项目介绍:

简称:ApoE(动脉粥样硬化小鼠模型)

品系类型:基因敲除

来源:南京大学模式动物研究所

繁殖方式:阳性(T)♂×阳性(T)♀


应用领域:


1. 糖尿病和肥胖研究

2. 神经生物学研究

3. 心血管研究

4. 药效评价


背景介绍:


年老的ApoE基因缺陷小鼠(大于17个月)在脑部晶状胆固醇裂隙,脂质滴和泡沫细胞中有黄瘤的损害,小的黄瘤在脉络丛和腹侧弯中能看到。最近研究表明ApoE缺陷小鼠对应激、减弱的学习与记忆,改变的长期增强效应,突触的损害等都有反应。西方膳食会诱导小鼠产生脂肪纹

Hyperlipidemia and atherosclerosis in double-knockout NOD Apoe −/− Ldlr −/− mice. (A) Kinetics of body weight of NOD Apoe −/− Ldlr −/− and B6 Apoe −/− mice fed a HFD for 20 weeks, with NOD and B6 wild-type controls. For each time point, at least three animals were analyzed for each genotype (n=3-55). (B) Blood cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) concentrations of mice on normal diet for 20 weeks analyzed in two independent experiments involving NOD Apoe −/− Ldlr −/− and NOD control mice (n=8-19). 'in [mmol/L]', the levels of TC, TG, LDL and HDL were measured in mmol/l. (C) Blood TC, TG, HDL and LDL concentrations of mice on a HFD for 20 weeks analyzed in two independent experiments involving NOD Apoe −/− Ldlr −/− and NOD mice (n=4-11). (D) Representative images of Oil-Red-O-stained aortas of mice on a HFD for 4, 8 and 20 weeks (en face assay). (E) Quantitative analysis of en face lesion area of NOD Apoe −/− Ldlr −/− and B6 Apoe −/− mice fed a HFD for 20 weeks, with NOD and B6 wild-type control mice [NOD, n=6 (male=3, female=3); NOD Apoe −/− Ldlr −/− , n=23 (male=10, female=13); B6, n=6 (male=3, female=3); B6 Apoe −/− , n=13 (male=4, female=9)]. Data were collected from two independent experiments with the same animals used in D (n=6-23). (F) Four representative microscopy images of aortic root sections from NOD Apoe −/− Ldlr −/− and B6 Apoe −/− mice placed on a HFD for 20 weeks, with controls of NOD and B6 wild-type mice. Scale bars: 400 μm. (G) Quantitation of plaque area relative to the area of the aortic lumen from F
