In beginning the formulation for this revised volume it was felt that as this book is aimed not only at students but also at scientists, medics, and researchers, it would be critical to have a significant introductory section, allowing the reader to become acquainted with the known mechanisms by which epigenetic regulation of gene expression is achieved and how epigenetic dysregulation is a common feature in cancer [9,10]. As a concept the “idea” of an “epigenetic code” has simplifi...
