Reinforcing Sunscreen Lotions With Caffeine
“Scientists have worked out how caffeine might protect against certain skin cancers – a finding that could lead to better sunscreens.
The research, conducted in mice, suggests that caffeine changes the activity of a gene involved in the destruction of cells that have DNA damage and are therefore more likely to become cancerous. The scientists said this may lead to new ways of preventing skin cancer, though other experts cautioned that it did not mean coffee lovers were better protected against the disease…
The overall protective role of caffeine against cancers has been noted in previous studies, but Allan Conney of the department of chemical biology at Rutgers University in New Jersey wanted to find the specific molecular mechanisms behind it.
He suspected that the response might involve a gene called ATR, which is suppressed when caffeine molecules are around. This suppression encourages the death of DNA-damaged cells.”
