J Hepatol:饮食和化学诱导的小鼠NASH模型,可快速发展为脂肪性肝炎,纤维化和肝癌

2018-07-24 MedSci MedSci原创

新的小鼠NASH模型在短期内疾病可迅速进展为晚期纤维化和HCC,并模拟了人类NASH的组织学、免疫学和转录特征,这表明它将是临床前药物测试的一个有用的实验工具。

研究背景:虽然大多数非酒精性脂肪肝(NAFLD)患者仅存在无进展性脂肪变性,但相当一部分患者可发展为非酒精性脂肪性肝炎(NASH),最终导致肝硬化和肝细胞癌(HCC)。目前已建立的NASH模型,需要花费24-52周的时间,这使得药物反应的检测变得昂贵且耗时。

研究方法:本研究通过采用高脂肪、高果糖、高胆固醇的西方饮食(WD),结合低剂量每周一次的腹腔注射四氯化碳(CCl4)来建立小鼠NASH模型。此模型可以快速发展为广泛性纤维化和肝细胞癌(HCC)。

研究结果:C57BL/6J小鼠接受12周或24周的正常饮食±CCl4或WD±CCl4。CCl4的加入加重了WD诱导的NASH、纤维化和肿瘤的组织学特征,导致12周形成3期纤维化,24周HCC的发生。此外,全肝脏转录分析显示,WD/CCl4小鼠的分子通路异常,免疫功能与人类NASH相似。

研究结论:新的小鼠NASH模型在短期内疾病可迅速进展为晚期纤维化和HCC,并模拟了人类NASH的组织学、免疫学和转录特征,这表明它将是临床前药物测试的一个有用的实验工具。
