Daily and circadian rhythms of tissue factor pathway inhibitor and factor VII activity.
OBJECTIVE Diurnal variations in levels of factor VII (FVII), FVIII, proteins C and S, antithrombin, plasminogen activator inhibitor-1, prothrombin fragment F1+2, and D-dimers in healthy humans point to the existence of circadian rhythms of coagulation factors. We sought for temporal fluctuations of tissue factor pathway inhibitor (TFPI) activity in human and mouse plasma. METHODS AND RESULTS ...
متن کاملFactor VII-activating protease promotes the proteolysis and inhibition of tissue factor pathway inhibitor.
OBJECTIVE Factor VII-activating protease (FSAP) activates both factor VII and pro-urokinase and inhibits platelet-derived growth factor-BB, thus regulating hemostasis- and remodeling-associated processes in the vasculature. A genetic variant of FSAP (Marburg I polymorphism) results in low enzymatic activity and is associated with an enhanced risk of carotid stenosis and stroke. We postulate tha...
متن کاملEffects of combined oral hormone replacement therapy on tissue factor pathway inhibitor and factor VII.
Oral combined hormone replacement therapy (HRT) with oestradiol and norethisterone increases plasma levels of prothrombin fragment 1+2 (F1+2), indicating an increase in thrombin generation, but the mechanisms underlying this increase are uncertain. The aim of this randomized, placebo-controlled study was to determine whether an increase in factor VII, a factor that combines with tissue factor t...
متن کاملCaveolae optimize tissue factor-Factor VIIa inhibitory activity of cell-surface-associated tissue factor pathway inhibitor.
TFPI (tissue factor pathway inhibitor) is an anticoagulant protein that prevents intravascular coagulation through inhibition of fXa (Factor Xa) and the TF (tissue factor)-fVIIa (Factor VIIa) complex. Localization of TFPI within caveolae enhances its anticoagulant activity. To define further how caveolae contribute to TFPI anticoagulant activity, CHO (Chinese-hamster ovary) cells were co-transf...
متن کاملEnhancement of lipoprotein lipase activity by tissue factor pathway inhibitor.
The effect of a basic synthetic peptide, representing the C-terminal region of tissue factor pathway inhibitor (TFPI - Lys254 - Met276), as well as that of the whole protein, on the activity of lipoprotein lipase (LPL) is described. The activity of bovine LPL was measured by chromogenic assay using a water-soluble chromogenic substrate, p-nitrophenyl butyrate. Five and 10 microM concentrations ...
