Protein Restriction and Longevity: Can Limiting Protein Intake Support Healthy Aging?

University of Wisconsin researchers examine how reducing dietary protein intake may reshape nutrient sensing, metabolism, mitochondrial function, and other pathways linked to healthier aging.

Researchers examine how restricting protein intake can improve metabolic health and influence aging-related pathways to extend healthspan and lifespan.

Aging &amp; Longevity

Model: Young acquired niacin dependency (ANDY) mice. 
Dosage: 30 mg/kg/day of niacin

Mice engineered to have low body-wide NAD+ levels exhibit a shortened lifespan and widespread physical decline, which is largely reversed with the NAD+ booster niacin. 

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.

Repurposing Erectile Dysfunction Pills for Longevity

Some people are taking erectile dysfunction medications like Cialis and Viagra for more than sex—rather, to help them live longer.

People have started repurposing erectile dysfunction medications, such as Cialis and Viagra, to help them live longer.

Model: Aged C57B/6 mice (between 18-25 months old) 
Dosage: 5 mg/kg/day of ABT-263 was fed to mice while 50 mg/kg/day of dichloroacetate and metformin were injected. For lifespan, they were administered for five consecutive days, followed by a two-day intermission, then an additional five consecutive days, followed by a 6-week intermission.

The combination of dichloroacetate, metformin, and ABT-263 eliminates cancer cells and age-promoting senescent cells while improving endurance and extending lifespan in mice.
