Inhibition of tumor invasion by genomic down-regulation of matriptase through suppression of activation of receptor-bound pro-urokinase.


Urokinase-type plasminogen activator (uPA) degrades the extracellular matrix and plays critical roles in tumor invasion and metastasis. Matriptase, a membrane-bound serine protease, was shown to activate uPA in a uPA receptor-free, solution-based study. We now investigate whether matriptase affects activation of receptor-bound uPA and contributes to the… (More)
