description Harold Varmus Overview
Harold Varmus is an American physician and biomedical researcher who made significant contributions to the understanding of cancer genetics. Working alongside J. Michael Bishop at the University of California, San Francisco, he co-discovered that cancer-causing genes originate from normal cellular genes, known as proto-oncogenes. This 1989 Nobel Prize-winning discovery clarified the genetic mechanisms that drive tumor formation.
Varmus also served as the Director of the National Institutes of Health and later as the Director of the National Cancer Institute, overseeing major federal research initiatives.

help Harold Varmus FAQ
What did Harold Varmus discover about cancer-causing genes?
Harold Varmus, working alongside J. Michael Bishop at the University of California, San Francisco, discovered that cancer-causing genes (oncogenes) originate from normal cells. He proved that these genes are not foreign invaders but are actually normal cellular genes that have mutated or been hijacked by viruses.
Did Harold Varmus win a Nobel Prize for his cancer research?
Yes, Harold Varmus and J. Michael Bishop were jointly awarded the 1989 Nobel Prize in Physiology or Medicine. They received the prestigious award for their discovery of the cellular origin of retroviral oncogenes.
Did Harold Varmus serve in any prominent government or administrative medical roles?
In addition to his research, Varmus served as the Director of the National Institutes of Health (NIH) under President Bill Clinton. He later became the President of Memorial Sloan Kettering Cancer Center in New York and the Director of the National Cancer Institute.
What virus did Harold Varmus study to make his oncogene discovery?
Varmus and Bishop studied the Rous Sarcoma Virus (RSV), a retrovirus that causes cancer in chickens. They discovered that the virus's cancer-causing gene (src) was actually derived from a normal gene found in the host chicken cells.
