MiR‐646 suppresses the proliferation and invasion of NSCLC cells in vitro. (A) A549 and SPC‐A1 cells were transfected with miR‐646 mimic or its inhibitor, and cell proliferation was evaluated by CCK‐8 assay. (B) Representative micrographs (left) and quantification (right) of BrdU‐incorporating cells transfected with miR‐646 mimic or its inhibitor. (C) Colony formation assay. Representative images (left) and quantification (right) of colony formation of the transfected cells. (D) Representative images (left) and quantitation (right) of the Transwell assay. *P < .05, **P < .01
