LINC01234 is overexpressed in NSCLC and its clinical significance. a Data mining of altered lncRNA expression in TCGA NSCLC sequencing data (LUAD and LUSC). b Data mining of correlation between LINC01234 expression and lung adenocarcinoma stage in TCGA dataset. c qRT-PCR analysis of LINC01234 expression in 45 pairs of NSCLC tissues and adjacent non-tumor lung tissues. d qRT-PCR analysis of LINC01234 expression in 16HBE cells and five NSCLC cell lines. e Forty-five NSCLC tumor tissues were divided into two groups (high and low LINC01234 expression) based on the median value. f, g Relationship between LINC01234 expression and clinicopathological features of patients with NSCLC. h Kaplan–Meier survival plots of OS based on LINC01234 expression in lung cancer patients (n = 1928). *P < 0.05, **P < 0.01
