Polyglutamine expansion (polyQ) in the protein huntingtin is pathogenic and responsible for the neuronal toxicity associated with Huntington's disease (HD). Although wild-type huntingtin possesses antiapoptotic properties, the relationship between the neuroprotective functions of huntingtin and pathogenesis of HD remains unclear. Here, we show that(More)
A defect in microtubule (MT)-based transport contributes to the neuronal toxicity observed in Huntington's disease (HD). Histone deacetylase (HDAC) inhibitors show neuroprotective effects in this devastating neurodegenerative disorder. We report here that HDAC inhibitors, including trichostatin A (TSA), increase vesicular transport of brain-derived(More)
Huntingtin is the protein mutated in Huntington's disease, a devastating neurodegenerative disorder. We demonstrate here that huntingtin is essential to control mitosis. Huntingtin is localized at spindle poles during mitosis. RNAi-mediated silencing of huntingtin in cells disrupts spindle orientation by mislocalizing the p150(Glued) subunit of dynactin,(More)
