REST/NRSF is a multifunctional transcription factor that represses or silences many neuron-specific genes in both neural and non-neural cells by recruitment to its cognate RE1/NRSE regulatory sites. An increase in RE1/NRSE genomic binding is found in Huntington's disease (HD), resulting in the repression of REST/NRSF regulated gene transcription, among(More)
Huntington's disease (HD) is a neurodegenerative disorder that affects muscle coordination and diminishes cognitive abilities. The genetic basis of the disease is an expansion of CAG repeats in the Huntingtin (Htt) gene. Here we aimed to generate a series of mouse neural stem (NS) cell lines that carried varying numbers of CAG repeats in the mouse Htt gene(More)
Increased levels of the repressor element 1/neuron restrictive silencer element (RE1/NRSE) silencing activity promoter, and a consequent reduction in the transcription of many RE1/NRSE-bearing neuronal genes, including brain-derived neurotrophic factor (BDNF), have been demonstrated in Huntington disease (HD) and represent one possible effector of its(More)
Transcriptional dysregulation is a hallmark of Huntington's disease (HD) and one cause of this dysregulation is enhanced activity of the REST-mSIN3a-mSIN3b-CoREST-HDAC repressor complex, which silences transcription through REST binding to the RE1/NRSE silencer. Normally, huntingtin (HTT) prevents this binding, allowing expressing of REST target genes.(More)
REST/NRSF is a transcription factor that represses transcription of several neuronal genes by binding to a DNA regulatory motif known as Repressor Element 1/Neuron-restrictive silencer element (RE1/NRSE). In Huntington's Disease, an inherited degenerative disease affecting the brain, REST/NRSF enters pathologically into the nucleus of affected cells,(More)
The potential use of neural stem cells (NSCs) in basic research, drug testing, and for the development of therapeutic strategies is dependent on their large scale in vitro amplification which, however, introduces considerable risks of genetic instability and transformation. NSCs have been derived from different sources, but the occurrence of chromosomal(More)
