Can old dogs teach us new tricks about human aging? Because dogs’ immune systems are “second only in sophistication” to humans', studying their genome sequence over time may provide valuable insights, hereandnow reports.
Researchers are undertaking what they say is the largest open study on aging ever on one beloved subject — dogs.is funded by a $15 million grant from the National Council on Aging. Scientists' goal is to discover new aspects of human aging by studying dogs, which share many diseases and genetic markers with humans.
Because dogs’ immune systems are “second only in sophistication” in humans, studying their genome sequence over time may provide valuable insights into human aging. The Dog Aging Project will also research environmental variations, he says, including air quality, water quality, pesticide use, and even whether the dog lives in a hardwood or carpeted home.
Promislow says about 4% or 5% of the participating dogs will be enrolled in a clinical study to test rapamycin — a drug used to improve a “healthy lifespan.” When tested in low doses on worms, flies and mice, the drug can help them live healthier and for longer, he says.
