Can Testing Drugs in Five Species Help Us Find Treatments for Healthy Aging?

A new study describes a large cross-species testing system—using species from yeast to mice—to identify promising lifespan-extending drug candidates more efficiently.

A new platform tests aging intervention drugs in five animal model species—yeast, worms, flies, fish, and mice.

Aging &amp; Longevity

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.

Finalist Teams Awarded $1 Million in XPrize Healthspan Contest to Transform Healthy Aging

The XPrize Healthspan—which will split $101 million among teams developing therapeutics to restore muscle, cognitive, and immune function in older adults—has named 10 teams receiving $1 million each.

The XPrize Healthspan competition has named its top 20 finalist groups that will submit their aging intervention therapies for human trial testing.

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.

The Overlooked Organ That Could Hold the Key to Fighting Aging

Scientists are researching ways to regrow the thymus, an immune organ that vanishes with age, to suppress the tolls of aging.

An organ involved in immunity, the thymus, vanishes as people get older, and scientists are researching ways to regrow it to fight aging.

Search Result: Metformin
