The best known anti-cancer protein also promotes tanning
The protein not only protects against skin damage by activating the dimming, but also produces endorphins that may be associated with feelings of pleasure in sunbathing.
A protein known for its anticancer function, the protein p53, also promotes skin tanning in response to ultraviolet light received from the sun, a mechanism that appears to inhibit the development of melanoma, the type most common skin cancer, according to a Cancer Institute study of the Dana-Farber in Boston (USA). The research findings, published in the journal Cell.
In a previous study, published last year, researchers found that ultraviolet radiation from the sun causes the keratinocytes produce and secrete a hormone called alpha-MSH which causes the production of melanin by melanocytes. The mechanisms of action that occur in the keratinocytes to lead to the production of alpha-MSH, however, were unknown.
Researchers already knew that alpha-MSH is created when another protein, known as pro-opiomelanocortin (or POMC) decompose. They also knew that the amount of POMC in cells rose sharply when exposed to ultraviolet rays, but did not know what he was doing to increase POMC.
