Urolithin A alleviates neuropathic pain and activates mitophagy

Molecular Pain, 2023
Neuropathic pain (NP) occurs frequently in the general population and has a negative impact on the quality of life. There is no effective therapy available yet owing to the complex pathophysiology of NP. In our previous study, we found that urolithin A (UA), a naturally occurring microflora-derived metabolite, could relieve NP in mice by inhibiting the

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.

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 ...

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 ...

In Silico and In Vitro Study of Antioxidant Potential of Urolithins

Antioxidants, 2023
In this work, quantum chemical calculations based on density functional theory (DFT) were performed to predict the antioxidant potential of four bioactive gut microbiota metabolites of the natural polyphenols ellagitannins (ETs) and ellagic acid (EA), also known as urolithins (UROs). In order to evaluate their ability to counter the effect of oxidative

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 ...

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.
