Correlation between net signal intensity of epigenetic modifications and gene activities of bivalently marked genes. The net intensities of H3K4me3 versus H3K27me3 or H3K4me3 versus DNAMe are shown along the X-axis. Gene expression levels are shown along the Y-axis. Genes above the horizontal lines are expressed genes. Genes below horizontal lines are considered as repressed genes. Genes to the left of vertical lines are stronger labeled by active marks. Genes to the right of vertical lines are stronger labeled by repressive marks.
