Outline of Final Research Achievements |
In this study, genomic factors involved in hepatocarcinogenesis were investigated. We analyzed HCC samples obtained by hepatic resection using a semiconductor sequencer, and clarified the differences in genomic factors among different viral conditions. Based on these findings, genetically mimicked human iPS cells were constructed, and analyzed their phenotype to elucidate the mechanism responsible for hepatocarcinogenesis.

Academic Significance and Societal Importance of the Research Achievements |
本研究ではHCV排除後やHBV持続感染、及び非ウイルス性肝癌に関わる癌ゲノムプロファイルを明らかとし、ヒトiPS細胞培養技術および遺伝子改変技術を応用した病態解析モデルを開発し、発癌・病態形成機構の解明を進めた。本研究により、未だ根本治療や予防法の存在しない肝癌における、これまでとは視点を異にする新規治療法開発への展開が期待されるとともに、これらの研究手法は他分野に広く応用可能である。
