Properties of enhancer classes. (A) Figure showing the counts of enhancer regions per class (columns) associated with genes (rows) with (from top to bottom) early induction, late induction, gradual induction, no change, and repressed expression following LPS stimulation. Number in grey are expected counts based on random permutations. The colour code represents corresponding Z scores. (B) For Rela, STAT2, Runx1, IRF1, and Ahr, the fractions of bound enhancer regions per class are shown at different time points.
