Relative miR-877 expression in NSCLC tissues and cell lines. (A) RT-qPCR analysis was utilized for the detection of miR-877 expression in 53 pairs of NSCLC tissues and adjacent non-tumor tissues. (B) Relative miR-877 expression was analysed by RT-qPCR in four NSCLC cell lines (H522, H460, A549 and SK-MES-1) and a non-tumorigenic bronchial epithelium cell line (BEAS-2B). *P<0.05 vs. non-tumor tissues/BEAS-2B. miR-877, microRNA-877; NSCLC, non-small cell lung cancer; RT-qPCR, reverse transcription-quantitative PCR.
