摘要

近交系小鼠长期以来一直被证明是生物医学研究的有用工具。它们消除了遗传背景作为实验变量的影响。在所有小鼠群体中,遗传漂变是一种公认的现象,监测和记录变化对于实验设计和一致性非常重要。这篇通讯记录了医学研究理事会国家医学研究所(MRC-NIMR)米尔希尔分所(现为克里克研究所)当时培育和使用的近交系小鼠品系的 SNP 分析的初步特征。这些近亲繁殖品系是米尔希尔制造的许多转基因小鼠品系的基础群的一部分。我们在九个近交系中的四个中发现了微小的基因变化。虽然尚未发现 NIMR 和相应亲本品系之间的表型差异,但我不能排除这些差异可能会出现或已经出现。这项工作还鉴定了在 MRC-NIMR 广泛用于基因打靶的 129/SvJEvNimr-Gpi1c 品系。所有这些近交系都已根据国际小鼠标准化遗传命名委员会(The International Committee on Standardized Genetic Nomenclature for Mice)重新命名。

Single nucleotide polymorphism (SNP) characterisation of mouse inbred strains bred at MRC-National Institute for Medical Research.

Inbred mouse strains have long proved useful as tools for biomedical research. They remove the effects of genetic background as an experimental variable. Within all mouse colonies, genetic drift is a recognised phenomenon and monitoring and documenting changes is important for experimental design and consistency. This communication documents the initial characterisation through SNP analysis of the inbred mouse strains bred and used at the time at the Medical Research Council National Institute for Medical Research (MRC-NIMR), Mill Hill, now The Crick Institute. These inbred strains were part of the foundation colonies for the many genetically modified mouse strains made at Mill Hill. We found small genetic changes in four of the nine inbred strains. Although phenotypic differences have not yet been found between the NIMR and the correspondent parental strains, I cannot discard that these may arise or have already arisen. This work has also authenticated the 129/SvJEvNimr-Gpi1c strain that was widely used at MRC-NIMR for gene targeting. All these inbred strains have been renamed according to The International Committee on Standardized Genetic Nomenclature for Mice.

期刊介绍: The international journal of laboratory animal science and welfare, Laboratory Animals publishes peer-reviewed original papers and reviews on all aspects of the use of animals in biomedical research. The journal promotes improvements in the welfare or well-being of the animals used, it particularly focuses on research that reduces the number of animals used or which replaces animal models with in vitro alternatives.
