α-Melanocyte-Stimulating Hormone

JAMA, 1991
"Black Skin or White? Science Offers a Choice" was the premature headline for an article written in 1980. 1 Even in 1991, science has not provided individuals with the ability to lighten, darken, or modify the hue of their skin. Tanning by exposure to sunlight or to artificial sources of ultraviolet radiation darkens skin but is considered dangerous ...

α MELANOCYTE STIMULATING HORMONE INDUCES GONADOTROPIN RELEASE

The Journal of Clinical Endocrinology & Metabolism, 1981
The present study demonstrates that synthetic alpha-MSH given as a 2.5 mg intravenous bolus induces an unequivocal rise in LH and FSH in male subjects but not in female subjects during the low estrogen phase of the cycle.

Neuropharmacological tests with α-melanocyte stimulating hormone

Life Sciences, 1976
Abstract The pituitary peptide hormone α-MSH was found to potentiate the behavioral effects of DOPA but not serotonin. It slightly reduced footshock-induced fighting and decreased audiogenic seizures in susceptible mice, but was inactive in reducing the tremors induced by oxotremorine.

The Melanocyte-Stimulating Hormones

1962
Publisher 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.

Melanocyte-stimulating hormones from sheep pituitary glands

Biochimica et Biophysica Acta, 1963
Abstract The melanocyte-stimulating hormones, α- and β-MSH were isolated from sheep pituitary glands. Ovine α-MSH was found to have the same amino acid sequence as α-MSH from other animals. Three varieties of β-MSH from sheep were studied. One appeared to be identical with bovine β-MSH.

A radioimmunoassay for γ-melanocyte stimulating hormone

Life Sciences, 1980
A 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 ...

Serum Melanocyte-Stimulating Hormone Levels and Pituitary Melanocyte-Stimulating Hormone Content during Pseudopregnancy in the Rat*

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.

Behavioral Aspects of Melanocyte-Stimulating Hormone (MSH)

1973
Publisher Summary This chapter explores the behavioral aspects of melanocyte-stimulating hormone (MSH). The pituitary hormone MSH is tested in several different behavioral systems. MSH is a hormone(s) whose presence has persisted in the pituitary gland of vertebrates from very low forms to man.
