This is followed by progressive chorea, dementia and emotional dysfunction, eventually resulting in death. HD is caused by an expanded CAG repeat in the first exon of the HD gene that results in an abnormally elongated polyQ (polyglutamine) tract in its protein product, Htt (Huntingtin). Wild-type Htt is largely cytoplasmic; however, in HD, proteolytic N-terminal fragments of Htt form insoluble deposits in both the cytoplasm and nucleus, provoking the idea that mutHtt (mutant Htt) causes transcriptional dysfunction. While a number of specific transcription factors and co-factors have been proposed as mediators of mutHtt toxicity, the causal relationship between these Htt\/transcription factor interactions and HD pathology remains unknown. Previous work has highlighted REST [RE1 (repressor element 1)-silencing transcription factor] as one such transcription factor. REST is a master regulator of neuronal genes, repressing their expression. Many of its direct target genes are known or suspected to have a role in HD pathogenesis, including BDNF (brain-derived neurotrophic factor). Recent evidence has also shown that REST regulates transcription of regulatory miRNAs (microRNAs), many of which are known to regulate neuronal gene expression and are dysregulated in HD. Thus repression of miRNAs constitutes a second, indirect mechanism by which REST can alter the neuronal transcriptome in HD. We will describe the evidence that disruption to the REST regulon brought about by a loss of interaction between REST and mutHtt may be a key contributory factor in the widespread dysregulation of gene expression in HD.<\/jats:p>","DOI":"10.1042\/bst0371270","type":"journal-article","created":{"date-parts":[[2009,11,19]],"date-time":"2009-11-19T18:02:29Z","timestamp":1258653749000},"page":"1270-1275","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":58,"title":["Transcriptional dysregulation of coding and non-coding genes in cellular models of Huntington's disease"],"prefix":"10.1042","volume":"37","author":[{"given":"Angela","family":"Bithell","sequence":"first","affiliation":[{"name":"Department of Neuroscience, Institute of Psychiatry, King's College London, CCBB, London SE5 9JU, U.K."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rory","family":"Johnson","sequence":"additional","affiliation":[{"name":"Genome Institute of Singapore, 60 Biopolis Street, No. 02-01, Genome Building, 138672, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noel\u00a0J.","family":"Buckley","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Institute of Psychiatry, King's College London, CCBB, London SE5 9JU, U.K."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2009,11,19]]},"reference":[{"key":"2021111719320154500_B1","doi-asserted-by":"crossref","first-page":"971","DOI":"10.1016\/0092-8674(93)90585-E","article-title":"A novel gene containing a trinucleotide repeat that is expanded and unstable on Huntington's disease chromosomes","volume":"72","author":"The Huntington's Disease Collaborative Research Group","year":"1993","journal-title":"Cell"},{"key":"2021111719320154500_B2","doi-asserted-by":"crossref","first-page":"919","DOI":"10.1038\/nrn1806","article-title":"Normal Huntingtin function: an alternative approach to Huntington's disease","volume":"6","author":"Cattaneo","year":"2005","journal-title":"Nat.
