WebMar 19, 2024 · The histone lysine N-methyltransferase EZH2 is the enzymatic component of the polycomb repressive complex 2 (PRC2) that controls stem cell maintenance and differentiation. Mutations in EZH2 exert context-specific and sometimes opposing effects on tumorigenesis. Oncogenic gain-of-function mutations found in patients with lymphoid … WebIn cancer, gain-of-function mutations in the gene encoding the enhancer of zeste homolog 2 protein (EZH2) lead to a genome-wide increase in histone-3 Lys27 trimethylation (H3K27me3) associated with transcriptional repression. However, the effects of these epigenetic changes on the structure and function of chromatin domains have not been …

WebAug 10, 2024 · Given that EZH2 is the main catalytic unit of PRC2, and that enhanced trimethylation at H3K27 has been shown in DLBCL cell lines harboring EZH2 gain-of-function mutations 42,43, our data suggest ... The first EZH2 inhibitor was 3-deazaneplanocin A (DZNep). DZNep, a known S-adenosyl-L-homocysteine (SAH) hydrolase inhibitor, indirectly inhibits EZH2 through the increase of SAH, which directly represses S-adenosyl-L-methionine-dependent histone methyltransferase activity. Thus, DZNep globally inhibits … See more In addition to targeting the enzyme catalytic domain of EZH2, disrupting the protein-protein interactions among the PRC2 subunits is a novel strategy to inhibit PRC2 … See more Combining EZH2 inhibitors with other therapy methods such as immune therapy, conventional chemotherapy, and target therapy might … See more Given the fact that EZH2 plays a PRC2- and methylation-independent role in cancer and many cancers do not respond to EZH2 enzymatic inhibitors, triggering EZH2 degradation may be a novel method to inhibit EZH2.
