PRL and pituitary gland adenoma: Analysis of miR-410 expression was enlarged to 12 prolactin (PRL)-secreting pituitary adenomas (PRL-PAs) vs. 12 growth hormone (GH)-secreting pituitary adenomas (GH-PAs), showing that this miRNA was more expressed in almost all PRL-PAs and in half of the GH-PAs, thus suggesting that its downregulation is specific of gonadotropin-secreting adenomas.
