Correlation between histone modifications and mRNA expression. mRNA expression of the genes with differentially enriched histone modification peaks. Y-axis represents the relative expression after the normalization with GAPDH, β-Actin and RSP18. Statistically significant differences are indicated as *P < 0.05 and *P < 0.01. In green are genes with differential enrichment of H3K4me3 and in red are genes with differential enrichment of both H3K27ac and H3K4me3.
