Knockdown of MYBL2 inhibits the proliferation, migration and invasion of ovarian cancer cells. (A) MTT assays were performed to analyze the effect of MYBL2 on cell viability in A2780, SKOV3 and HEY cells. (B) Effect of MYBL2 knocking down on the colony formation of ovarian cancer cells. (C and D) Transwell assays of A2780, SKOV3 and HEY cells after transfection with shMYBL2 or PLKO.NC (200 ×), Scale bar: 50 µm. (Data are mean ± SEM, *P < 0.05, **P < 0.01, n = 3).
