The regulation of plasmin generation on cell surfaces is of critical importance in the control of vascular homeostasis. Cell-derived microparticles participate in the dissemination of biological activities. However, their capacity to promote plasmin generation has not been documented. In this study, we show that endothelial microparticles (EMPs) from tumor(More)
The MLL gene from human chromosome 11q23 is involved in >30 different chromosomal translocations resulting in a plethora of different MLL fusion proteins. Each of these tends to associate with a specific leukaemia type, for example, MLL-AF9 is found mainly in acute myeloid leukaemia. We have studied the role of the Mll-AF9 gene fusion made in mouse(More)
Results of thrombolysis by monotherapy with either tPA or proUK have not lived up to expectations. Since these natural activators are inherently complementary, this property can be utilized to a synergistic advantage; and yet, this has undergone little evaluation. ProUK is no longer available because at pharmacological concentrations it converts to UK in(More)
Endogenous urokinase-type plasminogen activator (u-PA) has been identified in platelet membrane, and platelets have been shown to take up exogenous high molecular weight u-PA from the ambient medium. In this report, the mechanism of the association of u-PA with platelets was investigated using recombinant, single chain u-PA. When gel filtered human(More)
