China Y.GeorgeZheng Department of Pharmaceutical and Biochemical Sciences, The University of Georgia, Athens, Georgia,USA Foreword Epigenetics refers to heritable differences in phenotype that cannot be attributed to differences in DNA sequence. Epigenetics is emerging as a cornerstone of modern biology with important and promising practical implications for current and future therapeutics. Over the past 15 years we have come to recognize that patterns of chemical modifications on chromatin (cid:1) on both proteins and DNA (cid:1) establish heritable and dynamic gene expression programsresponsible for cell type identity through development, adaptation to environmental conditions, and evolution and maintenance of disease states. Our ability to translate this growing body of knowledge into useful strategies to understand, diagnose and treat human disease depends critically on the development and applica- tion of technologies to characterize and manipulate the “epigenetic state” of normal and diseased cells and to correlate those states with phenotype. This book summarizes many of these key tech- nologies with emphasis on epigenetic regulation mediated by methylation and acetylation (cid:1) the two most abundant anddiverse epigenetic “marks.” Much progress has been made in recent years in identifying and characterizing the protein fac- tors that “write,” “read” and “erase” methyl and acetyl marks using methodologies ranging from cell and molecular biology, genomics and bioinformatics, structural biology, protein biochemistry and enzymology. These studies have described the major protein families and complexes that inter- act with and modify chromatin and have revealed many of them to be “druggable.” Indeed, the dis- covery of novel inhibitors of histone deacetylases and DNA hypomethylation agents with clinical benefits in oncology has spurred the continued development of new drugs and chemical tools for epigenetics research and therapy. However, there remains a significant gap in our understanding of the patterns of methylation and acetylation that define both normal and diseased epigenetic states. Recent large-scale projects (such as the Encode Project) to catalogue the localization of epigenetic marks along the genome in different common cell lines have provided a good starting point, but the community now needs to better understand how these patterns differ in human disease and how they can be selectively manipulated for safe therapies. The use and further development of genome- and proteome-wide technologies that can map the locations of epigenetic marks along the genome are particularly powerful in this regard. Further optimization and more widespread application of these “omics” technologies todisease tissue will be essential tothe fullrealization of new epigenetic therapies. The following survey of epigenetic technologies will serve as an important benchmark for our current capabilities and will inspire further technological advances to reduce the knowledge gap and facilitate more rapid and successful translation of epigenetics research into new diagnoses and therapies.

The term epigenetics (the prefix “epi” comes from Greek, meaning over, upon, above, in addition to) was created by Waddington in the context of connecting developmental biology and genetics [1]. To date, epige- netics is most frequently referred to as the study of meiotically and mitotically heritable changes in gene activities without alterations in the genetic DNA sequence [1(cid:1)4]. However, in recent years, it has been debated whether the heritability requirement of the term is necessary or too restrictive given that many (perhaps most) changes in gene activity modulated by chromatin modifications can occur in terminally differentiated and nondividing cells [3,5,6]. Examples include short-lived alterations in histone acetylation and methylation caused by DNA repair, cell-cycle phase, or tran- scription factor binding. Thus, there exist arguments in which epigenetic changes could be more broadly defined to encompass structural and biochemical alterations of the chromatin at any point in time under the condition that the genetic sequence is kept invariable [5,6]. Under this scheme, epigenetics does not merely refer to heritable chromatin states, but also embraces those that are transient or occur in nondividing cells. A new term, memigenetics, has recently been suggested to Y.G.Zheng(Ed):EpigeneticTechnologicalApplications.DOI:http://dx.doi.org/10.1016/B978-0-12-801080-8.00001-6 1 ©2015ElsevierInc.Allrightsreserved.
