Aging and Longevity

Epigenetic Aging & Longevity Research

Biological age, measured through DNA methylation patterns, often diverges from chronological age. This “epigenetic age acceleration” is associated with disease risk, mortality, and healthspan. Methylation-based clocks enable quantitative assessment of aging at the molecular level.

Epigenetic Aging Clocks

Multiple validated clocks exist, each measuring different aspects of aging:

  • Horvath Clock: 353 CpG sites (Multi-tissue). General age prediction; tissue-agnostic aging measure. (2013)
  • Hannum Clock: 71 CpG sites (Blood-based). Faster analysis; hematopoietic aging focus. (2013)
  • GrimAge: 1,030+ CpG sites (Blood-based). Mortality predictor; disease outcome association. (2018)

Age Acceleration Concept

Age acceleration = DNAm Age – Chronological Age

Positive acceleration indicates premature aging and is associated with increased mortality risk, higher incidence of age-related diseases, reduced cognitive function and healthspan, and predictive value for disease onset before symptoms appear.

Applications in Longevity Research

  • Intervention efficacy assessment (exercise, diet, pharmaceuticals)
  • Personalized aging trajectory monitoring
  • Identification of individuals at high risk for age-related disease
  • Drug development and clinical trial biomarker validation
  • Geroscience research on aging biology
