U of T researchers map role of Epstein-Barr virus in cancer

...sing because all other viruses that stimulate cell proliferation do it through p53. The question was why this one didn't. What our research shows is that EBNA1 does actually impact on the p53 protein; it just does it in a different way than other viruses do." Frappier, a Canada Research Chair in Molecular Virolog...
