To fulfill his national service obligations during the Vietnam War, Varmus became a member of the commissioned corps of the Public Health Service, working as a Clinical Associate in the laboratory of
Ira Pastan at the
National Institutes of Health from 1968 to 1970. During this first period of laboratory research, he and Pastan and their colleagues described aspects of the mechanism by which the lac operon of E. coli is regulated transcriptionally by
cyclic AMP.[9] In 1970, he and his wife, Constance Casey, moved to San Francisco, where he began post-doctoral studies with
Michael Bishop at
University of California, San Francisco under a fellowship from the California Division of the American Cancer Society.[10] Appointed as an assistant professor in the UCSF Department of Microbiology and Immunology in 1972, he was promoted to professor in 1979 and became an American Cancer Society Research Professor in 1984.
During the course of his years at UCSF (1970 to 1993), Varmus's scientific work was focused principally on the mechanisms by which
retroviruses replicate, cause
cancers in animals, and produce cancer-like changes in cultured cells. Much of this work was conducted jointly with Michael Bishop in a notably long scientific partnership. Their best-known accomplishment[11] was the identification of a cellular gene (
c-Src) that gave rise to the
v-Srconcogene of
Rous sarcoma virus, a cancer-causing virus first isolated from a chicken
sarcoma by
Peyton Rous in 1910. Their discovery triggered the identification of many other cellular
proto-oncogenes—progenitors of viral oncogenes and targets for mutations that drive human cancers. Much of this work and its consequences are described in his Nobel lecture[12] and Bishop's,[13] in Varmus's book The Art and Politics of Science,[10] and in numerous histories of cancer research.[14][15]
Other significant components of Varmus's scientific work over the past four and a half decades include descriptions of the mechanisms by which retroviral DNA is synthesized and integrated into chromosomes;[16][17] discovery of the
Proto-oncogene Wnt-1 with
Roel Nusse;[18][19] elucidation of aspects of the replication cycle of
hepatitis B virus (with Donald Ganem[20]); discovery of ribosomal frameshifting to make retroviral proteins (with
Tyler Jacks[21]); isolation of a cellular receptor for avian retroviruses (with John Young and Paul Bates[22]); characterization of mutations of the
epidermal growth factor receptor gene in human
lung cancers, including a common mutation that confers drug resistance (with
William Pao[23]); and generation of numerous mouse models of human cancer. Notably, Varmus continued to conduct or direct laboratory work throughout his service in leadership positions at the NIH, MSKCC, and NCI.
Politics and government service
In the early 1990s, following the award of their Nobel Prize, Varmus and Bishop became active in the politics of science, working principally with UCSF colleagues Bruce Alberts and Marc Kirschner, and with the Joint Steering Committee (later renamed the Coalition for the Life Sciences).[24] He also co-chaired Scientists and Engineers for Clinton-Gore during the 1992 presidential campaign.
National Institutes of Health directorship
After the resignation of NIH Director Bernadine Healy in April, 1993, Varmus was nominated for the post by President William J. Clinton in July, and confirmed by the Senate in November. As the NIH director, Varmus was credited with helping to nearly double the research agency's budget; but his tenure was also noted for appointments of outstanding scientists to serve as Institute Directors; for excellent relationships with members of Congress and the Administration; for leadership on clinical and AIDS research; for policy statements about stem cell research, cloning of organisms, gene therapy, and patenting; for promoting global health research, especially on malaria; and for construction of new facilities, including a new Clinical Center and a Vaccine Research Center at the NIH.[25]
Between directorships
Varmus supported the presidential candidacies of Al Gore (2000) and John Kerry (2004). During the George W. Bush presidency, he gave lectures critical of the Administration's science policies.[26] But he has also written a laudatory account of PEPFAR (the President's Emergency Plan For AIDS Relief), Bush's initiative to combat AIDS globally.[27]
Varmus declared his support for Barack Obama's quest for the presidency early in 2008[28] and chaired the campaign's Science and Technology Committee. Following Obama's election, he was named by the president-elect as one of three co-chairs of PCAST (the
President's Council of Advisors on Science and Technology).[29] He resigned from that post to assume the directorship of the
National Cancer Institute (NCI) on July 12, 2010, after being named to the post by President Obama.[30]
National Cancer Institute directorship
On May 17, 2010, the White House announced that Varmus would become the 14th Director of the NCI, making him the first person to have served as director of an individual NIH Institute after being director of the entire NIH. In this capacity, despite diminishing budgets at all the Institutes including NCI, he started new administrative centers for cancer genomics and global health; initiated novel grant programs for "outstanding investigators," for "staff scientists," and for addressing "Provocative Questions."[31][32] He also renamed the
Frederick National Laboratory for Cancer Research and started an initiative there to study RAS oncogenes.[33]
On March 4, 2015, Varmus submitted his resignation to the president, effective March 31, 2015, announcing his intention to return to New York City as the Lewis Thomas University Professor of Medicine at Weill Cornell Medicine and as a senior associate at the New York Genome Center.[34][35] Deputy NCI Director Douglas Lowy became acting director of the NCI on April 1, 2015.
