Sex-specific differences in trimethylamine N-oxide (TMAO) concentrations before and after cardiac rehabilitation in acute myocardial infarction patients

EXCLI Journal : Experimental and Clinical Sciences, 2022
Trimethylamine N-oxide (TMAO) is a biomarker of cardiovascular risk and may enhance the progression of atherosclerosis. The aim of the study was to determine whether there are sex-specific differences in TMAO concentrations before and after cardiac ...

Trimethylamine-N-oxide (TMAO) increased aquaporin-2 expression in spontaneously hypertensive rats

Clinical and Experimental Hypertension, 2019
Recent evidence suggests that elevated plasma levels of Trimethylamine-N-oxide (TMAO) can prolong the duration of elevated blood pressure in rats. The purpose of this study was to investigate the plasma TMAO level in Spontaneously Hypertensive Rats (SHR)

Lactobacilli and Bifidobacterium as anti- atherosclerotic agents [PDF]

Iranian Journal of Basic Medical Sciences, 2022
Atherosclerosis is the thickening or hardening of the arteries which is caused by a buildup of atheromatous plaque in the inner lining of an artery. Hypercholesterolemia, inflammation, oxidative stress, and trimethylamine N-oxide (TMAO) are important ...

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.

Hawthorn fruit extract reduced trimethylamine-N-oxide (TMAO)-exacerbated atherogenesis in mice via anti-inflammation and anti-oxidation

Nutrition & Metabolism, 2021
Background Trimethylamine-N-oxide (TMAO) is an independent risk factor for atherosclerosis. Consumption of hawthorn fruit is believed to be cardio-protective, yet whether it is able to suppress the TMAO-induced atherosclerosis remains unexplored.

Trimethylamine N-Oxide (TMAO) Inducing Endothelial Injury: UPLC-MS/MS-Based Quantification and the Activation of Cathepsin B-Mediated NLRP3 Inflammasome

Molecules, 2023
TMAO is a new risk biomarker for cardiovascular disease. With trimethylammonium as its main chemical skeleton, TMAO is structurally similar to many endogenous metabolites, such as acetylcholine, carnitine, phosphorylcholine, etc. The mechanism of TMAO on

Microbiota-Derived Metabolite Trimethylamine N-Oxide Protects Mitochondrial Energy Metabolism and Cardiac Functionality in a Rat Model of Right Ventricle Heart Failure

Frontiers in Cell and Developmental Biology, 2021
Aim: Trimethylamine N-oxide (TMAO) is a gut microbiota-derived metabolite synthesized in host organisms from specific food constituents, such as choline, carnitine and betaine. During the last decade, elevated TMAO levels have been proposed as biomarkers

TMAO, a seafood-derived molecule, produces diuresis and reduces mortality in heart failure rats

eLife, 2020
Trimethylamine-oxide (TMAO) is present in seafood which is considered to be beneficial for health. Deep-water animals accumulate TMAO to protect proteins, such as lactate dehydrogenase (LDH), against hydrostatic pressure stress (HPS).

Aorta- and liver-generated TMAO enhances trained immunity for increased inflammation via ER stress/mitochondrial ROS/glycolysis pathways

JCI Insight, 2023
We determined whether gut microbiota-produced trimethylamine (TMA) is oxidized into trimethylamine N-oxide (TMAO) in nonliver tissues and whether TMAO promotes inflammation via trained immunity (TI).

Nonlethal Inhibition of Gut Microbial Trimethylamine N‐oxide Production Improves Cardiac Function and Remodeling in a Murine Model of Heart Failure

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Patients at increased risk for coronary artery disease and adverse prognosis during heart failure exhibit increased levels of circulating trimethylamine N‐oxide (TMAO), a metabolite formed in the metabolism of dietary phosphatidylcholine.
