The identification of hundreds of genes involved in the formation and spread of cancer is leading to promising new methods for diagnosis, prevention, and treatment. In the case of colon cancer, researchers are developing genetic tests for detecting the cancer-causing mutations. Researchers are also investigating anti-cancer therapies that take advantage of the molecular differences between cancer cells and the normal cells surrounding them. In Dr. Vogelstein's lab, scientists are deploying specialized microbes to penetrate tumors, proliferate rapidly, and kill the cancer cells. - ResearchChannel is a nonprofit media and technology organization that connects a global audience with the research and academic institutions whose developments, insights and discoveries affect our lives and futures.
