmission, and greater expansion of the trinucleotide repeat with paternal transmission. Stepwise multiple regression indicates that, in addition to repeat length of offspring, age at onset of affected parent and sex of affected parent contribute significantly to the variance in age at onset of the offspring. Thus, in addition to triplet repeat length, other factors, which could act as environmental factors, genetic factors, or both, contribute to age at onset.

The other twin, who is without symptoms at present, displayed mosaicism in skin fibroblasts and hair roots. If the proportion of the two cell lines in the brain of each twin resembles that of their hair roots (another tissue originating from the ectoderm), the mosaicism in the unaffected twin would mean that only a part of his brain cells carried the expanded allele, which could explain why he, in contrast to his brother, has no symptoms at this time.", + "publisher": "American journal of human genetics", + "issn": "0002-9297", + "date": "1995-08-01", + "abstract": "A total of 254 affected parent-child pairs with Huntington disease (HD) and 440 parent-child pairs with CAG size in the normal range were assessed to determine the nature and frequency of intergenerational CAG changes in the HD gene. Intergenerational CAG changes are extremely rare (3/440 [0.68%]) on normal chromosomes. In contrast, on HD chromosomes, changes in CAG size occur in approximately 70% of meioses on HD chromosomes, with expansions accounting for 73% of these changes. These intergenerational CAG changes make a significant but minor contribution to changes in age at onset (r2 = .19). The size of the CAG repeat influenced larger intergenerational expansions (> 7 CAG repeats), but the likelihood of smaller expansions or contractions was not influenced by CAG size. Large expansions (> 7 CAG repeats) occur almost exclusively through paternal transmission (0.96%; P < 10(-7)), while offspring of affected mothers are more likely to show no change (P = .01) or contractions in CAG size (P = .002). This study demonstrates that sex of the transmitting parent is the major determinant for CAG intergenerational changes in the HD gene. Similar paternal sex effects are seen in the evolution of new mutations for HD from intermediate alleles and for large expansions on affected chromosomes. Affected mothers almost never transmit a significantly expanded CAG repeat, despite the fact that many have similar large-sized alleles, compared with affected fathers. The sex-dependent effects of major expansion and contractions of the CAG repeat in the HD gene implicate different effects of gametogenesis, in males versus females, on intergenerational CAG repeat stability.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:15372528" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:7668260" }, { - "id": "pmid:15345132", + "id": "pmid:7639626", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/15345132", - "title": "In vitro proliferation and expansion of hematopoietic progenitors present in mobilized peripheral blood from normal subjects and cancer patients.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/7639626", + "title": "Correlations between triplet repeat expansion and clinical features in Huntington's disease.", "type": "article-journal", - "doi": "10.1089/scd.2004.13.382", + "doi": "10.1001/archneur.1995.00540320021009", "authors": [ - ["Guadalupe", "Mart\u00ednez-Jaramillo"], - ["Patricia", "Flores-Guzm\u00e1n"], - ["Juan Jos\u00e9", "Montesinos"], - ["Sandra", "Quintana"], - ["Javier", "Bautista"], - ["Elizabeth", "S\u00e1nchez-Valle"], - ["Mar\u00eda", "de Jes\u00fas Nambo"], - ["Hector", "Mayani"] + ["S", "Claes"], + ["K", "Van Zand"], + ["E", "Legius"], + ["R", "Dom"], + ["M", "Malfroid"], + ["F", "Baro"], + ["J", "Godderis"], + ["J J", "Cassiman"] ], - "publisher": "Stem cells and development", - "issn": "1547-3287", - "date": "2004-08-01", - "abstract": "In the present study, we have assessed, in a comparative manner, the in vitro proliferation and expansion potentials of hematopoietic progenitor cells (HPC) present in mobilized peripheral blood from normal subjects (MPB-n; n = 18) and cancer patients (MPB-c; n = 18).

Enriching the environment of HD transgenic mice delays the onset of symptoms, so we also examine the effects of enrichment on dendrite pathology. Golgi-impregnated tissue from symptomatic R6/1 HD mice reveals a decrease in dendritic spine density and dendritic spine length in striatal medium spiny neurons and cortical pyramidal neurons. HD also causes a specific reduction in the proportion of bifurcated dendritic spines on basal dendrites of cortical pyramidal neurons. No differences in soma size, recurving distal dendrites, or dendritic branching were observed. Although home-cage environmental enrichment from 1 to 8 months of age increases spine density in wild-type mice, it has no effect on the spine pathology in HD mice. These results show that dendritic spine pathology in R6/1 HD mice resembles degenerative changes seen in human HD and in other transgenic mouse models of the disease.

The results show a highly significant inverse relationship between CAG and CCG repeat lengths. In populations with lowered prevalence rates of HD, CAG repeat lengths are smaller and the distribution of CCG alleles is markedly different from Western European populations.

The molecular pathways leading to the selectivity of neuronal cell death in HD are poorly understood. Proteolytic processing of full-length mutant huntingtin (Htt) and subsequent events may play an important role in the selective neuronal cell death found in this disease. Despite the identification of Htt as a substrate for caspases, it is not known which caspase(s) cleaves Htt in vivo or whether regional expression of caspases contribute to selective neuronal cells loss. Here, we evaluate whether specific caspases are involved in cell death induced by mutant Htt and if this correlates with our recent finding that Htt is cleaved in vivo at the caspase consensus site 552. We find that caspase-2 cleaves Htt selectively at amino acid 552. Further, Htt recruits caspase-2 into an apoptosome-like complex. Binding of caspase-2 to Htt is polyglutamine repeat-length dependent, and therefore may serve as a critical initiation step in HD cell death. This hypothesis is supported by the requirement of caspase-2 for the death of mouse primary striatal cells derived from HD transgenic mice expressing full-length Htt (YAC72). Expression of catalytically inactive (dominant-negative) forms of caspase-2, caspase-7, and to some extent caspase-6, reduced the cell death of YAC72 primary striatal cells, while the catalytically inactive forms of caspase-3, -8, and -9 did not. Histological analysis of post-mortem human brain tissue and YAC72 mice revealed activation of caspases and enhanced caspase-2 immunoreactivity in medium spiny neurons of the striatum and the cortical projection neurons when compared to controls. Further, upregulation of caspase-2 correlates directly with decreased levels of brain-derived neurotrophic factor in the cortex and striatum of 3-month YAC72 transgenic mice and therefore suggests that these changes are early events in HD pathogenesis.

To address these questions, we produced aggregates of simple poly(Q) peptides in vitro and introduced them to mammalian cells in culture. We find that Cos-7 and PC-12 cells in culture readily take up aggregates of chemically synthesized poly(Q) peptides. Simple poly(Q) aggregates are localized to the cytoplasm and have little impact on cell viability. Aggregates of poly(Q) peptides containing a nuclear localization signal, however, are localized to nuclei and lead to dramatic cell death. Amyloid fibrils of a non-poly(Q) peptide are non-toxic, whether localized to the cytoplasm or nucleus. Nuclear localization of an aggregate of a short, Q(20), poly(Q) peptide is just as toxic as that of a long poly(Q) peptide, supporting the notion that the influence of poly(Q) repeat length on disease risk and age of onset is at the level of aggregation efficiency.

It has never been clear, however, whether duplex unpairing occurs during mitotic replication or during strand-break repair. In simple organisms, trinucleotide expansion arises by replication slippage on either the leading or the lagging strand, homologous recombination, gene conversion, double-strand break repair and base excision repair; it is not clear which of these mechanisms is used in mammalian cells in vivo. We have followed heritable changes in CAG length in male transgenic mice.

Intestinal mucin has been known to be affected by dietary threonine supply since de novo synthesis of mucin proteins is sensitive to luminal threonine concentration. However, it is unknown whether biosynthesis of MUC1 is regulated by threonine in human cancers. In this study, data provided suggests that threonine starvation reduces the level of MUC1 and inhibits the migration of MUC1-expressing pancreatic cancer cells. Interestingly, knockdown of threonyl-tRNA synthetase (TRS), an enzyme that catalyzes the ligation of threonine to its cognate tRNA, also suppresses MUC1 levels but not mRNA levels. The inhibitors of TRS decrease the level of MUC1 protein and prohibit the migration of MUC1-expressing pancreatic cancer cells. In addition, a positive correlation between TRS and MUC1 levels is observed in human pancreatic cancer cells. Concurrent with these results, the bioinformatics data indicate that co-expression of both TRS and MUC1 is correlated with the poor survival of pancreatic cancer patients.

We have recently created HD full-length cDNA transgenic mouse models that may serve as a paradigm for HD. A more detailed characterization of these models is presented here. The transgene encoding normal huntingtin consists of 9417 bp of the huntingtin coding sequences including 16 tandem CAGs coding for polyglutamines as part of exon 1. The transgene is driven by a heterologous cytomegalovirus promoter. Five independent transgenic mouse lines were obtained using this construct. An additional six transgenic lines were obtained using full-length HD constructs that have been modified to include either 48 or 89 CAG repeat expansions. Southern blot and densitometric analyses indicated unique integration sites for the transgene in each of the lines with a copy number ranging from two to 22 copies. Widespread expression of the transgene in brain, heart, spleen, kidney, lung, liver and gonads from each line was determined by Western blot analyses. In the brain, transgene expression was found in cerebral cortex, striatum, hippocampus and cerebellum. Expression of the transgene was as much as five times the endogenous mouse huntingtin level. Phenotypically, only mice expressing 48 or 89 CAG repeats manifested progressive behavioural and motor dysfunction. Early behavioural abnormalities were characterized by trunk curling and clasping of both fore- and hindlimbs when the animals were suspended by their tails. Subsequently, these mice exhibited hyperkinetic movements, including heightened exploratory activities, unidirectional rotational behaviour, backflipping and excessive grooming that lasted for several weeks. Eventually, the animals progressed to a hypokinetic phase consisting of slowed movements and lack of response to sensory stimuli. Urine retention or incontinence was also a prominent feature of the hypokinetic phase. At the end stage of the disease process, HD48(B,D) and HD89(A-C) mice became akinetic just prior to death. Neuropathological examination of mice at various stages indicated that it was only during the hypokinetic phase and thereafter when selective neuronal loss was most apparent. Regions of neurodegeneration and loss included the striatum, cerebral cortex, thalamus and hippocampus. TUNEL staining indicated an apoptotic mode of cell death in these brain regions. Comparative neuronal counts after Nissl staining showed as much as 20% loss of small and medium neurons in the striatum in mice at the hypokinetic and akinetic stages. Reactive astrocytosis accompanied the areas of neurodegeneration and loss. Polyglutamine aggregates in the form of neuronal intranuclear inclusions and diffuse nuclear and perinuclear aggregations were found in a small percentage of neurons, including those in brain regions that are typically spared in HD. This observation suggests that polyglutamine aggregates may not be sufficient to cause neuronal loss in HD. In both behavioural and neuropathological analyses, wild-type and transgenic animals with 16 CAG repeats were indistinguishable from each other and do not exhibit the changes observed for mice carrying the 48 and 89 CAG repeat mutations. Thus, animals expressing the CAG repeat expansions appear to represent clinically analogous models for HD pathogenesis, and may also provide insights into the underlying pathophysiological mechanisms of other triplet repeat disorders.", + "publisher": "Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologica", + "issn": "0100-879X", + "date": "2007-06-01", + "abstract": "Pregnancy loss can be caused by several factors involved in human reproduction.

The study was conducted on 10 women aged 25 to 35 years with no history of successful pregnancy and with a diagnosis of infertility.

Statistical analysis showed no significant difference in the number of MUC-1 variable number of tandem repeats between these groups (P > 0.05). Our results suggest that there is no effect of the polymorphic MUC-1 sequence on the implantation failure. However, the data do not exclude MUC-1 relevance during embryo implantation.

Although the overall EBV infection rate was similar in both groups (50 per cent of Bahian vs. 45 per cent of German cases), a significantly higher number of EBER-positive lymphoid cells were found in the GCs of 8/20 EBV-positive tonsils from Brazil (9-89 cells/GC; mean: 14.5 cells/GC per case), while only 3/18 tonsils from Germany displayed a few EBER positive cells (1-9 cells/GC; mean: 0.5 cell/GC per case) in this compartment (p < 0.007). In addition, the EBV-infected GC cells in Bahian samples resembled centroblasts, exhibited mitotic activity, and in two cases showed expression of EBV-encoded latent membrane protein (LMP)-1, findings not present in German samples. These data show that latently EBV-infected cells participate more frequently in GC reactions in developing regions than in industrialized countries and may abnormally express the oncogenic protein LMP-1. This could in part explain the higher incidence in this region of EBV association with lymphomas related to GC cells or their progeny, such as BL and HD.", + "publisher": "Glycobiology", + "issn": "0959-6658", + "date": "2006-10-18", + "abstract": "The cell membrane mucin MUC1 is over-expressed and aberrantly glycosylated in many cancers, and cancer-associated MUC1 glycoforms represent potential targets for immunodiagnostic and therapeutic measures. We have recently shown that MUC1 with GalNAcalpha1-O-Ser/Thr (Tn) and NeuAcalpha2-6GalNAcalpha1-O-Ser/Thr (STn) O-glycosylation is a cancer-specific glycoform, and that Tn/STn-MUC1 glycopeptide-based vaccines can override tolerance in human MUC1 transgenic mice and induce humoral immunity with high specificity for MUC1 cancer-specific glycoforms (Sorensen AL, Reis CA, Tarp MA, Mandel U, Ramachandran K, Sankaranarayanan V, Schwientek T, Graham R, Taylor-Papadimitriou J, Hollingsworth MA, et al. 2006.

In order to further characterize the immune response to Tn/STn-MUC1 glycoforms, we generated monoclonal antibodies with specificity similar to the polyclonal antibody response found in transgenic mice. In the present study, we define the immunodominant epitope on Tn/STn-MUC1 glycopeptides to the region including the amino acids GSTA of the MUC1 20-amino acid tandem repeat (HGVTSAPDTRPAPGSTAPPA). Most other MUC1 antibodies are directed to the PDTR region, although patients with antibodies to the GSTA region have been identified. A panel of other MUC1 glycoform-specific monoclonal antibodies was included for comparison. The study demonstrates that the GSTA region of the MUC1 tandem repeat contains a highly immunodominant epitope when presented with immature short O-glycans. The cancer-specific expression of this glycopeptide epitope makes it a prime candidate for immunodiagnostic and therapeutic measures.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:10398087" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:17050588" }, { - "id": "pmid:10334474", + "id": "pmid:16631167", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/10334474", - "title": "Accurate determination of the number of CAG repeats in the Huntington disease gene using a sequence-specific internal DNA standard.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/16631167", + "title": "MUC1 splice variants in human ocular surface tissues: possible differences between dry eye patients and normal controls.", "type": "article-journal", - "doi": "10.1034/j.1399-0004.1999.550308.x", + "doi": "10.1016/j.exer.2006.01.031", "authors": [ - ["O", "Bruland"], - ["E W", "Almqvist"], - ["Y P", "Goldberg"], - ["H", "Boman"], - ["M R", "Hayden"], - ["P M", "Knappskog"] + ["Yoannis", "Imbert"], + ["Douglas S", "Darling"], + ["Marcia M", "Jumblatt"], + ["Gary N", "Foulks"], + ["Erica G", "Couzin"], + ["Pamela S", "Steele"], + ["William W", "Young"] ], - "publisher": "Clinical genetics", - "issn": "0009-9163", - "date": "1999-03-01", - "abstract": "We have developed a sequence-specific internal DNA size standard for the accurate determination of the number of CAG repeats in the Huntington disease (HD) gene by cloning key fragments (between 15 and 64 CAG repeats) of the HD gene.

