项目摘要
Four strains of spontaneously hyperlipidemic (SHL) mice: phenotypic distinctions determined by genetic backgrounds.Spontaneously hyperlipidemic(SHL) mice are Japanese wild mice (KOR) with disruption of the apolipoprotein E(Apo E) gene. These mice (KOR-Apoe(shl)) are superhypercholesterolemic and develop severe xanthoma, but their atherosclerosis is relatively mild compared with Apo E knockout mice. First, we tested whether this distinction is due to additional mutation of the Apoc1 and/or Apoc2 genes in KOR-Apoe(shl). Southern blot analysis, but found no gross disruption of these genes. Next, we tested whether the phenotypic distinction is due to differences in the genetic background. To this end, we established three lines of congenic SHL mice with a genetic background of C57BL/6,BALB/c or C3H/He, and named them, respectively, C57BL/6.KOR-Apoe(shl) (B6.KOR-Apoe(shl)), BALB/c.KOR-Apoe(shl) (C.KOR-Apoe(shl)) and C3H/He.KOR-Apoe(shl) (C3.KOR-Apoe(shl)). Hypercholesterolemia was most seve … More re in KOR-Apoe(shl) followed the by others as follows; KOR-Apoe(shl)>>C3.KOR-Apoe(shl)>C.KOR-Apoe(shl)>B6.KOR-Apoe(shl). In contrast, atherosclerosis was most severe in B6.KOR Apoe(shl) followed by the others: B6.KOR-Apoe(shl)>C.KOR-Apoe(shl)>>C3.KOR-Apoe(shl)> or =KOR-Apoe(shl). This order, however, did not match that in xanthoma, which was highly prominent in KOR-Apoe(shl) but mild in B6.KOR-Apoe(shl), C.KOR-Apoe(shl) and C3.KORApoe(shl). This order, however, did not match that in xanthoma, which was highly prominant in KOR-Apoe(shl) but mild in B6.KOR-Apoe(shl), C.KOR-Apoe(shl) and C3.KOR-Apoe(shl). These distinctions suggest that the severity of each of the phenotypes is determined by distinct genetic backgrounds which probably are composed of polymorphism of lipid metabolism-related proteins. We found that apolipoprotein A-I is decreased in each SHL strain and polymorphic between B6.KOR-Apoe(shl) and the other strains examined. This polymorphism may be related to the most severe atherosclerosis observed in B6.KOR-Apoe(shl). It is most likely that combination of such polymorphisms is due to the genetic background accountable for phenotype distinctions. J Atheroscler Thromb.2001;8(3):71-9. Less
四种自发性高脂血症(SHL)小鼠:遗传背景决定的表型差异自发性高脂血症(SHL)小鼠是载脂蛋白E(Apo E)基因被破坏的日本野生小鼠(KOR)。这些小鼠(KOR-Apoe(shl))是超高胆固醇血症的并且发展为严重的黄色瘤,但是与ApoE敲除小鼠相比,它们的动脉粥样硬化相对轻微。首先,我们测试了这种区别是否是由于KOR-Apoe(shl)中Apoc 1和/或Apoc 2基因的额外突变。Southern印迹分析,但没有发现这些基因的严重破坏。接下来,我们测试了表型差异是否是由于遗传背景的差异。为此,我们建立了具有C57 BL/6、BALB/c和C3 H/He遗传背景的3个SHL小鼠品系,分别命名为C57 BL/6.KOR-Apoe(shl)(B6.KOR-Apoe(shl))、BALB/c.KOR-Apoe(shl)(C.KOR-Apoe(shl))和C3 H/He.KOR-Apoe(shl)(C3.KOR-Apoe(shl))。高胆固醇血症最严重 ...更多信息 KOR-Apoe(shl)>>C3.KOR-Apoe(shl)>C. KOR-Apoe(shl)>B6.KOR-Apoe(shl)。相反,动脉粥样硬化在B6. KOR-Apoe(shl)中最严重,其次是其他:B6.KOR-Apoe(shl)>C.KOR-Apoe(shl)>>C3.KOR-Apoe(shl)>或=KOR-Apoe(shl)。然而,这一顺序与黄色瘤中的顺序不一致,黄色瘤在KOR-Apoe(shl)中高度突出,而在B6.KOR-Apoe(shl)、C.KOR-Apoe(shl)和C3. KORApoe(shl)中轻微。然而,这一顺序与黄色瘤中的顺序不一致,黄色瘤在KOR-Apoe(shl)中高度恶性,而在B6.KOR-Apoe(shl)、C.KOR-Apoe(shl)和C3.KOR-Apoe(shl)中轻度恶性。这些区别表明,每个表型的严重程度是由不同的遗传背景,这可能是由脂质代谢相关蛋白的多态性。我们发现载脂蛋白A-I在各SHL株中均降低,并在B6、KOR-Apoe(shl)与其他被检株之间存在多态性。该多态性可能与B6.KOR-Apoe(shl)中观察到的最严重的动脉粥样硬化有关。这是最有可能的,这种多态性的组合是由于遗传背景负责表型的区别。动脉粥样硬化血栓杂志.2001;8(3):71-9.少
