The work is based on a relatively new concept in aging research: that chemical modifications to a person’s DNA over a lifetime create what is known as an epigenetic clock. Scientists have built a case that one such modification, the addition of methyl groups to specific DNA sequences, tracks human biological age—that is, the toll that disease, poor lifestyle, and genetics take on our bodies. As a result, some groups have converted a person’s DNA methylation status to an age estimate—or even a prediction of life expectancy (worrying ethicists, who say the data could be misused by forensic investigators and insurance companies).
Other species also undergo DNA methylation as they age. Mice, chimpanzees, wolves, and dogs, for example, all seem to have epigenetic clocks. To find out how those clocks differ from the human version, geneticist Trey Ideker of the University of California, San Diego, and colleagues started with dogs. Even though man’s best friends diverged from humans early in mammalian evolution, they’re a good group for comparison because they live in the same environments and many receive similar healthcare and hospital treatments.
