Epigenetic control plays an important role in gene regulation through chemical modifications of DNA and post-translational modifications of histones. An essential post-translational modification is the histone acetylation/deacetylation-process which is regulated by histone acetyltransferases (HATs) and histone deacetylases (HDACs). The mammalian zinc dependent HDAC family is subdivided into three classes: class I (HDACs 1-3, 8), class II (IIa: HDACs 4, 5, 7, 9; IIb: HDACs 6, 10) and class IV (HDAC 11). In this review, recent studies on the biological role and regulation of class IIa HDACs as well as their contribution in neurodegenerative diseases, immune disorders and cancer will be presented. Furthermore, the development, synthesis, and future perspectives of selective class IIa inhibitors will be highlighted. 相似文献

We have taken a knockout approach to interrogate the function of protein kinase D (PKD) serine/threonine kinases in lymphocytes. DT40 B cells express two PKD family members, PKD1 and PKD3, which are both rapidly activated by the B-cell antigen receptor (BCR). DT40 cells with single or dual deletions of PKD1 and/or PKD3 were viable, allowing the role of individual PKD isoforms in BCR signal transduction to be assessed. One proposed downstream target for PKD1 in lymphocytes is the class II histone deacetylases (HDACs). Regulation of chromatin accessibility via class II histone deacetylases is an important mechanism controlling gene expression patterns, but the molecules that control this key process in B cells are not known. Herein, we show that phosphorylation and nuclear export of the class II histone deacetylases HDAC5 and HDAC7 are rapidly induced following ligation of the BCR or after treatment with phorbol esters (a diacylglycerol mimetic). Loss of either PKD1 or PKD3 had no impact on HDAC phosphorylation, but loss of both PKD1 and PKD3 abrogated antigen receptor-induced class II HDAC5/7 phosphorylation and nuclear export. These studies reveal an essential and redundant role for PKD enzymes in controlling class II HDACs in B lymphocytes and suggest that PKD serine kinases are a critical link between the BCR and epigenetic control of chromatin. 相似文献
