LncRNA CASC7 regulates miR-92a expression to suppress NSCLC cell growth and invasion. A549 and H358 cells were co-transfected with pcDNA-CASC7 and miR-92a mimics, and were then harvested for subsequent experiments. (A and B) Cell viability was determined by Cell Counting Kit-8 assay. (C) The protein expression of PCNA was detected by western blotting. (D and E) The activity of caspase-3 was measured by a commercial kit. (F-H) The migration of A549 and H358 cells was determined by wound healing assay. (I-K) The invasion of A549 and H358 cells was determined by Transwell assay with Matrigel coating. Data are presented as means ± standard deviation from three independent experiments, *P<0.05, **P<0.01 vs. control group; ##P<0.01 vs. pcDNA-CASC7. NSCLC, non-small cell lung cancer; PCNA, proliferating cell nuclear antigen.
