Model: 6- to 8-week-old male C57BL/6J mice
Dosage: 0.5 mg/kg of isolated mitochondria injected every two days for six injections in the tail vein

Mitochondrial Transplantation Rejuvenates Aging Hearts, Study Finds

Transplantation of the cell’s powerhouses (mitochondria) improves heart function by restoring mitophagy (the cellular process that clears damaged mitochondria) in a mouse model of cardiac aging.

Mitochondrial transplantation improves heart function by restoring the cellular process that clears damaged mitochondria in a mouse model of cardiac aging.

Cardiovascular

NAD+ (nicotinamide adenine dinucleotide) levels were lower among older adults with frailty—an age-related condition associated with increased vulnerability to disability, disease, and death.

Skin &amp; Muscle

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). 

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.

Scientists find that meloxicam preserves muscle mass and strength in aged mice while sustaining mitochondrial function and activating multiple molecules associated with longevity.
