Outline of Final Research Achievements

Focusing on the diversity in aging exhibited by fish, we searched for various genes that may be associated with longer and shorter life spans based on genome analysis. We identified a group of transcription factors associated with the anti-aging properties of fish muscle, and compared them with those of mammals, and showed that the function of these genes may contribute to the unique lifetime muscle growth of fish. In addition, we showed that the post-breeding mortality of ayu, a short-lived species, is similar to that of mammals, indicating that this species has high potential as a new model for aging analysis. Furthermore, the genome of the Greenland shark, which has been reported to be nearly 400 years old, was clarified for the first time, and the characteristics of life span-related genes were elucidated.These results provide important and unique insights into the genetic basis of the diverse aging and lifespan characteristics of vertebrates.

Academic Significance and Societal Importance of the Research Achievements

魚類の示す老化や寿命の多様性は脊椎動物の寿命や老化を理解する上で興味深いが、これまで魚自身の老化や寿命特性に着目した研究は少なかった。本申請課題では、魚の抗老化特性を解析すると共に、短命魚や長命魚のゲノム解析から、寿命の長短に関連する可能性のある様々な遺伝子を探索した。特に400歳近い個体が報告されるニシオンデンザメのゲノムは初の報告となる。本研究で得られた成果は、脊椎動物の多様な老化・寿命特性の遺伝的基盤を理解する上で重要かつ極めてユニークな知見を提示し、今後の老化・寿命研究に資するものである。
