T1 Coactivation of GR and NFKB alters the repertoire of their binding sites and target genes JF Genome Research JO Genome Research YR 2011 FD September 01 VO 21 IS 9 SP 1404 OP 1416 DO 10.1101/gr.118042.110 UL http://genome.cshlp.org/content/21/9/1404.abstract AB Glucocorticoid receptor (GR) exerts anti-inflammatory action in part by antagonizing proinflammatory transcription factors such as the nuclear factor kappa-b (NFKB). Here, we assess the crosstalk of activated GR and RELA (p65, major NFKB component) by global identification of their binding sites and target genes. We show that coactivation of GR and p65 alters the repertoire of regulated genes and results in their association with novel sites in a mutually dependent manner. These novel sites predominantly cluster with p65 target genes that are antagonized by activated GR and vice versa. Our data show that coactivation of GR and NFKB alters signaling pathways that are regulated by each factor separately and provide insight into the networks underlying the GR and NFKB crosstalk.
