Metagenomic insights into urolithin formation from rambutan rind extract by rat faecal-derived microbiome

Applied Microbiology and Biotechnology
Ellagitannins and ellagic acid are microbially converted into urolithins, metabolites associated with antioxidant, anti-inflammatory, and mitochondrial-related activities.

Gut Metabolite Urolithin A Inhibits Osteoclastogenesis and Senile Osteoporosis by Enhancing the Autophagy Capacity of Bone Marrow Macrophages

Frontiers in Pharmacology, 2022
Graphical AbstractUro-A, which is a metabolite of intestinal flora and mainly produced from pomegranates and some nuts, suppresses osteoclast formation and bone resorption by activating autophagy.

Vaccarin Improves Myocardial Ischemia–Reperfusion Injury by Attenuating Oxidative Stress and Ferroptosis Through Reducing NOX4‐Modulated JAK2/STAT3 Pathway Activation

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Vaccarin is a naturally occurring flavonoid glycoside with cardioprotective properties; however, its involvement in myocardial ischemia–reperfusion (MI/R) injury remains poorly defined. We herein investigated whether vaccarin protects cardiomyocytes from MI/R‐induced dysfunction in vivo and in vitro and examined the associated molecular ...

In vivo administration of gut bacterial consortia replicates urolithin metabotypes A and B in a non-urolithin-producing rat model

Food & Function, 2023
The two bacterial consortia colonized the intestine of rats and converted UM-0 (non-urolithin-producing) animals into urolithin-producing animals mimicking the UM-A and UM-B metabotypes.

Therapeutic potential of natural products in cancer immunotherapy: Advances and challenges

British Journal of Pharmacology, EarlyView.
This review systematically outlines the mechanisms underlying tumour immunotherapy resistance and elucidates the role of natural products in enhancing therapeutic efficacy as immunomodulatory adjuvants. Abstract Immunotherapy has emerged as a clinically pivotal approach in cancer treatment, but its application remains limited to a small subset of ...

Urolithin A Attenuates Hyperuricemic Nephropathy in Fructose-Fed Mice by Impairing STING-NLRP3 Axis-Mediated Inflammatory Response via Restoration of Parkin-Dependent Mitophagy

Frontiers in Pharmacology, 2022
Urolithin A (UroA) is one of the primary intestinal metabolites of ellagitannins, showing translational potential as a nutritional intervention in humans.

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 ...

Treating age‐related loss of muscle mass and function: Where should we be focusing?

The Journal of Physiology, EarlyView.
Abstract figure legend Perturbations contributing to the age‐related loss of muscle mass and strength. A, in the spinal cord, self‐reinforcing cycles of oxidative stress, mitochondrial dysfunction and inflammation mediated by cells, including microglia, contribute to motor neuron degeneration.

In vitro conversion of ellagic acid to urolithin A by different gut microbiota of urolithin metabotype A

Applied Microbiology and Biotechnology
Abstract The metabolite urolithin A, a metabolite of the dietary polyphenol ellagic acid (EA), has significant health benefits for humans. However, studies on the gut microbiota involved in ellagic acid metabolism are limited.

Downstream Pathways of Dystrophin Deficiency in Duchenne Muscular Dystrophy: Implications for Muscle Degeneration and Regeneration

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 4, August 2026.
ABSTRACT Background Duchenne muscular dystrophy (DMD) is the most common and severe form of muscular dystrophy, primarily affecting skeletal muscle and leading to premature death. Although the loss of dystrophin has long been recognised as the primary cause of the disease, no definitive cure is currently available. As a consequence, therapeutic efforts
