Pituitary Apoplexy After a Single Dose of Long-Acting Octreotide
(LIPPINCOTT WILLIAMS & WILKINS, 2010)
Pituitary apoplexy (PA) is a rare and potentially life-threatening syndrome resulting from an acute infarction or hemorrhage of the pituitary gland. Although the pathogenesis is not fully understood, some predisposing ...
ACTH cells of pituitary pars distalis of viscacha (Lagostomus maximus maximus): immunohistochemical study in relation to season, sex, and growth
(Elsevier, 2006-05)
Corticotrope or ACTH cells were immunohistochemically identiWed in the pituitary pars distalis (PD) of viscacha by using the polyclonal antiserum against ACTH (1–24). The localization, distribution, shape, percentage ...
Desensitization of Angiotensin II effect on [Ca2+]i, inositol triphosphate and prolactin in pituitary cells
(American Physiological Society, 2001-12)
Activation of pituitary angiotensin (ANG II) type 1 receptors (AT1) mobilizes intracellular Ca2+, resulting in increased prolactin secretion. We first assessed desensitization of AT1 receptors by testing ANG II-induced ...
Angiotensin II phosphorylation of extracellular signal regulated kinases in rat anterior pituitary cells
(American Physiological Society, 2003-09-01)
We studied the effects of ANG II on extracellular signal-regulated kinase (ERK)1/2 phosphorylation in rat pituitary cells. ANG II increased ERK phosphorylation in a time- and concentration-dependent way. Maximum effect was ...
Role of GPER in the anterior pituitary gland focusing on lactotroph function
(BioScientifica, 2018-10)
Ovarian steroids control a variety of physiological functions. They exert actions throughclassical nuclear steroid receptors, but rapid non-genomic actions through specificmembrane steroid receptors have been also described. ...
Pituitary Carcinoma in a Bitch: Clinical, Tomographic, Histopathological and Immunohistochemistry Findings
(Universidade Federal do Rio Grande do Sul, 2022)
Estrogen receptors and signaling pathways in lactotropes and somatotropes
(Karger, 2010-12)
Estrogens are crucial determinants in the regulation of anterior pituitary function and maintenance of tissue homeostasis. Estrogen actions in this gland are exerted through both classical and non-classical mechanisms of ...
Estradiol up-regulates c-FLIPlong expression in anterior pituitary cells
(Georg Thieme Verlag Kg, 2016-04)
Anterior pituitary cell turnover depends on a tight balance between proliferation and apoptosis. We have previously shown that estrogens sensitize anterior pituitary cells to pro-apoptotic stimuli. c-FLIP (cellular-FLICE ...
Evidence of cellular senescence during the development of estrogen-induced pituitary tumors
(BioScientifica, 2015-03)
Although pituitary adenomas represent 25% of intracranial tumors, they are usually benign, with the mechanisms by which these tumors usually avoid an invasive profile and metastatic growth development still remaining ...

(Georg Thieme Verlag Kg, 2016-04)
Anterior pituitary cell turnover depends on a tight balance between proliferation and apoptosis. We have previously shown that estrogens sensitize anterior pituitary cells to pro-apoptotic stimuli. c-FLIP (cellular-FLICE ...
