Some parts of your body age faster than others, Israeli study finds

A new study from the Hebrew University of Jerusalem reveals that aging is not uniform across the body: individual cells age at different rates, and a molecular 'aging signature' based on DNA methylation has been identified. Published in Nature Communications, the findings could pave the way for new cancer treatments and early disease detection. The researchers hope that understanding why some cells age faster will help develop drugs to slow the aging process itself.

A new study from the Hebrew University of Jerusalem challenges the assumption that all body parts age at the same rate. Led by Prof. Howard Cedar, the researchers discovered that individual cells age at different speeds, and they identified a molecular 'aging signature' based on DNA methylation. This finding could lead to new cancer treatments and earlier detection of diseases. The study, published in Nature Communications, suggests that aging is an active biological program rather than random wear and tear. The team hopes that understanding why some cells age faster could help develop drugs to slow aging itself. The research also builds on Cedar's earlier work on DNA methylation, which underpins a new early-detection kit for over 50 types of cancer.
