DANCR is highly expressed in CC patients and is correlated with poor prognosis. Microarray analysis was performed between normal tissues and tumor tissues by Arraystar Human LncRNA microarray V2.0 (Agilent_033010 Probe Name version). a, heatmap for 30 differentially expressed lncRNAs; b, 5 mostly changed lncRNAs between normal tissues and tumor tissues detected assessed using RT-qPCR; c, Kaplan-Meier survival analysis of CC patients with high (n = 35) or low DANCR expression (n = 34); d, DANCR expression in normal colon epithelial cell line FHC and CC cell lines measured using RT-qPCR. Data are expressed as mean ± SD; in panel B, data were analyzed using the paired t-test, data in panel D were analyzed using one-way ANOVA and Tukey’s multiple comparison test; *, p < 0.05
