Clinical Report: Dogs Share Our Mortality Markers
Overview
A longitudinal analysis from the Dog Aging Project reveals that 17% of plasma metabolites in dogs are associated with all-cause mortality. Notably, 64% of overlapping metabolites also show mortality associations in humans.
Background
Understanding mortality markers in companion animals like dogs can provide insights into aging and health in both species. The Dog Aging Project's findings may enhance our understanding of shared biological processes related to mortality.
Data Highlights
| Metabolite | Association with Mortality |
|---|---|
| Pseudouridine | Higher levels linked to mortality |
| N2-dimethylguanosine | Higher levels linked to mortality |
| Homocitrulline | Higher levels linked to mortality |
| Deoxycarnitine | Lower levels linked to mortality |
| Homoarginine | Lower levels linked to mortality |
Key Findings
- 17% of plasma metabolites in dogs are associated with all-cause mortality.
- 23 metabolites met the statistical significance threshold in the study.
- 104 dogs died during an average follow-up of 2.6 years.
- 64% of overlapping metabolites showed mortality associations in both dogs and humans.
- Several metabolites linked to renal function and aging biology were identified.
Clinical Implications
The identification of shared mortality markers between dogs and humans may facilitate further research into aging and health.
Conclusion
The findings from the Dog Aging Project highlight the associations between mortality markers in dogs and humans.
