Key points from article :
Scientists significantly extended lifespan in male mice by inhibiting the enzyme CD38.
Researchers inhibited CD38 with the molecule 78c and followed one-year-old naturally aging mice until death.
78c was fed to young mice, which significantly boosted NAD levels.
Treatment resulted in a 9% extension in maximum lifespan.
In males, a 14% increase in maximum lifespan and a 17% increase in median lifespan were recorded.
No statistically significant survival benefit in females.
Hypothesized that CD38 deficiency causes non-fatal deleterious conditions in female mice.
At the age of two years (~ 60 human years), and 50 weeks after the treatment, rate of age-related fitness loss was much slower.
78c improves lifespan not via any evident anti-cancer effect.
Combination of 78c and an anti-cancer drug can lead to an even greater increase in lifespan.
An alternative way to boost NAD levels in aging organisms.
