Exposure to UV radiation triggers DNA lesions that can lead to skin cancer, the most common type of cancer in the United States. Previous studies in mice have shown that levels of a protein called XPA, involved in repairing UV-induced DNA lesions, waxes and wanes with the time of day. Shobhan Gaddameedhi et al. found that the protein's level and activity in mouse skin cells are at their lowest at 4 AM and their highest at 4PM.

National Cancer Institute-funded center to study proteins for better cancer diagnosis, treatment

The University of North Carolina at Chapel Hill, Washington University School of Medicine in St. Louis, and Boise State University have been named partners in one of five US centers that will use genetic data to search for proteins that are abnormally made by cancer cells. The partnerships form the new Clinical Proteomic Tumor Analysis Consortium (CPTAC) supported by the National Cancer Institute (NCI).
