Gregg L. Semenza, whose discoveries on how cells respond to low oxygen levels have the potential to result in treatments for a variety of illnesses, today was awarded the 2019 Nobel Prize in Physiology or Medicine by the Nobel Assembly at the Karolinska Institutet in Stockholm.
The academy recognized Semenza, the C. Michael Armstrong Professor of Medicine at the Johns Hopkins University School of Medicine, for his groundbreaking discovery of hypoxia-inducible factor 1, or HIF-1, the protein that switches genes on and off in cells in response to low oxygen levels.
