Provides a framework to understand the basis of epigenetic regulation and to appreciate both its derivation from genetics and interdependence with genetic mechanisms. It further aims to highlight the role of the three-dimensional organization of the genetic material itself and its distribution in a functionally compartmentalized nucleus.

Epigenetics is the study of heritable changes in gene function that do not involve changes in the DNA sequence. These changes, consisting principally of DNA methylation, histone modifications, and non-coding RNAs, maintain or modulate the initial impact of regulatory factors that recognize and associate with particular genomic sequences. Epigenetic modifications are manifest in all aspects of normal cellular differentiation and function, but they can also have damaging effects that result in pathologies such as cancer. Research is continuously uncovering the role of epigenetics in a variety of human disorders, providing new avenues for therapeutic interventions and advances in regenerative medicine.
This book's primary goal is to establish a framework that can be used to understand the basis of epigenetic regulation and to appreciate both its derivation from genetics and interdependence with genetic mechanisms. A further aim is to highlight the role played by the three-dimensional organization of the genetic material itself (the complex of DNA, histones and non-histone proteins referred to as chromatin), and its distribution within a functionally compartmentalized nucleus. This architectural organization of the genome plays a major role in the subsequent retrieval, interpretation, and execution of both genetic and epigenetic information.

John Lucchesi obtained a Ph.D. in Genetics from the University of California at Berkeley. Following postdoctoral training in the Institute of Molecular Biology at the University of Oregon, he joined the faculty of the University of North Carolina in Chapel Hill, where he rose to the rank of Cary C. Boshamer Professor of Biology and Genetics. He was appointed Adjunct Professor of Genetics at Duke University and was named Senior Fellow of Churchill College, Cambridge University, UK. In 1990, he joined the faculty of the Biology Department at Emory University as Asa G. Candler Professor of Biology and Chair. Dr Lucchesi is a fellow of the AAAS, a former President of the Genetics Society of America and was named Vice-President of the XVII International Congress of Genetics. His research laboratory has focused on the regulation of transcription, the functional architecture of chromatin and the genetic regulation of development.
