Urolithin A Is a Dietary Microbiota-Derived Human Aryl Hydrocarbon Receptor Antagonist

Metabolites, 2018
Urolithins (e.g., UroA and B) are gut microbiota-derived metabolites of the natural polyphenol ellagic acid. Urolithins are associated with various health benefits, including attenuation of inflammatory signaling, anti-cancer effects and repression of ...

Supplementation of Weizmannia coagulans BC2000 and Ellagic Acid Inhibits High-Fat-Induced Hypercholesterolemia by Promoting Liver Primary Bile Acid Biosynthesis and Intestinal Cholesterol Excretion in Mice

Microorganisms, 2023
The probiotic Weizmannia coagulans (W. coagulans) BC2000 can increase the abundance of intestinal transforming ellagic acid (EA) bacteria and inhibit metabolic disorders caused by hyperlipidemia by activating liver autophagy.

Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Urolithin A improves Alzheimer's disease cognition and restores mitophagy and lysosomal functions

bioRxiv
Background Compromised autophagy, including impaired mitophagy and lysosomal function, is thought to play a pivotal role in Alzheimer’s disease (AD). Urolithin A (UA) is a gut microbial metabolite of ellagic acid that stimulates mitophagy. The effects of

The effects of a (poly)phenol‐rich food intervention on markers of exercise‐induced inflammation and oxidative stress: A randomised controlled trial

Experimental Physiology, EarlyView.
Abstract This study examined whether consuming a (poly)phenol‐rich food before strenuous muscle‐damaging exercise can modify post‐exercise markers of inflammation and oxidative stress. Using a double‐blinded, randomised, placebo‐controlled, between‐subjects design, 26 recreationally active males (n = 15) and females (n = 11) consumed higher‐(poly ...

Microbiome‐Derived Tryptophan Metabolites Regulate AhR Signaling to Restore Epithelial Barrier Integrity in Inflammatory Bowel Disease

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
The graphical abstract illustrates how microbiome‐derived indoles activate the aryl hydrocarbon receptor to restore the intestinal barrier. The picture contrasts the “leaky gut” state with the restored homeostasis achieved through AMPK, Nrf2, and IL‐22 signaling.

Organoids in Precision Radiotherapy: Methodological Foundations, Tumor‐Specific Evidence, and Translational Roadmaps

Cancer Medicine, Volume 15, Issue 9, September 2026.
ABSTRACT Background Radiotherapy remains a cornerstone of cancer treatment, while its efficacy is often limited by tumor radioresistance and the risk of normal tissue toxicity. Conventional preclinical models, including two‐dimensional (2D) cell cultures and murine xenografts, exhibit significant limitations in recapitulating human tumor ...
