Three groups of proteins deﬁne the state of chromatin. “Writer” proteins are required for add- WebDec 30, 2015 · The heterochromatin is generally characterized by hypoacetylation of the histone tails, which is attributed to the function of HDACs. Thus, treatment with HDAC inhibitors can be expected to reduce the amount of the heterochromatin in cells and increase the formation of UV-induced 6-4PP and cisplatin-induced Pt-GG.

The … WebJun 1, 2007 · These changes are associated with the loss of interaction of HDACs and the heterochromatin protein HP1 with histone H3. These data strongly indicate that histone hyperacetylation is not always the result of a loss of HDAC activity, but that it could be due to a loss of HDAC targeted to specific DNA sequences. ...
