该方案描述了使用n -乙基-n -亚硝基脲(ENU)对雄性小鼠进行化学诱变,这是在表型驱动筛选中获得小鼠突变的最有效方法。分剂量的烷基化剂ENU可在雄性小鼠精原干细胞中产生高达1.5 × 10(-3)的突变率。ENU治疗产生的点突变提供了独特的突变资源:它们反映了独立于位置效应的单个基因变化的后果,提供了蛋白质功能的精细结构解剖,展示了从完全或部分功能丧失到功能夸大的一系列突变效应,并以公正的方式发现基因功能。用ENU治疗后,小鼠在基因筛选中进行交配,以发现感兴趣的突变。可以进行显性、隐性和修饰性突变的筛选。
INTRODUCTIONThis protocol describes chemical mutagenesis of male mice using N-ethyl-N-nitrosourea (ENU), which is the most efficient method for obtaining mouse mutations in phenotype-driven screens. A fractionated dose of ENU, an alkylating agent, can produce a mutation rate as high as 1.5 × 10(-3) in male mouse spermatogonial stem cells. Treatment with ENU produces point mutations that provide a unique mutant resource: They reflect the consequences of single gene changes independent of position effects, provide a fine structure dissection of protein function, display a range of mutant effects from complete or partial loss of function to exaggerated function, and discover gene functions in an unbiased manner. After treatment with ENU, mice are mated in genetic screens designed to uncover mutations of interest. Screens for dominant, recessive, and modifying mutations can be performed.
