Revealed the cause of aging of human cells



According to a study published in Nucleic Acids Research, human cells age as a result of damage to the genome, and these damage are irreversible. And this discovery goes against the theory of aging, which scientists adhered to earlier.

It was believed that telomeres (that is, the “caps” at the end of chromosomes; the main function of telomeres is to protect genetic information) with each cell division are destroyed, and when they become too short, they “tell” the cell to stop division. In this case, the researchers thought, DNA is not damaged. As a result, after the cessation of division, the cell begins to age.
