The correlation of lncRNA RGMB-AS1 and RGMB mRNA expression levels in NSCLC tissues. a, b: In poor differentiation tumor tissues, the expression levels of lncRNA RGMB-AS1 were significantly higher while RGMB mRNA were lower than in well and moderate differentiation tissues (P < 0.05). c, d: NSCLC tissues were divided into two groups of metastasis-positive and metastasis-negative. The high expression of lncRNA RGMB-AS1 and low expression of RGMB mRNA were notably associated with lymph node metastasis (P < 0.05). e, f: Significant differences were observed in lncRNA RGMB-AS1 and RGMB mRNA expression in different TNM stages (P < 0.05). P < 0.05 compared with the control group
