Could coenzyme Q10 affect hemostasis by inhibiting platelet vitronectin (CD51/CD61) receptor?

Journal Article

Improved cardiovascular morbidity and mortality have been observed in several clinical studies of dietary supplementation with coenzyme Q10 (CoQ10, ubiquinone). Several mechanisms have been proposed to explain the effects of CoQ10. One attractive theory links ubiquinone with the inhibition of platelets. The effect of CoQ10 intake on platelet surface antigens, and certain hemostatic parameters was examined in 15 humans and 10 swine. Study participants received 100 mg of CoQ10 twice daily in addition to their usual diet for 20 days resulting in a three-fold increase of total serum CoQ10 level. We observed a decline in plasma fibronectin (-20.2%), thromboxane B2 (-20.6%), prostacyclin (-23.2%), and endothelin-1 (-17.9%) level. Significant inhibition of vitronectin receptor expression was observed consistently throughout ubiquinone treatment. Inhibition of the platelet vitronectin receptor is a direct evidence of a link between dietary CoQ10 intake, platelets, and hemostasis. These findings may contribute to the observed clinical benefits by a diminished incidence of thrombotic complications in such patients.
