摘要: 目的 构建和鉴定单核细胞过氧化物酶体增殖物激活受体γ(PPARγ)条件性基因敲除小鼠。方法 将引进的纯合子PPARγ-loxp小鼠和单核细胞特异性表达cre重组酶的Cx3cr1cre小鼠进行杂交,得到F1代,用RT-PCR方法鉴定其基因型。将F1代进行自交产生F2代,鉴定基因型,筛选实验所需的PPARγ条件性基因敲除小鼠(实验组, PPARγ-ko)及对照组小鼠(对照组, PPARγ-wt),利用免疫荧光及Western blotting方法鉴定敲除效果。结果 筛选出基因型为PPARγ loxp/loxp Cx3cr1cre/- 和PPARγ loxp/loxp Cx3cr1cre/cre的小鼠即为本实验所要构建的单核细胞PPARγ条件基因敲除小鼠,基因型为PPARγ loxp/loxp Cx3cr1-/- 小鼠为实验对照组小鼠。结论 成功获得单核细胞PPARγ条件性基因敲除小鼠,为单核细胞上PPARγ功能的研究提供小鼠模型。

Abstract: Objective To generate monocyte- peroxisome proliferator-activated receptor γ(PPARγ) conditional knockout mice and to identify the genotype.Methods The imported PPARγ-loxp mice and CX3CR1-Cre mice were hybridized to generate F1 generation,and the genotypes were identified by RT-PCR.Using the same method to generate F2 generation and detect their genotypes.Then the effect of PPARγgene knock-out were identified by using immunofluorescence and Western blotting.Result The monocyte-PPARγknockout mice (PPARγloxp/loxp Cx3cr1cre/- or PPARγloxp/loxp Cx3cr1cre/cre) were as test group(PPARγko),and the control group(PPARγwt) of mice (PPARγloxp/loxp Cx3cr1-/-) were also identified.Conclusion Successfully established the monocyte-PPARγknock-out mice,and provide a experimental tool to further study the funtions of PPARγon monocyte .
