Demonstration of the extrinsic coagulation pathway in teleostei: identification of zebrafish coagulation factor VII.
It is not known whether the mammalian mechanism of coagulation initiation is conserved in fish. Identification of factor VII is critical in providing evidence for such a mechanism. A cDNA was cloned from a zebrafish (teleost) library that predicted a protein with sequence similarity to human factor VII. Factor VII was shown to be present in zebrafish blood and liver by Western blot analysis and...
متن کاملAcquired deficiency of coagulation factor VII
Factor VII (FVII) is found in small amounts in plasma and has a very short half-life in circulation. FVII is vitamin K-dependently synthesized in the liver. As such, hepatopathies, vitamin K deficiency, or use of vitamin K antagonists is the cause of acquired deficiency. Other types of acquired FVII deficiencies are rare.1 Here we describe a case of acquired factor VII deficiency associated to ...
متن کاملTissue factor-dependent autoactivation of human blood coagulation factor VII.
We recently showed that single-chain zymogen factor VII is converted to two-chain factor VIIa in an autocatalytic manner following complex formation with either cell-surface or solution-phase relipidated tissue factor apoprotein (Nakagaki, T., Foster, D. C., Berkner, K. L., and Kisiel, W. (1991) Biochemistry 30, 10819-10824). We have now performed a detailed kinetic analysis of the autoactivati...
متن کاملAn alternative extrinsic pathway of human blood coagulation.
To study the interrelationships of the major human coagulation pathways, factor X activation in normal and various deficient human plasmas was evaluated when clotting was triggered by dilute rabbit or human thromboplastin. Various dilutions of thromboplastin were added to plasma samples containing 3H-labeled factor X, and the time course of factor X activation was determined. At a 1/250 dilutio...
متن کاملActivation of coagulation factor VII during alimentary lipemia.
Dietary studies have established a connection between plasma lipoproteins and coagulation factor VII. The present study was undertaken to specifically examine whether factor VII is activated during alimentary lipemia and to investigate the relations of factor VII mass and activity state with fasting and postprandial lipoproteins and free fatty acids (FFAs). Factor VII levels were therefore dete...
