Outline of Research at the Start

腎臓病は、透析治療を必要とする腎不全の原因となる大きな問題である。腎臓病の鍵をにぎるのは、タコ足細胞の傷害である。タコ足細胞は、腎全体の1%足らずの少数ではあるが、文字通りタコのように突起を伸ばし、尿に蛋白を漏らさない働きをしている。本研究では、マウスのタコ足細胞に効率よく簡便に遺伝子を変異させる方法を開発し、変異により傷害を軽くする遺伝子を探す事をめざしている。将来的にこの研究は、タコ足細胞の治療薬の開発へとつながる事が期待される。

Outline of Final Research Achievements

Gene expression pattern is dynamically changed in kidney diseases. To study gene functions in kidney diseases, we aimed to develop a simple method to modify a specific gene in a mouse body with kidney disease. We generated mice in which the kidney expresses a gene-modifying enzyme and tried to develop a carrier protein that delivers guide RNA to kidney cells. The carrier protein is taken up into kidney cells, however further improvement is necessary to accomplish this project.

Academic Significance and Societal Importance of the Research Achievements

期間内に達成できなかったが、核酸を特定の細胞に送り込む技術は、医学生物学研究を加速させる基盤技術となるし、治療薬としての利用が注目されている核酸の腎臓への送達技術は、臨床的にも重要である。今研究で明らかになった技術的問題の解決が望まれる。
