Masonic Cancer Center researchers discover a virus-fighting enzyme
It’s well known that sunlight and chemical carcinogens can mutate DNA, and that mutations are essential for cancer to develop.
One big mystery was what causes the thousands of mutations evident in most breast cancers.
Now researcher Reuben Harris, Masonic Cancer Center, University of Minnesota, and his colleagues have found evidence that one of our own proteins is a major source of these mutations. The researchers have just published evidence implicating the protein—an enzyme called APOBEC3B—in the international journal Nature. (more…)
