Organ-specific aging research: a computational preprint testing whether blood biomarkers and face photos can proxy organ-by-organ biological age; a concise preview of the study type and reader value.
Key Takeaways
- Researchers trained organ-specific aging models on paired blood and tissue RNA from about 1,000 GTEx donors and tested them on held-out samples.
- Face-photo and blood-methylation proxies reproduced blood-based organ scores for 38–39 organs at correlations above 0.2 in external cohorts.
- Face-based mortality prediction reached AUC 0.74 for 20-year survival and methylation predicted 10-year cardiovascular survival with AUC 0.76.
