Plant Food Anthocyanins Induced Platelet Apoptosis Via Bcl-2/Bcl-Xl Pathway
BLOOD(2014)
摘要
Background: Platelets are versatile cells and play important roles in hemostasis/thrombosis, inflammation, and atherosclerosis. The pathogenesis of cardiovascular diseases (CVDs) is linked to platelet hyperactivity which is considered an independent risk factor for CVDs. Platelets are critical for promoting the progression of CVDs, and platelet apoptosis have been reported to be involved in platelet activation. Anthocyanins are major phytochemicals abundant in plant food and have been shown to play a protective role against CVDs. Our previous studies demonstrated that anthocyanins from plant food significantly inhibited platelet activation, adhesion, aggregation and granule secretion, as well as attenuated thrombus growth at both arterial and venous shear stresses in vitro and in vivo, however, the effects of anthocyanin on platelet apoptosis and its mechanisms have not been explored. In the present study, we examined whether anthocyanin Cyanidin-3-glucoside (Cy-3-g) affect platelet apoptosis and the BCL-2/BCL-XL intrinsic apoptotic pathway.
