Research Abstract |
We performed preclinical studies to establish the novel gene therapy for pancreatic cancer using adenovirus expressing NK4, which is antagonist of HGF. We confirmed the safety of adno-NK4 using animal models. (2) We investigated the effect of combination therapy with gemcitabine and adeno-NK4 and demonstrated that synergistic effect of this therapy. (3)We revealed that trans-portal adeno-NK4 administration significantly inhibited the liver metastasis of pancreatic cancer in mouse models. (4) We developed novel drug delivery system using cell-sheet expressing NK4 and showed that the novel DDS controlled local progression of pancreatic cancer in mouse models. (5)We found the novel inhibitory effect of combination therapy with gemcitabine and fibrin glue and performed and continued the clinical trials using this therapy. (6) We developed rapid diagnostic system for pancreatic juice samples. (7.8) We clarified the mechanism of adenovirus-based gene therapy enhanced by gemcitabine or radiation.(9)We found that tert-promotor-medated CRAds therapy was also enhanced by gemcitabine or other anticancer agents.
