Metastasis-Associated Lung Adenocarcinoma Transcript 1 (MALAT1), a 6.5-knt lncRNA, has been found to be involved in multiple steps in the development of tumors and exhibits diagnostic and prognostic significance in diverse cancers, such as prostate cancer, glioma, hepatocellular carcinoma, breast cancer, lung cancer, and multiple myeloma [13, 14]. The gene discussed is MALAT1; the disease is lung cancer.
