The Metabolite Urolithin-A Ameliorates Oxidative Stress in Neuro-2a Cells, Becoming a Potential Neuroprotective Agent

Antioxidants, 2020
Urolithin A is a metabolite generated from ellagic acid and ellagitannins by the intestinal microbiota after consumption of fruits such as pomegranates or strawberries.

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.

Aging of Skeletal Muscle: From Molecular Mechanisms to Therapeutic Interventions

MedComm, Volume 7, Issue 10, October 2026.
Skeletal muscle aging is driven by coordinated local breakdown across myofibers, stem and stromal cells, immune and vascular compartments, and neuromuscular control. These mechanisms promote mitochondrial dysfunction, inflammation, senescence, impaired regeneration, fibrosis, myosteatosis, denervation, and functional decline.

Polyphenol‐Rich Foods as a Healthy and Sustainable Strategy: Mental Health and Metabolomic Profiling

Molecular Nutrition &Food Research, Volume 70, Issue 19, 15 October 2026.
A 12‐week nutritional intervention with cocoa flavanols and red‐berry anthocyanins in older adults improved emotional well‐being and identified metabolomic signatures associated with the intervention through urinary metabolome profiling. ABSTRACT The so‑called demographic transition has increased the prevalence of chronic diseases in adults over 65 ...

Ellagic Acid Enhances RSL3‐Induced Ferroptosis by Inhibiting the Nrf2/HO‐1 Signaling Pathway in Pancreatic Ductal Adenocarcinoma

The FASEB Journal, Volume 40, Issue 18, 30 September 2026.
Ellagic acid potentiates RSL3‐induced ferroptosis in PANC‐1 by suppressing the Nrf2/HO‐1 antioxidant defense axis via p38 MAPK activation and Keap1 upregulation. In PDAC cells, constitutive Nrf2/HO‐1 signaling establishes a robust antioxidant shield (GPX4, HO‐1) that limits lipid ROS accumulation and confers ferroptosis resistance.

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 ...

Unlocking the Hepatoprotective Potential of Urolithin A in High‐Fat Diet‐Induced MASLD: Integrated Role of Oxidative Stress, Inflammation, FXR/PPAR‐α, and Fibrotic Pathway

Cell Biochemistry and Function, Volume 44, Issue 9, September 2026.
ABSTRACT “Metabolic dysfunction–associated steatotic liver disease” (MASLD) is marked by hepatic steatosis, oxidative stress, inflammation, and fibrosis. Urolithin A (Uro A), a metabolite of ellagitannins, exhibits anti‐inflammatory, antioxidant, and metabolic regulatory activities.

Mechanistic Insights Into the Association Between Gut Microbiota Diversity and Atherosclerosis, Acute Coronary Syndrome, and Peripheral Arterial Disease Progression

Clinical Cardiology, Volume 49, Issue 9, September 2026.
Proposed gut‐vascular framework linking microbial ecology to atherosclerotic disease. Diet and related exposures shape dysbiosis or microbial resilience; resulting changes in SCFAs, TMAO, bile acids, and LPS may modulate endothelial function, immune activation, and platelet activity, contributing to atherosclerosis, ACS, and PAD.

In vivo administration of urolithin A and B prevents the occurrence of cardiac dysfunction in streptozotocin-induced diabetic rats

Cardiovascular Diabetology, 2017
Background Emerging evidence suggests that specific (poly)phenols may constitute new preventative strategies to counteract cell oxidative stress and myocardial tissue inflammation, which have a key role in the patho-physiology of diabetic cardiomyopathy.
