miR-103 is upregulated in non-small cell lung cancer (NSCLC) tissues and cell lines. (A) The relative mRNA expression level of miR-103 in tumor tissues and corresponding nontumor tissues. (B) The relative mRNA expression level of miR-103 in lung cancer cell lines and 16HBE cells was measured by quantitative real-time (qRT)-PCR (n = 3 independent experiments). (C) Expression of miR-103 related to tumor size. (D) Expression of miR-103 related to tumor pathological stage. (E) Kaplan–Meier analyses of cumulative survival for patients with NSCLC according to the expression of miR-103. Error bars represent the mean ± SEM. *p < 0.05, compared with control.
