MiR-18a-5p is upregulated in NSCLC tissues and cell lines (a) The relative expression level obtained from the qRT-PCR results of miR-18a-5p in tumour tissues (T) and corresponding non-tumour tissues (NT). U6 was used for normalization. (b–d) Expression of miR-18a-5p related to tumour size, sex and pathological stage. (e) The relative expression level of miR-18a-5p in lung cancer cell lines and BEAS-2B cells (control) was measured by qRT-PCR (n=3 independent experiments). Error bars represent the mean±S.E.M. *P<0.05, **P<0.01, ***P<0.001
