Inhibitors of Factor VIIa/tissue factor.
The formation of the proteolytic complex composed of the serine protease Factor VIIa and the cell-associated glycoprotein tissue factor (FVIIa/TF) initiates a cascade of amplified zymogen activation reactions leading to thrombus formation. The critical role of the coagulation cascade in pathological thrombosis has been the basis for significant efforts to design selective inhibitors of the prot...
متن کاملBinding of factor VIIa to tissue factor permits rapid antithrombin III/heparin inhibition of factor VIIa.
Because free factor VIIa is inactivated only very slowly by a plasma concentration of antithrombin III (AT III) even in the presence of heparin, it has been assumed that AT III plays no significant role in regulating the initiation of tissue factor-dependent blood coagulation. However, in the present study, we present evidence that factor VIIa bound to tissue factor, unlike free factor VIIa, is...
متن کاملTissue factor/factor VIIa inhibitors block angiogenesis and tumor growth through a nonhemostatic mechanism.
An association between cancer and thrombosis has been recognized for more than a century. However, the manner by which tumor growth is regulated by coagulation in vivo remains unclear. To assess the role of coagulation on tumor growth, in vivo, we tested coagulation inhibitors specific for either tissue factor (TF)/factor VIIa (fVIIa) complexes or factor Xa (fXa) for antitumor activity. Here, w...
متن کاملHuman monocytes support factor X activation by factor VIIa, independent of tissue factor: implications for the therapeutic mechanism of high-dose factor VIIa in hemophilia.
High doses of recombinant factor VIIa are useful in managing bleeding in hemophiliacs with inhibitors. Whether this therapeutic effect of factor VIIa is dependent on tissue factor (TF) is a matter of debate. We examined the ability of freshly isolated human monocytes (which lack TF) to support the activation of coagulation-factor X by factor VIIa. The rate of factor-X activation by factor VIIa ...
