Gene regulation by histone modifications. The correlation between occupancy of 21 different histone modifications and gene expression within 4 different regions around the TSS (up- and downstream, 1 and 20 kb), sorted by correlation in 1-kb upstream regions. Sixteen of 21 histone modifications show significant correlation in 1-kb upstream regions, while inspection of the actual value of Kendall's tau (Table S1 in Additional file 1) shows very little effect size for 6 of these 16 (<0.1).
