Role of miR-24 in Multiple Endocrine Neoplasia Type 1: A Potential Target for Molecular Therapy.

Int J Mol Sci 2021 Jul 8;22(14). Epub 2021 Jul 8.

F.I.R.M.O., Italian Foundation for the Research on Bone Diseases, Via Reginaldo Giuliani 195/A, 50141 Florence, Italy.

Multiple endocrine neoplasia type 1 (MEN1) is a rare autosomal dominant inherited multiple cancer syndrome of neuroendocrine tissues. Tumors are caused by an inherited germinal heterozygote inactivating mutation of the tumor suppressor gene, followed by a somatic loss of heterozygosity (LOH) of the gene in target neuroendocrine cells, mainly at parathyroids, pancreas islets, and anterior pituitary. Over 1500 different germline and somatic mutations of the gene have been identified, but the syndrome is completely missing a direct genotype-phenotype correlation, thus supporting the hypothesis that exogenous and endogenous factors, other than specific mutation, are involved in MEN1 tumorigenesis and definition of individual clinical phenotype.
