本文主要研究内容
作者郭超婧,朱琼,张新,李磊,张令强(2019)在《去泛素化酶OTUB1肝脏特异性基因敲除小鼠模型的构建与表型分析》一文中研究指出:目的:建立OTUB1肝脏特异性基因敲除小鼠模型,初步分析其表型并研究OTUB1基因与肝脏代谢的关系。方法:利用Cre/Loxp系统构建条件性基因敲除小鼠模型,即将OTUB1fl/fl转基因小鼠与Alb-Cre小鼠杂交,子代自交,得到OTUB1肝特异性基因敲除小鼠并进行鉴定。取同窝对照小鼠(control,NC)和肝特异型基因敲除(hepatic-specific OTUB1 knockout,HCKO)小鼠,通过PCR和免疫印迹(Western blot),确证OTUB1肝脏特异性基因敲除小鼠模型是否成功构建。通过组织病理学方法,分析主要组织器官的形态以及是否存在自发的病变;通过血清生化指标检测肝脏脂代谢水平;通过血糖耐受实验(GTT)分析HCKO小鼠对血糖的控制。结果:基因组测序和Western blot检测结果显示HCKO小鼠肝脏中OTUB1被敲除,其他组织中OTUB1表达水平无变化,证明OTUB1肝脏特异性基因敲除小鼠模型构建成功。HCKO小鼠出生正常,各组织器官无异常,生化指标中总胆固醇水平明显降低,表明OTUB1影响肝脏脂代谢水平。糖耐受实验中HCKO小鼠血糖回落迅速,表明敲除OTUB1影响肝脏血糖调节稳态。结论:应用Cre/Loxp技术成功建立OTUB1肝脏特异性基因敲除小鼠模型,为研究OTUB1在肝脏的生理功能和调控机制提供了重要的动物模型。
