Overexpression of Smad4 could reverse the effect of miR-324-3p on GC cells. a Smad4 protein level was detected by western blot. b Smad4 could reverse the effect of miR-324-3p on cell proliferation. c Smad4 could reverse the effect of miR-324-3p on cell vitality. d Restoration of Smad4 inhibited colony formation. e Flow cytometric assay was performed to verify that Smad4 could reverse the effect of miR-324-3p on cell apoptosis. f Transwell migration assay demonstrated that cell migration ability was restrained by overexpression of Smad4
