If miR-24-1 was a negative tissue-specific regulator of the menin oncosuppressor protein, then miR-24-1 should be over-expressed in MEN1 parathyroid adenomatous tissues versus sporadic non-MEN1 forms of parathyroid adenomas as well as in healthy parathyroid tissue. This evidence concerns the gene MEN1 and parathyroid gland adenoma.
