Abstract

Objective—: Plant-derived α-linolenic acid (ALA) may constitute an attractive cardioprotective alternative to fish-derived n -3 fatty acids. However, the effect of dietary ALA on arterial thrombus formation remains unknown. Methods and Results—: Male C57Bl/6 mice were fed a high-ALA or low-ALA diet for 2 weeks. Arterial thrombus formation was delayed in mice fed a high-ALA diet compared with those on a low-ALA diet (n=7; P <0.005). Dietary ALA impaired platelet aggregation to collagen and thrombin (n=5; P <0.005) and decreased p38 mitogen-activated protein kinase activation in platelets. Dietary ALA impaired arterial tissue factor (TF) expression, TF activity, and nuclear factor-κB activity (n=7; P <0.05); plasma clotting times and plasma thrombin generation did not differ (n=5; P =not significant). In cultured human vascular smooth muscle and endothelial cells, ALA inhibited TF expression and activity (n=4; P <0.01). Inhibition of TF expression occurred at the transcriptional level via the mitogen-activated protein kinase p38 in smooth muscle cells and p38, extracellular signal-regulated kinases 1 and 2, and c-Jun N-terminal kinases 1 and 2 in endothelial cells. Conclusion—: ALA impairs arterial thrombus formation, TF expression, and platelet activation and thereby represents an attractive nutritional intervention with direct dual antithrombotic effects.

  • The findings for ALA are mechanistically supported by effects of ALA on thrombosis, inflammation, arrhythmia, and endothelial function.

    “Mechanistically, these findings are supported by effects of ALA on thrombosis, inflammation, arrhythmia, and endothelial function.43–47”
  • Higher brain levels of omega-3 PUFAs and their atherosclerotic plaque stabilizing, anti-venous thrombosis, anti-inflammatory, antiplatelet, and anticoagulant properties result in fewer risks for embolism and plaque rupture.

    “Higher brain levels of omega 3 PUFAs and their atherosclerotic plaque stabilizing properties, as well as their anti-venous thrombosis, anti-inflammatory, antiplatelet, and anticoagulant properties, result in fewer risks for embolism and plaque rupture [20,[78][79][80].”

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.
