Scholars of Exeter and Essex universities found that epigenetic clock does not actually show the exact biological age of a person. Thus, the researchers disproved the popular myth about the benefits of exposure to methylated DNA, which supposedly can slow down aging. About it reported in a press release on ScienceX.

Experts assessed the epigenetic model hours is considered, it is possible to determine the biological age of a person. In the process of aging changes the proportion metilirovannah DNA, that is, the part of the genome that is attached to the methyl group. However, the data for these models were often received with the participation of young people, and the actual DNA methylation in the elderly were considered rare.

It turned out that epigenetic aging occurs at different speeds in different tissues. Epigenetic clock systematically underestimate the biological age of people was about 60 years. While scientists still do not know what is the cause of the delay of DNA methylation. The discrepancy between the epigenetic-aging and chronological age indicates the existence of a hypothetical Central mechanism, as DNA methylation is only a side process.
