Gonadotropin-releasing hormone agonist-induced pituitary apoplexy
UNLABELLED Pituitary apoplexy represents an uncommon endocrine emergency with potentially life-threatening consequences. Drug-induced pituitary apoplexy is a rare but important consideration when evaluating patients with this presentation. We describe an unusual case of a patient with a known pituitary macroadenoma presenting with acute-onset third nerve palsy and headache secondary to tumour e...
متن کاملDifferential social regulation of two pituitary gonadotropin-releasing hormone receptors.
In many vertebrates, social interactions regulate reproductive capacity by altering the activity of the hypothalamic-pituitary-gonadal (HPG) axis. To better understand the mechanisms underlying social regulation of reproduction, we investigated the relationship between social status and one main component of the HPG axis: expression levels of gonadotropin-releasing hormone receptor (GnRH-R). So...
متن کاملSolubilization and purification of rat pituitary gonadotropin-releasing hormone receptor.
Gonadotropin-releasing hormone (GnRH) receptors were solubilized from rat pituitary membrane preparations in an active form by using the zwitterionic detergent CHAPS (3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonic acid). The solubilized receptor exhibits high affinity, saturability, and specificity. The soluble supernatant retained 100% of the original binding activity when stored at ...
متن کاملLocal Regulation of Gonadotroph Function by Pituitary Gonadotropin-Releasing Hormone.
Cultured rat pituitary cells and immortalized pituitary gonadotrophs (alphaT3-1 cells) express specific messenger RNA transcripts for GnRH and exhibit positive immunostaining for the GnRH peptide. Each cell type released GnRH during both static culture and perifusion, albeit in lesser amounts than cultured hypothalamic cells and GT1-7 neurons. In perifused pituitary cells, exposure to a GnRH ag...
متن کاملOvarian response to pregnant mare serum gonadotropin and porcine pituitary extract in gilts actively immunized against gonadotropin releasing hormone.
Two experiments were conducted to determine the effect of exogenous gonadotropins on follicular development in gilts actively immunized against gonadotropin releasing hormone (GnRH). Four gilts, which had become acyclic after immunization against GnRH, and four control gilts were given 1,000 IU pregnant mare serum gonadotropin (PMSG), while four additional control gilts were given saline. Contr...
