Recently, MALAT1 was found to be overexpressed in many human carcinomas, including hepatocellular carcinomas, pancreatic cancer, bladder cancer, breast cancer, colorectal cancer, gastric cancer, and osteosarcoma [3, 4], suggesting that MALAT1 dysregulation is implicated in the development of many types of cancers [5]. This evidence concerns the gene MALAT1 and breast carcinoma.
