Outline of Final Research Achievements

Three studies were conducted. 1) Preparation of hypospadias model rat: The time of fetal urethral formation was identified by administering anti-androgen drug to pregnant rats. 2) Gene analysis of fetal penis: Total RNA was extracted from the fetal penis during urethral formation and subjected to cDNA microarray analysis. A novel gene (Pip: Prolactin-induced protein) was identified as an important gene for urethral formation. 3) Pathway analysis: Pathway analysis was performed on the microarray results. As a result, it was revealed that upstream regulatory factors such as FGF enhance the signal pathways of G protein and tyrosine kinase type receptors.

Academic Significance and Societal Importance of the Research Achievements

先天異常の研究において、ヒトを対象とした研究を行うことには限界があり、モデル動物が必要となる。私たちの開発した尿道下裂モデルラットは「遠位型」・「中間位型」・「近位型」と分けることができ、ヒトの臨床病態と極めて類似している。これらをマイクロアレイで網羅的解析をすることにより候補遺伝子を探索し、さまざまなタイプの尿道下裂における遺伝子発現局在を確認できるため、尿道下裂の病態解明に役立つと考えられる。さらに、遺伝子導入技術を用いれば新規治療法への発展も可能である。
