Effect of miR-30a-5p expression on the proliferation and invasion of gastric cancer cells. (A) Reverse transcription-quantitative polymerase chain reaction was performed to measure the relative expression of miR-30a-5p in AGS cells transfected with miR-NC and miR-30a-5p mimic. Data are presented as mean ± standard deviation of at least three independent experiments (B) MTT and (C) Transwell assays were used to evaluate cell proliferation and invasion using crystal violet staining, respectively (magnification, ×40). Data are presented as mean ± standard deviation of at least three independent experiments, respectively. **P<0.01 vs. control. miR, microRNA; miR-NC, negative control miR; control, non-transfected AGS cells.
