Paper

Abstract

DNA methylation (DNAm), an epigenetic mechanism that regulates gene activity in response to genetic and environmental influences, changes as we age. DNAm at specific sites on the genome can be used to calculate 'epigenetic clocks', which are powerful biomarkers of age, as well as of ageing. However, little is known about how these clock sites 'behave' during development and what factors influence their variability in early life. This knowledge could be used to optimise healthy ageing well before the onset of age-related conditions.

Research summary

The paper investigates the dynamics of DNA methylation at epigenetic clock sites during development, which is pertinent to understanding the biological mechanisms of aging. By exploring how these sites behave and their variability in early life, the research could contribute to optimizing healthy aging and potentially inform strategies for lifespan extension. However, while the findings may provide solid insights into the epigenetic aspects of aging, they do not present a major breakthrough or transformative implications for the field, thus warranting a moderate impact score.
