From September 1941 to January 1944, the three million inhabitants of Leningrad was under siege. Hunger and disease were accompanied by the city throughout the war. For the period of the blockade of 1.5 million people died from lack of food, the rest of the half managed to survive in these conditions. Scientists from the research Institute of obstetrics, gynecology and reproduction, named after D. O. Ott in St. Petersburg tried to answer the question, what was the strength of the survivors.
The scientists examined blood samples of people who survived the blockade. They obtained data were compared with blood samples from people who lived during the war in more mild conditions.
The residents of besieged Leningrad mutations that define slow metabolism, met a third more often than the control group. Slow metabolism allows for longer to save energy during low caloric intake. This has helped many people to experience hunger, consider genetics.
Mutation of the protein UCP3 and changes in receptor PPAR-alpha and PPAR-Delta has made the life of people, energy is not consumed, and are maintained by the body for the future. Scientists plan to continue research and to use the collected information in the fight against anorexia and diseases of metabolism.
