Urokinase-type plasminogen activator (uPA) activates the mitogen activated protein (MAP) kinases, extracellular signal-regulated kinase (ERK) 1 and 2, in diverse cell types. In this study, we demonstrate that uPA stimulates migration of MCF-7 breast cancer cells, HT 1080 fibrosarcoma cells, and uPAR-overexpressing MCF-7 cells by a mechanism that depends on(More)
The very low density lipoprotein receptor (VLDLr) binds diverse ligands, including urokinase-type plasminogen activator (uPA) and uPA-plasminogen activator inhibitor-1 (PAI-1) complex. In this study, we characterized the effects of the VLDLr on the internalization, catabolism, and function of the uPA receptor (uPAR) in MCF-7 and MDA-MB-435 breast cancer(More)
Cytokeratin 8 (K8) is a member of the intermediate filament (IF) gene family expressed by simple epithelial cells and by some carcinoma cells. The majority of the cellular K8 is assembled with its partner, K18, into highly insoluble 10 nm filaments that extend from the nucleus to the internal leaflet of the plasma membrane. At desmosomes and hemidesmosomes,(More)
