Desacetyl-α-melanocyte stimulating hormone and α-melanocyte stimulating hormone are required to regulate energy balance
OBJECTIVE Regulation of energy balance depends on pro-opiomelanocortin (POMC)-derived peptides and melanocortin-4 receptor (MC4R). Alpha-melanocyte stimulating hormone (α-MSH) is the predicted natural POMC-derived peptide that regulates energy balance. Desacetyl-α-MSH, the precursor for α-MSH, is present in brain and blood. Desacetyl-α-MSH is considered to be unimportant for regulating energy b...
متن کاملIsolation of melanocyte-stimulating hormone from hog pituitary gland.
The present communication is concerned with two substances possessing melanocyte-stimulating hormone (MSH) activity, ar-MSH and /3-MSH, found in hog pituitary gland. The main component, o(-MSH, was isolated by a four-step process consisting of solvent extraction and fractional precipitation, oxycellulose adsorption, counter-current distribution, and paper electrophoresis. a-MSH has been found t...
متن کاملPlasma α-melanocyte stimulating hormone predicts outcome in ischemic stroke.
BACKGROUND AND PURPOSE α-Melanocyte stimulating hormone (α-MSH) is an endogenously produced neuropeptide derived from the same precursor as adrenocorticotropic hormone. α-MSH has profound immunomodulatory properties and may also be neuroprotective. Nothing is known about α-MSH and changes in its plasma concentrations in patients with acute ischemic stroke. METHODS In this prospective observat...
متن کاملHormone of Middle Lobe of Pituitary Melanocyte Stimulating Hormones
The hormones secreted by intermediate lobe or middle lobe of pituitary gland are called melanocyte stimulating hormones or MSH. POMC is the precursor molecule which is cleaved by proteases to give ACTH and β-lipotropin. The ACHT is further cleaved to β-MSH which has 13 amino acids. There is also α-MSH which is present in larger quantities. Amino acids 11-17 of β-MSH are common to both α-MSH and...
متن کاملY2-Melanocyte-Stimulating Hormone
Peptides of the pro-opiocortin class produce pronounced cardiovascular and natriuretic actions. We have investigated the acute cardiovascular effects of one of the most potent members of this class, y2-melanocyte stimulating hormone (y2-MSH), in rats. Pressor actions of y2MSH administered systemicaMy were eliminated by ganglionic blockade with chlorisondamine. Peripheral cholinergic blockade fa...
