Trimethylamine-N-oxide and cerebral stroke risk: A review

Neurobiology of Disease
Trimethylamine-N-oxide (TMAO) is a gut microbiota-derived metabolite produced by the action of gut microbiota and the hepatic enzyme Flavin Mono‑oxygenase 3 (FMO3).

Regulation of blood–brain barrier integrity by microbiome-associated methylamines and cognition by trimethylamine N-oxide

Microbiome, 2021
Background Communication between the gut microbiota and the brain is primarily mediated via soluble microbe-derived metabolites, but the details of this pathway remain poorly defined. Methylamines produced by microbial metabolism of dietary choline and l-

The microbial metabolite trimethylamine N-oxide promotes antitumor immunity in triple-negative breast cancer

Cell Metabolism, 2022
Immunotherapy has achieved limited success in patients with triple-negative breast cancer (TNBC), an aggressive disease with a poor prognosis. Commensal microbiota have been proven to colonize the mammary gland, but whether and how they modulate the ...

The gut microbial metabolite trimethylamine N-oxide and cardiovascular diseases

Frontiers in Endocrinology, 2023
Morbidity and mortality of cardiovascular diseases (CVDs) are exceedingly high worldwide. Researchers have found that the occurrence and development of CVDs are closely related to intestinal microecology.

Association between egg-derived phosphatidylcholine intake and trimethylamine N-oxide in healthy middle-aged and older adults [PDF]

Lipids in Health and Disease
Background Egg-derived phosphatidylcholine may support the maintenance of cognitive function. However, its metabolite trimethylamine N-oxide is considered a potential cardiovascular risk factor.

Longitudinal metabolomics reveals dynamic associations of trimethylamine N-oxide and precursors with the progression of gestational diabetes [PDF]

BMC Pregnancy and Childbirth
Background Trimethylamine N-oxide (TMAO) and its precursor metabolites are strongly linked to glucose and lipid metabolic disorders, yet their dynamic roles and overall effects in gestational diabetes mellitus (GDM) have not been clarified.

Trimethylamine N-Oxide Binds and Activates PERK to Promote Metabolic Dysfunction

Cell Metabolism, 2019
The gut-microbe-derived metabolite trimethylamine N-oxide (TMAO) is increased by insulin resistance and associated with several sequelae of metabolic syndrome in humans, including cardiovascular, renal, and neurodegenerative disease.

Trimethylamine N-oxide impairs β-cell function and glucose tolerance

Nature Communications
β-Cell dysfunction and β-cell loss are hallmarks of type 2 diabetes (T2D). Here, we found that trimethylamine N-oxide (TMAO) at a similar concentration to that found in diabetes could directly decrease glucose-stimulated insulin secretion (GSIS) in MIN6 ...

Porphyromonas gingivalis drives trimethylamine-N-oxide accumulation via modulation of gut microbial trimethylamine lyase in mice [PDF]

Frontiers in Microbiology
IntroductionTrimethylamine N-oxide (TMAO), a gut microbiota-derived metabolite, is linked to cardiovascular, neurodegenerative, and metabolic diseases. Emerging evidence indicates a bidirectional interaction between the periodontal pathogen Porphyromonas

Gut microbiota dependent trimethylamine N-oxide aggravates angiotensin II–induced hypertension

Redox Biology, 2021
Gut microbiota produce Trimethylamine N-oxide (TMAO) by metabolizing dietary phosphatidylcholine, choline, l-carnitine and betaine. TMAO is implicated in the pathogenesis of chronic kidney disease (CKD), diabetes, obesity and atherosclerosis.