Comparison of the calculated numbers of CAG repeats in the HD gene using this sequence-specific DNA standard with a commercially available standard (GENESCAN-500 TAMRA) showed that the latter underestimated the number of CAG repeats by three when analyzed by capillary electrophoresis on the ABI 310 Genetic Analyzer (POP4 polymer).

Mucins act as lubricants, protectants, and mediators of signal transduction. The majority of the O-glycosylation sites on the transmembrane mucin MUC1 are found in a highly polymorphic core region containing a variable number of tandem repeats (VNTR). MUC1 alleles can be divided into size classes that contain small (30-45) or large (60-90) numbers of repeats. Although at least 12 splice variants of MUC1 have been found in other tissues, no splice variants have been reported in human ocular surface tissues. We have used RT-PCR to identify MUC1 splice variants that were then confirmed by sequencing. We here report the presence in some samples of human cornea, conjunctiva, and lacrimal gland of MUC1/B which features canonical splicing between exons 1 and 2 and MUC1/A, a transcript that retains 27bp from the 3' end of intron 1 and is predicted to add 9 amino acids to the MUC1 sequence upstream of the tandem repeat region. Cornea and conjunctiva both contain the MUC1/SEC splice variant that lacks the transmembrane domain and, therefore, results in a soluble, secreted form of MUC1. Cornea and conjunctiva also contain MUC1/Y and MUC1/Z(X) variants that lack the tandem repeat region. Cornea, conjunctiva, and lacrimal gland also contain a previously undescribed MUC1 variant transcript, termed MUC1/YI, that retains 99bp from the 5' end and 27bp from the 3' end of the first intron, resulting in a frame shift and premature stop codon. This transcript is predicted to produce a novel 27 amino acid peptide after signal peptidase cleavage. Analysis of brush cytology samples revealed that the percentage of dry eye patients expressing the MUC1/A variant in the conjunctival epithelium is lower than in normal control donors. Western blotting confirmed that MUC1/A is associated with alleles containing the large size class of tandem repeats. Therefore, we propose that one factor in susceptibility to dry eye disease may be the lengths of the MUC1 VNTR in conjunctival epithelium based on the rationale that longer VNTR provide better lubrication and greater protection of the ocular surface against inflammation.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:10334474" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:16631167" }, { - "id": "pmid:10333377", + "id": "pmid:16302687", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/10333377", - "title": "Behavioral effects of tryptophan depletion in seasonal affective disorder associated with the serotonin transporter gene?", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/16302687", + "title": "The production and characterization of novel heavy-chain antibodies against the tandem repeat region of MUC1 mucin.", "type": "article-journal", - "doi": "10.1016/s0165-1781(99)00009-8", + "doi": "10.1080/08820130500265356", "authors": [ - ["E", "Lenzinger"], - ["A", "Neumeister"], - ["N", "Praschak-Rieder"], - ["K", "Fuchs"], - ["E", "Gerhard"], - ["M", "Willeit"], - ["W", "Sieghart"], - ["S F", "Kasper"], - ["K", "Hornik"], - ["H N", "Aschauer"] + ["Fatemeh", "Rahbarizadeh"], + ["Mohammad J", "Rasaee"], + ["Mehdi", "Forouzandeh"], + ["Abdolamir", "Allameh"], + ["Ramin", "Sarrami"], + ["Habib", "Nasiry"], + ["Majid", "Sadeghizadeh"] ], - "publisher": "Psychiatry research", - "issn": "0165-1781", - "date": "1999-03-22", - "abstract": "There is some evidence that the neurotransmitter serotonin (5-hydroxytryptamine; 5-HT) may be involved in the pathogenesis of seasonal affective disorder (SAD).

Since other familial factors have been proposed to influence the age of onset of HD, we have examined a number of candidate loci. The CAG repeat number on normal chromosomes, the delta2642 polymorphism in the HD gene, and apolipoprotein E genotypes did not affect the age of onset of HD.

Excitotoxicity has been a favored mechanism to explain the cell death in HD, particularly since intrastriatal injection of excitatory amino acids in animals creates HD-like pathology. Accordingly, we investigated the GluR6 kainate receptor. Of the variance in the age of onset of HD that was not accounted for by the CAG repeats, 13% could be attributed to GluR6 genotype variation.

We find that the change in repeat length with paternal transmission is significantly correlated with the change in age at onset between the father and offspring. When expanded triplet repeats of affected parents are separated by median repeat length, we find that the longer paternal and maternal repeats are both more unstable on transmission. However, unlike in paternal transmission, in which longer expanded repeats display greater net expansion than do shorter expanded repeats, in maternal transmission there is no mean change in repeat length for either longer or shorter expanded repeats. We also confirmed the inverse relationship between repeat length and age at onset, the higher frequency of juvenile-onset cases arising from paternal transmission, anticipation as a phenomenon of paternal transmission, and greater expansion of the trinucleotide repeat with paternal transmission. Stepwise multiple regression indicates that, in addition to repeat length of offspring, age at onset of affected parent and sex of affected parent contribute significantly to the variance in age at onset of the offspring. Thus, in addition to triplet repeat length, other factors, which could act as environmental factors, genetic factors, or both, contribute to age at onset.

In contrast, on HD chromosomes, changes in CAG size occur in approximately 70% of meioses on HD chromosomes, with expansions accounting for 73% of these changes.

More recently, EBV has been associated with Ki-1-positive anaplastic large cell lymphoma (ALCL), a recently described NHL that shares with HD expression of the CD30 antigen Ki-1. Because EBV has been shown to induce Ki-1 expression in vitro, and ALCL has been diagnosed in patients with prior or concurrent HD or NHL, it has been proposed that EBV may mediate progression of a \"primary\" lymphoma to a \"secondary\" ALCL. We report a case in which an AIDS-associated, Ki-1-negative, large-cell immunoblastic lymphoma progressed to a Ki-1 positive ALCL. Analysis of the immunoglobulin heavy chain locus revealed a clonal relationship between these morphologically and immunophenotypically distinct tumors. Although EBV was absent from the original large-cell immunoblastic lymphoma as assessed by in situ hybridization for EBV-encoded small RNA1 (EBER1), polymerase chain reaction for EBNA-1, immunocytochemistry for latent membrane protein 1, and Southern blot hybridization for EBV terminal repeat sequences, all for techniques confirmed the presence of EBV in the secondary ALCL. Moreover, analysis of EBV terminal repeat sequences indicated that the ALCL resulted from expansion of a single EBV-infected clone.

We then studied CAG and CCG repeat lengths in the HD gene on 896 control chromosomes from different ancestries to determine whether the markedly reduced frequency of HD in Finland, Japan, China and African Blacks is associated with an altered frequency of DNA haplotypes and subsequently lower CAG lengths on control chromosomes compared to populations of Western European descent. The results show a highly significant inverse relationship between CAG and CCG repeat lengths. In populations with lowered prevalence rates of HD, CAG repeat lengths are smaller and the distribution of CCG alleles is markedly different from Western European populations.

The present study aimed to investigate the prevalence, clinical spectrum and brain MRI characteristics of NIID in adult-onset nonvascular leukoencephalopathies and assess the diagnostic performance of neuroimaging features. One hundred and sixty-one unrelated Taiwanese patients with genetically undetermined nonvascular leukoencephalopathies were screened for the NOTCH2NLC GGC repeat expansions using fragment analysis, repeat-primed PCR, Southern blot analysis and/or nanopore sequencing with Cas9-mediated enrichment. Among them, 32 (19.9%) patients had an expanded NOTCH2NLC allele and were diagnosed with NIID. We enrolled another two affected family members from one patient for further analysis. The size of the expanded NOTCH2NLC GGC repeats in the 34 patients ranged from 73 to 323 repeats. Skin biopsies from five patients all showed eosinophilic, p62-positive intranuclear inclusions in the sweat gland cells and dermal adipocytes. Among the 34 NIID patients presenting with nonvascular leukoencephalopathies, the median age at symptom onset was 61 years (range, 41-78 years) and the initial presentations included cognitive decline (44.1%; 15/34), acute encephalitis-like episodes (32.4%; 11/34), limb weakness (11.8%; 4/34) and parkinsonism (11.8%; 4/34). Cognitive decline (64.7%; 22/34) and acute encephalitis-like episodes (55.9%; 19/34) were also the most common overall manifestations. Two-thirds of the patients had either bladder dysfunction or visual disturbance. Comparing the brain MRI features between the NIID patients and individuals with other undetermined leukoencephalopathies, corticomedullary junction curvilinear lesions on diffusion weighted images were the best biomarkers for diagnosing NIID with high specificity (98.4%) and sensitivity (88.2%). However, this diffusion weighted imaging abnormality was absent in 11.8% of the NIID patients. When only fluid-attenuated inversion recovery images were available, the presence of white matter hyperintensity lesions either in the paravermis or middle cerebellar peduncles also favoured the diagnosis of NIID with a specificity of 85.3% and sensitivity of 76.5%. Among the MRI scans of 10 patients, performed within 5 days of the onset of acute encephalitis-like episodes, five showed cortical hyperintense lesions on diffusion weighted images and two revealed focal brain oedema. In conclusion, NIID accounts for 19.9% (32/161) of patients with adult-onset genetically undiagnosed nonvascular leukoencephalopathies in Taiwan. Half of the NIID patients developed encephalitis-like episodes with restricted diffusion in the cortical regions on diffusion weighted images at the acute stage.

While Galectin-3 (Gal-3) recognition of TF has been well-documented at both the cellular and molecular level, Galectin-1 (Gal-1) recognition of TF has only truly been alluded to in cell-based platforms. Immunohistochemical analyses have purported Gal-1 binding to TF on MUC1 at the cell surface, however binding at the molecular level was inconclusive.

In this study we have developed a method for large-scale expression of Gal-1 and its histidine-tagged analog for use in binding studies by isothermal titration calorimetry (ITC) and development of an analytical method based on AlphaScreen technology to screen for Gal-1 inhibitors.

Since the overall survival rate of pancreatic cancer patients has remained low for several decades, novel therapeutic approaches are highly needed. Intestinal mucin has been known to be affected by dietary threonine supply since de novo synthesis of mucin proteins is sensitive to luminal threonine concentration. However, it is unknown whether biosynthesis of MUC1 is regulated by threonine in human cancers. In this study, data provided suggests that threonine starvation reduces the level of MUC1 and inhibits the migration of MUC1-expressing pancreatic cancer cells. Interestingly, knockdown of threonyl-tRNA synthetase (TRS), an enzyme that catalyzes the ligation of threonine to its cognate tRNA, also suppresses MUC1 levels but not mRNA levels. The inhibitors of TRS decrease the level of MUC1 protein and prohibit the migration of MUC1-expressing pancreatic cancer cells. In addition, a positive correlation between TRS and MUC1 levels is observed in human pancreatic cancer cells. Concurrent with these results, the bioinformatics data indicate that co-expression of both TRS and MUC1 is correlated with the poor survival of pancreatic cancer patients.

Around 30,000 to 41,599 SVs were detected per sample. High-consequence tumour suppressor gene SVs were identified in EPHA3, CASP8, DMBT1, ZFHX3, and IRF5 gene. Common copy number tumour suppressor gene loss observed in RNH1, H19, CDKN1C, and others, suggesting their role in NPC carcinogenesis. Copy number gains were found in potential oncogenes such as Y RNA, LTO1, and FADD. Pathogenic short tandem repeats (STRs) in PABPN1 and RFC1 were identified in three samples, presenting a novel association with NPC. NPC sample which exhibited significant genomic instability had the shortest survival, potentially linked to multiple defective DNA repair genes. This study utilized long-read sequencing to identify a complex spectrum of genetic alterations, including numerous SVs and potentially pathogenic STRs, in Indonesian NPC. Extensive DNA repair gene defects, primarily complex SVs detectable by long reads, were observed and highly possibly associated with poor survival. These findings underscore the potential of long-read sequencing for uncovering clinically relevant mutations in NPC.", + "language": "en", + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:40594369" }, { - "id": "pmid:23770070", + "id": "pmid:40552959", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/23770070", - "title": "Identification of mucins by using a method involving a combination of on-membrane chemical deglycosylation and immunostaining.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/40552959", + "title": "Polyalanine Expansion in PABPN1 Alters the Structure and Dynamics of Its Nuclear Aggregates in Differentiated Muscle Cells.", "type": "article-journal", - "doi": "10.1016/j.jim.2013.06.002", + "doi": "10.1096/fj.202501097r", "authors": [ - ["Yu-ki", "Matsuno"], - ["Weijie", "Dong"], - ["Seiya", "Yokoyama"], - ["Suguru", "Yonezawa"], - ["Hisashi", "Narimatsu"], - ["Akihiko", "Kameyama"] + ["Sander D", "Mallon"], + ["Erik", "Bos"], + ["Vahid", "Sheikhhassani"], + ["Milad", "Shademan"], + ["Lenard M", "Voortman"], + ["Alireza", "Mashaghi"], + ["Thomas H", "Sharp"], + ["Vered", "Raz"] ], - "publisher": "Journal of immunological methods", - "issn": "1872-7905", - "date": "2013-06-14", - "abstract": "The characterization of mucins is critically important for gaining insights into the molecular pathology of diseases, including cancers, as well as for the discovery of biomarkers for disease diagnosis.

We demonstrate that these differences were more pronounced in differentiated muscle cells compared to proliferating cells.

The gene that codes for this molecule is composed of a polymorphic tandem repeat of 60 nucleotides. Our objective was to determine if MUC-1 genetic polymorphism is associated with implantation failure in patients with a history of recurrent abortion. The study was conducted on 10 women aged 25 to 35 years with no history of successful pregnancy and with a diagnosis of infertility.

