| Outline of Final Research Achievements |
Over the last decade, we have developed computational models to interpret instructive cell signaling and high-throughput transcriptome-wide behaviors of immune and cancer cells. Here, we focused to overcome cancer resistance. TRAIL (tumor necrosis factor related apoptosis-inducing ligand), a proinflammatory cytokine, has shown promising success in controlling cancer threat due to its ability to induce apoptosis in cancers specifically, while having limited effect on normal cells. Nevertheless, several malignant cancers, such as fibrosarcoma (HT1080), remain non-sensitive to TRAIL. To sensitize HT1080 to TRAIL treatment, we developed a dynamic computational model based on perturbation-response approach, to predict a crucial co-target to enhance cell death. The model simulations suggested that PKC inhibition together with TRAIL induce 95% cell death. Subsequently, we confirmed this result experimentally utilizing the PKC inhibitor, bisindolylmaleimide (BIM) I, and PKC siRNAs in HT1080.
