The present study compared the activities of recombinant tissue-type plasminogen activator (t-PA) and a plasminogen activator inhibitor-1 (PAI-1)-resistant variant t-PA (Kt-PA, KHRR 296-299 AAAA) in preventing renal fibrin deposition in rabbits with elevated PAI-1 activity. In this model, all rabbits were infused with endotoxin (10 micrograms/kg), followed by initiation of thrombin (130 U/kg) 4...
IN AUGUST 1983, it was anticipated from biochemical observations and physiologic results in experimental animals that human tissue-type plasminogen activa-tor (t-PA) held considerable promise as a clot-specific, coronary thrombolytic agent for patients with acute myocardial infarction.' This anticipation has been fulfilled remarkably promptly by clinical research.2-1 Recently reported results f...
Retroviral vector-mediated expression of plasminogen activators (PAs) from endothelial cells (ECs) has been proposed as a potential therapeutic approach for intravascular thrombosis. To define the potential for gene transfer to increase fibrinolytic activity in a primate system, baboon ECs were transduced with retroviral vectors expressing wild-type and glycosylphosphatidylinositol-anchored uro...
Granulocyte-macrophage colony-stimulating factor (GM-CSF) raised the plasminogen activator (PA) activity of cultured human monocytes. This activity was characterized to be urokinase-PA (u-PA) by incubation with specific IgG and by sodium dodecyl sulfate-polyacrylamide gel electrophoresis zymography. Increased u-PA activity reflected GM-CSF-induction of u-PA mRNA levels. The stimulatory properti...
OBJECTIVE Socio-economic status (SES) has been positively associated with physical activity (PA) levels in adolescents. In order to tackle these social inequalities, information is needed about the underlying mechanisms of this association. The present study aimed to investigate the potential mediating role of psychosocial correlates of PA on the relationship between SES and PA in European adol...
Urokinase-type plasminogen activator (u-PA) is a key protease in cancer invasion and metastasis. Recent studies demonstrated that u-PA, plasminogen activator inhibitor type-1 (PAI-1), and tissue-type plasminogen activator (t-PA) are prognostic factors in breast cancer. However, there have been no prospective studies of node-negative breast cancer on a multicenter basis. On the other hand, some ...
Tissue-type plasminogen activator (t-PA ) plays an important role in the removal of intravascular fibrin deposits and has several physiological roles and pathological activities in the brain. Its production by many other cell types suggests that t-PA has additional functions outside the vascular and central nervous system. Activity of t-PA is regulated at the level of its gene transcription, it...
Therapeutic fibrinolysis has been dominated by the experience with tissue-type plasminogen activator (t-PA), which proved little better than streptokinase in acute myocardial infarction. In contrast, endogenous fibrinolysis, using one-thousandth of the t-PA concentration, is regularly lysing fibrin and induced Thrombolysis In Myocardial Infarction flow grade 3 patency in 15% of patients with ac...
Exercise to exhaustion was associated with the appearance in plasma of plasminogen activator (PA) in several mol wt forms, as identified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) with zymography. A number of active bands, all immunologically identified as tissue-type PA (t-PA), were observed. The major form had an apparent mol wt of approximately 60,000 and is due ...
