One report revealed that increased expression of the histone methyltransferase enhancer of Zeste Homolog 2 (EZH2) is induced by BPA with consequent increase in the overall level of histone H3 trimethylation at lysine 27 (H3K27me3), both in human breast cancer cells and in mouse mammary glands [13]. This evidence concerns the gene EZH2 and breast carcinoma.
