Molecular switch prevents cell damage caused by UVB rays from sunlight
ScienceDaily (2010-06-15) -- The protein Nrf2 plays a crucial role in tissue repair and in the protection against carcinogenesis. Cell biologists have now discovered a previously unknown role for this molecular switch, which activates numerous genes that protect cells from stress: it prevents cell damage in the skin caused by UVB rays from the sunlight. In addition, they unraveled the underlying mechanisms of action. ... > read full article
