DNA Methylation Loss in 'Jumping Genes' Linked to Faster Aging in Large Dogs

A new study in Science reveals that large dogs age faster due to accelerated loss of DNA methylation, particularly in 'jumping genes' called LINE1s. This molecular instability correlates with higher mortality risks, offering a biological explanation for why big breeds die younger than small ones.

DNA Methylation Loss in Large Dogs Linked to Accelerated Aging

A new study published in Science suggests that large dogs age faster than small ones due to the rapid loss of DNA methylation marks that suppress 'jumping genes.' Analyzing nearly 900 dogs, researchers found that giant breeds lose these protective chemical tags 35% faster per year than small breeds, potentially leading to genomic instability and shorter lifespans.
