Tanning found to protect against melanoma by releasing tumor suppressor protein: NewsTarget.com

There may be a relationship between the process that causes the body to tan and its defenses against skin cancer, according to a study conducted by scientists from the Dana-Farber Cancer Institute and published in the journal Cell. Tanning has actually been found to prevent cancer tumors.

Researchers found that when skin is exposed to sunlight, the body releases a protein called p53, a well-known tumor suppressor. A previous study by the same scientists found that when ultraviolet solar radiation strikes the skin, it also triggers the breakdown of the protein POMC, which in turn triggers the release of a hormone that produces melanin and causes the skin to darken (tan). When p53 was injected into skin cells, POMC production increased drastically.
