Caffeine Protects Against Sun Damage and Cancer
Caffeine in your sunscreen? You’ve likely been putting it on for several years and didn’t know it. Scientists worked out how caffeine protects against certain types of skin cancers, which has already lead to better sunscreens.
Professor of Pharmacy Allan Conney at Rutgers University found that the specific anticancer molecular mechanism involves a gene called ATR (Ataxia telangiectasia and Rad3-related), which is suppressed by caffeine molecules. Apparently, dampening ATR activity promotes apoptosis, or the death of DNA-damaged cells. These findings may lead to new ways of preventing skin cancer. (more…)
