title: Genome-wide approaches to studying chromatin modifications.
abstract: Over two metres of DNA is packaged into each nucleus in the human body in a manner that still allows for gene regulation. This remarkable feat is accomplished by the wrapping of DNA around histone proteins in repeating units of nucleosomes to form a structure known as chromatin. This chromatin structure is subject to various modifications that have profound influences on gene expression. Recently developed techniques to study chromatin modifications at a genome-wide scale are now allowing researchers to probe the complex components that make up epigenomes. Here we review genome-wide approaches to studying epigenomic structure and the exciting findings that have been obtained using these technologies.
