miR-138 inhibits the cell mobility and the regulated the expression of proteins related to apoptosis and invasion in vitro. (A) A transwell assay and (B) wound-healing assay were used to assess invasion. Magnification, ×200. (C) Caspase-3, Bax, Bcl-2 and MMP9 expression in the transfected cells was evaluated by western blot analysis, and β-actin was used as the control. Data are presented as the mean ± standard deviation. *P<0.05. miR, microRNA; MMP, matrix metalloproteinase; NC, negative control.
