Epigenetic-based age acceleration in a representative sample of older Americans: Associations with aging-related morbidity and mortality
Biomarkers developed from DNA methylation (DNAm) data are of growing interest as
predictors of health outcomes and mortality in older populations. However, it is unknown …

Epigenetic clock: A promising biomarker and practical tool in aging
R Duan, Q Fu, Y Sun, Q Li - Ageing Research Reviews, 2022 - Elsevier
As a complicated process, aging is characterized by various changes at the cellular,
subcellular and nuclear levels, one of which is epigenetic aging. With increasing awareness …

[HTML][HTML] Effect of long-term caloric restriction on DNA methylation measures of biological aging in healthy adults from the CALERIE trial
The geroscience hypothesis proposes that therapy to slow or reverse molecular changes
that occur with aging can delay or prevent multiple chronic diseases and extend healthy …

Disparities in the pace of biological aging among midlife adults of the same chronological age have implications for future frailty risk and policy
Some humans age faster than others. Variation in biological aging can be measured in
midlife, but the implications of this variation are poorly understood. We tested associations …

Quantification of the pace of biological aging in humans through a blood test, the DunedinPoAm DNA methylation algorithm
Biological aging is the gradual, progressive decline in system integrity that occurs with
advancing chronological age, causing morbidity and disability. Measurements of the pace of …
