The potential for hepatic metastasis in nude mice was studied by the intrasplenic implatation method with three human pancreatic cancer cell lines, Capan-1, BxPC-3, and MIAPaCa-2, especially in relation to serine protease expression. The inhibitory effect of a protease inhibitor agent, FOY-305, on hepatic metastasis was also assessed. In addition, we examined these cell lines, for expression of he vacuolar type proton pump (V-type ATPase), and determined the effect of its inhibitor agent, bafilomycin A1, on the cancer cell invasion in vitro by chemoinvasion assay using a MATRIGEL invasion chamber.The potential for hepatic metastasis was well correlated with expression of trypsinogen l (cationic isoform) in these cell lines, and the incidence of metastasis was significantly decreased by FOY-305. In addition, the potential for invasion in vitro in these cell lines was also siginificantly suppressed by bafilomycin A1. These finding suggest that pharmacologic inhibition of the activity of serine protease and V-type ATPase may be a new strategy for the therapy of pancreatic cancer invasion and metastasis.}, pages = {888--892}, title = {Protease inhibitor および proton pump inhibitor を用いた膵癌治療に対する新しい制癌治療戦略}, volume = {29}, year = {1996} }
