Caloric Restriction Slows DNA Mutations in Mice, NYU Study Finds
Event summary
- NYU Langone-led study shows 30% caloric restriction reduces DNA mutations in mice across multiple tissues.
- First genome-wide analysis reveals caloric restriction's impact on substitution, insertion, and deletion mutations.
- Liver cells show greater mutation reduction than kidney or brain cells under caloric restriction.
- Least active genomic regions benefit most from mutation reduction under caloric restriction.
The big picture
The study builds on established links between diet and lifespan, now demonstrating a direct connection between caloric restriction and genome-wide mutation rates. This research could open new avenues for understanding and potentially intervening in age-related diseases. NYU Langone's involvement underscores its position as a leader in translational medicine, particularly in genetics and aging research.
