Urokinase-type plasminogen activator induces proliferation in breast cancer cells.
Urokinase-type plasminogen activator (uPA) is implicated in various pathophysiological processes, including extracellular matrix turnover, cell migration and invasion. Our study aimed to determine the role of uPA in both proliferation and mitogen-activated protein kinase (MAPK) pathway. Hence, we analyzed the effects induced by exogeneous addition of domain-specific uPA antibodies and uPA-inter...
متن کاملUrokinase-type plasminogen activator system in breast cancer: association with tamoxifen therapy in recurrent disease.
The prognostic value of components of the urokinase-type plasminogen activator (uPA) system, its receptor uPAR (CD87), and plasminogen activator inhibitors PAI-1 and PAI-2 is well established. We studied the predictive value of these proteolytic factors by evaluating the association of their tumor expression level and the efficacy of tamoxifen therapy in patients with recurrent breast cancer. T...
متن کاملMaspin retards cell detachment via a novel interaction with the urokinase-type plasminogen activator/urokinase-type plasminogen activator receptor system.
It is well documented that tumor suppressive maspin inhibits tumor cell invasion and extracellular matrix remodeling. Maspin is a cytosolic, cell surface-associated, and secreted protein in the serine protease inhibitor superfamily. Although several molecules have been identified as candidate intracellular maspin targets, the extracellular maspin target(s) remains elusive. Although maspin does ...
متن کاملUrokinase plasminogen activator (uPA) and plasminogen activator inhibitor type-1 (PAI-1) in breast cancer - correlation with traditional prognostic factors
BACKGROUND Urokinase plasminogen activator (uPA) and plasminogen activator inhibitor type-1 (PAI-1) play a key role in tumour invasion and metastasis. High levels of both proteolytic enzymes are associated with poor prognosis in breast cancer patients. The purpose of this study was to evaluate the correlation between traditional prognostic factors and uPA and PAI-1 expression in primary tumour ...
متن کاملInhibition of urokinase-type plasminogen activator expression by dihydroartemisinin in breast cancer cells
The aim of the present study was to investigate the inhibitory effects of dihydroartemisinin (DHA) on the primary tumor growth and metastasis of the human breast cancer cell line, MDA-MB-231, in vitro. The expression levels of urokinase-type plasminogen activator (uPA) were detected by immunocytochemistry in two cell lines (MCF-7 and MDA-MB-231). The MDA-MB-231 cell activity was inhibited by va...
