Growth hormone secretagogue receptor secretagogue receptor is activated, a variety of different intracellular signaling cascades can result, depending on the cell type in which the receptor is expressed. These intracellular signaling cascades include mitogen-activated protein kinase (MAPK)), protein kinase A (PKA), protein kinase B (PKB), also known as AKT), and AMP Activated Protein Kinase (AMPK) cascades. It is well-characterized that activating the growth hormone secretagogue receptor with ghrelin induces an orexigenic state, or general feeling of hunger. However, ghrelin may also play a role in behavioral reinforcement. Studies in animal models, found that food intake increased when ghrelin was specifically administered to just the
Adrenocorticotropic hormone (medication) Adrenocorticotropic hormone (medication) Adrenocorticotropic hormone is used as a medication and as diagnostic agent in the ACTH stimulation test. The form that is purified from pig pituitary glands is known as corticotropin (INN, BAN) is a medication and naturally occurring polypeptide tropic hormone produced and secreted by the anterior pituitary gland. The form that is made synthetically is tetracosactide (INN), also known as tetracosactrin (BAN) and cosyntropin (USAN), and the acetate ester, tetracosactide acetate (JAN), also known as tetracosactrin acetate (BAN). It consists of the first 24 (of a total of 39) amino acids of ACTH and retains full function
