A team led by researchers from Nagoya University in Japan has discovered new pathways that cells use to repair themselves following exposure to ultraviolet (UV) light, and a new agent involved in these pathways known as RFWD3. This could lead to future treatments for people with photosensitive diseases and prompt the development of better anticancer medicines. "We believe our findings provide a new perspective to the field of DNA damage response and also to cell biology," said lead author, Chikahide Masutani. They published their research in the journal Life Science Alliance.
