Previous studies have confirmed that lncRNAs such as MALAT1 and XIST play a role in promoting proliferation and metastasis in various tumors (55, 56), while miRNAs such as miR-155-5p and miR-206 exert bidirectional regulatory functions of tumor suppression or promotion in the occurrence and development of tumors such as melanoma (57, 58). Here, MALAT1 is linked to neoplasm.
