Outline of Final Research Achievements

This study focuses on functions of the membrane domains (lipid rafts) formed by glycolipids (gangliosides) on tumor cells. Fluorescent gangliosides have been developed by chemical synthesis and applied for single-molecule imaging on the cells. The results revealed significant interactions of gangliosides to understand the functions of lipid rafts and their formation mechanisms.

Academic Significance and Societal Importance of the Research Achievements

本研究により、これまでは化学合成が困難であったガングリオシドの合成を簡便化し、ガングリオシドの蛍光プローブ開発を実現することができた。この蛍光プローブにより、これまでは機能が不明であり、癌の増殖・浸潤と関連の深いガングリオシドの生細胞上での挙動を初めて明らかにすることができた。本研究は癌の浸潤や増殖の機構の詳細な理解につながることが期待できる。
