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 کاملFatty acid oxidation in human skeletal muscle.
In this issue of the JCI, Rasmussen et al. (1) describe the functional regulation of fatty acid oxidation by hyperglycemia and hyperinsulinemia in human skeletal muscle. The authors report inhibition of long-chain fatty acid (LCFA) oxidation, but not medium-chain fatty acid (MCFA) oxidation, in association with increased intramyocellular malonyl-CoA concentrations. Normally, a glucose infusion ...
متن کاملRegulation of fatty acid oxidation in skeletal muscle.
Researchers using animals are beginning to elucidate the control of fatty acid metabolism in muscle at the molecular and enzymatic level. This review examines the physiological data that has been collected from human subjects in the context of the proposed control mechanisms. A number of factors, including the availability of free fatty acids and the abundance of fatty acid transporters, may in...
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 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...