Mucins act as lubricants, protectants, and mediators of signal transduction. The majority of the O-glycosylation sites on the transmembrane mucin MUC1 are found in a highly polymorphic core region containing a variable number of tandem repeats (VNTR). MUC1 alleles can be divided into size classes that contain small (30-45) or large (60-90) numbers of repeats. Although at least 12 splice variants of MUC1 have been found in other tissues, no splice variants have been reported in human ocular surface tissues. We have used RT-PCR to identify MUC1 splice variants that were then confirmed by sequencing. We here report the presence in some samples of human cornea, conjunctiva, and lacrimal gland of MUC1/B which features canonical splicing between exons 1 and 2 and MUC1/A, a transcript that retains 27bp from the 3' end of intron 1 and is predicted to add 9 amino acids to the MUC1 sequence upstream of the tandem repeat region. Cornea and conjunctiva both contain the MUC1/SEC splice variant that lacks the transmembrane domain and, therefore, results in a soluble, secreted form of MUC1. Cornea and conjunctiva also contain MUC1/Y and MUC1/Z(X) variants that lack the tandem repeat region. Cornea, conjunctiva, and lacrimal gland also contain a previously undescribed MUC1 variant transcript, termed MUC1/YI, that retains 99bp from the 5' end and 27bp from the 3' end of the first intron, resulting in a frame shift and premature stop codon. This transcript is predicted to produce a novel 27 amino acid peptide after signal peptidase cleavage. Analysis of brush cytology samples revealed that the percentage of dry eye patients expressing the MUC1/A variant in the conjunctival epithelium is lower than in normal control donors. Western blotting confirmed that MUC1/A is associated with alleles containing the large size class of tandem repeats. Therefore, we propose that one factor in susceptibility to dry eye disease may be the lengths of the MUC1 VNTR in conjunctival epithelium based on the rationale that longer VNTR provide better lubrication and greater protection of the ocular surface against inflammation.", + "publisher": "Biochemical and biophysical research communications", + "issn": "0006-291X", + "date": "2005-12-21", + "abstract": "Oculopharyngeal muscular dystrophy (OPMD) is an adult-onset dominant genetic disease caused by the expansion of a GCG trinucleotide repeat that encodes the polyalanine tract at the N-terminus of the nuclear poly(A)-binding protein (PABPN1).

At present, there is no specific treatment to reduce the aggregate burden in patients. However, in cell culture models of OPMD, reduction of protein aggregation can be achieved by ectopic expression of HSP70. As gene transfer may not be the most effective means to elevate HSP70 levels, we tested four pharmacological agents for their ability to induce HSP70, recruit both HSP70 and HSC70 into the cell nucleus and reduce mutant PABPN1 aggregation in a HeLa cell culture model. We show here that exposure to moderate levels of ZnSO4, 8-hydroxyquinoline, ibuprofen and indomethacin produced a robust stress response resulting in the induction of HSP70 in HeLa cells expressing the mutant PABPN1 as a green fluorescent protein (GFP) fusion protein. Both HSP70 and the constitutive chaperone HSC70 localized in the nucleus of cells treated with any one of the four agents.

The key to eliciting potent immunity to tumor MUC1 may be in generating MUC1-specific T-helper cell responses, which, to date, have not been reported in cancer patients. We have recently demonstrated that a synthetic vaccine representing five copies of the MUC1 tandem repeat peptide can be used to prime MUC1-specific human CD4+ T cells in vitro. Here, we extend these studies to test the immunogenicity and safety of the tandem repeat peptide in the chimpanzee, which has the identical MUC1 tandem repeat sequence to the human. To promote induction of Th1-type responses, we used the novel adjuvant LeIF, a Leishmania-derived protein that is known to stimulate human peripheral blood mononuclear cells (PBMCs) and antigen-presenting cells, to produce a Th1-type cytokine profile. We found that MUC1 tandem repeat peptide administered with LeIF elicited positive, albeit transient, proliferative T-cell responses to MUC1 in the PBMCs from four of four chimpanzees. Immunization induced MUC1-specific IFN-gamma but not interleukin 4 expression in CD4+ T cells from PBMCs and draining lymph nodes. MUC1-specific CTLs were also generated that did not induce detectable autoimmune dysfunction during the 1 year of observation.

Variant Hirschsprung's disease is a rarer disorder that does not meet the diagnostic criteria of Hirschsprung's disease, although severe functional bowel obstruction persists. We present a case of an extremely low birth weight infant with congenital central hypoventilation syndrome and variant Hirschsprung's disease. A male infant who was diagnosed to have fetal growth restriction and polyhydramnios was delivered by emergency cesarean section at 30 weeks and 3 days of gestational age due to non-reassuring fetal status. The birth weight was 979\u202fg, and intensive care was started immediately following delivery. The patient exhibited refractory apnea and was diagnosed with congenital central hypoventilation syndrome by genetic testing of the paired-like homeobox 2B gene. The patient also exhibited refractory functional bowel obstruction and was diagnosed to have variant Hirschsprung's disease through pathological examination of his intestinal specimens. The patient grew slowly but surely with intensive care including mechanical ventilation and parenteral nutrition. However, the patient repeatedly suffered from sepsis and died of fungemia at 197 days of age.

Elongation of the alanine stretch in PHOX2B leads to a protein with altered DNA binding, transcriptional activity, and nuclear localization and the possible formation of cytoplasmic aggregates; furthermore, the findings of various studies support the idea that CCHS is not due to a pure loss of function mechanism but also involves a dominant negative effect and/or toxic gain of function for PHOX2B mutations. Because PHOX2B forms homodimers and heterodimers with its paralogue PHOX2A in vitro, we tested the hypothesis that the dominant negative effects of the mutated proteins are due to non-functional interactions with the wild-type protein or PHOX2A using a co-immunoprecipitation assay and the mammalian two-hybrid system. Our findings show that PHOX2B forms homodimers and heterodimerizes weakly with mutated proteins, exclude the direct involvement of the polyalanine tract in dimer formation, and indicate that mutated proteins retain partial ability to form heterodimers with PHOX2A. Moreover, in this study, we investigated the effects of the longest polyalanine expansions on the homeodomain-mediated nuclear import, and our data clearly show that the expanded C terminus interferes with this process.

The rat MUC5 was cloned by the RT-PCR using motifs conserved in the secretory mucins, MUC2 and MUC5. The rat cDNA revealed a high degree of sequence similarity to human MUC5 (73% at the amino acid level). Alignments with three other secretory mucins (human MUC5, human MUC2, rat MUC2), indicated a conservation of the cysteines and of the octapeptide motifs, but a lack of conservation of a short tandem repeat sequence that is found only in the human MUC5. Northern analysis of MUC1 and MUC5 indicated a specific tissue-restricted pattern of expression. Surprisingly, rat MUC5 exhibited a monodisperse signal, a characteristic that is unusual for most secretory mucins, including the human MUC5. Expression of MUC1 and MUC5 correlated with mucous differentiation. Both genes were expressed at undetectable or very low levels in undifferentiated cultures, but both mucins became strongly expressed during mucous differentiation. Furthermore, neither mucin gene was expressed in retinoid-deficient cultures that undergo squamous instead of mucous differentiation.

Elective abortion was performed at 21.5 weeks gestation. Testing of abortus tissue confirmed amniocentesis testing. The PHOX2B 20/27 expansion was not observed in a paternal sperm sample.

The method uses the 3' non-tandem repeat mucin cDNA sequences, as they were shown to have a single-size transcript when amplified by the polymerase chain reaction, consistent with a one-to-one relationship with the mRNA molecule. The 3' non-tandem repeat cDNA sequences were cloned and transcribed in vitro to prepare complementary RNA (cRNA) standards. By comparison to a cRNA standard curve, mucin gene expression was evaluated in colon adenocarcinoma, pancreatic adenocarcinoma, and transformed respiratory epithelial cells and in nasal polyp tissue by slot blot analysis. CFPAC-1, a pancreatic adenocarcinoma cell line, expressed the highest MUC1 transcript levels. Colon adenocarcinoma cell lines varied in MUC2 expression levels, and one colon adenocarcinoma cell line, HT-29, had higher levels of MUC5 than MUC2. Nasal polyp tissue expressed more MUC5 mRNA than MUC1 or MUC2 mRNA. This mucin mRNA slot blot method provides a quantitative method for investigating the regulation of mucin gene expression in health and disease.", + "publisher": "Journal of human genetics", + "issn": "1435-232X", + "date": "2012-03-22", + "abstract": "Congenital central hypoventilation syndrome (CCHS; MIM 209880) is caused mostly by dominant alanine expansion (most prevalent is 7-alanine expansion) mutations in PHOX2B.

To deepen into the molecular mechanisms mediating the effects of PHOX2B polyalanine expansions, we have set up experiments aimed at assessing the fate of cells characterized by PHOX2B polyalanine aggregates. In particular, we have observed that activation of the heat shock response by the drug geldanamycin is efficient both in preventing formation and in inducing clearance of PHOX2B pre-formed polyalanine aggregates in COS-7 cells expressing PHOX2B-GFP fused proteins, and ultimately also in rescuing the PHOX2B ability to transactivate the Dopamine-beta-Hydroxilase promoter. In addition, we have demonstrated elimination of PHOX2B mutant proteins by the proteasome and autophagy, two cellular mechanisms already been involved in the clearance of proteins containing expanded polyglutamine and polyalanine tracts. Moreover, our data suggest that geldanamycin effects on PHOX2B aggregates may be also mediated by the proteasome pathway.

Recognized drug-related side effects are, for example, nausea, fatigue, lactic acidosis, neuropathy, lipodystrophy, and myopathy. Because not all patients experience these side effects, genetic factors could be involved. It is believed that the main toxicity of nucleoside analog drugs is due to a decrease in mitochondrial function, possibly by inhibition of mitochondrial DNA (mtDNA) replication. mtDNA is replicated by a multienzyme complex, the main component of which is the nuclear-encoded DNA polymerase gamma. Presently, the only known variation in the DNA polymerase gamma gene is variation in the number of CAG repeats in the second exon. To investigate whether CAG repeat expansion or mutations in the DNA polymerase gamma (POLG) gene could predispose to peripheral neuropathy or lactic acidosis, we have sequenced part of the second exon of the DNA polymerase gamma gene, containing the CAG repeat, of 59 drug-treated HIV-infected patients, 11 of whom experienced drug-induced neuropathy, and 3 of whom died from lactic acidosis. No correlation was found between numbers of CAG repeats and any of the symptoms. The coding regions of the POLG gene from the three lactic acidosis patients were then completely sequenced, but no mutations were found. In addition, no variation was detected in exons 3, 8, and 19 of seven neuropathy patients and three control subjects without symptoms.

We report here two adult cases of NIID, genetically confirmed, with manifestation of encephalopathy-like symptoms and address the histopathologic findings obtained by brain biopsies, with a focus on \"astrocytic\" intranuclear inclusions (AIIs). Case 1 presented with paroxysmal restlessness, vertigo, or fever and was later involved in severe dementia and tetraparesis. Case 2 presented with forgetfulness and then with paroxysmal fever and headache. In both cases, delimited areas with gadolinium enhancement on magnetic resonance imaging and corresponding hyperperfusion were detected, leading to brain biopsies of the cortex. On histology, Case 1 showed an abnormal lamination, where the thickness of layers was different from usual. Both neurons and astrocytes showed some dysmorphologic features. Notably, astrocytes rather than neurons harbored EIIs. Case 2 showed a cortex, where neurons tended to be arrayed in a columnar fashion. Astrocytes showed some dysmorphologic features. Notably, much more astrocytes than neurons harbored EIIs. By a double-labeling immunofluorescence study for p62/NeuN and p62/glial fibrillary acidic protein, the predominance of AIIs was confirmed in both cases. Considering the physiological functions of astrocytes for the development and maintenance of the cortex, the encephalopathy-like symptoms, dynamic change of cerebral blood flow, and cortical dysmorphology can reasonably be explained by the dysfunction of EII-bearing astrocytes rather than EII-bearing neurons. This study suggests the presence of a subtype of NIID where AIIs rather than \"neuronal\" intranuclear inclusions are likely a key player in the pathogenesis of NIID, particularly in cases with encephalopathy-like symptoms.

Rapid and accurate sequencing of the prion gene PRNP is paramount to human prion disease diagnosis and for animal surveillance programmes. Current methods for PRNP genotyping involve sequencing of small fragments within the protein-coding region. The contribution of variants in the non-coding regions of PRNP including large structural changes is poorly understood. Here, we used long-range PCR and Nanopore sequencing to sequence the full length of PRNP, including its regulatory region, in 25 samples from blood and brain of individuals with inherited or sporadic prion diseases. Nanopore sequencing detected the same variants as identified by Sanger sequencing, including repeat expansions/deletions. Nanopore identified additional single-nucleotide variants in the non-coding regions of PRNP, but no novel structural variants were discovered. Finally, we explored somatic mosaicism of PRNP's octapeptide repeat region, which is a hypothetical cause of sporadic prion disease. While we found changes consistent with somatic mutations, we demonstrate that they may have been generated by the PCR. Our study illustrates the accuracy of Nanopore sequencing for rapid and field prion disease diagnosis and highlights the need for single-molecule sequencing methods for the detection of somatic mutations.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:38477063" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:35585119" }, { - "id": "pmid:37975799", + "id": "pmid:21686668", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/37975799", - "title": "GGC expansions in NOTCH2NLC contribute to Parkinson disease and dopaminergic neuron degeneration.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/21686668", + "title": "De novo seven extra repeat expanded mutation in the PRNP gene in an Italian patient with early onset dementia.", "type": "article-journal", - "doi": "10.1111/ene.16145", + "doi": "10.1136/bcr.08.2008.0711", "authors": [ - ["Qiong", "Liu"], - ["Juan", "Chen"], - ["Jin", "Xue"], - ["Xun", "Zhou"], - ["Yun", "Tian"], - ["Qiao", "Xiao"], - ["Wen", "Huang"], - ["Yongcheng", "Pan"], - ["Xiaoxia", "Zhou"], - ["Jian", "Li"], - ["Yuwen", "Zhao"], - ["Hongxu", "Pan"], - ["Yige", "Wang"], - ["Runcheng", "He"], - ["Yaqin", "Xiang"], - ["Tian", "Tu"], - ["Qian", "Xu"], - ["Qiying", "Sun"], - ["Jieqiong", "Tan"], - ["Xinxiang", "Yan"], - ["Jinchen", "Li"], - ["Jifeng", "Guo"], - ["Lu", "Shen"], - ["Ranhui", "Duan"], - ["Beisha", "Tang"], - ["Zhenhua", "Liu"] + ["M", "Cannella"], + ["Tiziana", "Martino"], + ["Maria", "Simonelli"], + ["Andrea", "Ciammola"], + ["Roberto", "Gradini"], + ["Andrea", "Ciarmiello"], + ["Fernando", "Gianfrancesco"], + ["Ferdinando", "Squitieri"] ], - "publisher": "European journal of neurology", - "issn": "1468-1331", - "date": "2023-11-17", - "abstract": "The role of GGC repeat expansions within NOTCH2NLC in Parkinson's disease (PD) and the substantia nigra (SN) dopaminergic neuron remains unclear.

Comparable data have not been derived for mule deer, a species susceptible to the TSE chronic wasting disease (CWD). Initial analysis of the open reading frame (ORF) in exon 3 of the mule deer PRNP gene revealed polymorphisms in all 145 samples analyzed, with 10 potential polymorphic sites.

Analysis of BAC clones containing mule deer PRNP genes revealed a full length functional gene and a processed pseudogene. The pseudogene was characteristic of previously described retroelements, in that it lacks introns and is flanked by repeat sequences. Three alleles of the functional gene were identified, with coding changes only at codons 20 (D/G) and 225 (S/F). Determination of PRNP functional gene alleles from 47 CWD-positive mule deer showed the predominant allele encoded 20D225S (frequency 0.85). When alleles were grouped by coding changes in the functional gene, four of the six possible peptide combinations were identified in infected deer. Three pseudogene alleles with coding changes in exon 3 were identified in the mule deer samples examined.

