Outline of Final Research Achievements |
Using NanoBiT technology, which is a split type of NanoLuciferase (NLuc), the purpose was to construct a biosensor that detects and visualizes the ligand of the peroxisome proliferator-activated receptor γ (PPARγ) with high sensitivity. The LXXLL sequence that interacts with the LBD of PPARγ was comprehensively screened, and the LXXLL sequence was optimized to improve the relative light change amount to a large amount and high light intensity.Finally, the luminescence increased about 30 times in response to the PPARγ ligand Rosiglitazone, and we succeeded in creating a biosensor with high luminescence intensity.

Academic Significance and Societal Importance of the Research Achievements |
ペルオキシソーム増殖因子活性化受容体γ(PPARγ)の合成リガンドは、糖尿病やアルツハイマー病をターゲットに研究が行われており、本バイオセンサーの開発に成功し実用化できれば、PPAR γリガンドの体内動態・脳内移行を長期的に調べることが可能となり、医薬品の副作用の有無を評価するなど、医療面で大きく貢献できると考えられる。今回開発に成功したPPARγバイオセンサーは、PPARγリガンドのスクリーニングにも応用が可能であるため、糖尿病やアルツハイマー病の治療薬の開発にも貢献できると考えられる。
