Trimethylamine N-oxide promotes tissue factor expression and activity in vascular endothelial cells: A new link between trimethylamine N-oxide and atherosclerotic thrombosis

Abstract

Trimethylamine-N-oxide (TMAO), one of the products in choline metabolite, is recently reported to be associated with cardiovascular diseases (CVD) that mainly attribute to atherothrombosis. However, the mechanisms how TMAO functions in the pathogenesis of CVD and atherothrombosis remain elusive. Tissue factor (TF) has been implicated in the thrombogenicity of atherosclerotic plaques. In the present study, we demonstrated that TMAO promoted TF (but not TF pathway inhibitor) expression via activation of NF-κB signaling pathway in primary human coronary artery endothelial cells (HCAECs). TMAO strongly increased TF activity and thrombin production. Further, a small dose of TMAO significantly increased TF expression and nuclear translocation of NF-κB with the synergistic action of low-dose of pro-atherosclerotic factors, such as TNF-α and HMGB1. Importantly, plasma TMAO level was positively correlated with TF activity in patients with ST-elevation myocardial infarction (STEMI). Altogether, our data revealed that TMAO promoted thrombosis through increasing TF expression and activity. The understanding of the new link between TMAO and atherothrombosis may facilitate therapeutic strategy in the prevention and treatment of atherothrombosis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
