EngagementHigh engagement
Many discussions delve into methodological aspects, implications for aging, and future potentials—some referencing specific experiments and biological concepts, demonstrating meaningful involvement.
ImpactModerate impact
While users recognize potential for health and longevity, some comments remain cautious, suggesting the findings could influence future research and treatment approaches but are not yet definitive.
Abstract in brief
Rapamycin, which inhibits the mTOR signaling pathway, was shown to extend the lifespan of genetically diverse mice when fed starting at 600 days old, increasing median and maximum lifespan.
The study found that rapamycin's lifespan-extending effects were observed in both male and female mice across three different test sites, without altering their disease patterns, suggesting it may delay death from age-related diseases like cancer.
These findings are significant because they are the first to demonstrate that mTOR signaling influences mammalian lifespan and that pharmacological interventions like rapamycin can extend lifespan in both genders, opening potential avenues for treating age-related diseases.]

Rapamycin's life-extending effect is not very good. In 20-month-old mice (equivalent to 60-year-old humans), the median lifespan of males increased by only 9% after administration of rapamycin (doi: 10.1038/nature08221). Because rapamycin is an immunosuppressant (a Group 1 https://t.co/NyJ8ZBAnjD

@JoinLifespan Best answer to 'it's hype' is rigor. NIA's Interventions Testing Program runs compounds at 3 sites in genetically diverse mice, and rapamycin started at 600 days old (late in life) still extended lifespan in both sexes. That's the bar for human claims too. https://t.co/AF1ZcLAWkW

@agingroy Standard chow, eh?
The problem with standards is that there are so many of them. Let's make this concrete.
The most important experiment establishing rapamycin's life-extending properties in mammals was published in Nature in July 2009 by the National Institute on Aging

@grok @LMV112233 @greek_scientist @rand_longevity @MarcosArrut @davidasinclair Rapamycin cannot be used as an anti-aging drug.
Inhibiting cell division has achieved some life-extending effects in mammals, but with significant side effects.
For example, rapamycin has a life-extending effect, but it has significant side effects. This is because many cells

@CollinEwald asks 'can longevity interventions work late in life?'. Yes, daf2 degradation at 25% survival point still manages to almost double baseline lifespan (see also https://t.co/SBWLG5bInU). How does this work, slowing or reversing #Aging? 1/n
