miR-148a overexpression does not affect the cell cycle. (A and B) qRT-PCR showing miR-148a expression in A549 and Calu-1 cells stably infected with an empty vector or miR-148a lentiviruses. (C) Cell cycle analysis was performed by using PI staining in A549 cells stably expressing a miRNA control, miR-148a alone, and miR-148a plus MMP15 or ROCK1 cDNA. (D) MTS assay showing rate of proliferation of A549 cells transfected with a scrambled miRNA or miR-148a. Data are presented as ± SD; **P < 0.01 by Student’s t test. ns, not significant.
