Hes1 attenuates Pol II occupancy at the Cxcl1 gene body region. (a-c) Pol II occupancy on the TSS region of Cxcl1 (a), Tnf (b) and Hbb (c) in Hes1+/+Mx1-Cre (WT) and Hes1fl/flMx1-Cre (Hes1 KO) BMDMs untreated (UT) or stimulated with LPS (10 ng/ml) for 1 h. Occupancy at the Hbb locus served as a negative control (c). (d,e) Pol II ChIP followed by deep sequencing (ChIP-seq) shows Pol II distribution along the Cxcl1 (d) and Tnf (e) gene tracks in WT and Hes1 KO BMDMs untreated or stimulated with LPS (10 ng/ml) for 1 h. (f) Pausing indices computed from Pol II distribution of all genes and two gene subsets (LPS-induced genes in WT and super-induced genes as in Fig. 1a) in untreated or LPS stimulated WT and Hes1 KO BMDMs. Data shown are representative results (a-c, mean and s.d. of technical triplicate determinants) from one of five (a, left panel) or two (b-e) independent experiments, or cumulative data from five independent experiments (a, right panel).
