Identification of the expression of PCAT6 in ESCC. (A) Data from TCGA database showed the relative expression of lncRNA PCAT6 in several cancers and normal tissues. (B) The relative expression of PCAT6 in in ESCC (n = 182) and nontumorous tissues (n = 13) from TCGA database. (C) PCAT6 expression evaluated using qRT-PCR in ESCC cell lines (Eca-109, Kyse-30, TE-1, Kyse-70, Kyse-150) and normal esophageal mucosal epithelial cell line (Het-1A). (D) qRT-PCR analysis of the expression of PCAT6 expression in 44 pairs of ESCC tissues and adjacent normal tissues collected from our center. The ΔCt value was determined by subtracting the GAPDH Ct value from the PCAT6 Ct value. A smaller ΔCt value indicates higher expression. (E) Kaplan-Meier survival plots revealed that higher PCAT6 expression correlated with poor overall survival in ESCC patients. (*P < 0.05 and **P < 0.01)
