Effect of miR-137 mimic and inhibitor on EZH2 protein expression. (A) Western blot analysis was used to examine the protein expression of EZH2 in HepG2 cells transfected with miR-137 mimic or miR-NC. **P<0.01 vs. miR-NC. (B) HepG2 cells were transfected with miR-137 inhibitor or NC inhibitor, and reverse transcription-quantitative polymerase chain reaction was used to examine miR-137 expression. **P<0.01 vs. NC inhibitor. (C) Western blot was used to examine the protein expression of EZH2. **P<0.01 vs. NC inhibitor. miR, microRNA; NC, negative control; EZH2, enhancer of zeste 2 polycomb repressive complex 2 subunit.
