由于编码瘦素受体的基因中的基因突变(fa),纯合子Zucker大鼠(fa-/-)发展为过度肥胖,并成为肥胖和代谢相关疾病研究的实验动物模型。基于四引物扩增难治突变系统-聚合酶链反应(ARMS-PCR),我们建立了一种快速分型Zucker大鼠野生型fa等位基因的方法。在2.0%琼脂糖凝胶上,三种基因型可以明显区分。我们的方法可以作为一个可靠的工具,建立和维护繁殖群体的动物设施,以及分配动物的基因型为基础的控制和治疗组的动物研究。
Due to the genetic mutation (fa) in the gene encoding for leptin receptor, homozygous Zucker rats (fa−/−) develop excessive adiposity and become an experimental animal model in obesity and metabolic-related diseases research. Based on tetra-primer amplification refractory mutation system-polymerase chain reaction (ARMS-PCR), we developed a method to quickly genotype Zucker rats with a mutated fa allele from their wildtype littermates. The three genotypes are clearly discriminated on 2.0% agarose gel. Our method can be used as a reliable tool to set up and maintain the breeding colony in animal facilities as well as assign animals to control and treatment groups based on their genotypes for animal studies.
