Plasminogen activators and plasminogen activator inhibitors in endometriosis
Frontiers in Bioscience, 2005Endometriosis is one of the most frequent benign gynecological diseases that affect women. Little is known about the pathogenesis and etiology of endometriosis, despite the numerous studies performed in this field. Although endometriosis is a benign disease, the endometrial tissue, after attachment to the peritoneum, has the ability to grow and invade ...

Glu-plasminogen (Glu-plg), Lys-plg and Val442-plg (mini-plg) were activated by urokinase (UK), streptokinase (SK) or tissue plasminogen activator (t-PA). Their activation rates were kinetically analyzed. UK activated Lys-plg with smaller Km and nearly identical Vmax as Glu-plg.

Studies on the kinetics of plasminogen activation by tissue plasminogen activator
BBA - Proteins and Proteomics, 1982The steady-state rate of plasminogen activation by tissue plasminogen activator has been determined at various plasminogen concentrations. A plasmin substrate method similar to that presented by Christensen and Müllertz (Biochim. Biophys. Acta 480 (1977) 257-281) was used.

The potentiating effect of fibrin monomer on plasminogen activation by tissue-type plasminogen activator is much more important with lys-plasminogen than with mini-plasminogen (which lacks the high affinity lysine-binding site important for binding to fibrin).

The conformations of Glu-plasminogen and defined proteolytic fragments, in the presence and absence of 6-aminohexanoic acid (6-AHA), trans-4-(aminomethyl)cyclohexanecarboxylic acid (t-AMCHA), and benzamidine, were studied using three methods: size-exclusion high-performance liquid chromatography (SE-HPLC), small-angle X-ray scattering (SAXS), and ...

Annexin II: a plasminogen-plasminogen activator co-receptor
Frontiers in Bioscience, 2002Fibrinolysis is a precisely orchestrated process in which fibrin-containing thrombi are solubilized. Several receptors regulate this process by localizing proteolytic activity to the cell surface. One such receptor is annexin II, a calcium and phospholipid-binding protein.

Activation of Bovine Plasminogen by the Plasminogen Activator in Animal Tissue
Thrombosis and Haemostasis, 1960Summary1. The activation of bovine plasminogen by means of the plasminogen activator from pig heart tissue has been studied on heated fibrin and on casein.2. Small, but varying, amounts of activator can be extracted from crude activator powder during the experiment and interfere therefore with estimations on normal, plasminogen containing fibrin.3. The

Fluorescence polarization assay of plasmin, plasminogen, and plasminogen activator
Analytical Biochemistry, 1980Abstract We describe two assay methods for plasminogen activator (urokinase) employing the fluorescence polarization technique. One method utilizes fluoroscein isothiocyanate-labeled plasminogen as the substrate for urokinase (direct method), and the other utilizes the new plasmin generated from plasminogen by urokinase, for which fluoroscein ...

Plasminogen/plasminogen activator and growth factor activation.
Ciba Foundation symposium, 1997The plasminogen/plasminogen activator system is widely used in extracellular proteolysis. In this review the involvement of this system in tumour invasion, cell migration, growth factor presentation and inhibition of angiogenesis are discussed.

STUDIES ON PLASMINOGEN: I. FURTHER PURIFICATION OF BOVINE PLASMINOGEN
Canadian Journal of Biochemistry and Physiology, 1961Crude bovine plasminogen, prepared from bovine serum by 30% saturation with ammonium sulphate, was partially purified by isoelectric precipitation at pH 5.3, then purified by chromatography on columns of diethylaminoethyl-cellulose. Additional purification of the column product was obtained by precipitation of plasminogen from solution with potassium ...
