Genome-wide distribution of H3K4me1, H3K4me3, and H3K27ac modifications. a Pie charts showing the distributions of H3K4me1, H3K4me3, and H3K27ac across the genome without 20E treatment. “Promoter-TSS” indicates the region − 1 kb to + 200 bp of the TSS. b Average ChIP-seq signal profiles for genes with different expression levels were generated for the histone modifications around the TSS without 20E treatment. Genes were divided into four categories according to their mRNA levels: no expression, low-level expression, medium-level expression, and high-level expression
