Examination of bivalently marked sites. (A) Summary of bivalent sites and clustered sites in EP156T, EPT1 and EPT2 cells. (B) Epigenetic modifications of the androgen receptor (AR) gene in EP156T cells. The red box indicates a bivalent H3K4/K27me3 site. The green box indicates H3K4/K27me3/DNAMe trivalent sites. (C) Epigenetic modifications of the prostaglandin F receptor (PTGFR) gene in EPT1 cells. The green box shows a bivalent H3K4me3/DNAMe site. (D) Epigenetic modifications of the PAX9 gene in EPT2 cells. The green box shows DNAMe only modified region, the red box shows an H3K27me3 only modified region and blue boxes show H3K4me3 only modified regions.
