Activation of the miR-34a-Mediated SIRT1/mTOR Signaling Pathway by Urolithin A Attenuates D-Galactose-Induced Brain Aging in Mice.

ABSTRACT: Despite tremendous advances in modern medicine, effective prevention or therapeutic strategies for age-related neurodegenerative diseases such as Alzheimer's disease (AD) remain limited. Currently, accumulating evidence has demonstrated that microRNAs (miRNAs) are increasingly associated with age-related diseases and are emerging as promising therapeutic targets. Urolithin A, a metabolite compound resulting from the transformation of ellagitannins by gut bacteria, has been reported to have anti-oxidant, anti-inflammatory, and anti-apoptotic properties. The present study primarily focused on the ameliorative effect of urolithin A on aging mice and on the exploration of the potential mechanisms of such an ameliorative effect on cognitive impairment and brain aging. In this study, we first te
