The fibrinolytic function of endothelial cells plays an important role in the pathophysiology of pulmonary vascular diseases. In this study, the effects of pro-urokinase, a new thrombolytic drug that is currently being tested for the treatment of pulmonary embolism, on the expression of urokinase-type plasminogen activator (u-PA) and u-PA receptor (u-PAR) were assessed. The role of u-PAR was also investigated. Immunocytofluorescence and RT-PCR techniques were employed. In normal human pulmonary arterial endothelial cells (HPAECs), the expression levels of u-PA and u-PAR were very low. Incubation with pro-urokinase up-regulated u-PA expression at both the mRNA level and the protein level; however, the expression of u-PAR was not affected. The effect of pro-urokinase induction was totally inhibited by the release of u-PAR from the HPAECs' surface with PLC. This result suggests that the combination of u-PA with u-PAR may be a critical pathway for the induction of u-PA expression.
