The reserpine effects on the gonadotrophic cells of the male common carp Cyprinus carpio (Osteichtyes: Cyprinidae)
(Universidad de Costa Rica, 2004)
Pituitary of non-pregnant and pregnant viscachas (Lagostomus maximus maximus): a comparative study by immunohistochemical and morphometric analysis
(Elsevier Gmbh, 2010-12)
The neuroendocrine hypothalamic-pituitary axis undergoes morphological and biochemical changes throughout gestation. In viscacha, pregnancy lasts approximately 154 days, and three stages can be described: early, mid- and ...
Neuropeptide glutamic-isoleucine (NEI) specifically stimulates the secretory activity of gonadotrophs in primary cultures of female rat pituitary cells
(Elsevier Science Inc, 2009-11)
The neuropeptide EI (NEI) is derived from proMCH. It activates GnRH neurons, and has been shown to stimulate the LH release following intracerebroventricular administration in several experimental models. The aim of the ...
Adenomas hipofisários produtores de glicoproteínas: patogênese, diagnóstico e tratamento
(Sociedade Brasileira de Endocrinologia e Metabologia, 2005-10-01)
The glycoprotein-secreting pituitary adenomas comprise two distinctive clinical and pathological entities, the gonadotroph and the thyrotroph cell pituitary adenomas. Although they can be grouped together for producing ...
Effects of castration on androgen receptors and gonadotropins in the pituitary of adult male viscachas
(Csiro Publishing, 2014-08)
The aims of the present study were to determine whether castration results in quantitative immunohistochemical changes in androgen receptors (AR), LH-immunoreactive (IR) cells and FSH-IR cells, and to analyse the colocalisation ...
Modulation of the kinetics of inositol 1,4,5-trisphosphate-induced [Ca2+](i) oscillations by calcium entry in pituitary gonadotrophs
(Biophysical Society, 1997)
Inositol 1,4,5-trisphosphate (InsP3) binds to its receptor channels and causes liberation of Ca2+ from intracellular stores, frequently in an oscillatory manner. In addition to InsP3, the activation and inactivation ...
