A British doctor who graduated from Cambridge University is among the three people who won the Nobel Prize in medicine.
Sir Peter J Ratcliffe was named winner of the prestigious award, along with Americans William G Kaelin Jr and Greg L Semenza for their "discoveries about how cells feel and adapt to oxygen availability."
The trio will split the prize money of the nine million kronor prize (£ 738,000).
Sir Ratcliffe teaches at Magdalen College at Oxford University, having studied medicine at Cambridge University.
The trio's findings "are of fundamental importance to physiology and paved the way for promising new strategies to combat anemia, cancer and many other diseases," according to the Karolinska Institute's Nobel Assembly.
Professor Randall S Johnson, a member of the Nobel Assembly, explained how the results would affect people's lives and health:
"(The findings) will really help us and are already helping people develop new medicines.
"Finding different ways to influence this fundamental process has already proved potentially very useful in very clear medical applications," he said.
The announcement was made during a ceremony in Sweden, presented by Thomas Perlmann, secretary of the Nobel Committee.
It is the 110th Nobel Prize in Physiology or Medicine, awarded since 1901.
