Description

Submission Date: Jan 21, 2016

Summary: While histone deacetylase (HDAC) inhibitors are thought to regulate gene expression by post-translational modification of histone as well as non-histone proteins. While histone hyperacetylation has long been considered the paradigmatic mechanism of action, recent genome-wide profiles indicate more complex interactions with the epigenome. In particular, HDAC inhibitors also induce histone deacetylation at the promoters of highly active genes, resulting in gene suppression. This was linked to the loss of histone acetyltransferase (HAT) binding. To illustrate pre-clinical utility of the HDAC inhibitor SAHA as a therapeutic, we show reversal of diabetes-associated EP300 target genes in diabetic HAECs of primary origin. These results were confirmed using SAHA, C646 (EP300/CREBBP inhibitor) or EP300 siRNA. These findings suggest the inhibition of gene expression by SAHA is mediated by EP300 function and provide a rationale for clinical trials of safety and efficacy in patients with diabetes.
