miR-502-5p overexpression suppresses gastric cancer cells migration and invasion. a The wound healing analysis showed that miR-502-5p overexpression inhibited the migration ability of gastric cancer cells SGC7901 and MGC803. **P < 0.01, ***P < 0.001. The representative images were shown on top. Magnification ×200. b Transwell assays were performed to determine the migration abilities of SGC7901 and MGC803 cells transfected with miR-502-5p or miR-NC. The number of cells migrating from the transwell membrane was quantified after incubation for 24 h. Magnification ×200. Data are representative of three similar experiments. *P < 0.05, **P < 0.01. c The invasive ability was investigated by transwell-matrigel assay. The number of cells invading through the transwell membrane coated with matrigel was quantified after incubation for 24 h. Magnification ×200. Data are representative of three similar experiments. *P < 0.05, **P < 0.01
