Restoring circadian rhythms in the hypothalamic paraventricular nucleus reverses aging biomarkers and extends lifespan in male mice.

Age-related circadian disruptions accelerate physiological decline and shorten lifespan. Enhancing circadian amplitude has emerged as a promising strategy for ameliorating age-associated disorders. Here, we show that the circadian-phase-optimized administration of 3'-deoxyadenosine (3dA) strengthens circadian amplitude …
