Bishop, J(ohn) Michael (sh)




born Feb. 22, 1936, York, Pa., U.S.

U.S. virologist.

He graduated from Harvard Medical School. In 1970 he and Harold Varmus tested the theory that healthy body cells contain oncogenes (cancer-causing genes). Further research showed that such genes can cause cancer even without viral involvement. By 1989, the year Bishop and Varmus shared a Nobel Prize for their research, scientists had identified more than 40 oncogenes in animals.
