The recruitment of RORα and RORγ to the RORE-containing regulatory regions of Cry1 and Bmal1 was associated with chromatin modifications. (A) The association of H3K9Ac with the RORE-containing regulatory region of Cry1 and Bmal1 was analyzed by ChIP analysis using chromatin samples prepared from liver of WT, RORαsg/sg, RORγ−/− and RORαsg/sgRORγ−/− DKO mice (n = 4) and an anti-H3K9Ac antibody. (B) DNA accessibility at the RORE sites was assessed by FAIRE-QPCR analysis. FAIRE-QPCR at the RORE-containing region indicated and at a downstream distal site was performed using chromatin prepared from WT, RORαsg/sg and RORγ−/− livers collected at ZT10 or ZT22. Data represent mean ±SEM; *P < 0.05, ***P < 0.001 by ANOVA.
