Dog Aging Project study links canine blood metabolites to human aging patterns
Researchers found that metabolic markers linked to lifespan in dogs closely mirror biological signals identified in human mortality studies.
The short version
- A study published in The Journals of Gerontology found that metabolic patterns in dog blood correlated with lifespan outcomes in ways similar to human mortality data.
- Researchers analyzed thousands of metabolites from pet dogs enrolled in the Dog Aging Project and compared them against five human mortality studies.
- Because dogs share human environments and have shorter lifespans, scientists plan to use these shared biological signals to accelerate aging research for both species.
Key facts
- Researchers with the Dog Aging Project published findings in The Journals of Gerontology showing that dogs and humans share similar metabolic patterns tied to mortality.[ScienceDaily]
- The study team analyzed blood samples and thousands of metabolites from participating pet dogs to identify biological markers associated with shorter or longer lifespans.[ScienceDaily]
- The dog metabolic patterns were evaluated against data from five published human mortality studies that used similar analytical methods.[ScienceDaily]
- The Dog Aging Project is a nationwide effort supported by the WoodNext Foundation that gathers survey data and annual physical samples from pet dogs.[ScienceDaily]
What remains uncertain
- Researchers noted that identified metabolic biomarkers correlate with lifespan outcomes but are not yet proven to directly cause earlier or later mortality.[ScienceDaily]
