Scientists have revealed how to extend life to 120 years
Scientists have discovered a region of the human genome that influences life expectancy and health in old age.
It is found in mitochondrial DNA, which is responsible for energy production in cells.
Mitochondrial DNA differs from the main DNA, as it is transmitted to the child only from the mother. It has a ring structure and is similar to bacterial DNA, the RIA Novosti article emphasizes.
Scientists believe that mitochondrial DNA emerged as a result of an ancient symbiosis between single-celled organisms and animal cells.
As we age, critical errors accumulate in mitochondrial DNA, which affects muscle and nervous system diseases. Shortening this DNA makes it less effective, and eventually the cells begin to gradually die.
However, some people live to be 100–120 years old and remain healthy.
BFU scientists, as part of an international research team, propose using mitochondrial DNA from healthy donors as a “third parent.”
They believe that the new method will help avoid harmful mutations and ensure long life for future children. Such procedures are practiced in some countries.
