A–H. 832/13 cells were transduced with adenoviruses overexpressing βGAL or p50 (NF-κB1). 24 h post-transduction cells were untreated (NT) or stimulated with 1 ng/mL IL-1β for 15 mins. ChIP assays were performed to determine relative occupancy of p65 (A, C, E, G) and p50 (B, D, F, H) on the CCL20 proximal (A, B) and distal promoters (C, D), and on the CCL2 (E, F) and COX2 (G, H) promoters. **, P < 0.01 vs. βGAL (IL-1β), *, P < 0.05 vs. βGAL (IL-1β), #P < 0.1 vs. βGAL (IL-1β). ChIP data are shown as means ± SEM from 3 individual experiments.
