Pro-opiomelanocortin Peptides in Mouse Pituitary Cells*
Pro-opiomelanocortin (POMC) is glycosylated and proteolytically cleaved to produce a number of smaller peptide hormones including adrenocorticotropic hormone (ACTH) and endorphin in mammalian pituitary and the mouse pituitary cell Line AtT-20/DI6,. When glycosylation of POMC is inhibited in AtT-20 cells with the drug tunicamycin, a 26,000-dalton protein appears in place of the glycosylated 29,0...
متن کاملGlucocorticoid regulation of pro-opiomelanocortin gene transcription in the rat pituitary.
The effect of glucocorticoids on pro-opiomelanocortin (POMC) gene transcription in the rat pituitary has been investigated by an in vitro nuclear runoff transcription assay. Both dexamethasone and corticosterone had rapid inhibitory effects on POMC transcription in the anterior lobe but not in the intermediate lobe of the pituitary. These effects were maximal during the first hour after injecti...
متن کاملOutcome of Transphenoid Surgery for Corticotroph Pituitary Tumors
Background & Importance: The aim of this study was to demonstrate the result of transsphenoid microsurgery for Cushing disease in our center and comparing the results in details with other articles, to achieve the best decision for patients management in future. Case Presentation: Between 1991 to 2015, 50 patients suffering from Cushing disease were operated. Before operation, endocrine t...
متن کاملComplete amino acid sequence of a human pituitary glycopeptide: an important maturation product of pro-opiomelanocortin.
A glycopeptide isolated in relatively large amounts from human pituitary glands was completely purified, and its sequence was determined. The primary sequence represents the NH2-terminal 76 amino acid residues of pro-opiomelanocortin (POMC). This important secretory product of POMC was shown to possess an interesting aldosterone-stimulating activity on a human adrenal aldosteronoma. It is O-gly...
متن کاملProcessing of pro-opiomelanocortin-derived amidated joining peptide and glycine-extended precursor in monkey pituitary.
The molecular forms of proopiomelanocortin (POMC) derived amidated and C-terminal glycine-extended joining peptide from monkey (Macaca mulatta) pituitary were determined. The predominant forms of joining peptide found were the low molecular peptides POMC(76-105) and POMC(76-106), respectively. Significant amounts of N-terminally truncated POMC(78-105) and POMC(78-106) were also detected in the ...
