DHCR7-DT and pituitary gland adenoma: We have previously shown that a series of human pituitary adenomas including prolactinomas, pituitary adenomas associated to multiple endocrine neoplasia type I (MEN I) disease, pituitary tumors linked to Cushing’s disease, and a few NFPA contained indeed cells storing more than one AP hormone (multihormonal cells) and/or showing responses to more than one hypothalamic releasing hormone (HRH) (multiresponsive cells) (17).
