• Biological functions: α-MSH and other MSH peptides are associated with a wide spectrum of biological functions through MC receptors that distribute in many tissues. MC1R is expressed in melanocytes, keratinocytes, macrophages, leukocytes, and adipose tissue; MC3R is expressed in the central nervous system (CNS), kidney, testis, ovary, skeletal muscle, placenta, and mammary gland; MC4R is expressed in the CNS and associated with food intake; and MC5R is expressed in exocrine glands, muscle, and the CNS. The representative physiological functions of MSH peptides mediated by MC receptors are stimulation of melanocytes in the skin to synthesize melanin, including regulation of the eumelaninpheomelanin switch via MC1R; energy homeostasis and natriuresis via MC3R; energy homeostasis and erectile function via MC4R; and synthesis and secretion of exocrine gland products via MC5R.
• Description: A pituitary hormone secreted from the pars intermedia, MSH was one of the first adenohypophysial hormones demonstrated to be present in vertebrates, from jawless fish to mammals, together with adrenocorticotropic hormone (ACTH). The fact that MSH is derived from a precursor protein called proopiomelanocortin (POMC) was demonstrated in 1979, using the pars intermedia from the bovine pituitary.
• Uses: alpha-Melanocyte Stimulating Hormone amide is an endogenous melanocortin receptor agonist (Ki values are 0.12, 31, 660 and 5700 nM for MC1, MC3, MC4 and MC5 receptors respectively). Anti-inflammatory peptide; antagonizes proinflammatory mediators, including TNF-α, IL-6 and NO and induces anti-inflammatory cytokine IL-10. Inhibits food intake and induces penile erections following i.c.v. administration.
• Clinical Use: The measurement of the blood concentration of MSH has not been validated for routine clinical use. MSH analogs have recently been developed for antiobesity medication, treatment of skin diseases, and prevention of actinic keratoses in organ transplant recipients. The potential use of radiolabeled α-MSH peptides in melanoma imaging and the treatment of disseminated disease has also been reported.
