New UK study helps scientists understand melanoma development
Date:7/15/2014

ociate Professor and the Drury Pediatric Research Endowed Chair at UK's Markey Cancer Center. "If you happen to be born with a problem in this MC1R hormonal pathway, then you need to be extra careful with respect to UV safety."

A good indication of a person's MC1R status is what happens to the skin after sun exposure.

"If you tan well, then your MC1R probably works well," D'Orazio said. "If you tend to burn, then you may have inherited a problem with your MC1R, and you probably should avoid purposeful UV exposure like tanning bed use or unprotected sun exposure."

D'Orazio and his research team found an important molecular link between MC1R signaling and DNA repair in their study. The team hopes to use this information to develop new melanoma-preventive treatments, like additives that can be included in sunblocks to ramp up the skin's ability to deal with UV damage.

Melanoma incidence has increased steadily over the past few decades in the 1930s, an estimated one in every 1,500 Americans developed the diseases. Today, the odds are about one in every 60. Having a problem with the MC1R pathway raises a person's lifetime risk of melanoma about four-fold.
