US scientists William G Kaelin Jr and Gregg L Semenza shared the 2019 Nobel Prize for Physiology or Medicine with UK scientist Peter J Ratcliffe.
The honour was accorded for discovering how cells sense and adapt to the availability of oxygen, the Nobel committee announced in a statement on Monday.
The research is leading to discoveries of new ways to tackle anaemia and cancer among other diseases.
‘The discoveries made by this year’s Nobel Prize laureates have fundamental importance for physiology and have paved the way for promising new strategies to fight anaemia, cancer and many other diseases,’ the Nobel Prize committee said.
The prize money for the award is 9 million Swedish crowns ($913,000).
Last year’s prize was shared by James P Allison, professor at the University of Texas and Tasuku Honjo of Kyoto University, Japan, for discoveries that led to a new cancer therapy that uses the body’s immune system to attack tumours.
The Nobel, an annual prize, awarded since 1901, recognises scientists who have made the most important discoveries for the benefit of mankind.
Medicine is the first of the Nobel Prizes awarded each year.
