Molecular competition between plasminogen activator inhibitors type -1 and -2 for urokinase: Implications for cellular proteolysis and adhesion in cancer

Lobov, Sergey; Ranson, Marie


Up-regulation of the urokinase plasminogen activation (uPA) system leads to increased cancer invasion and metastasis. Plasminogen activator inhibitors type-1 (PAI-1/SERPINE1) and type-2 (PAI-2/SERPINB2) have similar uPA inhibitory properties yet PAI-1 promotes cell invasion by modulating cell adhesion and migration. High tumour PAI-2 levels are associated with improved prognoses. Herein we show that PAI-2 is capable of inhibiting uPA in the presence of PAI-1, particularly on adherent cells in...[Show more]
