复杂性状遗传CC小鼠与精准医学研究

生物组学技术在生物学、医学上的转化应用,为精准的个体化预防、诊断、治疗提供了关键性的技术体系,精准医学模式应运而生。实验动物学研究是疾病发病机制研究转化到临床不可或缺的手段。为应对目前严重危害人类疾病的复杂性、多样性特点,2002年国际复杂性状联盟(Complex Trait Consortium,CTC)倡议研发建立新的小鼠遗传资源库;通过不同纯系小鼠品系间的杂交创建小鼠复杂性状遗传资源库(Collaborative Cross mice,CC小鼠)。随着原始亲本小鼠(founder)选定、杂交品系的繁殖,CC小鼠在检测小鼠表型、疾病易感性、疾病发生发展及预后与遗传因素的关系方面进行了系列的尝试。文中将就CC小鼠在疾病发生发展及药物评价个体化研究中的应用做一简要介绍。

Collaborative Cross mice and precision medicine

The individual variability should be considered in precision medicine-prevention and treatment strategies. Medical research using genomics, proteomics, metabolomics, systems analyses, and other modern tools has made big progress.In 2002, the members of the Complex-Trait Consortium proposed to develop a new mouse genetics resource called the Collaborative Cross (CC). The CC is a genetic reference panel of recombinant inbred lines of mice, designed for the dissection of complex traits and gene networks.It will provide a powerful measure for functional studies of biological networks, which will be essential to understand the intricacies of disease processes.
