Among numerous lncRNAs, we focus on ZNFX1 antisense RNA 1 (ZFAS1), a well-known lncRNA that is aberrant overexpression in various tumors, including melanoma, esophageal squamous cell carcinoma, non-small cell lung cancer, gastric cancer, colon cancer, and Hepatocellular carcinoma, in which it functions as oncogene. This evidence concerns the gene ZFAS1 and malignant colon neoplasm.
