EZH2 and hepatocellular carcinoma: Furthermore, the silencing of miR-214 or overexpression of EZH2 increased EpCAM+ stem-like cells through the activation of CTNNB1. Interestingly, the up-regulation of EZH2, CTNNB1 and the down-regulation of CDH1 in HCC patients correlated with early recurrent disease and can be an independent predictor of poor survival.
