USP33 inhibited tumor growth of GAC. (A) Immunoblotting showed a lower USP33 level in 2 GAC cell lines, AGS and MKN45, compared to that in human normal gastric epithelial cells (HGaEpC). (B) Transfection efficiency of USP33 was tested by Western blot in both AGS and MKN45 cells. (C) MTT experiments found that USP33 ectopic expression significantly inhibited the cellular proliferation. All experiments were performed at least 3 times. * P<0.05 compared to control (CTL) group.
