| Outline of Final Research Achievements |
In order to make baseline of new anti-angiogenic therapy for glioblastoma, we focused on neurovascularar wiring factors. Among neurovascular wiring factors, we found that slit2 expressed in glioblastoma associated with marked angiogenesis and promoted glioblastoma induced angiogenesis using glioblastoma tissues and cell lines. On therapeutic point, lenalidomide inhibited slit2 mRNA expression and chetomin inhibited cell growth under hypoxia and HIF-1α protein expression. Combined therapy with inhibitors of neurovascular wiring factor, slit2 and HIF-1α promise growth inhibition for glioblastoma.
