Oxygen sensing decoded: a Nobel concept in biology

AbstractOxygen is essential to most organisms as it is a necessity for aerobic metabolism and energy production. Too much or too little oxygen can be deadly, such that mechanisms for fast and titrated response to changing oxygen levels are crucial. These mechanisms have evolved from the studies ofGregg L. Semenza, William G. Kaelin andPeter J. Ratcliffe. It is through the work of their three laboratories, performed in the 1990s, that the cellular oxygen sensing mechanisms have been decoded. Their discoveries have had major impact for innovation in medicine, especially in the field of angiogenesis research, where oxygen sensing and its consequences have led to enhanced insight in vascular development and strategies for combating angiogenic diseases. On October 7, the Nobel Assembly in Stockholm announced at the Karolinska Institute that the Nobel Prize for Medicine 2019 is jointly awarded to these three scientists for their seminal discoveries on how cells sense and respond to oxygen.
