  Paternal-maternal effects on phenotypic characteristics in spontaneously diabetic Nagoya-Shibata-Yasuda mice

  摘要：

  The Nagoya-Shibata-Yasuda (NSY) mouse is an inbred strain with spontaneous development of type 2 (non-insulin-dependent) diabetes mellitus. The purpose of this study was to determine the mode of inheritance of various phenotypes related to diabetes in this strain. Two reciprocal outcrosses, female C3H/He x male NSY F1 (C3NF1) and female NSY x male C3H/He F1 (NC3F1) mice, were performed. The phenotypic characteristics in both F1 mice were investigated. The cumulative incidence of diabetes was 100% (25 of 25) in male C3NF1 mice and 97% (29 of 30) in male NC3F1 mice at 48 weeks of age, indicating that diabetes in NSY mice was transmitted to male Fl hybrids in an autosomal dominant manner. Fatty liver also showed an autosomal dominant mode of inheritance. In contrast, epididymal fat accumulation and impaired insulin secretion showed an autosomal recessive mode of inheritance. The body mass index (BMI) showed a codominant mode of inheritance. Paternal-maternal effects associated with the severity of diabetes were observed. Insulin resistance was much more severe in male F1 mice than in the parental NSY strain. These data indicate different modes of inheritance among phenotypes related to type 2 diabetes. The presence of more severe insulin resistance in F1 mice versus the parental strains suggests the interaction of both parental genomes in the development of insulin resistance. The F1 mouse is expected to be useful for studies of the pathogenesis and genetic synergism of the insulin resistance syndrome. Copyright (C) 2000 by W.B. Saunders Company.

  these reactions. Enhanced preference for the more sterically demanding Michael adducts is obtained with Bu(2)Sn(OTf)(2), SnCl(4), and Et(3)SiClO(4) in the former reaction while TiCl(4) gives the highest selectivity for the less sterically demanding products in the latter case. These results are interpreted in terms of alternative reaction mechanisms. The reaction of less bulky ketene silyl acetals are

  讨论了乙烯酮甲硅烷基缩醛的Mukaiyama-Michael反应机理。使用各种类型的乙烯酮甲硅烷基乙缩醛的竞争反应表明，那些在β位置带有更多取代基的反应优先于取代较少的取代基。然而，当乙烯酮甲硅烷基乙缩醛涉及庞大的甲硅烷氧基和/或烷氧基时，较少取代的化合物优先反应。路易斯酸在这些反应中起重要作用。在前一个反应中，Bu（2）Sn（OTf）（2），SnCl（4）和Et（3）SiClO（4）获得了对空间要求更高的迈克尔加合物的增强的偏好，而TiCl（4）给出的最高在后一种情况下，对空间要求较低的产品具有较高的选择性。这些结果是根据其他反应机理来解释的。体积较小的乙烯酮甲硅烷基缩醛的反应是通过电子从这些化合物转移到路易斯酸而引发的。另一方面，较大的乙烯酮甲硅烷基缩醛会发生普遍存在的亲核反应。基于各种实验结果以及半经验PM3 MO计算，讨论了这种机械变化。
