EZH2 promotes gastric cancer cells proliferation by repressing p21 expression

In this study, immunohistochemical analysis was conducted to investigate the EZH2 expression in gastric cancer. We found that EZH2 levels were increased in gastric cancer tissues compared with adjacent normal tissues. Moreover, patients with high levels of EZH2 expression had a relatively poor prognosis. Furthermore, knockdown of EZH2 expression by siRNA could impair cell proliferation and invasion both in vitro and vivo. Finally, we found that EZH2 influences gastric cancer cells proliferation partly through regulating p21 expression. Our findings present that EZH2 over-expression can be identified as a poor prognostic biomarker in gastric cancer.
