2019 Nobel Prize in Physiology or Medicine Announced for Discoveries on How Cells Adapt to Oxygen



The 2019 Nobel Prize in Physiology or Medicine honored work on understanding how cells adjust to low oxygen levels.

hree scientists who worked independently — William G. Kaelin, Jr. of the Dana-Farber Cancer Institute, Peter J. Ratcliffe of the University of Oxford and Gregg L. Semenza of Johns Hopkins University — were awarded the 2019 Nobel Prize in Physiology or Medicine this morning for their research into one of the adaptive mechanisms most important to the survival of life. The three scientists uncovered how cells sense and respond to the availability of oxygen, that key ingredient needed for complex organisms to build tissues, move and perform the diverse jobs that keep them alive.