Within the context of this study, we describe a simple and practical protocol enabling the efficient reprogramming of terminally differentiated adult fibroblasts into integration-free human iPSCs (hiPSCs) using a combination of episomal plasmids with small molecules (SMs). Using this approach, there was a 10-fold increase in reprogramming efficiency over single plasmid vector-based methods. We obtained approximately 100 iPSCs colonies from 1\u2009\u00d7\u200910(5) human adult dermal fibroblasts (HADFs) and achieved approximately 0.1% reprogramming efficiencies. Concurrently, we developed a highly conducive culture system using xeno-free media and human vitronectin. The resulting hiPSCs were free of DNA integration and had completely lost episomal vectors, maintained long-term self-renewal, featured a normal karyotype, expressed pluripotent stem cell markers, and possessed the capability of differentiating into components of all three germ layers in vivo. Finally, we demonstrate that the integration-free hiPSCs could be differentiated into motor neurons under xeno-free culture conditions.

Here, we report an additional recombination hotspot within LCR17pA and LCR17pD, which serve as alternative substrates for nonallelic homologous recombination that results in large (approximately 5 Mb) deletions of 17p11.2, which include the SMS region. Using polymerase-chain-reaction mapping of somatic cell hybrid lines, we refined the breakpoints of six deletions within these LCRs. Sequence analysis of the recombinant junctions revealed that all six strand exchanges occurred within a 524-bp interval, and four of them occurred within an AluSq/x element. This interval represents only 0.5% of the 124-kb stretch of 98.6% sequence identity between LCR17pA and LCR17pD.

The PISCES motif confers pancreatic islet-specific activity and is recognized by an islet-specific transcription factor (PISCES-BP). The consequences on functional activity and on protein binding of the 8-bp repeat sequence in the human insulin promoter was investigated. When fused to a reporter gene and transiently transfected into an insulin-producing islet cell line, the 8-bp repeat decreased basal transcriptional activity of the human insulin promoter (from -366 to +42) whereas the induction of promoter activity by cAMP was unaffected. The isolated rat Ins-E1 element was sufficient to confer basal transcriptional activity to a minimal promoter; the corresponding fragments of the normal and variant human insulin genes (from -329 to -288), however, were not. Using nuclear extracts in an electrophoretic mobility shift assay, it was found that PISCES-BP recognizes rat Ins-E1, but PISCES-BP binding to the corresponding normal and variant human insulin promoter fragments was not detectable and weak, respectively. However, a nuclear protein was found that binds to the variant but not normal human sequence.

This study recruited 26 genetically determined CANVAS patients in whom the size of the pathological intronic expansion was measured on both alleles.

According to the median expansion length on one allele, the patients were divided in a longer intronic repeat subgroup and a shorter intronic repeat subgroup.

The present study aimed to investigate the prevalence, clinical spectrum and brain MRI characteristics of NIID in adult-onset nonvascular leukoencephalopathies and assess the diagnostic performance of neuroimaging features. One hundred and sixty-one unrelated Taiwanese patients with genetically undetermined nonvascular leukoencephalopathies were screened for the NOTCH2NLC GGC repeat expansions using fragment analysis, repeat-primed PCR, Southern blot analysis and/or nanopore sequencing with Cas9-mediated enrichment. Among them, 32 (19.9%) patients had an expanded NOTCH2NLC allele and were diagnosed with NIID. We enrolled another two affected family members from one patient for further analysis. The size of the expanded NOTCH2NLC GGC repeats in the 34 patients ranged from 73 to 323 repeats. Skin biopsies from five patients all showed eosinophilic, p62-positive intranuclear inclusions in the sweat gland cells and dermal adipocytes. Among the 34 NIID patients presenting with nonvascular leukoencephalopathies, the median age at symptom onset was 61 years (range, 41-78 years) and the initial presentations included cognitive decline (44.1%; 15/34), acute encephalitis-like episodes (32.4%; 11/34), limb weakness (11.8%; 4/34) and parkinsonism (11.8%; 4/34). Cognitive decline (64.7%; 22/34) and acute encephalitis-like episodes (55.9%; 19/34) were also the most common overall manifestations. Two-thirds of the patients had either bladder dysfunction or visual disturbance. Comparing the brain MRI features between the NIID patients and individuals with other undetermined leukoencephalopathies, corticomedullary junction curvilinear lesions on diffusion weighted images were the best biomarkers for diagnosing NIID with high specificity (98.4%) and sensitivity (88.2%). However, this diffusion weighted imaging abnormality was absent in 11.8% of the NIID patients. When only fluid-attenuated inversion recovery images were available, the presence of white matter hyperintensity lesions either in the paravermis or middle cerebellar peduncles also favoured the diagnosis of NIID with a specificity of 85.3% and sensitivity of 76.5%. Among the MRI scans of 10 patients, performed within 5 days of the onset of acute encephalitis-like episodes, five showed cortical hyperintense lesions on diffusion weighted images and two revealed focal brain oedema. In conclusion, NIID accounts for 19.9% (32/161) of patients with adult-onset genetically undiagnosed nonvascular leukoencephalopathies in Taiwan. Half of the NIID patients developed encephalitis-like episodes with restricted diffusion in the cortical regions on diffusion weighted images at the acute stage. Corticomedullary junction hyperintense lesions, white matter hyperintensities in the paravermis or middle cerebellar peduncles, bladder dysfunction and visual disturbance are useful hints to diagnosing NIID.", + "publisher": "Clinical neurophysiology : official journal of the International Federation of Clinical Neurophysiology", + "issn": "1872-8952", + "date": "2025-04-05", + "abstract": "", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:35411397" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:40204545" }, { - "id": "pmid:35147270", + "id": "pmid:39721397", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/35147270", - "title": "The role of NOTCH2NLC in Parkinson's disease: A clinical, neuroimaging, and pathological study.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/39721397", + "title": "Spectrum disorder of RFC1 expansions/CANVAS: Clinical and electrophysiological characterization of a group of 31 patients.", "type": "article-journal", - "doi": "10.1111/ene.15283", + "doi": "10.1016/j.clinph.2024.12.007", "authors": [ - ["Peng", "Liu"], - ["Dehao", "Yang"], - ["Fan", "Zhang"], - ["Shuqi", "Chen"], - ["Fei", "Xie"], - ["Yong", "Luo"], - ["Haotian", "Wang"], - ["Yueting", "Chen"], - ["Zhiru", "Lin"], - ["Lebo", "Wang"], - ["Xinhui", "Chen"], - ["Bo", "Wang"], - ["Sheng", "Wu"], - ["Zhiyuan", "Ouyang"], - ["Zhidong", "Cen"], - ["Wei", "Luo"] + ["Elena", "Lainez"], + ["Daniel", "S\u00e1nchez-Tejerina"], + ["Paula", "Fern\u00e1ndez Alvarez"], + ["Margarida", "Gratac\u00f2s-Vi\u00f1ola"], + ["Jos\u00e9 Luis", "Seoane"], + ["Daniela Isabel", "Santa-Cruz"], + ["Lena", "Verdaguer"], + ["Ra\u00fal", "Juntas"], + ["Arnau", "Llaurad\u00f3"], + ["Javier", "Sotoca"], + ["Maria", "Salvado"], + ["Elena", "Garc\u00eda Arumi"], + ["N\u00faria", "Raguer"] ], - "publisher": "European journal of neurology", - "issn": "1468-1331", - "date": "2022-03-03", - "abstract": "Recently, the pathogenic and intermediate GGC repeat expansion in NOTCH2NLC was detected in Parkinson's disease (PD).

We investigated the role of the repeat size in influencing clinical variables in RFC1 disease. We also assessed the presence and role of meiotic and somatic instability of the repeat. In this study, we identified 553 patients carrying biallelic RFC1 expansions and measured the repeat expansion size in 392 cases. Pearson's coefficient was calculated to assess the correlation between the repeat size and age at disease onset. A Cox model with robust cluster standard errors was adopted to describe the effect of repeat size on age at disease onset, on age at onset of each individual symptoms, and on disease progression. A quasi-Poisson regression model was used to analyse the relationship between phenotype and repeat size. We performed multivariate linear regression to assess the association of the repeat size with the degree of cerebellar atrophy. Meiotic stability was assessed by Southern blotting on first-degree relatives of 27 probands. Finally, somatic instability was investigated by optical genome mapping on cerebellar and frontal cortex and unaffected peripheral tissue from four post-mortem cases. A larger repeat size of both smaller and larger allele was associated with an earlier age at neurological onset [smaller allele hazard ratio (HR) = 2.06, P < 0.001; larger allele HR = 1.53, P < 0.001] and with a higher hazard of developing disabling symptoms, such as dysarthria or dysphagia (smaller allele HR = 3.40, P < 0.001; larger allele HR = 1.71, P = 0.002) or loss of independent walking (smaller allele HR = 2.78, P < 0.001; larger allele HR = 1.60; P < 0.001) earlier in disease course.

CANVAS presents enigmatic puzzles: The pathogenic path for CANVAS neither is known nor is it understood why some, but not all expanded, motifs are pathogenic. The most common pathogenic repeat is (AAGGG)n\u2022(CCCTT)n, whereas (AAAAG)n\u2022(CTTTT)n is the most common nonpathogenic motif. While both intronic motifs can be expanded and transcribed, only r(AAGGG)n is retained in the mutant RFC1 transcript. We show that only the pathogenic forms unusual nucleic acid structures. Specifically, DNA and RNA of the pathogenic d(AAGGG)4 and r(AAGGG)4 form G-quadruplexes in potassium solution. Nonpathogenic repeats did not form G-quadruplexes. Triple-stranded structures are formed by the pathogenic motifs but not by the nonpathogenic motifs.

Despite advances in treatment, patients with advanced NPC face poor outcomes. Examining the NPC mutational landscape is crucial for understanding its biology and enable potential new therapeutic strategy. To characterize the landscape of single nucleotide variants (SNVs), structural variants (SVs), copy number variations (CNVs), and short tandem repeats (STRs) in locally advanced to advanced NPC within an Indonesian cohort using long-read sequencing. Six fresh-frozen nasopharyngeal biopsy samples were collected from the NPC biobank. DNA was extracted and sequenced using Oxford Nanopore's Promethion 2 Solo long-read sequencer. Structural and small variants were identified and annotated. The SNVs, SVs, and CNVs were categorized based on predicted effects, and key findings were validated using external RNA-seq data. Copy number loss genes were checked against the Tumour Suppressor Gene database (TSGene v2.0). Genetic findings were correlated with patient clinical histories. Approximately 4.4 to 5.1\u00a0million SNVs were identified per sample, with 0.023% categorized as high consequence. Notable tumour suppressor genes, such as LIMD1 and CNDP2, were frequently mutated. Around 30,000 to 41,599 SVs were detected per sample. High-consequence tumour suppressor gene SVs were identified in EPHA3, CASP8, DMBT1, ZFHX3, and IRF5 gene. Common copy number tumour suppressor gene loss observed in RNH1, H19, CDKN1C, and others, suggesting their role in NPC carcinogenesis. Copy number gains were found in potential oncogenes such as Y RNA, LTO1, and FADD. Pathogenic short tandem repeats (STRs) in PABPN1 and RFC1 were identified in three samples, presenting a novel association with NPC. NPC sample which exhibited significant genomic instability had the shortest survival, potentially linked to multiple defective DNA repair genes. This study utilized long-read sequencing to identify a complex spectrum of genetic alterations, including numerous SVs and potentially pathogenic STRs, in Indonesian NPC.

In concurrence with severe muscle degeneration in OPMD, the decline in PABPN1 accelerated in OPMD and was specific to skeletal muscles. Reduced PABPN1 levels (30% to 60%) in muscle cells induced myogenic defects and morphological signatures of cellular aging in proportion to PABPN1 expression levels.

Using electrophoretic analysis of replication intermediates, we found that (CGG)(n) x (CCG)(n) repeats significantly attenuate replication fork progression. Replication inhibition for this sequence becomes evident at as few as approximately 10 repeats and reaches a maximal level at 30 to 40 repeats.

The propensity of trinucleotide repeats to expand was evaluated in a parallel genetic study. In wild-type cells, expansions of (CGG)(25) x (CCG)(25) and (CAG)(25) x (CTG)(25) repeat tracts occurred with similar low rates. A mutation in the large subunit of the replicative replication factor C complex (rfc1-1) increased the expansion rate for the (CGG)(25) repeat approximately 50-fold but had a much smaller effect on the expansion of the (CTG)(25) repeat.

Intranuclear inclusions consisting predominantly of PABPN1 have been recognized as a pathological hallmark of the genetic disorder. To elucidate the molecular events that lead to disease, recombinant PABPN1, and N-terminal fragments of the protein with varying poly-L-alanine stretches were analyzed. As the full-length protein displayed a strong tendency to aggregate into amorphous deposits, soluble N-terminal fragments were also studied. Expansion of the poly-L-alanine sequence to the maximal length observed in OPMD patients led to an increase of alpha-helical structure. Upon prolonged incubation the protein was found in fibrils that showed all characteristics of amyloid-like fibers. The lag-phase of fibril formation could be reduced by seeding. Structural analysis of the fibrils indicated antiparallel beta-sheets.", - "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:14627730" -}, -{ - "id": "pmid:12673802", - "manubot_success": false, - "link": "https://pubmed.ncbi.nlm.nih.gov/12673802", - "note": "WARNING: Manubot could not generate citation: Command '['manubot', 'cite', 'pmid:12673802']' timed out after 3 seconds" + "publisher": "Muscle & nerve", + "issn": "1097-4598", + "date": "2024-07-23", + "abstract": "Oculopharyngodistal myopathy type 4 (OPDM4) arises from a CGG repeat expansion in the 5' UTR of the RILPL1 gene.

