Scientists have identified a new family of metabolites that connect two crucial cellular processes, potentially revolutionizing our understanding of aging and disease treatment.
Why it matters: This breakthrough links spermidine (found in all living cells) with sirtuins (key aging-related enzymes) for the first time. The discovery could lead to new therapeutic approaches for age-related diseases and longevity enhancement.
- Aging research has long focused on sirtuins, but their connection to other cellular processes remained unclear.
Key finding: Researchers at the Boyce Thompson Institute discovered acylspermidines, a novel family of metabolites that influence lifespan in simple organisms and cell growth in mammals, including humans.
“We were excited to uncover this unexpected branch of cellular metabolism related to sirtuins.”

The process:
- Used comparative metabolomics to screen for sirtuin-dependent changes
- Tested findings across species, from C. elegans to mammals
- Demonstrated direct impact on lifespan and cell proliferation
Keep in mind: While promising, the research is still in early stages and requires further investigation into mechanisms and pharmacological applications.
Real-world impact: This discovery could lead to:
- New drug development targeting age-related diseases
- Better understanding of cellular aging processes
- Improved therapeutic interventions for longevity
TL;DR
- Scientists discovered new metabolites linking spermidine and sirtuins, two crucial cellular components.
- The findings apply across species, from simple organisms to humans.
- This breakthrough could revolutionize how we treat age-related diseases and approach longevity.
