Re: Harvard / Dana-Farber Cancer Institute Study: Tanning Protects Against Skin Cance
"Tanning Addiction" Explained.
Quote:
There is even the possibility that p53 protects against skin damage in a second — and previously unsuspected — way. The protein not only causes skin to tan in response to sunlight, it may also underlie people's desire to spend time in the sun.
The same process that causes POMC to produce α-MSH also leads to the production of β-endorphin, a protein that binds to the body's opiate receptors and may be associated with feelings of pleasure. "Even as p53 is causing skin to tan during sunlight exposure, it may also affect neuronal circuits," Fisher says. "These proteins may provide an explicit link between the regulation of tanning and of mood.
