Outline of Research at the Start |
Wnt/β-cateninシグナル伝達経路の異常は、細胞の生存や幹細胞の増殖と分化の調節、がん免疫回避機構などに関わる遺伝子の発現を増加させることで、がんの発生や進展に深く関わっている。本研究は、新たなWnt標的遺伝子の機能解析やRNAメチル化修飾解析を通じて、Wntシグナルのさらなる理解に役立てることを目的としている。本研究の成果は、Wntシグナルの異常を持つ腫瘍細胞の性質を分子レベルで理解し、新たな診断・治療法開発のための基盤的情報となることが期待される。

Outline of Final Research Achievements |
The Wnt/β-catenin signaling pathway has been shown to be activated in various types of cancer including colon and liver cancer. In this study, we identified two novel target genes of this pathway, MOSPD1 (motile sperm domain containing 1) and ODAM (odontogenic, ameloblast associated), in colorectal and liver cancer, respectively. In addition, we found their Wnt-dependent enhancers in the 3’-flanking region and 15 kb-upstream region of MOSPD1 and ODAM, respectively. This study also disclosed that ODAM regulates cell cycle progression and proliferation of hepatoma cells. Besides, we identified another target gene, VSNL1 (visinin-like 1) using the near-haploid human cell line HAP1, and showed that VSNL1 plays a crucial role in the anti-apoptotic property of colorectal cancer cells. Further investigation of the biological role of these molecules will contribute to the profound understanding of physiological and pathological processes played by the Wnt signaling pathway.

Academic Significance and Societal Importance of the Research Achievements |
Wnt/β-cateninシグナル伝達経路の異常な活性化は、様々ながん種の発がんや細胞の生存、幹細胞の増殖と分化の調節、最近ではがん免疫回避機構に関与することが報告されている。そのため同経路は、がんの再発や薬剤耐性化の解決に繋がる有望な標的として治療薬開発が行われてきた。しかしながら、実際の臨床で投与可能な治療薬の開発には至っていないのが現状である。我々の研究成果は、Wntシグナルの多種多様な生物学的プロセスの理解に役立つだけでなく、これら下流分子を標的とする新しい抗がん剤開発への展開が期待される。
