Project Period (FY) 2019-08-30 – 2021-03-31
Keywords尿酸 / トランスポーター / 遺伝子欠損マウス / CRISPR-Cas9 / 痛風 / 生活習慣病 / GLUT12/SLC2A12
Outline of Final Research Achievements

In this study, the physiological function of novel urate transporter GLUT12 was investigated. For this purpose, Glut12 knockout mice were developed and urate levels were compared with wild type mice. As a result, plasma urate levels of Glut12 knockout mice were higher than those in wild type mice. This study provides insights into the deeper understanding of the urate regulatory system in the body, which is also important for pathophysiology of gout/hyperuricemia.

Academic Significance and Societal Importance of the Research Achievements

高尿酸血症は痛風の危険因子となる一方、尿酸は抗酸化作用を有する化合物であり、適切な血中尿酸濃度を維持することは臨床上重要である。細胞膜を介した尿酸の輸送には輸送体の関与が必要であるものの、尿酸輸送体に関する理解は不十分であるのが現状である。本研究により生理的に重要な尿酸輸送体としてGLUT12が見出されたことは、尿酸の体内動態制御機構の理解という学術的興味のみならず、高尿酸血症や痛風の病態形成の理解といった臨床的観点での貢献も期待される。
