MALAT1 and breast cancer: For example, lncRNAs such as HOTAIR (breast cancer), NKILA (breast cancer metastasis), NBAT1 (neuroblastoma), MALAT1 (lung, breast, prostate and cervix cancer), MDC1-AS (bladder cancer), lncRNA-886 (esophageal and gastric cancers) and PCAT-1 (prostate cancer) have been implicated in tumorigenesis [17, 21, 26–33].
