Potential roles of EZH2, Bmi-1 and miR-203 in cell proliferation and invasion in hepatocellular carcinoma cell line Hep3B

Figure 2 Western blot analysis of Bmi-1 and EZH2 protein levels. A: Expression levels of Bmi-1 and EZH2 in HCC tissues and in normal tissues; B: Expression levels of Bmi-1 and EZH2 in Hep3B cells transfected with EZH2-shRNA or control vector. Lane 1 stands for the protein levels in Hep3B cells, and lane 2 stands for the protein levels in Hep3B cells transfected with EZH2-shRNA; C: Expression levels of Bmi-1 and EZH2 in Hep3B cells transfected with miR-203-shRNA or control vector. Lane 1 stands for the protein levels in Hep3B cells, and lane 2 stands for the protein levels in Hep3B cells with miR-203 overexpression.
