| Outline of Final Research Achievements |
Although it has been known that neuropilin1 (NRP1) has a promoting effect in vascularization, which is critical process in growth and progression of malignant tumors, the function of NRP1 in neuroblastoma cells is still unclear. In the present study, we conducted functional analyses of NRP1 to elucidate its roles in the development and/or promotion of neuroblastoma. In addition, we synthesized pyrrole imidazole polyamides (PIP) targeting to NRP1, and investigated its potential as therapeutic agents for neuroblastoma. Our current result demonstrated that the PIPs we designed did not suppress the expression of NRP1 in neuroblastoma cells. SiRNA mediated silencing of NRP1 in neuroblastoma derived SK-N-AS cells resulted in up-regulation of Integrin b1, and promotion of cell migration and invasion.
