Outline of Final Research Achievements

We have demonstrated for the first time that SnCl2 pretreatment ameliorates RM-AKI induced upon injecting glycerol into the hind limbs of rats. This could be attributed to the early, enhanced, and persistent induction of HO-1 expression by SnCl2 in the kidney as SnCl2 is a kidney-specific inducer of HO-1. We also showed that renal expression of ALAS1 and Bach1 in SnCl2- pretreated animals was maintained almost to the same extent as that in normal animals, while this expression was significantly suppressed in saline-pretreated animals. ALAS1 is downregulated by heme, and Bach1 is exported from the nucleus in complexes that contain increased intracellular heme content. Thus, our findings suggest that overexpression of HO-1, the rate-limiting enzyme in heme catabolism, by SnCl2 pretreatment confers protection against rat RM-AKI as it degrades the excess amount of intracellular free heme, a pro-oxidant released from myoglobin.

Academic Significance and Societal Importance of the Research Achievements

横紋筋融解症に伴う急性腎傷害(RM-AKI)では、筋ミオグロビン由来の遊離ヘムがその病態形成に関わっていることが報告されている。塩化スズは腎特異的に、ヘム代謝の律速酵素であるHO-1を誘導する薬剤である。
グリセロール筋肉注射による RM-AKI ラットモデルを用い、塩化スズによる腎保護作用と症機序を、その作解明することは、災害現場でも利用可能なRM-AKIに対する治療法の開発につながり、さらには早期治療開始により腎傷害の重症化予防、救命率の向上などに大いに貢献できると考える。
本研究は、塩化スズ による RM-AKI の治療法の開発を進める上で重要な基礎研究と考える。
