Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) was found to be upregulated in renal cell carcinoma (RCC), gastric cancer (GC), gallbladder cancer (GBC), colorectal cancer (CRC), multiple myeloma, clear cell renal cell carcinoma (ccRCC), and glioma, as well as in osteosarcoma [11,12,13,14,15,16,17,18], and it has been proposed as a molecular marker therein [14,15,16,19]. This evidence concerns the gene MALAT1 and central nervous system cancer.
