长爪沙鼠NAFLD模型的建立及其遗传学的研究

非酒精性脂肪性肝病(NAFLD)已成为目前主要代谢性疾病之一,针对传统的动物模型的缺陷,本研究首次建立了与人类NAFLD(从单纯脂肪肝到脂肪性肝炎,再进展到肝纤维化、肝硬化)极为相似、饲料配方简便的长爪沙鼠NAFLD模型,阐明了长爪沙鼠肝脏脂肪快速沉积的特征,揭示长爪沙鼠脂肪肝易感的分子机制、主要的调控靶点和网络作用特征,为临床治疗及新药研发提供一种背景相对清晰,耗时短的新型脂肪肝动物模型,同时也为NAFLD发病机制及药效新靶点的研究提供实验动物支撑,为选育近交系NAFLD长爪沙鼠奠定了理论与实践基础。

Preliminarily genetic characterizations of nonalcoholic fatty liver disease mongolian gerbil

Non-alcoholic fatty liver disease (NAFLD) has become one of the major metabolic diseases. In view of the defects of traditional animal models, this study was the first to establish the NAFLD model of Mongolian gerbil (Meriones unguiculatus) with simple feed formula which is similar to human (from simple fatty liver to steatohepatitis, fibrosis,Liver cirrhosis). This study discussed the mechanism of rapid fatty liver deposition in Mongolian gerbil, revealed its molecular mechanism,main regulatory target and network function of fatty liver susceptibility. We provide a new animal model of NAFLD with relatively clear background and less time-consuming for clinical treatment and new drug development. The theoretical and practical basis for the breeding of inbred strain NAFLD gerbil was established.
