Abstract

Essence

exBAClock centralizes published biological aging clocks and their reported links to disease, mortality, lifestyle, and clinical trials.

Evidence

This web resource integrates more than 100 clock formulas from 95 publications plus association data from about 270 additional articles.

Caveat

It is a literature database, not a new clock, universal biological-age formula, or independent validation study.

Simplified

Biological age, as opposed to chronological age, quantifies the body's functional state and rate of aging. Despite the absence of a universal formula for its determination, panels of biomarkers that change consistently with age are used to construct predictive aging clocks. These models enable the identification of accelerated aging and are valuable as surrogate endpoints in clinical trials. The proliferation of published aging clocks has created a challenge: data is fragmented across numerous publications, making manual extraction and analysis highly labor-intensive. To consolidate this information, we present exBAClock, a comprehensive, web-based database for exploring aging clocks (https://akob.shinyapps.io/exbaclock/). exBAClock integrates multiple functional modules, featuring structured tables on clocks (over 100 formulas from 95 publications), their predictors, and their associations with diseases, mortality, lifestyle, and clinical trials (about 270 more articles).
