基因修饰技术在生物系统和途径的研究中起着至关重要的作用。尽管基因小鼠模型被广泛和有益地使用,但基因靶向技术存在潜在的缺点,并且并不总是被考虑到。与技术相关的疏忽可能导致对结果的误解;例如,消融感兴趣的基因似乎会导致观察到的表型,而实际上,遗传背景中残留的胚胎干细胞衍生的遗传物质或消融基因周围的区域实际上是负责的。这篇综述的目的是提醒研究人员,无论科学学科,敲除菌株的背景遗传学可以对任何观察到的表型产生深远的影响。在数据收集和解释过程中适当处理这一问题是很重要的。
Gene modification technologies play a vital role in the study of biological systems and pathways. Although there is widespread and beneficial use of genetic mouse models, potential shortcomings of gene targeting technology exist, and are not always taken into consideration. Oversights associated with the technology can lead to misinterpretation of results; for example, ablation of a gene of interest can appear to cause an observed phenotype when, in fact, residual embryonic stem cell-derived genetic material in the genetic background or in the area immediately surrounding the ablated gene is actually responsible. The purpose of this review is to remind researchers, regardless of scientific discipline, that the background genetics of a knockout strain can have a profound influence on any observed phenotype. It is important that this issue be appropriately addressed during data collection and interpretation.
