GBS- and ERRE-containing cis-regulatory elements interact with promoter regions of ESRRB- and GR-regulated genes in mouse T-ALL cells. (A) Distribution of ERREs in GR-regulated, ESRRB-dependent genes. (B) H3K27Ac Hi-ChIP tracks of 3 ESRRB/GR-dependent mouse genes show preexisting promoter interactions with active ERRE-containing enhancers known to bind the GR. Black lines indicate the anchors of interaction.
