Background:
Histone H3 Lysine 27 (H3K27) methylation is correlated with transcription repression. Recently study has found that GSK126, a histone methyltransferase EZH2 inhibitor, decreases global H3K27me3 levels and effectively inhibits the proliferation of EZH2 mutant DLBCL cell lines (1). Small molecule EPZ6438, another EZH2 inhibitor, specifically inhibits cellular H3K27 methylation leading to selective apoptotic killing of SMARCB1 mutant MRT Cells (2, 3). Meanwhile, study also finds that the expression level of Histone H3K27 trimethylation (H3K27me3) is low in human bladder cancer tissues (4). There is now evidence for both increased and decreased activity of enzymes controlling H3K27 methylation in cancer, suggesting that a precise balance of this methylation is critical for normal cell growth. Restoring a normal epigenetic condition could be a rational approach for cancer treatment and specialized prevention (5). H3K27 methylation statuses can be detected by our H3K27 methylation antibody series.