However, the mechanisms underlying the mechanotransduction are not fully understood. Polycystin-1 (PC1) is a promising candidate among proteins that may play a role in the process as it has been shown to function as a flow sensor in renal epithelium and it is known to be important for skeletal development. To investigate whether PC1 is involved in mechanotransduction in skeletal tissues, mice with a conditional deficiency for PC1 in neural crest cells, osteoblasts or chondrocytes were subjected to midpalatal suture expansion. Dynamic bone labeling revealed that new bone formation in response to expansion was significantly reduced in Wnt1Cre;Pkd1 mice, as the suture area containing new bone was 14.0+/-3.4% in mutant mice versus 65.0+/-3.8% in control mice at 2 weeks (p<0.001). In contrast, stress-induced new bone formation was not affected in OsxCre;Pkd1 mice. The increase in cell proliferation and differentiation into osteoblasts, seen in wild-type mice 1 day after force delivery, was not observed until 14 days in Wnt1Cre;Pkd1 mice. TUNEL labeling showed a significant increase in apoptotic suture cells at days 1 and 3 (from 7.0+/-0.5% to 13.5+/-1.4% at day 1 and from 4.6+/-1.1% to 10.5+/-1.7% at day 3, p<0.05). Abnormal ossification of nasal cartilage of Wnt1Cre;Pkd1 mice was accelerated upon suture expansion. Such ossification was also observed, but to a lesser extent in Col2a1-ERCre;Pkd1 mice. Transcript levels of Runx2 and MMP13 were significantly increased in the nasal cartilage of Wnt1Cre;Pkd1 mice compared to controls (p<0.05 and p<0.001, respectively), and in mutant mice with expansion versus without expansion (p<0.05 and p<0.001, respectively). Lack of PC1 in chondroprogenitor cells also resulted in increased cell apoptosis and an altered arrangement of chondrocytes in nasal cartilage. These results indicate that PC1 plays a critical role in the response of osteochondroprogenitor cells to the mechanical tissue stress induced by midpalatal suture expansion. They also suggest that the combination of an in vivo mechanical model, such as midpalatal suture expansion, with conditional deficiency for proteins that play a role in mechanotransduction, represents a powerful experimental strategy to explore underlying mechanisms.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:11712939" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:19264154" }, { - "id": "pmid:11087766", + "id": "pmid:38467733", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/11087766", - "title": "Oculopharyngeal MD among Bukhara Jews is due to a founder (GCG)9 mutation in the PABP2 gene.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/38467733", + "title": "Origin and evolution of pentanucleotide repeat expansions at the familial cortical myoclonic tremor with epilepsy type1 - SAMD12 locus.", "type": "article-journal", - "doi": "10.1212/wnl.55.9.1267", + "doi": "10.1038/s41431-024-01586-y", "authors": [ - ["S C", "Blumen"], - ["A D", "Korczyn"], - ["H", "Lavoie"], - ["S", "Medynski"], - ["J", "Chapman"], - ["A", "Asherov"], - ["P", "Nisipeanu"], - ["R", "Inzelberg"], - ["R L", "Carasso"], - ["J P", "Bouchard"], - ["F M", "Tom\u00e9"], - ["G A", "Rouleau"], - ["B", "Brais"] + ["Xinhui", "Chen"], + ["Fan", "Zhang"], + ["Yihua", "Shi"], + ["Haotian", "Wang"], + ["Miao", "Chen"], + ["Dehao", "Yang"], + ["Lebo", "Wang"], + ["Peng", "Liu"], + ["Fei", "Xie"], + ["Jiawen", "Chen"], + ["Aisi", "Fu"], + ["Ben", "Hu"], + ["Bo", "Wang"], + ["Zhiyuan", "Ouyang"], + ["Sheng", "Wu"], + ["Zhiru", "Lin"], + ["Zhidong", "Cen"], + ["Wei", "Luo"] ], - "publisher": "Neurology", - "issn": "0028-3878", - "date": "2000-11-14", - "abstract": "To determine whether all cases of oculopharyngeal muscular dystrophy (OPMD) among Bukhara Jews share the same founder mutation.", + "publisher": "European journal of human genetics : EJHG", + "issn": "1476-5438", + "date": "2024-03-12", + "abstract": "Familial cortical myoclonic tremor with epilepsy type 1 (FCMTE1) is caused by (TTTTA)exp(TTTCA)exp repeat expansions in SAMD12, while pure (TTTTA)exp is polymorphic.

We examined the subcellular localization of PABP2 in muscle specimens from five patients with OPMD, 14 patients with various neuromuscular disorders, and three normal controls.

Here we dissect the epigenetic regulation and influence of SVAs in cellular models of X-linked dystonia parkinsonism (XDP), a neurodegenerative disorder caused by an SVA insertion at the TAF1 locus. We demonstrate that the KRAB zinc finger protein ZNF91 establishes H3K9me3 and DNA methylation over SVAs, including polymorphic alleles, in human neural progenitor cells.

Variant Hirschsprung's disease is a rarer disorder that does not meet the diagnostic criteria of Hirschsprung's disease, although severe functional bowel obstruction persists. We present a case of an extremely low birth weight infant with congenital central hypoventilation syndrome and variant Hirschsprung's disease. A male infant who was diagnosed to have fetal growth restriction and polyhydramnios was delivered by emergency cesarean section at 30 weeks and 3 days of gestational age due to non-reassuring fetal status. The birth weight was 979\u202fg, and intensive care was started immediately following delivery. The patient exhibited refractory apnea and was diagnosed with congenital central hypoventilation syndrome by genetic testing of the paired-like homeobox 2B gene. The patient also exhibited refractory functional bowel obstruction and was diagnosed to have variant Hirschsprung's disease through pathological examination of his intestinal specimens. The patient grew slowly but surely with intensive care including mechanical ventilation and parenteral nutrition. However, the patient repeatedly suffered from sepsis and died of fungemia at 197 days of age. This is the first congenital central hypoventilation syndrome case that was accompanied with variant Hirschsprung's disease, and the paired-like homeobox 2B mutation detected in this case (NM_003924.3: c.441G\u202f>\u202fC; p.(Gln147His)) is novel.

Polyalanine expansions in the 20-residues region of the C terminus of PHOX2B are the major mutations responsible for CCHS. Elongation of the alanine stretch in PHOX2B leads to a protein with altered DNA binding, transcriptional activity, and nuclear localization and the possible formation of cytoplasmic aggregates; furthermore, the findings of various studies support the idea that CCHS is not due to a pure loss of function mechanism but also involves a dominant negative effect and/or toxic gain of function for PHOX2B mutations. Because PHOX2B forms homodimers and heterodimers with its paralogue PHOX2A in vitro, we tested the hypothesis that the dominant negative effects of the mutated proteins are due to non-functional interactions with the wild-type protein or PHOX2A using a co-immunoprecipitation assay and the mammalian two-hybrid system. Our findings show that PHOX2B forms homodimers and heterodimerizes weakly with mutated proteins, exclude the direct involvement of the polyalanine tract in dimer formation, and indicate that mutated proteins retain partial ability to form heterodimers with PHOX2A. Moreover, in this study, we investigated the effects of the longest polyalanine expansions on the homeodomain-mediated nuclear import, and our data clearly show that the expanded C terminus interferes with this process.

The correlation between length of the alanine expanded tracts and severity of congenital central hypoventilation syndrome respiratory phenotype has been confirmed by length-dependent cytoplasmic PHOX2B retention with formation of aggregates. To deepen into the molecular mechanisms mediating the effects of PHOX2B polyalanine expansions, we have set up experiments aimed at assessing the fate of cells characterized by PHOX2B polyalanine aggregates. In particular, we have observed that activation of the heat shock response by the drug geldanamycin is efficient both in preventing formation and in inducing clearance of PHOX2B pre-formed polyalanine aggregates in COS-7 cells expressing PHOX2B-GFP fused proteins, and ultimately also in rescuing the PHOX2B ability to transactivate the Dopamine-beta-Hydroxilase promoter. In addition, we have demonstrated elimination of PHOX2B mutant proteins by the proteasome and autophagy, two cellular mechanisms already been involved in the clearance of proteins containing expanded polyglutamine and polyalanine tracts. Moreover, our data suggest that geldanamycin effects on PHOX2B aggregates may be also mediated by the proteasome pathway.

Besides interferon-stimulated genes, the SCA17 model and Huntington's mice brain samples showed upregulation of RNA sensors. However, in this improved model interferon pathway activation and apoptosis preceded the formation of large polyglutamine aggregates, suggesting a role for CAG repeat RNA or soluble protein aggregates. A polyglutamine minus mutant of TBP, expressing polyCAG mRNA, was created by site directed mutagenesis of 10 potential start codons. Neither this long CAG embedded mRNA nor short polyCAG RNA could induce interferon pathway genes or cause apoptosis. polyQ-TBP induced the expression of canonical RNA sensors but the downstream transcription factor, IRF3, showed a muted response. We found that expanded CAG repeat RNA is not sufficient to account for the neuronal apoptosis. Neuronal cells sense expanded CAG repeats embedded in messenger RNAs of protein-coding genes. However, polyglutamine containing protein is responsible for the interferon-mediated neuroinflammation and cell death seen in polyglutamine disease. Thus, we delineate the inflammatory role of CAG repeats in the mRNA from the resulting polyglutamine tract in the protein.

Human TBP contains a polymorphic polyglutamine (polyQ) domain in its N terminus and a DNA-binding domain in its highly conserved C terminus. Expansion of the polyQ domain to >42 glutamines typically results in spinocerebellar ataxia type 17 (SCA17), a neurodegenerative disorder that resembles Huntington disease. Our recent studies have demonstrated that polyQ expansion causes abnormal interaction of TBP with the general transcription factor TFIIB and induces neurodegeneration in transgenic SCA17 mice (Friedman, M.

Here we report that polyQ expansion reduces in vitro binding of TBP to DNA and that mutant TBP fragments lacking an intact C-terminal DNA-binding domain are present in transgenic SCA17 mouse brains. polyQ-expanded TBP with a deletion spanning part of the DNA-binding domain does not bind DNA in vitro but forms nuclear aggregates and inhibits TATA-dependent transcription activity in cultured cells.

Thus, we examined the lengths of this polyglutamine repeat in normal unrelated East Anglians, South African Blacks, sub-Saharan Africans mainly from Nigeria, and Asian Indians. We also examined 43 bipolar affective disorder patients and 65 schizophrenic patients. The range of polyglutamine tractlengths that we found in humans was from 26-42 codons.

We have analyzed two CAG repeat containing loci, human SMARCA2 and THAP11, which are expressed in the brain as putative candidates for SCAs, using computational as well as polymorphism scanning approaches. Both loci exhibited features characteristic of genes associated with repeat disorders. These loci are polymorphic with respect to size and interruption pattern in the Indian population. Furthermore, computational analysis of glutamine-stretch embedded domains in the respective proteins predicted these regions to be \"natively unfolded\" beyond a threshold of 40 glutamines. Comparative genome analysis suggested a stabilizing influence of CAA interspersions in repeat tract in THAP11 but not in SMARCA2.

Result of the previous studies have been equivocal and could be attributable to the multicentric study design with different experts examining heterogeneous TS population of various ethnic background. Methods A cross-sectional single center study from Northern India. Fifty nine diagnosed subjects of TS and their parents participated in the study. Parental origin of intact X-chromosome was determined using 12 highly polymorphic short tandem repeats (STR) on X-chromosome. For the evaluation of parent-of-origin effects, typical phenotypic traits including congenital malformations, anthropometry, body composition by dual energy X-ray absorptiometry (DXA) and biochemical profile were compared. Clinical stigmata of TS in all subjects were examined by a single expert. Results The intact X-chromosome was of maternal origin (Xm) in 49.1% subjects while 50.9% had paternal origin (Xp). Skeletal anomalies were more common in Xm group, out of which prevalence of short neck and short fourth metatarsal reached statistical significance (p=0.04 and 0.01 respectively). A strong correlation was observed between subject's baseline height standard deviation score (Ht SDS) and paternal height (r=0.593, p<0.001), maternal height (r=0.564, p<0.001) and mid-parental height (MPH) (r=0.372, p=0.047) in Xp group. This effect was not seen in Xm subjects whose baseline Ht SDS showed no significant correlation with maternal height, paternal height or MPH. No differences were detected between the groups with regard to biochemical profile or body composition. Conclusions We speculate that the differences in skeletal anomalies and height correlations between Xm and Xp groups could be due to the modifying effect of epigenetic signature on short stature homeobox (SHOX) gene of Xm.

In this study, we identified 553 patients carrying biallelic RFC1 expansions and measured the repeat expansion size in 392 cases. Pearson's coefficient was calculated to assess the correlation between the repeat size and age at disease onset. A Cox model with robust cluster standard errors was adopted to describe the effect of repeat size on age at disease onset, on age at onset of each individual symptoms, and on disease progression. A quasi-Poisson regression model was used to analyse the relationship between phenotype and repeat size. We performed multivariate linear regression to assess the association of the repeat size with the degree of cerebellar atrophy. Meiotic stability was assessed by Southern blotting on first-degree relatives of 27 probands. Finally, somatic instability was investigated by optical genome mapping on cerebellar and frontal cortex and unaffected peripheral tissue from four post-mortem cases. A larger repeat size of both smaller and larger allele was associated with an earlier age at neurological onset [smaller allele hazard ratio (HR) = 2.06, P < 0.001; larger allele HR = 1.53, P < 0.001] and with a higher hazard of developing disabling symptoms, such as dysarthria or dysphagia (smaller allele HR = 3.40, P < 0.001; larger allele HR = 1.71, P = 0.002) or loss of independent walking (smaller allele HR = 2.78, P < 0.001; larger allele HR = 1.60; P < 0.001) earlier in disease course.

The most common polymorphism in TS is a unique double (2R) or triple (3R) 28-bp tandem repeat sequence in the enhancer region of the TS gene (TSER). This genetic variation in TSER has been widely investigated and has been implicated as a risk factor for the development of various cancers, including acute lymphoblastic leukemia. It has also been found to influence sensitivity to anti-cancer drugs, such as methotrexate. We evaluated this polymorphism in acute lymphoblastic leukemia patients in the Kashmir population. In order to determine whether a double (2R2R) versus a triple (3R3R) 28-bp tandem repeat in the TSER modulates risk for acute lymphoblastic leukemia, 72 acute lymphoblastic leukemia cases and 144 age and gender matched, unrelated healthy individuals from the Kashmir region of India were evaluated for this polymorphism by PCR and direct sequencing. We found the frequency of the TS 2R allele to be 32.6 and 26.0%, in cases and controls, respectively.

