Association Characteristics and Potential Mechanisms of Aging, Gut Microbiota, and Hearing Loss

Integrative Zoology, EarlyView.
The study found that aging leads to unchanged gut microbiota alpha diversity but an increase in Bacteroidetes and a decrease in Firmicutes at the phylum level, with specific genera, species, and functional pathways co‐associated with aging and hearing loss. Through constructing a microbe‐metabolite network, it revealed the mechanism by which protective

Alamandine/MrgD pathway modulates gut–bone marrow axis in ageing

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Ageing is associated with colon epithelial barrier disruption and up‐regulation of myelopoiesis in the bone marrow (BM). Alamandine (Ala) and MrgD are novel members of the renin angiotensin system (RAS). This study tested the hypothesis that Ala restores the colon epithelial barrier integrity in ageing via modulating gut–

Adaptation to extreme environments: A review of Antarctic fish physiology

Journal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

Trimethylamine N-Oxide (TMAO) and cancer risk: Insights into a possible link

Biomedicine & Pharmacotherapy
The gut microbiota play a crucial role in cancer pathogenesis, partly through metabolites derived from dietary components or host compounds. Among these, trimethylamine N-oxide (TMAO), a secondary gut microbiota-derived metabolite has gained attention for its potential link to cancer. TMAO is formed when gut microbes convert dietary choline, carnitine,

Development and Application of a UPLC–MRM–MS Method for Quantifying Trimethylamine, Trimethylamine-N-Oxide, and Related Metabolites in Individuals with and Without Metabolic Syndrome

Separations
Trimethylamine-N-oxide (TMAO) is associated with various chronic diseases. TMAO is a downstream oxidative metabolite of trimethylamine (TMA) that is generated by the gut microbiota from dietary choline, carnitine, and betaine.

Four Haylages, One Metabonome: Defining Diet Driven Metabolic Shifts in Ponies

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Haylage is widely fed to all categories of stabled horses across Europe and New Zealand. Haylage can vary from high energy nutrient dense forage to low energy highly fibrous fodder, yet little is known about the impact different haylages have on metabolism in horses.

Intestinal Microbiota Composition Modulates Choline Bioavailability from Diet and Accumulation of the Proatherogenic Metabolite Trimethylamine-N-Oxide

mBio, 2015
Choline is a water-soluble nutrient essential for human life. Gut microbial metabolism of choline results in the production of trimethylamine (TMA), which upon absorption by the host is converted in the liver to trimethylamine-N-oxide (TMAO).

Microbiome and Metabolomics in Obesity: Advances in Understanding and Interventions Across the Lifespan

Obesity Reviews, EarlyView.
ABSTRACT Obesity arises from intertwined and reciprocal diet‐microbiome‐host pathways that reshape energy balance, insulin sensitivity, and inflammation. This review synthesizes mechanistic links between microbial functions and metabolic control, charts lifestyle‐related lifecourse dynamics from birth to older age, examines how GLP‐1‐based therapies ...

Metabolic pattern across energy imbalance: An exploratory metabolomics study of female body weight extremes including anorexia nervosa and athletes

Experimental Physiology, EarlyView.
Abstract In anorexia nervosa (AN), prolonged metabolic adaptation to severe energy deficiency can impair treatment efficacy. Similarly, low energy availability poses a recognized risk to athletes, potentially compromising health and performance. This cross‐sectional study aimed to characterize the plasma metabolic pattern of females with varying ...

Effects of SGLT‐2 Inhibitors on Plasma Concentrations and Renal Clearance of the Risk Marker Trimethylamine‐N‐Oxide in Patients With Type‐2 Diabetes

Endocrinology, Diabetes &Metabolism, Volume 9, Issue 6, November 2026.
Treatment with empagliflozin or dapagliflozin was associated with a modest increase in plasma concentration of TMAO in Type 2 diabetes patients. These findings suggest a possible class effect of SGLT‐2 inhibitors. Whether this effect impacts the overall clinical benefits of SGLT‐2 inhibitors needs to be subject to further investigation.
