| Outline of Final Research Achievements |
Elucidation of mechanisms underlying angiogenesis is important for the development of new anti-angiogenic drugs. Here, we found that EIF3D, a critical translational factor, is ubiquitinated by the cullin-3 (CUL3)/KCTD10 ubiquitin ligase complex in both endothelial cells and hepatocellular carcinoma cells. Knockdown of EIF3D in endothelial cells drastically inhibited tube formation of endothelial cells, that mimics angiogenesis in vitro. Our results suggest that CUL3/KCTD10/EIF3D would be a promising target for development of novel anti-angiogenic drugs.

| Academic Significance and Societal Importance of the Research Achievements |
現在、臨床応用されている血管新生阻害剤は全て血管内皮細胞増殖因子 (VEGF)または、VEGF受容体を標的としている。より効果的な癌治療を進めるためには、血管新生阻害剤のレパートリーを拡充する必要がある。今後、本研究で明らかにしたCUL3/KCTD10/EIF3D複合体を標的とした新しい血管新生阻害剤の開発が期待される。
