To delineate the role of binding of urokinase type plasminogen activator (uPA) to its receptor (uPAR) in the local generation of plasmin by endothelium, we transfected spontaneously transformed immortalized human vascular endothelial cells that express high levels of uPA but low levels of uPAR with

β¦ Synopsis
uPAR is highly expressed during tissue reorganization, inflammation, and in virtually all human cancers. Since its discovery, in vitro and in vivo models, as well as retrospective clinical studies have shown that overβexpression of components of the uPA/uPARβsystem correlates with increased proliferation, migration, and invasion affecting the malignant phenotype of cancer. uPAR regulates the cellsβextracellular matrix interactions promoting its degradation and turnover through the plasminogen activation cascade.
