A Enrichment of histone H3, AcH3, total RNPII, ser5-p RNPII, ser2-p RNPII, and NELF-E in the basal state (0 hours) and after treatment (2 and 4 hours) with 20 ng/ml TNF quantified using ChIP and shown as % input (non-IP control). Data are presented as mean ± standard error of the mean (s.e.m.) of three biological replicates. Significance calculated by Dunnett's multiple comparison test (* p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001).
