Unifying the Genetic Basis of Aging and Age-Related Diseases
A study has found that DNA methylation age, a measure of biological aging, is consistent across various mammalian tissues. The researchers analyzed DNA methylation patterns in 128 different tissues from 63 mammalian species and found that the methylation age was highly correlated across tissues. This suggests that DNA methylation age may serve as a universal biological clock across mammalian species, providing insights into the aging process and potential interventions.
