AI finds shared metabolic signature of five lifespan-extending treatments in mice
Dr_Singularity · x · 2026-11-14
University of Michigan researchers report in Frontiers in Aging that five validated longevity interventions — rapamycin, acarbose, canagliflozin, 17α-estradiol, and caloric restriction — all raised levels of the natural antioxidant ergothioneine in the brains and blood of mice.
- Multi-tissue metabolomic analysis (7 tissues) of male UM-HET3 mice aged 4–12 months, using a feature-stabilized XGBoost pipeline: treated mice were distinguished from controls in 33 of 35 tests.
- The interventions also converge on lipid remodeling pathways.
- Implication: a shared biomarker could let researchers screen promising anti-aging therapies far faster, avoiding years-long lifespan studies.
