Newly discovered cellular process helps cells respond to DNA damage

Scientists at St. Jude Children’s Research Hospital have discovered a novel biochemical process that plays a critical role in helping cells in the body respond to DNA damage, such as that caused by exposure to radiation, environmental toxins or free radicals. The findings could lead to new approaches to prevent cancer, better ways to treat cancer and to the development of sensitive methods determining whether people have been exposed to radiation or environmental toxins, according to the researchers.
