title: [Inhibitory effect of FOY-305 on liver metastasis of the pancreatic cancer].
abstract: The potential for hepatic metastasis in nude mice was studied by the intrasplenic implantation method with five human pancreatic cancer cell lines, Capan-1, BxPC-3, AsPC-1, Panc-1, and MIAPaCa-2, especially in relation to serine protease expression, including urokinase-type plasminogen activator and pancreatic trypsinogen 1 (cationic form). The inhibitory effect of a serine protease inhibitor agent, FOY-305, on hepatic metastasis was also a assessed. As a result, the potential for hepatic metastasis was well correlated with expression of pancreatic trypsinogen 1 in these cell lines, and the incidence of metastasis was significantly decreased by FOY-305. These findings suggest that pharmacologic inhibition of serine protease activity may be a new strategy for the therapy of pancreatic cancer metastasis.
