MiR-381 inhibits the proliferation, invasion and migration of BGC823 cells. (A) BGC823 cells were transfected with miR-381 mimic, miR-381 inhibitor mimic or scramble mimic as negative control (NC), then miR-381 expression levels were determined by RTq-PCR. The effects of miR-381 on cell proliferation, invasion and migration were determined using MTT assays (B), transwell assays with matrigel (C) and wound healing assay (D), respectively. *P<0.05 versus the control, data shown are means ± S.D.
