Outline of Research at the Start

マウス扁平上皮癌細胞の転移モデルの腫瘍組織について空間的トランスクリプトーム解析を行うことにより、腫瘍局所において転移を促進する因子としてMIE-1を見出した。腫瘍免疫抑制と転移促進の関連が示唆されたことから、癌細胞からのMIE-1分泌機構ならびにMIE-1による腫瘍免疫抑制の作用機序を解明すると同時に、食道癌患者の腫瘍組織、血液におけるMIE-1の発現量と転移、再発予後との関連を解明する。

Outline of Final Research Achievements

The aim of the study was to clarify the role and significance of Galectin-7, a new regulator of lymph node and lung metastasis found in spatial transcriptome analysis of highly metastatic tumors. Although Galectin-7 expression was elevated in areas of tumor immunosuppression, Galectin-7 had little effect on immune cell activation. Hypoxia also did not affect Galectin-7 expression in cancer cells, but Galectin-7 expression was revealed to be regulated by TNF-a. Furthermore, G-CSF was found to be important for induction of neutrophil infiltration and cell proliferation. Tissue array analysis of human esophageal cancer showed that high G-CSF expression correlated with poor prognosis.

Academic Significance and Societal Importance of the Research Achievements

本研究成果により、Galectin-7の阻害が食道や頭頚部の扁平上皮癌に対する治療に応用できることを世界に先駆けて明らかにした。とりわけGalectin-7の阻害には細胞増殖を抑制する作用がなく転移を特異的に抑えることから、通常の抗がん剤のような副作用の危険性が少ないことが利点であると考えられる。また、本研究で新たにG-CSFが癌細胞の増殖と免疫抑制を促進しがん悪性化に寄与することが分かり、さらに食道癌の予後不良と相関することが明らかになった。Galectin-7とG-CSFの2つの標的を合わせて食道や頭頚部の扁平上皮癌の治療、診断に応用することが期待される。