Complete monosomy of X chromosome is responsible for almost 50% of all cases of TS, and mosaicism and X anomaly are detected in the other half. It has already been demonstrated that early diagnosis of these children allows appropriate growth hormone treatment with better final height prognosis and introduction of estrogen at an ideal chronological age. Sixty-four short-stature girls were selected and the clinical data obtained were birth weight and height, weight and height at the first medical visit and target height. Other clinical data including cardiac and renal abnormalities, otitis, Hashimoto thyroiditis, cubitus valgus, short neck, widely separated nipples, and pigmented nevi were obtained from the patients' medical records. The aim of the present study was to evaluate the screening of a group of short-stature girls for TS based on the number of CAG repeats of the androgen receptor gene analyzed by GeneScan software. Patient samples with two alleles (heterozygous) were 49/64 (76.5%) and with one allele (homozygous) were 15/64 (23.5%). A karyotype was determined in 30 patients, 9 homozygous and 21 heterozygous. In the homozygous group, 6/9 were 45,X and 3/9 were 46,XX. In the heterozygous group, 17/21 were 46,XX, and 4/21 were TS patients with mosaicism (45,X/46,XX; 45,X/46XiXq; 46XdelXp). The pattern obtained by GeneScan in two patients with mosaicism in the karyotype was an imbalance between the peak heights of the two alleles, suggesting that this imbalance could be present when there is a mosaicism. The frequency of TS abnormalities (18.7%) did not differ between TS and 46,XX girls. Thus, it is important to accurately assess the incidence of TS in growth-retarded girls, even in the absence of other dysmorphisms. In this study, we diagnosed 6 cases of TS 45,X (9.4%) by molecular analysis, with a 100% sensitivity and 85% specificity. This molecular analysis was able to detect all cases of TS 45,X and the majority of mosaicisms, without the need for more X chromosome markers. In conclusion, determining the number of CAG repeats of the androgen receptor gene analyzed by GeneScan was a fast method with high sensitivity for the detection of TS 45,X, suggesting that it could be interesting as a method for screening a population of growth-retarded girls.", "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:30926972" + "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:18273818" }, { - "id": "pmid:12556494", + "id": "pmid:18267032", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/12556494", - "title": "Replication and expansion of trinucleotide repeats in yeast.", + "link": "https://www.ncbi.nlm.nih.gov/pubmed/18267032", + "title": "ERCC2 2251A>C genetic polymorphism was highly correlated with early relapse in high-risk stage II and stage III colorectal cancer patients: a preliminary study.", "type": "article-journal", - "doi": "10.1128/mcb.23.4.1349-1357.2003", + "doi": "10.1186/1471-2407-8-50", "authors": [ - ["Richard", "Pelletier"], - ["Maria M", "Krasilnikova"], - ["George M", "Samadashwily"], - ["Robert", "Lahue"], - ["Sergei M", "Mirkin"] + ["Ming-Yii", "Huang"], + ["Wei-Yu", "Fang"], + ["Su-Chen", "Lee"], + ["Tian-Lu", "Cheng"], + ["Jaw-Yuan", "Wang"], + ["Shiu-Ru", "Lin"] ], - "publisher": "Molecular and cellular biology", - "issn": "0270-7306", - "date": "2003-02-01", - "abstract": "The mechanisms of trinucleotide repeat expansions, underlying more than a dozen hereditary neurological disorders, are yet to be understood.

Polycystin-1 (PC1) is a promising candidate among proteins that may play a role in the process as it has been shown to function as a flow sensor in renal epithelium and it is known to be important for skeletal development. To investigate whether PC1 is involved in mechanotransduction in skeletal tissues, mice with a conditional deficiency for PC1 in neural crest cells, osteoblasts or chondrocytes were subjected to midpalatal suture expansion. Dynamic bone labeling revealed that new bone formation in response to expansion was significantly reduced in Wnt1Cre;Pkd1 mice, as the suture area containing new bone was 14.0+/-3.4% in mutant mice versus 65.0+/-3.8% in control mice at 2 weeks (p<0.001). In contrast, stress-induced new bone formation was not affected in OsxCre;Pkd1 mice. The increase in cell proliferation and differentiation into osteoblasts, seen in wild-type mice 1 day after force delivery, was not observed until 14 days in Wnt1Cre;Pkd1 mice. TUNEL labeling showed a significant increase in apoptotic suture cells at days 1 and 3 (from 7.0+/-0.5% to 13.5+/-1.4% at day 1 and from 4.6+/-1.1% to 10.5+/-1.7% at day 3, p<0.05).

Lack of PC1 in chondroprogenitor cells also resulted in increased cell apoptosis and an altered arrangement of chondrocytes in nasal cartilage. These results indicate that PC1 plays a critical role in the response of osteochondroprogenitor cells to the mechanical tissue stress induced by midpalatal suture expansion.

The resulting mini-heterochromatin domains attenuate the cis-regulatory impact of SVAs. This is critical for XDP pathology; removal of local heterochromatin severely aggravates the XDP molecular phenotype, resulting in increased TAF1 intron retention and reduced expression.

However, it is not yet elucidated whether the TS genotype is identical in tumor and normal tissue. In this study, we investigated the TS genotype in 151 matched tumor and normal DNA samples isolated from colorectal cancer and adjacent normal tissues by PCR analysis. The results showed that TS genotypes are identical in normal and tumor tissues of homozygous individuals, suggesting that the repeat sequence is stable through carcinogenesis. However, in heterozygous samples, an imbalance between the 2R and 3R alleles in the tumor DNA was frequently observed, suggesting loss of heterozygosity (LOH) at the TS locus. Detailed LOH analysis revealed that 62% (31 of 50) of 2R/3R-heterozygous samples had LOH. Frequent LOH at the TS locus was confirmed by RT-PCR of TS mRNA and microsatellite analysis using the marker D18S59, located on 18p11.3. There was no difference in the expressions of TS mRNA and TS protein between LOH and non-LOH samples.

We queried 6,495 genome sequencing datasets and identified the repeat expansion in seven additional pedigrees. Ultrarare DNA variants near the repeat expansion indicate a common distant founder event in Sweden. Intranuclear ZFHX3-p62-ubiquitin aggregates were abundant in SCA4 basis pontis neurons.

The presence of MND correlates with an earlier age of onset and a worse overall prognosis., The diagnosis of C9orf72-FTD/ALS is established in a proband with suggestive findings and a heterozygous abnormal G4C2 (GGGGCC) hexanucleotide repeat expansion in C9orf72 identified by molecular genetic testing., Treatment of manifestations: Care is often provided by a multidisciplinary team that includes a neurologist, specially trained nurses, pulmonologist, speech therapist, physical therapist, occupational therapist, respiratory therapist, nutritionist, psychologist, social worker, and genetic counselor. Surveillance: Routine follow up by multidisciplinary specialists to monitor neurologic findings, mobility and activities of daily living, psychiatric/behavioral manifestations, nutrition and safety of oral feeding, respiratory and bladder function, and needs of affected individuals and care providers for psychosocial support., C9orf72-FTD/ALS is inherited in an autosomal dominant manner. Almost all individuals diagnosed with C9orf72-FTD/ALS inherited a C9orf72 G4C2 repeat expansion from a heterozygous parent. In most families the heterozygous parent is affected; however, a heterozygous parent may not have clinical manifestations of the disorder due to age-dependent reduced penetrance. Each child of an individual with C9orf72-FTD/ALS has a 50% chance of inheriting the C9orf72 G4C2 repeat expansion. Once a C9orf72 G4C2 repeat expansion has been identified in an affected family member, prenatal and preimplantation genetic testing for the presence of the C9orf72 G4C2 repeat expansion are possible.

While myotonia (involuntary muscle contraction with delayed relaxation) has been reported during the first decade, onset is typically in the third to fourth decade, most commonly with fluctuating or episodic muscle pain that can be debilitating and proximal and axial weakness of the neck flexors and the hip flexors. Subsequently, weakness occurs in the elbow extensors and finger flexors. Facial weakness and weakness of the ankle dorsiflexors are less common. Myotonia rarely causes severe symptoms. In a subset of individuals, calf hypertrophy in combination with brisk reflexes is notable., The diagnosis of DM2 is established in a proband by identification of a heterozygous pathogenic expansion of a CCTG repeat within a complex repeat motif, (TG)n(TCTG)n(CCTG)n in CNBP. The number of CCTG repeats in a pathogenic expansion ranges from approximately 75 to more than 11,000, with a mean of approximately 5,000 repeats. The detection rate of a CNBP CCTG expansion is more than 99% with the combination of routine PCR, Southern blot analysis, and the PCR repeat-primed assay., Treatment of manifestations: Ankle-foot orthoses, wheelchairs, or other assistive devices as needed for weakness; routine physical activity appears to help maintain muscle strength and endurance and to control musculoskeletal pain; medications used with some success in myalgia management include mexilitene, gabapentin, pregabalin, nonsteroidal anti-inflammatory drugs, low-dose thyroid replacement, and tricyclic antidepressants; myotonia rarely requires treatment but mexilitene or lamotrigine may be beneficial in some individuals; removal of cataracts or epiretinal membrane that impair vision; defibrillator placement for those with arrhythmias; hormone substitution therapy for endocrine dysfunction; prokinetic agents may be helpful for gastrointestinal manifestations; cognitive behavioral therapy and modafinil may be helpful for fatigue and daytime sleepiness; vitamin D supplementation for those with deficiency; hearing aids for sensorineural hearing loss. Prevention of secondary complications: Anesthetic risk may be increased and therefore assessment of cardiac and respiratory function before and after surgery are recommended. Prompt treatment of hypothyroidism and vitamin D deficiency to reduce secondary weakness and myotonia. Surveillance: Annual evaluation with neurologist, occupational therapist, and physical therapist; annual ophthalmology evaluation for posterior subcapsular cataracts and epiretinal membranes; annual EKG, echocardiogram, and 24-hour Holter monitoring to detect/monitor cardiac conduction defects and cardiomyopathy; cardiac MRI per cardiologist; annual measurement of fasting serum glucose concentration, glycosylated hemoglobin level, thyroid hormone levels, and vitamin D; serum testosterone and FSH per endocrinologist. Agents/circumstances to avoid: Cholesterol-lowering medications when associated with increased weakness., DM2 is inherited in an autosomal dominant manner.

The mild end of the spectrum includes the phenotypes of asymptomatic increase in serum concentration of creatine phosphokinase (CK) and muscle cramps with myoglobinuria. The severe end of the spectrum includes progressive muscle diseases that are classified as Duchenne/Becker muscular dystrophy when skeletal muscle is primarily affected and as DMD-associated DCM when the heart is primarily affected. Duchenne muscular dystrophy (DMD) usually presents in early childhood with delayed motor milestones including delays in walking independently and standing up from a supine position. Proximal weakness causes a waddling gait and difficulty climbing stairs, running, jumping, and standing up from a squatting position. DMD is rapidly progressive, with affected children being wheelchair dependent by age 12 years. Cardiomyopathy occurs in almost all individuals with DMD after age 18 years. Few survive beyond the third decade, with respiratory complications and progressive cardiomyopathy being common causes of death. Becker muscular dystrophy (BMD) is characterized by later-onset skeletal muscle weakness. With improved diagnostic techniques, it has been recognized that the mild end of the spectrum includes men with onset of symptoms after age 30 years who remain ambulatory even into their 60s. Despite the milder skeletal muscle involvement, heart failure from DCM is a common cause of morbidity and the most common cause of death in BMD. Mean age of death is in the mid-40s. DMD-associated DCM is characterized by left ventricular dilatation and congestive heart failure. Females heterozygous for a DMD pathogenic variant are at increased risk for DCM., The diagnosis of a dystrophinopathy is established in a proband with the characteristic clinical findings and elevated CK concentration and/or by identification of a hemizygous pathogenic variant in DMD on molecular genetic testing in a male and of a heterozygous pathogenic variant in DMD on molecular genetic testing in a female. Females may present with a classic dystrophinopathy or may be asymptomatic carriers., Treatment of manifestations: ACE inhibitors are used with or without beta blockers for cardiomyopathy in both DMD and BMD phenotypes. Congestive heart failure is treated with diuretics and oxygen as needed; cardiac transplantation is offered to persons with severe dilated cardiomyopathy and BMD with limited or no clinical evidence of skeletal muscle disease. Scoliosis is treated with bracing and surgery. Corticosteroid therapy improves muscle strength and function for individuals with DMD between ages five and 15 years; the same treatment is used in BMD, although the efficacy is less clear. Dystrophin restoration therapies have been developed by using synthetic antisense oligonucleotides to restore the reading frame by exon skipping for individuals with specific pathogenic variants in DMD. Prevention of secondary complications: Evaluation by a pulmonologist and cardiologist before surgeries; pneumococcal and influenza immunizations annually; nutrition assessment; physical therapy to promote mobility and prevent contractures; sunshine and a balanced diet rich in vitamin D and calcium to improve bone density and reduce the risk of fractures; weight control to avoid obesity. Surveillance: For males with DMD or BMD: annual or biannual evaluation by a cardiologist beginning at the time of diagnosis; monitoring for scoliosis; baseline pulmonary function testing before wheelchair dependence; frequent evaluations by a pediatric pulmonologist. For heterozygous females: cardiac evaluation at least once after the teenage years. Agents/circumstances to avoid: Botulinum toxin injections; succinylcholine and inhalational anesthetics because of susceptibility to malignant hyperthermia or malignant hyperthermia-like reactions. Evaluation of relatives at risk: Early identification of heterozygous females who are at increased risk for cardiomyopathy and, thus, need routine cardiac surveillance and prompt treatment., The dystrophinopathies are inherited in an X-linked manner. The risk to the sibs of a proband depends on the genetic status of the mother. Heterozygous females have a 50% chance of transmitting the DMD pathogenic variant in each pregnancy. Sons who inherit the pathogenic variant will be affected; daughters who inherit the pathogenic variant are heterozygous and may have a range of clinical manifestations. Males with DMD usually do not reproduce. Males with BMD or DMD-associated DCM may reproduce: all of their daughters are heterozygotes; none of their sons inherit their father's DMD pathogenic variant.

Mild DM1 is characterized by cataract and mild myotonia (sustained muscle contraction); life span is normal. Classic DM1 is characterized by muscle weakness and wasting, myotonia, cataract, and often cardiac conduction abnormalities; adults may become physically disabled and may have a shortened life span. Congenital DM1 is characterized by hypotonia and severe generalized weakness at birth, often with respiratory insufficiency and early death; intellectual disability is common., DM1 is caused by expansion of a CTG trinucleotide repeat in the noncoding region of DMPK.

