What is the Origin of Biological Aging Vector?

This term is rooted in the field of gerontology and epigenetics, specifically drawing upon the development of validated epigenetic clocks, such as the Horvath and Hannum clocks, which quantify biological age based on DNA methylation patterns. The addition of 'Vector' emphasizes the directional and rate-of-change component, moving beyond a static age assessment to a dynamic, predictive model. It serves as a clinical endpoint for anti-aging protocols.

What is the Mechanism of Biological Aging Vector?

Calculating the vector involves serial measurements of biological age biomarkers over time to determine the slope of the age-acceleration curve. A positive slope indicates a faster-than-average aging rate, while a negative slope suggests biological deceleration or reversal. Interventions in hormonal health, like optimizing growth hormone pulsatility or mitigating cellular senescence, are designed to flatten or reverse this vector, thereby extending healthspan.

Biological Aging Vector

Meaning

The Biological Aging Vector is a conceptual framework and quantitative metric that describes the direction and velocity of an individual’s biological age progression relative to their chronological age. It synthesizes data from multiple epigenetic, proteomic, and metabolic clocks to define the overall trajectory of systemic decline or, ideally, rejuvenation. Understanding this vector is central to developing targeted longevity interventions.
