William Kaelin's 2019 Nobel Prize in Physiology or Medicine

William G. Kaelin Jr., MD, won the 2019 Nobel Prize in Physiology or Medicine with two other physician-scientists for unraveling a molecular mechanism that not only is crucial to survival, but is entwined with cancer and other diseases.

Dr. Kaelin and his collaborators deciphered the core molecular events that explain how almost all multi-cellular animals tune their physiology to cope with varying quantities of life-sustaining oxygen in a unique signaling scheme. Their findings could lead to new therapeutics for a wide range of disorders — including cancer, cardiovascular disease, anemia, and macular degeneration.

How cells sense and adapt to oxygen levels

This oxygen-sensing mechanism involves the tumor-suppressor protein VHL, which is mutated in many kidney cancers, and proteins known as hypoxia inducible factors, HIF-1α and HIF-2α. Dr. Kaelin showed that HIF-2α drives certain kidney cancers and recently discovered how HIF-1α is hijacked by triple-negative breast cancers. He is developing therapeutic strategies for targeting these molecules and others implicated in cancer, such as mutated enzymes IDH1 and IDH2, with designer drugs.

Many honors for Dr. Kaelin

Dr. Kaelin's list of prestigious scientific awards, prizes, and honors is impressive — the cancer biologist having received the Stanley J. Korsmeyer Award (ASCI), the Foundation Lefoulon-Delalande Scientific Grand Prix, the Alfred Knudson Award in Cancer Genetics (NCI), the Canada Gairdner International Award, and election to the National Academy of Sciences.

More recently, Dr. Kaelin received the Massry Prize, the Lasker Award, the Science of Oncology Award (ASCO), the Princess Takamatsu Award (AACR), election to the AACR Academy, the Steven C. Beering Award, and the Wiley Prize in Biomedical Sciences.

About Dr. Kaelin's Lasker Award

The Nobel announcement comes just a few years after Dr. Kaelin and his collaborators won the 2016 Lasker Award — America's most prestigious biomedical honor, whose winners have often become Nobel laureates.
How cells and tissues sense changes in oxygen availability
Dr. Kaelin talks about how cells and tissues of the body sense and respond to changes in oxygen availability. In describing this molecular mechanism which, for example, enables the body to adapt to higher altitudes, Kaelin and his colleagues opened new avenues for treatments of heart disease and stroke.