Median age at onset is 60 years (range: 21-87 years). Nearly 50% of individuals may first experience episodic manifestations including gait and limb ataxia, visual disturbances (diplopia, oscillopsia, and blurring), vertigo and/or dizziness, or dysarthria on average two to four years before the onset of progressive ataxia. Episodic symptoms may persist after the onset of progressive ataxia and may be triggered by alcohol intake and physical activity. Although some individuals eventually require assistance with mobility, use of a wheelchair is less necessary than in other common hereditary spinocerebellar ataxias (e.g., SCA1, SCA2, and SCA3). Dysarthria does not develop in all individuals and often remains mild to moderate. Cerebellar oculomotor signs, including downbeat nystagmus, horizontal gaze-evoked nystagmus, and impaired visual fixation suppression of the vestibuloocular reflex, are common. Unilateral or bilateral vestibular hypofunction and tremor of the upper limbs may occur. Age of onset and clinical presentation can vary within the same family., The diagnosis of GAA-FGF14-related ataxia is established in a symptomatic individual with a compatible phenotype by the identification of a heterozygous (GAA)>300 repeat expansion in intron 1 of FGF14 by molecular genetic testing. Due to reduced penetrance of FGF14 (GAA)250-300 repeat expansions, the diagnosis of GAA-FGF14-related ataxia can also be established in symptomatic individuals with a (GAA)250-300 repeat expansion if their phenotype is compatible, other inherited causes of ataxia have been excluded, and, if possible, familial segregation with the disease is confirmed. Individuals whose phenotype differs significantly from GAA-FGF14-related ataxia should be screened for other causes of inherited ataxias., Treatment of manifestations: There is no cure for GAA-FGF14-related ataxia. The goals of treatment are to improve quality of life, maximize function, and reduce complications. This ideally involves multidisciplinary care by specialists in relevant fields, such as neurologists, ophthalmologists, orthoptists, physical therapists, occupational therapists, speech-language therapists, and psychologists. Preliminary studies have shown promising symptomatic benefits of 4-aminopyridine for ataxic symptoms and downbeat nystagmus. Surveillance: To monitor existing manifestations, the individual's response to supportive care, and the emergence of new manifestations, regularly scheduled follow up by the treating specialists is recommended. Agents/circumstances to avoid: Inform affected individuals that alcohol intake and strenuous physical activity may precipitate episodes of ataxia and may exacerbate incoordination. Avoid medications with known toxicity to the cerebellum and the vestibular system., GAA-FGF14-related ataxia is inherited in an autosomal dominant manner. Most individuals diagnosed with GAA-FGF14-related ataxia inherit an abnormal GAA repeat expansion from a parent who has a high normal-size or likely pathogenic or pathogenic GAA repeat expansion (a parent with an abnormal GAA repeat expansion may or may not have manifestations of GAA-FGF14-related ataxia). Each child of an individual with GAA-FGF14-related ataxia has a 50% chance of inheriting the GAA-FGF14-related allele. The likelihood that offspring who inherit the GAA-FGF14-related allele will have a GAA repeat size in the pathogenic, reduced penetrance, or non-pathogenic range is influenced by intergenerational instability; the size of the GAA repeat is more likely to expand upon maternal transmission and to contract upon paternal transmission. Once a GAA repeat expansion has been identified in an affected family member, predictive testing for at-risk relatives and prenatal and preimplantation genetic testing for GAA-FGF14-related ataxia are possible. However, accurate prediction of future possible clinical manifestations in a fetus found to have an FGF14 GAA repeat expansion is not possible, and the current lack of knowledge regarding somatic instability of the repeat prenatally makes the interpretation of prenatal genetic test results challenging.", + "language": "eng", + "note": "PMID: 38271551\nThis CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: url:https://www.ncbi.nlm.nih.gov/books/NBK599589" }, { - "id": "pmid:36476347", + "id": "genereviews:NBK1126", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/36476347", - "title": "Spinocerebellar ataxia type 17-digenic TBP/STUB1 disease: neuropathologic features of an autopsied patient.", - "type": "article-journal", - "doi": "10.1186/s40478-022-01486-6", + "link": "http://www.ncbi.nlm.nih.gov/books/NBK1126/", + "title": "Oculopharyngeal Muscular Dystrophy", + "type": "chapter", + "doi": "", "authors": [ - ["Rie", "Saito"], - ["Yui", "Tada"], - ["Daisuke", "Oikawa"], - ["Yusuke", "Sato"], - ["Makiko", "Seto"], - ["Akira", "Satoh"], - ["Kodai", "Kume"], - ["Nozomi", "Ueki"], - ["Masahiro", "Nakashima"], - ["Shintaro", "Hayashi"], - ["Yasuko", "Toyoshima"], - ["Fuminori", "Tokunaga"], - ["Hideshi", "Kawakami"], - ["Akiyoshi", "Kakita"] + ["Capucine", "Trollet"], + ["Alexis", "Boulinguiez"], + ["Fanny", "Roth"], + ["Tanya", "Stojkovic"], + ["Gillian", "Butler-Browne"], + ["Teresinha", "Evangelista"], + ["Jean", "Lacau St Guily"], + ["Pascale", "Richard"] ], - "publisher": "Acta neuropathologica communications", - "issn": "2051-5960", - "date": "2022-12-07", - "abstract": "Spinocerebellar ataxia (SCA) type 17-digenic TBP/STUB1 disease (SCA17-DI) has been recently segregated from SCA17, caused by digenic inheritance of two gene mutations - intermediate polyglutamine-encoding CAG/CAA repeat expansions (polyQ) in TBP (TBP", - "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:36476347" + "publisher": "GeneReviews\u00ae", + "issn": "", + "date": "1993-01-01", + "abstract": "Oculopharyngeal muscular dystrophy (OPMD) is characterized by ptosis and dysphagia due to selective involvement of the muscles of the eyelids and pharynx, respectively.

Swallowing difficulties, which determine prognosis, increase the risk for potentially life-threatening aspiration pneumonia and poor nutrition. Other manifestations as the disease progresses can include limitation of upward gaze, tongue atrophy and weakness, chewing difficulties, wet voice, facial muscle weakness, axial muscle weakness, and proximal limb girdle weakness predominantly in lower limbs. Some individuals with severe involvement will eventually need a wheelchair.

The initial treatment for dysphagia is dietary modification; surgical intervention for dysphagia should be considered when symptomatic dysphagia has a significant impact on quality of life. Physical and occupational therapy are encouraged; assistive devices may be necessary to prevent falls and assist with walking and mobility. Neuropsychological support as needed. Surveillance: Routine evaluation of: neuromuscular and oculomotor involvement; dysphagia including nutritional status and diet; respiratory function given the increased risk for both aspiration and nocturnal hypoventilation; and cognitive function including development of psychiatric symptoms., OPMD is inherited in an autosomal dominant manner. The risk to sibs of a proband depends on the genetic status of the parents of the proband: If one parent of a proband is heterozygous for a GCN repeat expansion in PABPN1 (GCN[11_18]+ [10]) and the other parent has two normal alleles (GCN[10]+[10]), the risk to the sibs of inheriting a GCN repeat expansion is 50%. If both parents of the proband are heterozygous for a GCN repeat expansion, sibs have a 25% risk of inheriting two GCN repeat expansions and a 50% risk of inheriting one GCN repeat expansion.

The age of initial recognition of CCHS ranges from neonatal onset (i.e., in the first 30 days of life) to (less commonly) later onset (from 1 month to adulthood). Neonatal-onset CCHS is characterized by apparent hypoventilation with monotonous respiratory rates and shallow breathing either during sleep only or while awake as well as asleep; ANSD including decreased heart rate beat-to-beat variability and sinus pauses; altered temperature regulation; and altered pupillary response to light. Some children have altered development of neural crest-derived structures (i.e., Hirschsprung disease, altered esophageal motility/dysphagia, and severe constipation even in the absence of Hirschsprung disease) and/or tumors of neural crest origin (neuroblastoma, ganglioneuroma, and ganglioneuroblastoma). Neurocognitive delay is variable, and possibly influenced by cyanotic breath holding, prolonged sinus pauses, need for 24-hour/day artificial ventilation, and seizures. Later-onset CCHS is characterized by alveolar hypoventilation during sleep and attenuated manifestations of ANSD., The diagnosis of CCHS is established in a proband with suggestive findings and a heterozygous PHOX2B pathogenic variant identified on molecular genetic testing., Treatment of manifestations: Management by multidisciplinary specialists, including pediatric pulmonology, sleep medicine, cardiology, oncology, ophthalmology, gastroenterology, neurodevelopmental psychology, and neurology, is recommended. The treatment goals for CCHS are to secure the airway and to use chronic artificial ventilatory support at home to compensate for the hypoventilation and the altered/absent ventilatory responses to hypoxemia and hypercarbia. Prolonged transient asystoles that may present as syncope and/or staring spells and are of significant duration (\u22653.0 seconds) may warrant placement of a cardiac pacemaker; abnormal pupillary reactivity may necessitate protective eye wear given the amount of light exposure in daily life from LED lights, and screen time in educational settings, computer-based work environments, and mobile devices. Other findings treated as per standard practice include Hirschsprung disease and other gastrointestinal motility issues; tumors of neural crest origin; and cognitive impairment/delay. Surveillance: Assess every six months for the first three years, then annually thereafter: (1) in a pediatric respiratory physiology laboratory spontaneous breathing awake (in varied age-appropriate activities of daily living during the daytime and before sleep) and asleep, with recording of respiratory inductance plethysmography of the chest and abdomen, hemoglobin saturation with pulse waveform, end-tidal carbon dioxide level with visible waveform, electrocardiogram, blood pressure, cerebral regional blood flow/oxygenation, and appropriate sleep state staging measures; (2) hemoglobin/hematocrit and reticulocyte count for polycythemia; (3) 72-hour Holter recording for abrupt, prolonged asystoles; (4) echocardiogram changes consistent with right ventricular hypertrophy and cor pulmonale; (5) neurocognitive assessment/educational needs; and (6) comprehensive age-appropriate noninvasive autonomic testing. Agents/circumstances to avoid: Swimming and breath-holding contests (risk of asphyxia, death); alcohol (respiratory depression), recreational drugs (varied effects including death), and prescription as well as non-prescription medications/sedatives/anesthetics that could induce respiratory depression. Evaluation of relatives at risk: It is appropriate to clarify the genetic status of parents, sibs, and offspring of an individual with CCHS in order to identify as early as possible family members who would benefit from prompt initiation of treatment, surveillance, and awareness of agents/circumstances to avoid., CCHS is typically inherited in an autosomal dominant manner (CCHS caused by biallelic reduced penetrance PHOX2B pathogenic variants has been reported in two families). The majority of affected individuals have the disorder as the result of a de novo pathogenic variant. Somatic/germline mosaicism is present in 5%-25% of asymptomatic parents. If a parent of the proband is known to be heterozygous for the PHOX2B pathogenic variant identified in the proband, the risk to the sibs of inheriting the pathogenic variant is 50%. Once the PHOX2B pathogenic variant has been identified in an affected family member, prenatal testing for a pregnancy at increased risk and preimplantation genetic testing are possible (because of the high frequency of parental mosaicism in CCHS, a fetus should be considered at risk for CCHS even if the PHOX2B pathogenic variant detected in the proband was not identified in either parent).", + "language": "eng", + "note": "PMID: 20301600\nThis CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: url:https://www.ncbi.nlm.nih.gov/books/NBK1427" }, { - "id": "pmid:35482253", + "id": "genereviews:NBK1513", "manubot_success": true, - "link": "https://www.ncbi.nlm.nih.gov/pubmed/35482253", - "title": "Calpains as novel players in the molecular pathogenesis of spinocerebellar ataxia type 17.", - "type": "article-journal", - "doi": "10.1007/s00018-022-04274-6", + "link": "http://www.ncbi.nlm.nih.gov/books/NBK1513/", + "title": "Cleidocranial Dysplasia Spectrum Disorder", + "type": "chapter", + "doi": "", "authors": [ - ["Jonasz Jeremiasz", "Weber"], - ["Stefanie Cari", "Anger"], - ["Priscila", "Pereira Sena"], - ["Rana Dilara", "Incebacak Eltemur"], - ["Chrisovalantou", "Huridou"], - ["Florian", "Fath"], - ["Caspar", "Gross"], - ["Nicolas", "Casadei"], - ["Olaf", "Riess"], - ["Huu Phuc", "Nguyen"] + ["Keren", "Machol"], + ["Roberto", "Mendoza-Londono"], + ["Brendan", "Lee"] + ], + "publisher": "GeneReviews\u00ae", + "issn": "", + "date": "1993-01-01", + "abstract": "Cleidocranial dysplasia (CCD) spectrum disorder is a skeletal dysplasia that represents a clinical continuum ranging from classic CCD (triad of delayed closure of the cranial sutures, hypoplastic or aplastic clavicles, and dental abnormalities), to mild CCD, to isolated dental anomalies without other skeletal features.

We have therefore developed a screening method consisting of a multiplex PCR followed by fragment analysis. The method detected putative disease-causing insertions and deletions in the proximal repeats of the VNTR, and determined the VNTR-length of each allele. When blindly testing 56 members of the two families with known single-base deletions in the CEL VNTR, the method correctly assessed the mutation carriers. Screening of 241 probands from suspected maturity-onset diabetes of the young (MODY) families negative for mutations in known MODY genes (95 individuals from Denmark and 146 individuals from UK) revealed no deletions in the proximal repeats of the CEL VNTR. However, we found one Danish patient with a short, novel CEL allele containing only three VNTR repeats (normal range 7-23 in healthy controls). This allele co-segregated with diabetes or impaired glucose tolerance in the patient's family as six of seven mutation carriers were affected.

Besides interferon-stimulated genes, the SCA17 model and Huntington's mice brain samples showed upregulation of RNA sensors. However, in this improved model interferon pathway activation and apoptosis preceded the formation of large polyglutamine aggregates, suggesting a role for CAG repeat RNA or soluble protein aggregates. A polyglutamine minus mutant of TBP, expressing polyCAG mRNA, was created by site directed mutagenesis of 10 potential start codons. Neither this long CAG embedded mRNA nor short polyCAG RNA could induce interferon pathway genes or cause apoptosis. polyQ-TBP induced the expression of canonical RNA sensors but the downstream transcription factor, IRF3, showed a muted response. We found that expanded CAG repeat RNA is not sufficient to account for the neuronal apoptosis. Neuronal cells sense expanded CAG repeats embedded in messenger RNAs of protein-coding genes. However, polyglutamine containing protein is responsible for the interferon-mediated neuroinflammation and cell death seen in polyglutamine disease.

To study whether age and/or DNA repair activity have an effect on the somatic stability of CAG repeats, we analyzed variations of the length of naturally polymorphic CAG repeats in the striatum of young and aged WT and ogg1 KO mice. Some multiple and long polymorphic CAG repeats were observed to have variable length in the striatum of aged mice.

The combined INS allele frequency (0.078) was similar to that observed in a control material of 416 subjects (0.075). We performed functional testing in HEK293T cells of a set of CEL-INS variants, in which the insertion site varied from the first to the 12th VNTR repeat. Lipase activity showed little difference among the variants. However, CEL-INS variants with insertions occurring in the most proximal repeats led to protein aggregation and endoplasmic reticulum stress, which upregulated the unfolded protein response. Moreover, by using a CEL-INS-specific antibody, we observed patchy signals in pancreatic tissue from humans without any CEL-INS variant in the germline. Similar pancreatic staining was seen in knock-in mice expressing the most common human CEL VNTR with 16 repeats. CEL-INS proteins may therefore be constantly produced from somatic events in the normal pancreatic parenchyma.

Two bioanalytical methods, quantitative polymerase chain reaction and flow cytometry, were used for the assessment of cellular kinetics of liso-cel, which showed high concordance for in vivo cellular expansion. Multivariable logistic regression analyses demonstrated that higher in vivo cellular expansion of liso-cel was associated with a higher overall response and complete response rate, and a higher incidence of cytokine release syndrome and neurological events in patients with relapsed or refractory LBCL.

Studies on the DEL1 variant have suggested that MODY8 is initiated by CEL protein misfolding and aggregation. However, it is unclear how the position of single-base deletions within the CEL VNTR affects pathogenic properties of the protein. Here, we investigated four naturally occurring CEL variants, arising from single-base deletions in different VNTR segments (DEL1, DEL4, DEL9, and DEL13). When the four variants were expressed in human embryonic kidney 293 cells, only DEL1 and DEL4 led to significantly reduced secretion, increased intracellular aggregation, and increased endoplasmic reticulum stress compared with normal CEL protein. The level of O-glycosylation was affected in all DEL variants. Moreover, all variants had enzymatic activity comparable with that of normal CEL. We conclude that the longest aberrant protein tails, resulting from single-base deletions in the proximal VNTR segments, have highest pathogenic potential, explaining why DEL1 and DEL4 but not DEL9 and DEL13 have been observed in patients with MODY8.

