摘要 哺乳动物细胞高效表达系统是基因工程制药研究中的一个重要内容,而表达载体和宿主细胞是哺乳动物细胞表达系统的2个基本组成部分。近年来通过降低目的基因的位置效应、提高目的基因的转录和翻译水平以及目的基因的拷贝数等方面构建哺乳动物细胞高效表达载体。与此同时,研究者也对宿主细胞进行了多方面的改造,使之能更好地适应工业化大规模培养的要求,从而降低细胞培养和产品纯化的成本。本文就哺乳动物细胞高效表达载体的构建及宿主细胞的改造等方面的最新进展作一简述。 Highly efficient expression of interest genes in mammalian cells is one of the crucial steps for biopharmaceuticals. There are many factors affecting the quality and yield of the recombinant proteins. The main factors includes the expression vectors, the host cell and so on. The latest developments, in optimization of interest gene, vector construction of high-level expression and engineering of host cells, were provided in this review.
