5-Hydroxymethylcytosine Profiling in Human DNA

Methods Mol Biol. 2017:1589:89-98. doi: 10.1007/7651_2015_268.

Abstract

Since its "re-discovery" in 2009, there has been significant interest in defining the genome-wide distribution of DNA marked by 5-hydroxymethylation at cytosine bases (5hmC). In recent years, technological advances have resulted in a multitude of unique strategies to map 5hmC across the human genome. Here we discuss the wide range of approaches available to map this modification and describe in detail the affinity based methods which result in the enrichment of 5hmC marked DNA for downstream analysis.

Keywords: 5-hydroxymethylcytosine; 5hmC; 5mC; DNA immunoprecipitation and enrichment; Epigenetics; HmeDIP.
