The tissue-specific distribution of tissue-type and urokinase-type plasminogen activator (t-PA and u-PA) and their inhibitor type 1 (PAI-1) was analyzed at mRNA level in five major rat organ tissues. t-PA mRNA was detected in lung, kidney, heart, and liver. u-PA mRNA was detected in kidney and lung. Presence of PA mRNA correlated with the...

In 22 human tumor cell lines the regulation of production of plasminogen activators urokinase (u-PA) and tissue-type (u-PA) and their inhibitors PAI-1 and PAI-2 was studied. These four components may determine the net plasminogen activator activity, which is often associated with tumor development and metastatic processes. The amount of specific...

Plasminogen activator (PA) and PA inhibitor (PAI) antigen, activity, and mRNA were analyzed in the three layers of rat aorta, and the effect of endotoxin on PA and PAI was studied. All PA activity in aorta was identified as tissue-type PA (TPA) activity; no urokinase-type PA was detected. In the tunica adventitia TPA activity, TPA antigen, and...

Culture medium conditioned by human SK-Hep1 hepatoma cells or mouse S180 sarcoma cells rapidly up-regulates endothelial cell expression of basic fibroblast growth factor (bFGF) and induces formation of capillary-like structures by vascular endothelial cells grown on three-dimensional fibrin gels (in vitro angiogenesis). Incubation of endothelial...

In the pathogenesis qf human tumors the capacity of tumor cells to form metastases is one of the most crucial events. Ther^ore, the unravelling of molecular mechanisms involved in the process of metastasis is very important. Next to a great number of other factors, extracellular proteases and adhesion molecules of the integrin superfamily...

Plasmin-mediated extracellular proteolysis has been implicated in the degradation of bone in normal and pathological conditions. Normal and malignant osteoblasts can produce both tissue-type plasminogen activator (t- PA) and urokinase-type plasminogen activator (u-PA). We have used the osteosarcoma cell line MG63 to address the question of...

Background: Lipopolysaccharide (endotoxin) has been shown to increase the expression of plasminogen activator inhibitor type-1 (PAI-1) in the vessel wall. Endotoxin is known to increase PAI-1 production in endothelial cells, but its action on smooth muscle cells (SMCs) is presently not clear. In this study we determined the effect of endotoxin...

The plasminogen activation (PA) system is involved in vascular remodelling. Modulating its activity in vascular cells might be a way to interfere in processes such as angiogenesis and restenosis. Adenoviral vectors have become a favourable tool for direct gene transfer into vascular cells. In the interest of using adenoviral vectors to modulate...

The objective of this study was to investigate the role of the plasminogen activation system in the migration of human vascular smooth muscle cells in vitro. After wounding of confluent human smooth muscle cell cultures by stripping cells from their extracellular matrix, cells start to migrate from the wounded edge into the denuded area....

The plasminogen activation system is thought to be important in cell migration processes. A role for this system during smooth muscle cell migration after vascular injury has been suggested from several animal studies. However, not much is known about its involvement in human vascular remodelling. We studied the involvement of the plasminogen...
