Profile of blood coagulation and fibrinolysis in chronic myeloproliferative disorders.

Blood coagulation, fibrinolysis and exercise.

Fibrinolysis and the control of blood coagulation.

Fibrin plays an essential role in hemostasis as both the primary product of the coagulation cascade and the ultimate substrate for fibrinolysis. Fibrinolysis efficiency is greatly influenced by clot structure, fibrinogen isoforms and polymorphisms, the rate of thrombin generation, the reactivity of thrombus-associated cells such as platelets, and the overall biochemical environment. Regulation ...

Blood Coagulation, Fibrinolysis and Cellular Haemostasis Introduction

A high plasma concentration of coagulation factor VIII (FVIII) is an important risk factor for venous thromboembolism (VTE) (1-4). In the Leiden Thrombophilia study for example, FVIII levels above 1500 IU/L conferred an almost 5-fold risk for a first episode of deep-vein thrombosis (1). Most importantly, high FVIII is also associated with a very high risk of recurrent venous thromboembolism (4,...

Polyphosphate modulates blood coagulation and fibrinolysis.

Inorganic polyphosphate is an abundant component of acidocalcisomes of bacteria and unicellular eukaryotes. Human platelet dense granules strongly resemble acidocalcisomes, and we recently showed that they contain substantial amounts of polyphosphate, which is secreted upon platelet activation. We now report that polyphosphate is a potent hemostatic regulator, accelerating blood clotting by act...

Chronic Myeloproliferative Disorders

JAK2, an acquired mutation of JAK2, is present in a majority of patients with polycythemia vera and to a lesser extent among patients with the other myeloproliferative disorders. We analyzed the effect of JAK2 on the expression of polycythemia rubra vera 1(PRV-1), using an in vitro model. Compared to wild-type JAK2, the presence of JAK2 increased both PRV-1 protein and mRNA levels in murine mye...
