background: streptokinase is a bacterial protein produced by different beta hemolytic streptococci and widely used in thrombolytic treatment. the main disadvantage of using streptokinase is antibody formation which causes allergic reaction to neutralize effects of streptokinase therapy. aim of this study was investigate of recombinant mutant streptokinase fibrinolytic activity. m aterials and m...
A sensitive immunological assay for plasminogen and/or plasmin was developed by using a haemagglutination inhibition technique. Plasma and the corresponding euglobulin fraction of healthy subjects and of patients with hyperfibrinolysis (liver cirrhosis, thrombolytic treatment) were assayed for plasminogen using immunological and caseinolytic techniques. In hyperfibrinolytic states discrepancies...
To test the hypothesis that Helicobacter pylori regulates gastric cell secretion of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs), culture media from infected and uninfected human gastric adenocarcinoma (AGS) cells were analyzed by zymography, MMP activity assays, and immunoblotting. AGS cells secreted gelatinolytic (prominently 90 kDa) and caseinolytic (1...
Development of the aleurone layer of maize grains requires the activity of the Defective kernel 1 (Dek1) gene, encoding a predicted 240-kDa membrane-anchored protein with a C terminus similar to animal calpain domain II&III. Three-dimensional modeling shows that DEK1 domain II contains a conserved calpain catalytic triad and that domain II&III has a predicted structure similar to m-calpain. Rec...
We have examined the ability of 5 tumour cell types to attach to plastic flasks in medium containing either 10% foetal calf serum or 10% normal human serum and compared this ability with cell-associated caseinolytic activity. The cell types used included fibrosarcoma cells which were obtained from a methylcholanthrene-induced tumour in a C57 BL/6 mouse, the SV40-transformed 3T3 (BALB/c) cells, ...
Using a phage library, seven peptide sequences with high affinity to human microplasminogen were obtained. Caseinolytic assay indicated that only the synthesized peptide P07 had slight fibrinolytic activity. To enhance its plasminogen activation ability, peptide P07 was fused into loop 32-35 of hirudin. In vitro assay demonstrated that this hirudin-like fusion protein can activate human plasmin...
The caseinolytic activity of several strains of Rous sarcoma virus (RSV), conditional and nonconditional mutants of RSV, and nontransforming avian leukosis viruses was investigated. Only those viruses capable of transforming chick fibroblasts in vitro induced lysis of casein incorporated into an agar overlay. Lysis produced distinct clear areas in the turbid casein-agar gel which allowed a quan...
