Scientists, by changing some genes of mice, were able to increase average life expectancy by 20%, which corresponds to 85-95 years man, writes The Daily Mail.
Scientists have carried out some operations with genes that result in reduced gene expression of mTOR, which is responsible for metabolism in the body and maintaining energy balance in the tissues. This experience acted differently on different organs and tissues. The nervous system including the brain, was not affected. Did not affect gene activity and the condition of the muscle tissue and body balance. However, mice with the mutated gene was experiencing problems with the bones, which quickly wore out and not enough recovered quickly. In addition, sharply decreased immunity, laboratory animals who have undergone the experience, often ill various types of infections.
It should be noted that the level of mTOR mice four times lower than in humans. The average lifespan of a mouse is about 30 months. Despite the fact that this is only the first steps in increasing life expectancy, the researchers have high hopes for the development of genetic engineering. In the future it will help to understand the nature and to save mankind from many age-related diseases.
