Research Abstract |
In the present study, using normal human pancreatic duct epithelial cells and cancer cell lines. we investigated the basic study targeting tight junction molecules claudin-4, -18 and a signal molecule PKC that highly expressed in pancreatic cancer. Claudin-4 and -18 were regulated via a PKCalpha signal transduction pathway in both human pancreatic duct epithelial cells and cancer cells. The cytotoxic effects of CPE via claudin-4 are thought to be useful as a novel therapeutic tool for pancreatic cancer. The cytotoxicity was not observed at any concentration of CPE, whereas in pancreatic cancer cells, CPE had a dose-dependent cytotoxic effect. PKCalpha inhibitors represent potential therapeutic agents against human pancreatic cancer cells by the use of CPE cytotoxicity via claudin-4.
