The scientists were able to reverse the aging process

Ученые смогли обратить процесс старения

The researchers noted that experiments of this kind was held for the first time. In the course of the work used laboratory mice.

A group of scientists from the University of Alabama at Birmingham (USA) conducted the first study in the field of rejuvenation in animals with the restoration of mitochondrial function. In the course of work the specialists managed to wear out the mice, and then to rejuvenate them. The material on this subject was published in the journal Cell Death & Disease, writes

Scientists have made in the mitochondrial DNA of rodents mutation affecting the POLG gene, encoding the enzyme DNA polymerase gamma. This compound is localized in the mitochondria and it is involved in the replication and repair of mitochondrial DNA (mtDNA).

In the course of this work it was found that the damage POLG causes dysfunction of the mitochondria, specifically dysfunction of the oxidative phosphorylation. This, in turn, reduces storage of energy leads to the appearance of signs of aging – wrinkles and hair loss.

As a result, in the fertilized egg of mice has made an additional copy of the gene POLG mutation. DNA “driven” and began to participate the production of a polymerase in the presence of doxycycline is an antibacterial drug. This antibiotic began to add in food of mice, and within weeks they began to show signs of aging.

After doxicyclin expelled from the food, came the blocking activity of the mutant copies of POLG which in turn drew almost completely the symptoms of aging in rodents.

Earlier it was reported that scientists said about the death threat, which can carry loneliness.

It was also reported that was installed a gene that contributes to the appearance of dependence on cocaine.
