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...

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...

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...

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...
