Abstract

Recent studies have demonstrated that the Ten-eleven translocation (Tet) family proteins can enzymatically convert 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC). While 5mC has been studied extensively, little is known about the distribution and function of 5hmC. Here we present a genome-wide profile of 5hmC in mouse embryonic stem (ES) cells. A combined analysis of global 5hmC distribution and gene expression profile in wild-type and Tet1-depleted ES cells suggests that 5hmC is enriched at both gene bodies of actively transcribed genes and extended promoter regions of Polycombrepressed developmental regulators. Thus, our study reveals the first genome-wide 5hmC distribution in pluripotent stem cells, and supports its dual function in regulating gene expression.
