(Submitter supplied) Evaluation of transcriptional changes in the striatum may be an effective approach to understanding the natural history of changes in expression contributing to the pathogenesis of Huntington disease (HD). We have performed genome-wide expression profiling of the YAC128 transgenic mouse model of HD at 12 and 24 months of age using two platforms in parallel; Affymetrix and Illumina. We performed gene expression profiling on the same striatal mRNA across both platforms. more...

(Submitter supplied) The polyglutamine expansion in huntingtin (Htt) protein is a cause of Huntington’s disease (HD). Htt is an essential gene as deletion of the mouse Htt gene homolog (Hdh) is embryonic lethal in mice. Therefore, in addition to elucidating the mechanisms responsible for polyQ-mediated pathology, it is also important to understand the normal function of Htt protein for both basic biology and for HD. To systematically search for a mouse Htt function, we took advantage of the Hdh +/- and Hdh-floxed mice and generated four mouse embryonic fibroblast (MEF) cells lines which contain a single copy of the Hdh gene (Hdh-HET) and four MEF lines in which the Hdh gene was deleted (Hdh-KO). more...

(Submitter supplied) Therapeutic development for Huntington's disease (HD) would benefit from a method to monitor disease progression and treatment efficacy, ideally using blood biomarkers. Previously, HD-specific signatures were identified in human blood which adequately represented signatures in human brain, showing biomarker potential. Since drug candidates are normally first screened in rodent models, we aimed to identify HD-signatures in blood and brain of YAC128 HD mice and validate these with our previously identified human signatures. more...

(Submitter supplied) Huntington’s Disease (HD) is an inherited neurodegenerative disease caused by a glutamine repeat expansion in huntingtin protein. Transcriptional deregulation and altered energy metabolism have been implicated in HD pathogenesis. We report here that mutant huntingtin causes disruption of mitochondrial function by inhibiting expression of PGC-1a, a transcriptional coactivator that regulates several metabolic processes including mitochondrial biogenesis and respiration. more...

(Submitter supplied) Gene expression profiling of purified medium spiny neurons (MSNs) in R6/2 Huntington’s disease (HD) model mouse. To purify MSNs by FACS, R6/2 was crossed with Scn4b-Venus transgenic mouse expressing Venus in MSNs. MSN gene set excluded gene expression alterations in other neuronal populations, indicating the gene set displays MSN-specific pathological changes in HD. We identified the dysregulated genes expression, which are associated with apoptosis and transcriptional regulation, and found considerable number of disease causative genes in MSN gene set.

(Submitter supplied) Huntington disease (HD) is a fatal neurodegenerative disorder without cure, caused by an aberrant expansion of CAG repeats in the exon 1 of the Huntingtin (HTT) gene. Although the negative correlation between the number of CAG repeats and the age of disease onset is well established, additional factors may contribute to the high heterogeneity in the complex manifestation of the symptoms among patients. more...
