Biochem/physiol Actions

Adrenocorticotropic hormone (ACTH) is a polypeptide hormone thatstimulates adrenocortical activity. It is produced by the prohormoneproopiomelanocortin (POMC), which is synthesized in the corticotroph andmelanotroph cells found in the intermediate and anterior lobe of the pituitarygland and the arcuate nucleus of the hypothalamus. ACTH is also synthesized inthe skin. It plays a role in controlling steroidogenesis in the adrenal glandand prevents reactive oxygen species (ROS)-induced cell toxicity. Higher levelsof ACTH lead to skin hyperpigmentation due to the hyperstimulation ofmelanocytes, characteristic of primary adrenal insufficiency (PAI). Deficiencyof ACTH synthesis, receptors, or signaling is associated with adrenalinsufficiency.

Synthetic bovine parathyroid hormone containing the 1-34 NH2 terminal amino acids [bPTH-(1-34)] is capable of inhibiting stimulated uterine contraction. The purpose of the present investigation is to determine whether the inhibitory action of bPTH-(1-34) is a direct action of the

Extracts of porcine anterior pituitary contain several corticotrophic variants of ACTH 1-39. They were isolated by adsorption chromatography, ion-exchange chromatography and reverse-phase high-performance liquid chromatography. Four variants were then identified as starting and ending at positions corresponding to ACTH 1-38

The utility of matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry for the analysis of C-terminal peptide ladders from carboxypeptidase Y (CPY) digestions is discussed. MALDI analysis of aliquots of an optimized time-dependent CPY digestion of ACTH 7-38 fragment allowed for

Vasoactive intestinal peptide (VIP) concentration-dependently enhanced corticosterone and cyclic-AMP release by dispersed rat inner adrenocortical cells. A VIP-receptor antagonist and the ACTH-receptor antagonist corticotropin-inhibiting peptide annulled both adrenocortical-cell responses to VIP, while the protein kinase (PKA) inhibitor H-89 blocked only
