Interaction between the urokinase-type plasminogen activator (uPA) and its receptor (uPAR) localizes cellular proteolysis and promotes cellular proliferation and migration. The interaction between uPA and uPAR at the surface of epithelial cells thereby contributes to the pathogenesis of lung inflammation and neoplasia. In this study, we sought to determine if uPA itself alters uPAR expression by lung epithelial cells. uPA enhanced uPAR expression as well as (125)I-uPA binding in Beas2B lung epithelial cells in a time- and concentration-dependent manner. The uPA-mediated induction of uPAR is not accomplished through its receptor and requires enzymatic activity. The low molecular weight fragment of uPA, lacking the receptor binding domain, was as potent as intact two-chain uPA in inducing expression of uPAR at the cell surface. Plasmin, the end product of plasminogen activation, did not alter uPA-mediated uPAR expression. Induction of uPAR by uPA represents a novel pathway by which epithelial cells can regulate uPAR-dependent cellular responses that may contribute to stromal remodeling in lung injury or neoplasia.
