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

Aging &amp; Longevity

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. 


Model: Skin, arterial, and lens tissue from donors between the ages of 20 and 25 and also 75 
Dosage: 5 µM solution of CMLase, incubated overnight

Bioengineered Enzyme Shows Ability to Reverse Molecular Aging in Human Tissue

An engineered enzyme reverses age-related protein damage that researchers have long thought irreversible in human eye, skin, and artery tissues.

A bioengineered enzyme reverses age-related protein damage, long thought of as irreversible damage, in human lens, skin, and artery tissues.

Basic Research

Model: Male Wistar rats 
Dosage: 1.5 g/kg/day of orally administered glycine for 5 months

Glycine, an amino acid shown to extend the lifespan of mice, moderately extends the lifespan of flies and counters brain and muscle degeneration in aged rats. 

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.
