| “Oxygen is the lifeblood of living organisms,” said Dr. George Daley, dean of Harvard Medical School. “Without oxygen, cells can’t survive.” But too much or too little oxygen also can be deadly.

| The investigators uncovered detailed genetic responses to changing oxygen levels that allow cells in the bodies of humans and other animals sense and respond to fluctuations, increasing and decreasing how much oxygen they receive. | The investigators uncovered detailed genetic responses to changing oxygen levels that allow cells in the bodies of humans and other animals sense and respond to fluctuations, increasing and decreasing how much oxygen they receive. |
| The discoveries reveal the cellular mechanisms that control such things as adaptation to high altitudes and how cancer cells manage to hijack oxygen. Randall Johnson, a member of the Nobel Assembly, described the work as a “textbook discovery” and said it would be something students would start learning at the most basic levels of biology education. | The discoveries reveal the cellular mechanisms that control such things as adaptation to high altitudes and how cancer cells manage to hijack oxygen.

| The cancer “was really fascinating,” Dr. Kaelin said. It had unusual features, like causing the body to make a substance, vegF, that stimulates the formation of blood vessels. And the cancer can cause the body to make too many red blood cells by increasing the production of EPO. | The cancer “was really fascinating,” Dr. Kaelin said.

| He became a medical researcher almost by chance. “I was a tolerable schoolboy chemist and intent on a career in industrial chemistry,” he said in a speech in 2016. “The ethereal but formidable headmaster appeared one morning in the chemistry classroom. ‘Peter,’ he said with unnerving serenity, ‘I think you should study medicine’. And without further thought, my university application forms were changed.” | He became a medical researcher almost by chance. “I was a tolerable schoolboy chemist and intent on a career in industrial chemistry,” he said in a speech in 2016. “The ethereal but formidable headmaster appeared one morning in the chemistry classroom. ‘Peter,’ he said with unnerving serenity, ‘I think you should study medicine’.
