Upregulated miR-29a suppresses migration, invasion, proliferation and promotes apoptosis of HCC cells. (A) The level of miR-29a in 3 HCC cell lines (Hep3B, HCCLM3 and Huh-7) and a normal liver cell line (HL-7702). (B) The satisfactory transfection efficiency of miR-29a mimics with HCCLM3 cells, and the IFITM3 protein expression in response to the transfection of miR-29a. (C) Wound healing assays indicated that the migration capacity of HCCLM3 cells was decreased after miR-29a upregulation. (D) The invasion and metastatic abilities of HCCLM3 cells were decreased after miR-29a upregulation. (E) EdU proliferation assays demonstrated that the proliferation abilities were significantly decreased in the miR-29a-upregulated HCCLM3 cells than that in the NC groups. (F) The apoptosis rate of HCCLM3 cells transfected with miR-29a mimics was significantly higher than in the NC groups. *P<0.05, **P<0.01, ***P<0.001 compared with the NC groups. NC, negative control; IFITM3, interferon-induced transmembrane protein 3.
