(Submitter supplied) Alterations of chromatin modifiers are frequent in cancer but their functional consequences remain often unclear. Focusing on the Polycomb protein EZH2 that deposits H3K27me3 mark, we showed that its high expression in solid tumors is a consequence, and not a cause, of tumorigenesis. In mouse and human models, EZH2 is dispensable for prostate cancer development and restrains breast tumorigenesis. High EZH2 expression in tumors results from a tight coupling to proliferation to ensure H3K27me3 homeostasis. more...

(Submitter supplied) Polycomb Repressive Complex 2 (PRC2) plays a key role in controlling transcriptional repression. It is thought to act at the level of the chromatin, where its enzymatic subunits Ezh1 and Ezh2 catalyse the di/tri-methylation of histone H3 on its lysine 27 (H3K27me3). We sought to assess several parameters of PRC2-mediated transcriptional repression. To this end we performed a comparative analysis of mES and iMEF cells following deletion of Ezh2, a time-course analysis following deletion of Ezh2 in iMEFs as well as rescue experiments with Ezh1 and Ezh2 before or after deletion of Ezh2.
