Outline of Final Research Achievements

Sialyl-Tn antigen, which is synthesized by a glycosyltransferase ST6GalNAc-I and abnormally expressed in malignant types of cancers. To elucidate whether sialyl-Tn antigen contribute to metabolic reprogramming, we performed metabolome analysis using capillary electrophoresis mass spectrometry (CE-MS). Sialyl-Tn antigen induced pentose phosphate pathway and nucleotide synthesis in H157 cells. Sialyl-Tn antigen expressed on H157 cells also induced the production of oncometabolite, 2-hydroxyglutarate, but did not affects genome-wide alterations in DNA methylation. These findings indicate that sialyl-Tn antigen may be a key player of metabolic reprogramming in the processes of tumor progression.

Academic Significance and Societal Importance of the Research Achievements

これまで、がん糖鎖は腫瘍マーカーとして役割のみ捉えられていた。しかしながら、sialyl-Tn糖鎖抗原は、腫瘍マーカーとしての役割だけではなく、がん転移や酸化ストレスへの耐性への機能、さらに未だ不明な点が多いがん細胞内の代謝改変に関わる機能分子であることがわかった。このようながん細胞の代謝改変に影響を与える糖鎖はこれまで報告がなく、この研究成果の学術的意義は非常に高いと考える。
