Knockdown of miR-939 inhibits cell proliferation. miR-939 expression was detected in (A) H1299 and (B) SPCA1 cells following transfection with an miR-939 inhibitor by reverse transcription-quantitative polymerase chain reaction, with inhibitor NC-transfected cells as the control group. Cell proliferation was also detected in the (C) H1299 and (D) SPCA1 cells by a Cell Counting Kit-8 assay at 0, 24, 48 and 72 h. *P<0.05 and **P<0.01 vs. respective inhibitor NC group. miR, microRNA; NC, negative control; OD, optical density.
