By examining chemical tags on DNA that modulate our genes, scientists have discovered which genes are most affected by aging across more than a dozen human tissues.

The study was led by Dr. Nir Eynon from the Australian Regenerative Medicine Institute (image: vu.edu.au). 

Epigenetics

Model: Old (17- to 19-month-old) C57BL6 mice 
Dosage: 14 mg/mg/day of rapamycin in food for 5 months

A purported longevity drug, rapamycin, alters immune cells associated with cancer and reduces brain inflammation in mice. 

Immunity

Model: Female Balb/c mice exposed to ultraviolet radiation 
Dosage: 2%, 5%, 7.5%, or 12.5% of nicotinamide (weight/volume) applied topically, once daily, five times per week

The NAD+ (nicotinamide adenine dinucleotide) precursor nicotinamide prevents skin aging, in part by targeting age-promoting senescent cells in mice. 


New Framework Uncovers 21 Existing Drugs with Pro-Longevity Potential

A new gene network-based framework predicts the potential of existing drugs to confer pro-longevity effects.

A new gene network-based framework predicts already-approved repurposable drugs that may either confer pro-longevity benefits or age-accelerating effects.

Examining Evidence for the Cognition-Enhancing Potential of the Antioxidant Astaxanthin

The antioxidant astaxanthin significantly extends male mouse lifespan, and human research suggests it may help prevent age-related cognitive decline.

The potent antioxidant astaxanthin may have pro-longevity effects, and human trial data suggests it improves cognitive function in older adults.
