Dog aging and DNA changes

Caption

Drawing on data from 864 dogs enrolled in the Dog Aging Project, a team of scientists, including Noah Snyder-Mackler, mapped genome-wide patterns of DNA methylation. Their findings reveal that aging is associated with the widespread loss of these methylation regulatory marks over time, particularly in regions of the genome known as “jumping genes” or transposable elements.
