Plasminogen activator inhibitor-1 regulates tumor growth and angiogenesis.
Elevated expression of plasminogen activator inhibitor-1 (PAI-1) in tumors is associated with a poor prognosis in many cancers. Reduced tumor growth and angiogenesis have also been reported in mice deficient in PAI-1. These results suggest that PAI-1 may be required for efficient angiogenesis and tumor growth. In the present study, we demonstrate that PAI-1 can both enhance and inhibit the grow...
متن کاملTargeting plasminogen activator inhibitor-1 inhibits angiogenesis and tumor growth in a human cancer xenograft model.
Cancers of the urinary bladder result in aggressive and highly angiogenic tumors for which standard treatments have only limited success. Patients with advanced disease have a 5-year survival rate of less than 20%, and no new anticancer agent has been successfully introduced into the clinic armamentarium for the treatment of bladder cancer in more than 20 years. Investigations have identified p...
متن کاملSK-216, an inhibitor of plasminogen activator inhibitor-1, limits tumor progression and angiogenesis.
Plasminogen activator inhibitor-1 (PAI-1), which can be produced by host and tumor cells in the tumor microenvironment, is intimately involved in tumor progression. In the present study, to pursue the possibility that PAI-1 could be a therapeutic target in the management of malignancy, SK-216, a specific PAI-1 inhibitor, was orally administered to wild-type mice that were subcutaneously implant...
متن کاملEstrogen regulates endothelial migration via plasminogen activator inhibitor (PAI-1).
Endothelial plasminogen activator inhibitor (PAI-1) controls vascular remodeling, angiogenesis and fibrinolysis. PAI-1 blood levels in women are related to estrogen. The aim of this study was to characterize the signaling pathways through which estrogen regulates PAI-1 in endothelial cells. Furthermore, we aimed to investigate whether PAI-1 is implicated in the control of endothelial migration ...
متن کاملPlasminogen activator inhibitor-1 regulates myoendothelial junction formation.
RATIONALE Plasminogen activator inhibitor-1 (PAI-1) is a biomarker for several vascular disease states; however, its target of action within the vessel wall is undefined. OBJECTIVE Determine the ability of PAI-1 to regulate myoendothelial junction (MEJ) formation. METHODS AND RESULTS MEJs are found throughout the vasculature linking endothelial cells (ECs) and vascular smooth muscle cells. ...
