LINC02418 expression in CRC tissues and cell lines. a The differential expression of LINC02418 in CRC samples (n = 478) and adjacent normal colon tissues (n = 41) was analyzed based on TCGA; **P < 0.01, compared to adjacent tissue group. b Quantification analysis of LINC02418 level was conducted in 20 pairs of CRC samples and adjacent normal colon tissues. c LINC02418 levels in SW620, HCT116, LoVo, Colo205, HT-29, SW480 and normal colon epithelial cell line NCM460 were determined by qRT-PCR; **P < 0.01, compared to NCM460. d Kaplan–Meier analyses of the correlations between expression of LINC02418 and overall survival of patients with CRC in stage 1–2 and stage 3–4 (stage 1, 76 patients; stage 2, 168 patients; stage 3, 127 patients; stage 4, 66 patients). The error bars stand for standard deviation (SD). Data were representatives of three independent experiments with similar results
