Effect of miR-21 on the migration and invasion of NSCLC A549 cells. The cells were transfected with miR mimics-NC, miR-21 mimics, miR inhibitor-NC, or miR-21 inhibitor. (A) Expression of miR-21 in cells transfected with miR mimics-NC, miR-21 mimics, miR inhibitor-NC, or miR-21 inhibitor. *P<0.05 compared with NC group. (B) Images of migrated and invasion cells in indicated groups. Magnification, ×200. (C) The numbers of migrated and invasion cells in each group. Transwell assay was used to determine the migration and invasion of A549 cells. *P<0.05 compared with miR-NC group. NSCLC, non-small cell lung cancer; NC, negative control.
