Nobel Prize Winner in Medicine named
The Nobel Prize in Medicine was given for the discovery of cellular "self-eating"
The Nobel Prize in Physiology or Medicine was awarded to Yoshinori Osumi for revealing the mechanism of autophagy, the process of recycling unnecessary parts of a cell inside lysosomes or vacuoles, representatives of the prize committee said at a ceremony at the Karolinska Institute in Stockholm.
Yoshinori Osumi is a biologist from the Tokyo University of Technology, who has studied the mechanisms of cellular autophagy all his life. The phenomenon of autophagy itself was discovered in the 1960s, but the principles of autophagy remained unknown until the 90s of the last century, when Osumi was able to reveal its secrets by observing the growth of thousands of yeast cultures that had some genes associated with autophagy removed inside their vacuoles.
"Thanks to Osumi's work, we now know what role autophagy plays in the development of the embryo, in the origin of cancer, the development of many diseases and in the aging of the body, how lysosomes and autophagosomes arise," said Maria Masucci, a member of the Nobel Committee.
Last year, the prize in the field of physiology and medicine was awarded, unlike this year and the previous five years, for a practical discovery – for the development of new methods of combating parasitic worms and malaria. It was received by William Campbell (USA), Satoshi Omura (Japan) and Tu Yu (China).
The award ceremony of the presented laureates will be held traditionally in Stockholm on December 10, the day of the death of the founder of the Nobel Prizes – the Swedish entrepreneur and inventor Alfred Nobel (1833-1896). The amount of the award this year is 8 million Swedish kronor (953 thousand dollars).
