Biography
William George Kaelin Jr., born in New York City in 1957, is a highly influential cancer researcher. He got his medical degree from Duke University in 1982 and completed his internal medicine residency at Johns Hopkins Hospital. After his clinical training, Kaelin started research training at Johns Hopkins with Bert Vogelstein, focusing on cancer genetics and tumor suppressor genes.
In 1992, Kaelin set up his own research lab at the Dana-Farber Cancer Institute and Harvard Medical School, where he has worked ever since. His pioneering work has focused on how cells detect and react to oxygen availability, which is a core biological process with big implications for cancer development and treatment. His research team discovered key mechanisms by which the von Hippel-Lindau (VHL) tumor suppressor protein controls how cells respond to low oxygen.
Kaelin's major contributions include explaining the molecular path that allows cells to sense oxygen levels and adjust their metabolism. His work showed how the VHL protein targets hypoxia-inducible factors (HIFs) for break down when oxygen is normal, and how this system goes awry in certain cancers. This research gave important insights into how cancer cells survive in low-oxygen environments and keep growing.
In 2019, Kaelin shared the Nobel Prize in Physiology or Medicine with Gregg Semenza and Peter Ratcliffe for their discoveries about how cells sense and adjust to oxygen availability. The Nobel Committee acknowledged their work as crucial for understanding both normal physiology and diseases, especially cancer and anemia. In addition to the Nobel Prize, Kaelin has received many scientific awards and continues to lead research that connects basic cell biology with clinical approaches to cancer treatment.
Before Fame
Growing up in New York City during the 1960s and 1970s, Kaelin experienced a time of rapid growth in molecular biology and cancer research. This era introduced recombinant DNA technology and first identified oncogenes, paving the way to understanding cancer as a genetic disease.
Kaelin's journey to scientific success began when he decided to combine clinical medicine with research. After finishing medical school at Duke University, he trained at Johns Hopkins, known for its strong focus on cancer research. Under the guidance of Bert Vogelstein, who was leading work on tumor suppressor genes, Kaelin laid the groundwork for his later breakthroughs in cellular oxygen sensing mechanisms.