Here we report that polyQ expansion reduces in vitro binding of TBP to DNA and that mutant TBP fragments lacking an intact C-terminal DNA-binding domain are present in transgenic SCA17 mouse brains. polyQ-expanded TBP with a deletion spanning part of the DNA-binding domain does not bind DNA in vitro but forms nuclear aggregates and inhibits TATA-dependent transcription activity in cultured cells.

The aim of this study was to identify transcription factors responsible for the regulation of this VNTR. Using a yeast one-hybrid screen, we found the transcription factor Y box binding protein 1 (YB-1) interacts with the 5-HTT VNTR. Consistent with this, we demonstrate in a reporter gene assay that the polymorphic VNTR domains differentially respond to exogenous YB-1 and that YB-1 will bind to the VNTR in vitro in a sequence-specific manner. Interestingly, the transcription factor CCTC-binding factor (CTCF), previously shown to interact with YB-1, interferes with the ability of the VNTR to support YB-1-directed reporter gene expression. In addition, CTCF blocks the binding of YB-1 to its DNA recognition sequences in vitro, thus providing a possible mechanism of regulation of YB-1 activation of the VNTR by CTCF. Therefore, we have identified YB-1 and CTCF as transcription factors responsible, at least in part, for modulation of VNTR function as a transcriptional regulatory domain.

This gain-of-function mutation is associated with huntingtin aggregation and cell death. Autophagy is an important clearance route for mutant huntingtin exon 1. While mammalian target of rapamycin (mTOR) is a key regulator of autophagy, the upstream modifiers of this process are poorly understood. Our previous expression profiling studies in HD cell models observed changes in four genes associated with glucose metabolism, including the GLUT1 glucose transporter. A role for intracellular glucose as a modulator for polyglutamine toxicity was suggested as cell death was reduced by GLUT1 overexpression. Here we show that the protective effect of GLUT1 is associated with decreased huntingtin exon 1 aggregation in cell models. Consistent with this result, we also observed reduced aggregation and enhanced clearance of mutant huntingtin when cells were cultured in raised glucose concentrations (8 g/l). These effects were mimicked by 8 g/l 2-deoxyglucose (2DOG) (transported, phosphorylated but not metabolized further), but not with 8 g/l 3-O-methyl glucose (transported but not metabolized further). Thus, this phenomenon is probably mediated by glucose-6-phosphate. Increased clearance of mutant huntingtin by raised glucose (8 g/l) and 2DOG correlated with increased autophagy and reduced phosphorylation of mTOR, S6K1 and Akt. Thus, raised intracellular glucose/glucose 6-phosphate levels reduce mutant huntingtin toxicity by increasing autophagy via mTOR and possibly Akt.

Specifically, mtDNA damage was a prominent finding in development of disease in the ultraviolet-A (UVA) induced FECD mouse model. We hypothesize that an aberrant DNA repair may contribute to the increased DNA damage seen in FECD. We analyzed differential expression profiles of 84 DNA repair genes by real-time PCR arrays using Human DNA Repair RT-Profiler plates using cDNA extracted from Descemet's membrane-corneal endothelium (DM-CE) obtained from FECD patients with expanded (>40) or non-expanded (<40) intronic CTG repeats in TCF4 gene and from age-matched normal donors. Change in mRNA expression of <0.5- or >2.0-fold in FECD relative to normal was set as cutoff for down- or upregulation. Downregulated mitochondrial genes were further validated using the UVA-based mouse model of FECD. FECD specimens exhibited downregulation of 9 genes and upregulation of 8 genes belonging to the four major DNA repair pathways, namely, base excision repair (BER), nucleotide excision repair (NER), mismatch repair (MMR), and double strand break (DSB) repair, compared to normal donors.

The objective of our study was to determine whether humanized MUC1 MAbs and Abs induced by vaccination of breast cancer patients with MUC1 peptides can effect an antibody-dependent cell-mediated cytotoxicity (ADCC). An in vitro assay has been set up in which the breast tumor cell line ZR-75-1 is used as target and PBMC of healthy donors as effector cells. Different target and effector cells, as well as various MUC1 MAbs were tested to optimize the efficacy of the in vitro assay. The humanized MAb HuHMFG-1, which recognizes the PDTR sequence in the MUC1 tandem repeat, induced a strong cell-mediated cytotoxicity. Nine MUC1-expressing tumor cell lines, including 3 bone marrow-derived cell lines, as well as 2 MUC1-transfected cell lines were susceptible to different extent to MUC1 Ab-dependent killing. Large variations in the killing capacity of PBMC from healthy donors were found. The NK cells were the essential effector cells for the MUC1 Ab-dependent killing. Plasma samples with induced high levels of MUC1 Ab were obtained from breast cancer patients repeatedly immunized with a KLH-conjugated 33-mer or 106-mer MUC1 tandem repeat. Pre- and post-vaccinated plasma samples of these patients were compared in the ADCC assay and it could be clearly demonstrated that the induced MUC1 Abs can effect tumor cell killing.

Comparative genome analysis suggested a stabilizing influence of CAA interspersions in repeat tract in THAP11 but not in SMARCA2.

The factors contributing to the disease-specific over-expression of the MUC1 gene are under intensive investigation and are yet to be determined. A large transcribed region of the human MUC1 gene is a CpG island that consists of 60-bp tandemly repeating units, each of which contains one SmaI restriction site. The methylation status of regulatory regions, upstream to the transcriptional start site, is essential for the regulation of gene expression. We therefore evaluated whether the methylation status of the various regions of the MUC1 gene may affect its expression. Using SmaI, and its isoschizomer XmaI endonucleases, we demonstrated that in peripheral-blood leukocytes (PBL-DNA) that do not express the MUC1 gene, the repeat array is completely methylated, whereas the same sequences are entirely non-methylated in breast-tumor-tissue DNA (BT-DNA). In contrast, sequences upstream and downstream to the repeat array showed no difference in the methylation pattern in PBL-DNA and BT-DNA. Hypomethylation within the repeat array was also observed in other epithelial tissues that express the MUC1 gene at much lower levels to those seen in breast-cancer tissue.

To provide an overview of the genetic and clinical features of 39 families with complex IPNs from central south China and to optimize the molecular diagnosis approach to this group of heterogeneous diseases, a total of 39 index patients from unrelated families were enrolled, and detailed clinical data were collected. TTR Sanger sequencing, hereditary spastic paraplegia (HSP) gene panel, and dynamic mutation detection in spinocerebellar ataxia (SCAs) were performed according to the respective additional clinical features. Whole-exome sequencing (WES) was used in patients with negative or unclear results. Dynamic mutation detection in NOTCH2NLC and RCF1 was applied as a supplement to WES. As a result, an overall molecular diagnosis rate of 89.7% was achieved. All 21 patients with predominant autonomic dysfunction and multiple organ system involvement carried pathogenic variants in TTR, among which nine had c.349G\u2009>\u2009T (p.A97S) hotspot variants. Five out of 7 patients (71.4%) with muscle involvement harbored biallelic pathogenic variants in GNE. Five out of 6 patients (83.3%) with spasticity reached definite genetic causes in SACS, KIF5A, BSCL2, and KIAA0196, respectively. NOTCH2NLC GGC repeat expansions were identified in all three cases accompanied by chronic coughing and in one patient accompanied by cognitive impairment. The pathogenic variants, p.F284S and p.G111R in GNE, and p.K4326E in SACS, were first reported. In conclusion, transthyretin amyloidosis with polyneuropathy (ATTR-PN), GNE myopathy, and neuronal intranuclear inclusion disease (NIID) were the most common genotypes in this cohort of complex IPNs.

Result of the previous studies have been equivocal and could be attributable to the multicentric study design with different experts examining heterogeneous TS population of various ethnic background. Methods A cross-sectional single center study from Northern India. Fifty nine diagnosed subjects of TS and their parents participated in the study. Parental origin of intact X-chromosome was determined using 12 highly polymorphic short tandem repeats (STR) on X-chromosome. For the evaluation of parent-of-origin effects, typical phenotypic traits including congenital malformations, anthropometry, body composition by dual energy X-ray absorptiometry (DXA) and biochemical profile were compared. Clinical stigmata of TS in all subjects were examined by a single expert. Results The intact X-chromosome was of maternal origin (Xm) in 49.1% subjects while 50.9% had paternal origin (Xp). Skeletal anomalies were more common in Xm group, out of which prevalence of short neck and short fourth metatarsal reached statistical significance (p=0.04 and 0.01 respectively). A strong correlation was observed between subject's baseline height standard deviation score (Ht SDS) and paternal height (r=0.593, p<0.001), maternal height (r=0.564, p<0.001) and mid-parental height (MPH) (r=0.372, p=0.047) in Xp group. This effect was not seen in Xm subjects whose baseline Ht SDS showed no significant correlation with maternal height, paternal height or MPH. No differences were detected between the groups with regard to biochemical profile or body composition. Conclusions We speculate that the differences in skeletal anomalies and height correlations between Xm and Xp groups could be due to the modifying effect of epigenetic signature on short stature homeobox (SHOX) gene of Xm.

In OPMD muscles, as in models, PABPN1 accumulates in intranuclear inclusions (INIs) whereas in other diseases caused by similar polyalanine expansions, the mutated proteins have been shown to abnormally accumulate in the cytoplasm. This study presents the impact on the subcellular localization of PABPN1 produced by large expansions or deletion of its polyalanine tract. Large tracts of more than 24 alanines result in the nuclear accumulation of PABPN1 in SFRS2-positive functional speckles and a significant decline in cell survival. These large expansions do not cause INIs formation nor do they lead to cytoplasmic accumulation. Deletion of the polyalanine tract induces the formation of aggregates that are located on either side and cross the nuclear membrane, highlighting the possible role of the N-terminal polyalanine tract in PABPN1 nucleo-cytoplasmic transport.

The high frequency of rs17884724:A>C in 7-alanine expansion (27-alanine) mutations also supported the unequal crossover mechanism for polyalanine expansion. We also confirmed the paternal origin of de novo polyalanine expansion mutation and unequal sister chromatid exchange association in three more patients.

In the homozygous group, 6/9 were 45,X and 3/9 were 46,XX. In the heterozygous group, 17/21 were 46,XX, and 4/21 were TS patients with mosaicism (45,X/46,XX; 45,X/46XiXq; 46XdelXp). The pattern obtained by GeneScan in two patients with mosaicism in the karyotype was an imbalance between the peak heights of the two alleles, suggesting that this imbalance could be present when there is a mosaicism. The frequency of TS abnormalities (18.7%) did not differ between TS and 46,XX girls. Thus, it is important to accurately assess the incidence of TS in growth-retarded girls, even in the absence of other dysmorphisms. In this study, we diagnosed 6 cases of TS 45,X (9.4%) by molecular analysis, with a 100% sensitivity and 85% specificity. This molecular analysis was able to detect all cases of TS 45,X and the majority of mosaicisms, without the need for more X chromosome markers. In conclusion, determining the number of CAG repeats of the androgen receptor gene analyzed by GeneScan was a fast method with high sensitivity for the detection of TS 45,X, suggesting that it could be interesting as a method for screening a population of growth-retarded girls.", + "publisher": "Asian Pacific journal of cancer prevention : APJCP", + "issn": "2476-762X", + "date": "2015-01-01", + "abstract": "Thymidylate synthase (TS) catalyzes the methylation of deoxyuridylate to deoxythymidylate and is involved in DNA methylation, synthesis and repair.

The TS gene promoter enhancer region contains two different polymorphisms which can influence TS mRNA transcriptional and translational efficiency: a polymorphic tandem repeat sequence (2 or 3 repeats; 2R and 3R) and a single nucleotide polymorphism (SNP), G > C, within the second repeat of the 3R alleles. We studied the relationship between tumoural TS mRNA expression levels and TS gene polymorphisms in the colonic mucosa of 48 colorectal cancer patients. The 3R/3R genotype was characterised by higher TS mRNA levels in the tumour than the 2R/2R-2R/3R genotypes (P = 0.071). Regarding the relationship with the SNP polymorphism, a statistically significant difference in TS gene expression between the 3RG/3RG genotype and 2R/2R-2R/3RC-2R/3RG genotype subset was observed (P = 0.017). No statistically significant correlation was observed between experimental data and baseline clinical-pathological characteristics as well as clinical outcome in the relatively small patient series investigated. This is the first study reporting an association between the TS intra-repeat SNP and gene expression levels in colorectal cancer patients. These results suggest that in 3R/3R patients, the G > C polymorphism may be an important factor in determining TS mRNA expression levels, and warrant further investigation of the role of TS promoter polymorphisms as predictors of sensitivity to 5-FU-based chemotherapy in larger case series.", - "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:16182121" + "id": "omim:601068", + "manubot_success": false, + "link": "https://omim.org/entry/601068", + "note": "WARNING: Manubot does not support url:https://omim.org/entry/601068.

However, it is not yet elucidated whether the TS genotype is identical in tumor and normal tissue. In this study, we investigated the TS genotype in 151 matched tumor and normal DNA samples isolated from colorectal cancer and adjacent normal tissues by PCR analysis. The results showed that TS genotypes are identical in normal and tumor tissues of homozygous individuals, suggesting that the repeat sequence is stable through carcinogenesis. However, in heterozygous samples, an imbalance between the 2R and 3R alleles in the tumor DNA was frequently observed, suggesting loss of heterozygosity (LOH) at the TS locus. Detailed LOH analysis revealed that 62% (31 of 50) of 2R/3R-heterozygous samples had LOH. Frequent LOH at the TS locus was confirmed by RT-PCR of TS mRNA and microsatellite analysis using the marker D18S59, located on 18p11.3. There was no difference in the expressions of TS mRNA and TS protein between LOH and non-LOH samples. However, when the heterozygous genotype bearing LOH was subdivided according to the number of repeats, the cancer tissue with 2R/loss genotype expressed a significantly lower level of TS protein than did that with 3R/loss genotype. The results suggest that the difference in TS genotype between tumor and normal tissue due to LOH should be considered when the genotype is analyzed with normal tissue, such as peripheral blood cells, because it is important for TS protein expression.", - "language": "en", - "note": "This CSL Item was generated by Manubot v0.6.1 from its persistent identifier (standard_id).\nstandard_id: pubmed:12460463" + "id": "omim:613267", + "manubot_success": false, + "link": "https://omim.org/entry/613267", + "note": "WARNING: Manubot does not support url:https://omim.org/entry/613267.

We queried 6,495 genome sequencing datasets and identified the repeat expansion in seven additional pedigrees. Ultrarare DNA variants near the repeat expansion indicate a common distant founder event in Sweden. Intranuclear ZFHX3-p62-ubiquitin aggregates were abundant in SCA4 basis pontis neurons. In fibroblasts and induced pluripotent stem cells, the GGC expansion led to increased ZFHX3 protein levels and abnormal autophagy, which were normalized with small interfering RNA-mediated ZFHX3 knockdown in both cell types. Improving autophagy points to a therapeutic avenue for this novel polyG disease. The coding GGC-repeat expansion in an extremely G+C-rich region was not detectable by short-read whole-exome sequencing, which demonstrates the power of LR-GS for variant discovery.", - "language":
