title: Small molecule inhibitors of histone acetyltransferases as epigenetic tools and drug candidates.
abstract: Alteration of the acetylation state of histone proteins contributes to transcriptional regulation and epigenetic inheritance. Dysregulation of these processes may lead to human diseases, especially cancer. One of the major chromatin modifications is histone acetylation and this review gives an overview of the role of histone acetyltransferases, their structural aspects, as well as of chemical modulators targeting their enzymatical activities. Inhibitors and activators of histone acetyltransferases are presented and their capability to influence histone and non-histone protein acetylation levels is discussed. Development of small molecules as epigenetic tools that alter histone acetyltransferase activity will be helpful to better understand the consequences of histone and generally protein acetylation and potentially offer novel therapeutic approaches for the treatment of cancer and other diseases.
