本研究通过AKR/J和C57 L/J小鼠的互交试验,分析了肥胖的遗传规律。采用选择性DNA池策略,筛选出两个新的肥胖数量性状基因座(QTL)。一个影响肥胖的QTL Obq 3被定位在第2号染色体中部附近的一个39 cM片段上,峰值lod值(5.1)正好位于D2 Mit 15位点的远端。AKR/JObq 3等位基因以几乎累加的方式赋予肥胖增加,并且男性比女性受影响更大。第二个肥胖QTL(Obq 4)定位于染色体17的着丝粒末端,在D17 Mit 143位点,Lod值最高,为4.6。肥胖基因由C57 L/J贡献,以隐性或加性方式作用。Obq 4对男性的影响也较大,对腹股沟脂肪的影响也有差异。Obq 3和Obq 4分别解释了肥胖表型变异的7.0%和6.1(性别合并数据)。这些QTL和以前描述的肥胖QTL和候选基因之间的可能关系进行了讨论。在小鼠中描述的大量不同的肥胖QTL和单个基因座贡献的相对较小的影响表明相当大的遗传复杂性。
The inheritance of obesity has been analyzed in an intercross between the mouse strains AKR/J and C57L/J. Two novel obesity quantitative trait loci (QTLs) have been identified using the strategy of selective DNA pooling. One QTL affecting adiposity,Obq3,was mapped to a 39-cM segment near the middle of Chromosome 2, with a peak lod score (5.1) just distal to theD2Mit15locus. The AKR/JObq3allele confers increased adiposity in a nearly additive manner, and males are more affected than females. A second obesity QTL (Obq4) maps to the centromeric end of Chromosome 17, with a lod score peak of 4.6 atD17Mit143.The obesity-conferring allele is contributed by C57L/J and acts in a recessive or an additive manner.Obq4also has more influence in males and affects the inguinal fat depot differentially.Obq3andObq4account for 7.0 and 6.1% of the phenotypic variance in adiposity (gender-merged data), respectively. The possible relationships between these QTLs and previously described obesity QTLs and candidate genes are discussed. The large number of different obesity QTLs that have been described in mice and the relatively small effects contributed by individual loci suggest considerable genetic complexity.
