Total saponin from Korean red ginseng inhibits binding of adhesive proteins to glycoprotein IIb/IIIa phosphorylation of VASP (Ser) and dephosphorylation of PI3K and Akt

Binding of adhesive proteins (i.e. fibrinogen, fibronectin, vitronectin) to platelet integrin glycoprotein IIb/IIIa (αIIb/β3) by various agonists (thrombin, collagen, ADP) involve in strength of thrombus. This study was carried out to evaluate antiplatelet effect of total saponin from Korean red ginseng (KRG-TS) by investigating whether KRG-TS inhibits thrombin-induced binding of fibrinogen and fibronectin to αIIb/β3.
