Outline of Final Research Achievements

We have showed that zinc transporter ZIP7 is critical for intestinal homeostasis by maintaining intestinal epithelial stem cells and progenitor cells. Our investigations focus on the role ZIP7 in the pathogenesis of colorectal cancer. We showed that knockdown of ZIP7 by siRNA or shRNA significantly suppressed cell growth by causing apoptosis and ameliorate tumor growth in vivo. In addition, we demonstrated that increased ZIP7 expression enhanced tumorigenic potential. Our data reveal an important role of ZIP7 in colorectal tumorigenesis, which can contribute to novel therapy for colorectal cancer.

Academic Significance and Societal Importance of the Research Achievements

亜鉛トランスポーターが種々の生体の正常な機能の発揮に関わっていることが明らかとなり、亜鉛トランスポーターの機能の異常はどのような疾患に関わり、また、その疾患の発症や増悪においてはどのような役割を持っているのかについて注目が集まっている。大腸がん発症進展機構における種々の要因の解明に基づいた大腸の悪性腫瘍の病態概念理解への貢献が本研究成果の学術的・社会的意義である。
