Effects of miR-221-3p on NSCLC cells. a, b CCK-8 experiment was adopted to detect the effects of overexpression or inhibition of miR-221-3p on the viability of A549 and H1299 cells, respectively. c EdU experiment was applied to detect the effect of overexpression or inhibition of miR-221-3p on the proliferation of A549 and H1299 cells, respectively. d, e Transwell expeimrnt was employed to detect the effects of overexpression or inhibition of miR-221-3p on the migration and invasion of A549 and H1299 cells, respectively. *, **, *** represent p < 0.05, p < 0.01, and p < 0.001, respectively
