Effects of miR-520b on proliferation of NSCLC cells. NSCLC A549 and Calu-3 cells were transfected with miR-520b mimics. (A) The relative expression levels of miR-520b were detected with Reverse transcription-quantitative polymerase chain reaction. (B) Cell proliferation at indicated time points was detected with the cell counting kit-8 assay. (C) Cell cycle was detected with flow cytometry. *P<0.05 vs. NC. miR, microRNA; NSCLC, non-small cell lung cancer; NC, negative control; OD, optical density.
