flag Dog blood tests reveal aging biomarkers linked to kidney function, with potential for human anti-aging research.

flag Blood tests in dogs may help reveal key insights into human aging, according to a study involving nearly 800 dogs from the Dog Aging Project. flag Researchers found that over 40% of small molecules in dog blood, including post-translationally modified amino acids linked to protein breakdown, change with age and may reflect declining kidney function. flag These metabolites, influenced by gut bacteria and genetics, could serve as biomarkers for aging pace and health decline. flag The findings, based on data from dogs of various breeds and sizes, suggest potential applications in tracking biological aging and testing anti-aging treatments, with possible benefits for both species. flag The study, funded by the NIH and other groups, is ongoing, with plans to monitor changes over time and explore links to muscle loss and longevity.
