Biologists study gene regulation to explain why large dogs die younger

Original: 🐕 NEW: Biologists analyzed # DNA methylation across 864 # dogs in the Dog Aging Project, comparing how genes are regulat

Biologists with the Dog Aging Project analyzed DNA methylation across 864 dogs, examining how genes are regulated rather than the genes themselves. The work, reported by Popular Science, sheds light on why large dog breeds have shorter lifespans than smaller ones. The findings are drawing interest from scientists and pet owners interested in aging, genetics and longevity.

Why now: New research offers a biological explanation for a familiar puzzle: why bigger dogs live shorter lives.
