A research article investigating how targeting a muscle circadian clock protein may explain why exercise helps restore daily rhythms and heart health in aging flies.
Key Takeaways
- Muscle-specific upregulation of the circadian protein Timeless improved age-associated circadian rhythm parameters in Drosophila.
- Exercise-induced Timeless increases were linked to measurable improvements in age-related cardiac dysfunction in the fly model.
- Genetic manipulation showed the muscle Timeless effect was necessary for the exercise benefit on both rhythms and cardiac performance.
