多元自动化基因组工程

Multiplex Automated Genome Engineering

基因组编辑技术在基因组工程研究中应用广泛,其中位点特异性核酸酶编辑技术和CRISPR/Cas系统在单基因编辑方面贡献卓越,但由于基因组的庞大,这些技术又有一定的局限性。多元自动化基因组工程(MAGE)是一种新型基因组编辑技术,可同时作用于多个基因,具有快速、高效的特点,已被用于大肠杆菌的基因敲除和基因替换。主要介绍了MAGE的原理、具体操作流程及技术进展,并结合MAGE技术的应用,讨论其发展趋势。

Genome editing is widely used in genome engineering research and site-specific nuclease technologies and CRISPR/Cas system focus on single gene editing. Owing to the huge size of genome, there are some limitations on the applications of these technologies. Multiplex Automated Genome Engineering（MAGE）is a new, fast and efficient genome editing technology, which can operate multiple genes simultaneously, and be used in knockout and replacement ofEscherichia coligenes. This review illustrates the recent advances in the theory, operation protocol and technological innovation of MAGE, its application and development trend were also discussed.
