- Rochester Epidemiology Project — Mentioned as a resource linking medical records to biobank
- CALERIE trial — Mentioned as a clinical trial of caloric restriction
Concurring Sources
- Health ABC study — Validation of biomarkers in an independent cohort
Contribution & Novelties
The talk presents a pragmatic approach to developing a panel of senescence biomarkers and demonstrates their clinical utility across multiple cohorts and disease contexts. It highlights the potential for organ-specific biomarkers using proteomics, which could enable more targeted interventions. The emphasis on using biomarkers to predict response to senolytics is particularly novel.
