Genome-scale techniques highlight the epigenome and redefine fundamental principles of gene regulation.

The regulation of gene expression represents one of the most fundamental of biologic processes that controls cellular proliferation, differentiation, and function. Recent technological advances in genome-wide annotation together with bioinformatic/computational analyses have contributed significantly to our understanding of transcriptional regulation at the epigenomic and regulomic levels. This perspective outlines the techniques that are being utilized and summarizes a few of the outcomes.
