Because of the significant adverse drug reactions associated with hepatotoxicity, several drugs have been removed from the pharmaceutical market. In most cases, the mechanisms of the hepatotoxicity are unknown and predictive experimental animal models are lacking. Thus, experimental animal models of drug-induced liver injury will enable to perform comprehensive analyses for predictive toxicity studies. The miRNA research in the metabolism of xenobiotics and endobiotics and in toxicology has only recently been established. We performed studies with the following titles,(1) Establishment of halothane-induced liver injury in mice and involvement of miRNA on early onset of liver injury.(2) Involvement of immune-related factors and miRNA in the mouse model of diclofenac-induced liver injury.(3) Establishment of the mouse model of flucloxacillin-induced liver injury.(4) Plasma microRNA profiles in rat models of hepatocellular injury, cholestasis, and steatosis.(5) Peroxisome proliferator-activator receptor. is regulated by miR-21 and miR-27b in human liver

由于与肝毒性相关的显著药物不良反应，几种药物已从医药市场上移除。在大多数情况下，肝毒性的机制是未知的，缺乏预测性的实验动物模型。因此，药物性肝损伤的实验动物模型将能够进行预测毒性研究的综合分析。miRNA在外源性物质和内源性物质代谢以及毒理学中的研究只是最近才建立起来。我们进行了以下研究：（1）建立氟烷诱导的小鼠肝损伤模型及miRNA在早期肝损伤中的作用。(2)免疫相关因子和miRNA在地塞米松诱导的小鼠肝损伤模型中的作用(3)氟氯西林致小鼠肝损伤模型的建立。(4)肝细胞损伤、胆汁淤积和脂肪变性大鼠模型中的血浆microRNA谱。(5)过氧化物酶体增殖物激活物受体。在人肝脏中受miR-21和miR-27 b调控
