miR-129-5p inhibits SMC proliferation by targeting the Wnt5a signaling pathway. (A) miR-129-5p inhibited the proliferation of SMCs, with and without Wnt5a overexpression. (B) Western blotting indicated that miRNA-129-5p inhibited the Wnt5a signaling pathway in SMCs. miR, microRNA; SMC, smooth muscle cell; GAPDH, glyceraldehyde-3-phosphate dehydrogenase. *P<0.05, vs. the control and **P<0.01, vs. the control.
