Outline of Research at the Start

悪性中皮腫における分子診断や分子標的療法への応用としてmiRNAを含めた種々の分子が検討されてきているが、実用化されている分子は未だに存在していない。我々は悪性中皮腫の増殖に関与することが示されたHEG1の発現に関与するmiRNAを見出し、標的候補分子の発現も含めて悪性中皮腫の性質について明らかにしつつある。本研究はこれらを踏まえ、癌細胞の変化に応じたmiRNA及び標的分子を見出し、客観的に分子診断をすること、さらには分子機能を明らかにし、創薬を目指した標的候補分子を見出すことを目指す。

Outline of Final Research Achievements

The molecular target of malignant mesothelioma (MM) has not been elucidated because of unknown survival, death, and cytotoxic signals in MM. HEG homolog 1 (HEG1) is a mucin-like membrane protein that contains epidermal growth factor-like domains, and HEG1 expression supports the survival and proliferation of MM cells. In this study, functional analysis of HEG1 and microRNAs using MM cell lines was performed. MiR-23b contributes to HEG1-dependent cell proliferation through evasion of cytotoxicity induced by apoptosis and autophagy in MM cells. HEG1-dependent/mediated miR-23b signaling may therefore be a potential target for MM diagnosis and therapy.

Academic Significance and Societal Importance of the Research Achievements

悪性中皮腫におけるHEG1の位置付けを明らかにすることで病理組織診断および予後との関連性が明らかになる。また、HEG1およびmiRNAとその標的候補分子による早期診断と予後予測、さらには分子標的治療に役立つ。
