MEN1 and tumor of parathyroid gland: Three more miRNAs (miR-664a-3p, miR-1301-3p, and miR-4258) may have a possible role in the biology of MEN1 parathyroid neoplasia by targeting oncosuppressor genes known or suspected to be involved in the development of familial forms of parathyroid tumors, such as CDC73, CDKN1B, CDKN2C, RET, AP2S1, CCND1, CCDN2, and CTNNB1 [17].
