Knockdown of endogenous miR-21-5p increases the migration of GC9811 cells. GC9811 cells with or without knockdown of miR-21-5p were were seeded at a density of 2×105 cells per well in 6-well plates. After 12 h, a straight line was scraped. Images were captured under phase-contrast microscopy immediately and 24 h post-incision (magnification, ×100). Values are expressed as the mean ± standard deviation. **P<0.01 vs. RNAi-Vector group. RNAi, RNA interference; miR, microRNA; RNAi-Vector, scrambled control vector.
