Damage to cell DNA by UV light can cause skin cancer. Professor Kaoru Sugasawa, a member of the Biosignal Research Center at Kobe University, has contributed to a breakthrough study on accessing and repairing UV-damaged DNA, in collaboration with colleagues from the Friedrich Miescher Institute for Biomedical Research in Switzerland, Osaka University and the University of Tokyo.

Professor Sugasawa comments: “During a long history of studies on DNA repair, it has been a kind of enigma how chromatin structures can be changed so that DNA lesions become accessible to sensor proteins. This study provides us with a new and important insight into this issue, because UV-DDB can interact with sites of UV-induced DNA damage buried in chromatin by altering the nucleosome structure without the aid of any other factors. This greatly contributes to our understanding of how we are protected from the deleterious effects imposed by UV radiation, especially skin cancer.”
