The recent discoveries that established histone acetylation as a key regulatory mechanism for gene expression triggered a wave of interest in histone posttranslational modifications and led to the development of novel anticancer agents now in clinical trials. In Histone Deacetylases: Transcriptional Regulation and Other Cellular Functions, a panel of leading investigators summarizes and synthesizes the new discoveries in this rapidly evolving field. The authors describe what has been learned about these proteins, including the identification of the enzymes, the elucidation of the enzymatic mechanisms of action, and the identification of their substrates and their partners. They also review the structures that have been solved for a number of enzymes-both alone and in complex with small-molecule inhibitors-and the biological roles of the several histone deacetylase (HDAC) genes that have been knocked out in mice. Authoritative and state-of-the-art, Histone Deacetylases: Transcriptional Regulation and Other Cellular Functions constitutes a first landmark of what has been accomplished so far and sets a clear agenda for the full definition of HDAC roles in biology and disease in the years to come.

Methylation of DNA at cytosine residues as well as post-translational modifications of histones, including phosphorylation, acetylation, methylation and ubiquitylation, contribute to the epigenetic information carried by chromatin. These changes play an important role in the regulation of gene expression by modulating the access of regulatory factors to the DNA. The use of a combination of biochemical, genetic and structural approaches has allowed demonstration of the role of chromatin structure in transcriptional control. The structure of nucleosomes has been elucidated and enzymes involved in DNA or histone modifications have been extensively characterized. Since deregulation of epigenetic marks has been reported in many cancers, a better understanding of the underlying molecular mechanisms bears the promise that new drug targets may soon be found. The newest developments in this quickly developing field are presented in this book.
