A. miR-21 expression in transfected RBE and QBC939 cells. The results were normalized to U6 expression cell. B. Scratch wound healing assay showed that miR-21 over-expression promoted cell migration compared with NC group. Inhibition of mir-21 decreased the migration capacity. C-F. Migratory and invasive capacity of RBE and QBC939 cells transfected with miR-21 mimics or treated with miR-21 inhibitor were tested by migration and invasion assay in transwell plates (original magnification 200). The cells were counted and analyzed in histogram; *P < 0.05, **P < 0.01 versus the parental cell (cell group).
