| melanotropin | A polypeptide hormone secreted by the intermediate lobe of the hypophysis in humans (in neurohypophysis in certain other species) which causes dispersion of melanin by melanophores, resulting in darkening of the skin, presumably by promoting melanin synthesis; this effect is readily demonstated in some lower vertebrates, such as frogs and fish; alpha-melanotropin is an N-acetylated peptide with 13 amino acids; beta-melanotropin has 22 amino acids. Synonym: intermedin, melanocyte-stimulating hormone, melanophore-expanding principle. (05 Mar 2000) |
| melanotropin release-inhibiting hormone | Inhibits synthesis and release of melanotropin. Synonym: melanotropin release-inhibiting hormone. Origin: melanotropin + G. States, stationary, + -in (05 Mar 2000) |
| melanotropin-releasing factor | A hexapeptide similar to oxytocin; it stimulates the release of melanotropin. Synonym: melanotropin-releasing factor, melanotropin-releasing hormone. Origin: melanotropin + L. Libero, to free, + -in (05 Mar 2000) |

| melanuria | The excretion of urine of a dark colour, resulting from the presence of melanin or other pigments or from the action of phenol, creosote, resorcin, and other coal tar derivatives. Origin: melano-+ G. Ouron, urine (05 Mar 2000) |

| melanomas |
The most serious and least common form of skin cancer. Melanomas usually grow out of moles (dark raised areas) in the skin cells (called melanocytes) that produce pigment, and can spread to the internal organs. Although people can die from melanoma, it can be easily identified and if caught early, can be treated.
