In 72 NSCLC tissues, we performed qRT-PCR to check lncRNA RGMB-AS1 and RGMB mRNA expression, and found that lncRNA RGMB-AS1 expression was significantly higher in NSCLC tissues than in adjacent normal tissues (P < 0.05, Fig. 1a), while RGMB mRNA showed an opposite trend (P < 0.05, Fig. 1b). The gene discussed is RGMB; the disease is non-small cell lung carcinoma.
