ZFAS1 is overexpressed in CRC tissues and correlates with pathological parameters

(A) The differentially expressed lncRNAs in colorectal cancer tissues compared with normal lung tissues in the GSE5206, GSE21510, and GSE9348 datasets. (B) The differentially expressed lncRNAs in cholangiocarcinoma, colon adenocarcinoma, esophageal carcinoma, liver hepatocellular carcinoma, pancreatic adenocarcinoma, and stomach adenocarcinoma tissues compared with normal tissues in the TCGA dataset. (C) Relative expression of ZFAS1 in tumor tissue compared with adjacent normal tissues (n = 30). ZFAS1 expression was evaluated by qRT-PCR and normalized to GAPDH expression. (D) High expression of ZFAS1 was correlated with more advanced tumor size, invasive status, and microsatellite stability. ∗p < 0.05, ∗∗p < 0.01.
