DNA methylation patterns change dynamically throughout the lifespan, serving as a molecular marker for monitoring aging and predicting life expectancy, although the underlying causal mechanisms remain largely undiscovered.
Your DNA methylation patterns are not fixed; they change with age and environment. While we cannot yet reverse aging via methylation, tracking these changes (biological age) may offer insights into health status. Lifestyle factors like physical activity and diet influence these patterns, suggesting that maintaining a healthy lifestyle may positively impact your epigenetic profile.
DNA methylation is currently the most promising molecular marker for monitoring aging and predicting life expectancy. However, the mechanisms underlying age-related DNA methylation changes remain mostly undiscovered.
Why this rating
Based on a comprehensive review of multiple studies, longitudinal data, and twin studies, though it is a review paper rather than primary experimental data.