During his tenure as NCI Director, Varmus took the unusual step of co-authoring with three non-governmental colleagues a critique of several practices prevalent in the biomedical research community.[36] That essay has been the starting point for several subsequent efforts to reduce the hypercompetitive atmosphere in biomedical research.[37]
Presidency of Memorial Sloan Kettering Cancer Center
After leaving the NIH Directorship at the end of 1999, Varmus became the president and CEO of Memorial Sloan-Kettering Cancer Center in New York City on January 1, 2000. During his ten and a half years at MSKCC, he was best known for enlarging the basic and translational research faculty; building a major new laboratory facility, the Mortimer E. Zuckerman Research Center; starting a new graduate school for cancer biology (the Louis V. Gerstner Jr. Graduate School of Biomedical Sciences); overseeing renovation and construction of many clinical facilities; and leading a major capital campaign.[38][39] He also continued to run an active laboratory and to teach as a Member of the Sloan-Kettering Institute. On January 12, 2010, MSKCC reported that Varmus had asked the MSKCC Boards of Overseers and Managers "to begin a search for his successor." He left MSKCC on June 30, 2010, shortly before assuming the NCI directorship.
Publication practices in science
Near the end of his tenure as NIH director, Varmus became a champion of ways to more effectively use the Internet to enhance access to scientific papers.[40][41] The first practical outcome was the establishment, with David Lipman of the
National Center for Biotechnology Information at NIH, of
PubMed Central, a public digital library of full-length scientific reports;[42] in 2007, Congress directed NIH to ensure that all reports of work supported by the NIH appear in PubMed Central within a year after publication.[43] Varmus and two colleagues, Patrick Brown at Stanford and Michael Eisen at UC Berkeley, were co-founders and leaders of the board of directors of the
Public Library of Science (PLOS), a not-for-profit publisher of a suite of open access journals in the biomedical sciences.[44]
Advisory roles
Varmus has been a frequent advisor to the US government, foundations, academic institutions and industry. Currently, he serves as a member of the Secretary of Energy's advisory board, the Global Health Advisory Board at the
Bill and Melinda Gates Foundation, the board of directors of the International Biomedical Research Alliance,[45] the
Lasker Foundation Prize Jury, and the Scientific Advisory Board of the
Broad Institute at Harvard and MIT, and he chairs advisory groups for the
Faculty of 1000 and the Global Alliance for Genomics and Health. In the past, he was chairman of the Grand Challenges in Global Health at the Gates Foundation,[46] a member of the
World Health Organization's Commission on Macroeconomics and Health,[47] and an advisor to
Merck & Co.,
Chiron Corporation,
Gilead, and
Onyx Pharmaceuticals. He has been chair of the
World Health Organization's Science Council since its founding in 2021[48]
Varmus has criticized the high cost of many modern cancer drugs, which create barriers to treatment. He advocates for the genetic testing of cancers as a routine reimbursed procedure, and for wider use of the information that genetic testing of cancer can provide. He argues that widespread use of panel tests and exome analyses to identify cancer-causing mutations would be simpler and cheaper than full genome analysis. He has argued for the coverage of such services under Medicare and Medicaid on the grounds of Coverage with Evidence Development, since the data could be used to better evaluate test and treatments. He supports the creation of a database of information that can be correlated with clinical outcomes for use by all oncologists. He is hopeful that researchers will soon use new technologies to move beyond the study of primary tumors, where they have had considerable success, and explore how cancer initiates and the development of
metastasic cancers.[10]
Varmus has been married since 1969 to Constance Louise Casey, a journalist and science writer. They live on Manhattan's Upper West Side and have two sons: Jacob, a jazz trumpet player and composer who lives in Queens, and Christopher, a social worker who lives in Brooklyn. Varmus and Jacob have performed a series of lecture-concerts entitled "Genes and Jazz" at the Guggenheim[56] and
Smithsonian Museums, the
Boston Museum of Science, the
John F. Kennedy Center for the Performing Arts and the South Asian Summer Festival in Vancouver.
