About Changes in Gene Transcription

Compounds that have the ability to regulate the transcription of specific sets of genes are being proposed as possible candidates for treating HD. Some of these compounds may be able to regulate genes to produce proteins that could delay various HD symptoms. For example, some of the drugs could induce the transcription of genes responsible for the production of proteins with anti-inflammatory effects.

Histones and HDAC Inhibitors

Histone deacetylases (HDACs) are enzymes involved in expression of DNA.  Blocking these enzymes with HDAC inhibitors such as sodium butyrate and suberoylanilide hydroxamic acid (SAHA) has beneficial effects on fruit-fly and mouse models of HD. Why are HDACs significant in the study of HD and how could they lead to HD therapies? To answer these [...]
