Genome-wide maps of ESRRB binding in pluripotent (2iL) and differentiated (48h, 96h) mES cells

We report the application of sequencing technology for profiling of genome-wide ESRRB binding in mouse ES cells. We generated genome-wide chromatin-state maps of mouse embryonic stem cells maintained in pluripotent state (2iL) and differentiated for 48 and 96 hours (48 and 96). We find that the large majority of ESRRB binding occurs in 2iL and at 48 hours and that several formative genes promoters are bound by ESRRB in 2iL and at 48h. Moreover ESRRB peaks on naïve genes (e.g. Tfcp2l1, Nanog) decrease as soon as cells start differentiating while peaks on formative genes are present in 2iL and the signal is maintained (or increased) at 48 hours, further endorsing the concept of Esrrb as a direct activator of the formative gene program during the Reversible phase.
