ATP 8B 1(FIC 1)突变是胆汁淤积性疾病的基础,从慢性和进行性(进行性家族性肝内胆汁淤积)到间歇性(良性复发性肝内胆汁淤积)。ATP 8B 1缺陷型小鼠作为人类ATP 8B 1缺陷的动物模型。我们使用C57 B1/6(B6)、129和(B6-129)F1品系背景研究了遗传背景对ATP 8B 1缺陷型和野生型小鼠表型的影响。B6背景导致ATP 8B 1缺陷小鼠比129和/或F1背景更大的异常。B6背景的ATP 8B 1缺陷幼仔体重增加较少。在基线时的成年ATP 8B 1缺陷小鼠中,B6背景小鼠的血清胆固醇水平较低,血清碱性磷酸酶水平较高,肝脏较大。用补充胆酸盐的饮食激发后,这些小鼠表现出较高的血清碱性磷酸酶和胆红素水平,体重减轻更大,肝脏更大。在F1和129背景的小鼠中,ATP 8B 1缺陷表型通常相似,表明对ATP 8B 1缺陷表现的易感性可能是隐性的。我们还检测到不同品系野生型小鼠之间肝胆表型的差异。我们的研究结果表明,在B6背景下的ATP 8B 1缺陷小鼠可能是人类ATP 8B 1缺陷的更好模型,并强调了知情的背景品系选择肝脏疾病小鼠模型的重要性。
Mutations in ATP8B1 (FIC1) underlie cases of cholestatic disease, ranging from chronic and progressive (progressive familial intrahepatic cholestasis) to intermittent (benign recurrent intrahepatic cholestasis). The ATP8B1-deficient mouse serves as an animal model of human ATP8B1 deficiency. We investigated the effect of genetic background on phenotypes of ATP8B1-deficient and wild-type mice, using C57Bl/6 (B6), 129, and (B6-129) F1 strain backgrounds. B6 background resulted in greater abnormalities in ATP8B1-deficient mice than did 129 and/or F1 background. ATP8B1-deficient pups of B6 background gained less weight. In adult ATP8B1-deficient mice at baseline, those of B6 background had lower serum cholesterol levels, higher serum alkaline phosphatase levels, and larger livers. After challenge with cholate-supplemented diet, these mice exhibited higher serum alkaline phosphatase and bilirubin levels, greater weight loss and larger livers. ATP8B1-deficient phenotypes in mice of F1 and 129 backgrounds are usually similar, suggesting that susceptibility to manifestations of ATP8B1 deficiency may be recessive. We also detected differences in hepatobiliary phenotypes between wild-type mice of differing strains. Our results indicate that the ATP8B1-deficient mouse in a B6 background may be a better model of human ATP8B1 deficiency and highlight the importance of informed background strain selection for mouse models of liver disease.
