MALAT1 and neoplasm: LncRNA MALAT1 regulated the critical pathway in TNBC progression and high expression of MALAT1 can upregulate the expression levels of c-MET and SOX4 by competitive binding with targeted mRNAs such as miR-34a/c-5p and miR-449a/b, then promoting proliferation and metastasis of tumor cells [13–15].
