LincIN expression is increased in ESCC and is associated with a poor prognosis of patients with ESCC. (A) The expression of LincIN in 56 pairs of ESCC tissues and adjacent noncancerous tissues was detected by RT-qPCR. P<0.0001, determined by Wilcoxon signed-rank test. (B) Kaplan-Meier survival analysis of the association between LincIN expression level and the overall survival of 56 patients with ESCC. P=0.0160, determined by the log-rank test. (C) The expression of LincIN in immortalized normal esophageal epithelial cell line, Het-1A, and the ESCC cell lines, TE-1, KYSE150 and Eca-109, was detected by RT-qPCR. Results are shown as the means ± SD from 3 separate experiments. ***P<0.001, vs. control Het-1A cells, determined by one-way ANOVA followed by Dunnett's multiple comparison test vs. Het-1A group. ESCC, esophageal squamous cell carcinoma.
