Outline of Final Research Achievements |
The present study investigated the change in susceptibility to acetaminophen-induced liver injury in a murine model of nonalcoholic fatty liver disease (NAFLD; DIO-NTac mouse), developing diet-induced fatty liver with obesity and altered glucose tolerance. Liver injury induced by an acetaminophen administration was reduced in DIO-NTac mice compered with control mice, suggesting a decreased susceptibility to acetaminophen hepatotoxicity in this mouse model. The decreased susceptibility was shown to be associated with alteration of xenobiotic enzymes by fatty liver.

Academic Significance and Societal Importance of the Research Achievements |
本研究では,近年問題視される非アルコール性脂肪性肝疾患(NAFLD)に合併する薬剤性肝傷害のメカニズム解明を試みた。国内のNAFLD患者は成人の20~30%と考えられており,また患者の多くは医薬品を継続的に服用する必要があることから,本研究で得られたデータが,NAFLD患者に対する治療や医薬品開発の一助となることが期待される。
