The Melanocyte-Stimulating Hormones
1962Publisher Summary From a research standpoint the subject of hormonal control of pigmentation is only forty-six years old. It began when two biologists, P. E. Smith and B. M. Allen independently and at the same time, found that removing the pituitary glands of tadpoles and frogs produced marked lightening in the color of their skin.

A radioimmunoassay for γ-melanocyte stimulating hormone
Life Sciences, 1980A specific radioimmunoassay for ..gamma..-melanocyte stimulating hormone-like peptides was developed. An antiserum raised in rabbit to synthetic bovine ..gamma../sub 3/-MSH, one of the possible ..gamma..-MSH peptides, specifically recognizes the portion between His/sup 5/ and Arg/sup 14/ of ..gamma../sub 3/-MSH without significant cross-reaction with ...

Melanocyte-Stimulating Hormone and Adrenocorticotrophic Hormone
New England Journal of Medicine, 1964HYPERPIGMENTATION in patients with adrenocortical insufficiency or some kinds of pituitary tumors is produced by increased release from the pituitary gland of peptide hormones that cause melanocytes to darken.1 2 3 These peptides are the melanocyte-stimulating hormones (alpha and beta MSH) and adrenocorticotrophin (ACTH). The background of this subject

Endocrinology, 1979
Pseudopregnancy (PSP) was induced in rats by vaginal stimulation and the levels of MSH in serum and pituitary were examined. One hour after vaginal stimulation, the serum MSH level was increased, and a cyclical variation was observed by the second day of PSP. There were two surges of about 50 pg/ml, one in the morning and the other at night.

A RADIOIMMUNOASSAY FOR β-MELANOCYTE-STIMULATING HORMONE IN HUMAN PLASMA
Journal of Endocrinology, 1973SUMMARY A method is described for the radioimmunoassay of β-melanocyte-stimulating hormone (β-MSH) in human plasma. It was capable of detecting 20–30 pg β-MSH and was unaffected by the presence of α-MSH and human adrenocorticotrophic hormone. However, cross-reactivity did occur with β-glutamyl MSH (porcine).

Melanocyte-stimulating hormone and adaptive behaviour.
Ciba Foundation symposium, 1981In order to study the physiological role of alpha-MSH in adaptive behaviour, plasma concentrations of alpha-MSH were measured during acquisition and extinction of active avoidance behaviour and during retention of a passive avoidance response.

The evolution of vertebrate corticotrophin and melanocyte stimulating hormone
General and Comparative Endocrinology, 1975Abstract ACTH and β-LPH appear to be synthesised in both the pars distalis and the pars intermedia. In the pars distalis they are secreted intact. In the pars intermedia ACTH acts as the precursor of α-MSH and CLIP, and β-LPH acts as the precursor for γ-LPH and β-MSH. α-MSH, CLIP and β-MSH do not exist in significant amounts in the human pituitary. α-

Biological actions of melanocyte-stimulating hormone.
Ciba Foundation symposium, 1981Melanocyte-stimulating hormone (alpha-melanotropin, MSH) may function in a number of diverse physiological roles. MSH stimulates (1) rapid translocation of melanosomes (melanin granules) in dermal melanophores to effect rapid colour change and (2) melanogenesis in normal and abnormal (melanoma) epidermal melanocytes.
