| Outline of Final Research Achievements |
Nuclear Factor-kappa B is activated by carcinogens, tumor promoters, inflammatory cytokines, and chemotherapeutic agents. We focused on anti-tumorigenesis and anti-inflammation effects by means of inhibition of NF-κB activity. ①We revealed that (1)molecular target agent (IMD-0354) suppressed constitutive NF-κB activity, (2)gemcitabine stimulated NF-κB activity, and (3)combined therapy of IMD-0354 and gemcitabine revealed enhanced anti-tumor effects. ②We investigated a swine model to assess the invasiveness of surgical stress. In this model, inferior vena cava, aorta, the trunks of celiac artery and superior mesenteric artery were exposed. Intraoperative hemodynamics were monitored at the stable points after clamping each vessels, respectively. Inhibition of NF-κB activity in this model is still ongoing.
