Argonautes(Agos)是RNA沉默的核心效应子。在一些非哺乳动物生物体中,已知多种Ago对不同的RNA沉默途径表现出专门的功能。哺乳动物有四个密切相关的Ago。为了检查哺乳动物Agos在microRNA沉默途径中的功能,我们产生了对所有Agos都是无效合的小鼠胚胎干(ES)细胞。本章介绍了各种技术,包括BAC重组工程,基因打靶,和诱导Cre-loxP重组,用于产生诱导型Ago基因敲除ES细胞。Ago缺陷的ES细胞为哺乳动物RNA沉默的研究提供了重要的工具。
Argonautes (Agos) are core effectors of RNA silencing. In several nonmammalian organisms, multiple Agos are known to exhibit specialized functions for distinct RNA silencing pathway. Mammals have four closely related Agos. To examine the functions of mammalian Agos in the microRNA silencing pathway, we generated mouse embryonic stem (ES) cells that are nullizygous for all Agos. This chapter describes a variety of techniques including BAC recombineering, gene targeting, and inducible Cre-loxP recombination, used to generate inducible Ago knock-out ES cells. The Ago-deficient ES cells provide an important tool for the study of mammalian RNA silencing.
