Semaglutide extends lifespan and curbs aging indicators in mice, study finds
ScienceDaily reports that semaglutide lengthened median lifespan and improved physical markers in older mice.
The short version
- Researchers observed that semaglutide reduced signs of aging and increased median lifespan by nearly 100 days in older healthy mice.[ScienceDaily]
- Treated animals exhibited improved muscle and cognitive performance alongside reduced inflammation.[ScienceDaily]
- Scientists noted the effects may operate through mechanisms separate from calorie restriction.[ScienceDaily]
- Researchers emphasized that the results do not prove semaglutide extends human lifespan and require clinical verification.[ScienceDaily]
Key facts
- Administering semaglutide to older healthy mice extended their median lifespan by nearly 100 days compared to untreated controls.[ScienceDaily]
- Treated mice demonstrated reduced inflammation as well as improved muscle and cognitive function.[ScienceDaily]
- Researcher Danica Chen noted differences between semaglutide and dietary restriction that suggest GLP-1 drugs might function via a distinct biological mechanism.[ScienceDaily]
- Rafael de Cabo suggested that slowing the aging process could explain why GLP-1 treatments produce a broad variety of clinical benefits.[ScienceDaily]
What remains uncertain
- It remains unknown whether semaglutide can extend lifespan or slow aging in humans, requiring further clinical studies.[ScienceDaily]
