摘要: Estrogen signaling plays an important role in pituitary development and function. In sensitive rat or mice strains of both sexes, estrogen treatments promote lactotropic cell proliferation induce the formation adenomas (dominantly prolactin growth-hormone-secreting ones). male patients receiving estrogen, treatment does not necessarily result hyperplasia, hyperprolactinemia adenoma development. this review, we comprehensively analyze mechanisms action upon their application animal models comparing it with available data human subjects. Sex-specific molecular targets (PRL) cells are highlighted context proliferative secretory activity. addition, putative effects estradiol on cellular/tumor microenvironment contribution postnatal progenitor/stem transdifferentiation processes to prolactinoma have been analyzed. Finally, estrogen-induced morphological hormone-secreting changes thyrotropic (TSH) adrenocorticotropic (ACTH) discussed, as well thyroid and/or glucocorticoid hormones development, based current scarce literature.
