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.

Aging &amp; Longevity

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

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.

Immunity

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. 

Longevity Medicine’s Peptides Craze: Evidence, Delivery Challenges, and Expert Opinions

Advocates say peptides offer significant benefits against aging, while researchers warn that these claims outpace the evidence.

Proponents say peptides offer significant effects against aging, while skeptical scientists say these claims outpace the evidence.

How to Slow Aging: 7 Tips from a Danish Aging Expert

Danish aging expert Morten Scheibye-Knudsen shares seven ways to slow aging, including taking NR (nicotinamide riboside) and the diabetes medication metformin.

Danish aging expert Morten Scheibye-Knudsen does things like taking NR and metformin to slow his biological aging

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. 

Model: C57BL/6J mice 
Dosage: Eating only within an 8-hour window and fasting for 16 hours (~20% caloric deficit may be required)

Restricting food intake for 16 hours a day improves the health of female mice and moderately prolongs the life of male mice.
