Carl Ronald Kahn (born January 14, 1944) is an American physician and scientist, best known for his work with insulin receptors and insulin resistance in diabetes and obesity. He is the Chief Academic Officer at Joslin Diabetes Center, the Mary K. Iacocca Professor of Medicine at Harvard Medical School [1] and a member of the National Academy of Sciences since 1999. [2]
Kahn was born in Louisville, Kentucky. He received his undergraduate and medical degree from the University of Louisville in 1964 and 1968. He became interested in pursuing diabetes research while serving in several positions at the National Institutes of Health (NIH) from 1970 to 1981. He moved to Boston in 1981 when he was appointed Associate Professor of Medicine at Harvard Medical School and Research Director of the Joslin Diabetes Center. By 1984, he was promoted to Professor of Medicine and named the Mary K. Iacocca Professor of Medicine at Harvard Medical School in 1986.
Kahn became the president and director of Joslin in 2000 and held this position until 2007. In 2012, he was appointed Joslin's first Chief Academic Officer. [3]
Outside of Joslin, Kahn also held various leadership roles. In 1998 he was appointed chair of the Congressionally-mandated Diabetes Research Working Group (DRWG). [4] This group developed a strategic plan which served as the roadmap for growth of the diabetes research for the United States over the following 10 years. Dr. Kahn also served as chair of Class IV (Biomedical Sciences) of the National Academy of Sciences from 2007 to 2010.
Kahn is married to Susan Becker Kahn, also formerly of Louisville. They have two children. Stacy Anne Kahn is a pediatric gastroenterologist at the Boston Children's Hospital. Jeffrey Adam Kahn is managing partner of Continuum Search based in Denver, Colorado. His brother Arnold Kahn was emeritus professor of developmental biology of the University of California San Francisco.
Kahn is an investigator in insulin signal transduction and mechanisms of altered signaling in diabetes. The main discoveries to come from his lab include the insulin receptor kinase, its two primary substrates and the molecular components of the insulin signaling network. Kahn's lab was also the first to define alterations in the signaling network in insulin resistant states, such as type 2 diabetes. [5] More recent discoveries from his lab encompass defining alterations in the signaling network in type 2 diabetes, including the important role of insulin action in unexpected tissues such as brain, both in physiologic regulation and potentially in development of Alzheimer's disease. His lab at Joslin has also made contributions to the understanding of obesity by showing that fat cells, called adipocytes, have different developmental origins and cellular functions that lead to risk of metabolic disease.
Kahn's work with adult humans has demonstrated that they have active brown fat that is central to redefining its role in metabolic regulation and protection from obesity. [6]
Sir Frederick Grant Banting was a Canadian medical scientist, physician, painter, and Nobel laureate noted as the co-discoverer of insulin and its therapeutic potential.
Bernardo Alberto Houssay was an Argentine physiologist. Houssay was a co-recipient of the 1947 Nobel Prize for Physiology or Medicine for discovering the role played by pituitary hormones in regulating the amount of glucose in animals, sharing the prize with Carl Ferdinand Cori and Gerty Cori. He is the first Latin American Nobel laureate in the sciences.
George Richards Minot was an American medical researcher who shared the 1934 Nobel Prize with George Hoyt Whipple and William P. Murphy for their pioneering work on pernicious anemia.
Joslin Diabetes Center is the world's largest diabetes research center, diabetes clinic, and provider of diabetes education. It is located in the Longwood Medical and Academic Area in Boston, Massachusetts, United States. Among the Harvard Medical School affiliated institutions, Joslin is unique in its sole focus on diabetes. Joslin has the world's largest team of board-certified physicians treating diabetes and its complications, as well as the largest staff of Certified Diabetes Educators anywhere in the world. Joslin also supports the world's largest diabetes research team with more than 40 faculty investigators and more than 300 researchers.
Elliott Proctor Joslin was the first medical doctor in the United States to specialize in diabetes and was the founder of today's Joslin Diabetes Center.
Jeffrey M. Friedman is a molecular geneticist at New York City's Rockefeller University and an Investigator of the Howard Hughes Medical Institute. His discovery of the hormone leptin and its role in regulating body weight has had a major role in the area of human obesity. Friedman is a physician scientist studying the genetic mechanisms that regulate body weight. His research on various aspects of obesity received national attention in late 1994, when it was announced that he and his colleagues had isolated the mouse ob gene and its human homologue. They subsequently found that injections of the encoded protein, leptin, decreases body weight of mice by reducing food intake and increasing energy expenditure. Current research is aimed at understanding the genetic basis of obesity in human and the mechanisms by which leptin transmits its weight-reducing signal.
JeffreyFlier is an American physician, endocrinologist, widely cited scientist, Higginson Professor of Medicine and Physiology, and Harvard University Distinguished Service Professor at Harvard Medical School. He was the 21st Dean of the Faculty of Medicine at Harvard University from 2007 to 2016.
George F. Cahill Jr. was an American scientist who significantly advanced the diabetes mellitus research of the 20th century. He focused on metabolic research, especially concerning human glucose metabolism in diabetic and normal conditions; he also investigated the effect of hunger and fasting on metabolic pathways and ketose processes. He was author and co-author of nearly 200 articles in scientific magazines and books.
Sir Stephen Patrick O'Rahilly is an Irish-British physician and scientist known for his research into the molecular pathogenesis of human obesity, insulin resistance and related metabolic and endocrine disorders.
José F. Caro, M.D. is an American physician, scientist, and educator most notable for his research in obesity and diabetes.
