Detection of VSMCs proliferation and migration after transfection with miR-374 mimics and inhibitors. (A) After transfection with miR-374 mimics, the expression level of miR-374 significantly increased, whereas, after transfection with miR-374 inhibitor, miR-374 significantly decreased. (B) Overexpression of miR-374 significantly increased the proliferation of cells, while decreased miR-374 significantly inhibited the proliferation of cells. (C) Increasing the expression level of miR-374 promoted the cell migration ability, which was significantly inhibited when the expression level of miR-374 was decreased. *, P<0.05; ***, P<0.001, compared with control group.
