Outline of Research at the Start

胃粘膜の下層から分泌される腺粘液は、糖鎖の末端にα1,4結合したN-アセチルグルコサミン(αGlcNAc)を有するユニークな糖蛋白質を含んでいる。最近、我々は胃幽門粘膜において炎症を基盤に胃分化型癌を自然発症するA4gntノックアウト(KO)マウスの解析から、αGlcNAcがMUC1とIL-11を介するがん関連シグナルを抑えることで胃分化型癌の発生を制御している可能性を見出した。本研究ではA4gnt KOマウス並びにヒト胃癌の病理検体を解析対象として、MUC1とIL-11に着目しながらαGlcNAcによる胃分化型癌制御機構の解明を目指す。

Outline of Final Research Achievements

This study investigated the involvement of IL-11 and MUC1 signalings in the regulation of pathogenesis in differentiated-type gastric adenocarcinoma by αGlcNAc. With regard to IL-11 signaling, αGlcNAc bound to the IL-11 receptor (IL-11RA) in wild-type mice and phosphorylation of STAT3 was enhanced in A4gnt KO mice compared to wild-type mice. In addition, αGlcNAc-negative and phosphorylated STAT3-positive cancer cells were observed in 8% of human differentiated-type gastric adenocarcinoma. On the other hand, analysis of A4gnt KO mice did not reveal significant findings suggesting a possible involvement of MUC1. These results combined together indicate that IL-11-mediated inhibition of STAT3 phosphorylation is one of the regulatory mechanisms of pathogenesis in gastric carcinoma.

Academic Significance and Societal Importance of the Research Achievements

本研究により胃腺粘液におけるαGlcNAcの消失はIL-11シグナルの活性化を促進することで分化型胃癌の発生に結びつく可能性が示された。糖鎖による胃癌抑制機構についての知見は未だ乏しいことから、本研究成果は糖鎖病理学分野においての学術学的意義がある。またA4gnt KOマウスの胃分化型癌発生にはSTAT3の活性化が関連することが示唆され、さらにヒト胃分化型癌でも癌細胞におけるαGlcNAc陰性かつリン酸化STAT3陽性例が確認できた。この結果は、分化型胃癌の治療戦略として、IL-11/STAT3経路の阻害が有効である可能性を示している。
