Timecourse gene expression profiling of DLBCL cell line Karpas422 after EZH2 inhibitor treatment

ABSTRACT: Ezh2 protein is the enzymatic component of the Polycomb Repressive Complex (PRC)-2, which represses its target genes by methylating lysine 27 of histone H3 (H3K27) and regulates cell proliferation and differentiation during embryonic development. Recently, hot-spot mutations of Ezh2 have been identified in diffused large B cell lymphomas (DLBCLs) and follicular lymphomas (FLs). To investigate if tumor growth is dependent on the enzymatic activity of Ezh2, we have developed a potent and selective small molecule inhibitor, EI1, which inhibits the enzymatic activity of Ezh2 through direct binding and competing with the methyl group donor S-Adenosyl methionine (SAM). EI1-treated cells exhibit genome-wide loss of H3K27 methylation. Furthermore, inhibition of Ezh2 by EI1 in DLBCL cells carrying
