Model: Eight-week-old C57BL/6J mice treated with 300 mg/kg/day of D-galactose by subcutaneous injections for eight weeks
Dosage: 100 mg/kg/day of NMN in drinking water for eight weeks and 5 × 10 5 hUC-MSCs suspended in 150 µL of PBS via tail vein injection on the first day of weeks five through seven

NMN Enhances Stem Cell Therapy’s Effects on Immune Aging in Latest Study

Combining NMN with umbilical cord–derived stem cells improved motor and cognitive function while reducing markers of immune aging in mice with chemically induced aging.

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.

(One of the leading authors on the Cell Press Blue article, Dr. Dudley Lamming | University of Wisconsin)

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

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.

(XPrize announced the finalists for its XPrize Healthspan competition | XPrize)

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 study was led by Dr. Irina Conboy (image: berkeley.edu).
