| Outline of Final Research Achievements |
We have been working on the study of innate signaling via pattern recognition mediated receptor for antiviral responses. In this study, we identified a novel innate signaling pathway via cytosolic RNA sensor RIG-I that activates cell death in cancer cells but not normal cells. This novel pathway is different from conventional pathway via MAVS/IPS-1 mediated IFN inducing pathway. Importantly, localization of a kinase protein is not only nucleus but also cytosol in cancer cells while the localization of this is only nucleus in normal cells. RIG-I in cancer cells activate this kinase and activates apoptosis in cancer cells. Based on our finding that a kinase is localized in cytosol of cancer cells, we propose a novel strategy to modulate ectopic protein for cancer therapy for cancer cells' death.
