In breast cancer, many lncRNAs such as MIAT (myocardial infarction-associated transcript), SNHG1 (small nucleolar RNA host gene 1), and MALAT1 (metastasis-associated lung adenocarcinoma transcript 1) have been reported to participate in the occurrence, progression, and metastasis of tumors 27-29. This evidence concerns the gene MALAT1 and breast cancer.
