Aging Clocks Applied to Human Trial Data Support AI-Designed Drug Lowering Age

Six proteomics-based aging clocks (age assessments from large-scale analyses of proteins) agreed that patients treated with the AI-designed drug rentosertib appeared younger.

The AI-designed drug rentosertib was shown to lower biological age across six aging clocks in patients with idiopathic pulmonary fibrosis.

Model: Chronically stressed mice 
Dosage: 9 mg/kg/day of L-serine, or 5 mg/kg/day of dasatinib combined with 50 mg/kg/day of quercetin

Supplementing chronically stressed mice with L-serine, an amino acid, counters signs of anxiety and diabetes while diverting age-promoting senescent cells within the brain’s fear center.

Model: 20-month-old female C57BL/J mice 
Dosage: 10 nmol/kg/day of semaglutide

Semaglutide extends mouse lifespan and targets signs of aging, such as diminished NAD+, while mimicking the anti-aging effects of caloric restriction (consuming fewer calories). 


The study was led by Dr. Danica Chen (image: berkeley.edu). 

Model: 6-week-old ICR mice
Dosage: 250 mg/kg per day or 500 mg/kg per day of glucosamine and 100 mg/kg per day or 200 mg/kg per day of aspirin for either eight (acute alcohol exposure model) or 40 days (chronic alcohol exposure model)

New Study Supports Repurposing Glucosamine Against Liver Aging

A sugar-like compound found in cartilage called glucosamine reduces dysfunctional cells (senescent cells) in the liver and attenuates liver damage from alcohol consumption in mice.

Glucosamine alleviates liver damage from alcohol consumption in mice, supporting its potential for use against alcoholic liver disease.
