    摘要: The present invention relates to improved retroviral vectors for gene therapy. In this invention, retroviral vectors with higher safety and efficiency are constructed from MLV-based starting vectors, MON and MIN. The improved vectors have the following features: 1) sequences corresponding to MLV-derived pol gene are completely deleted in the vectors, avoiding homologous recombination which has been a baffling problem in conventional retroviral vectors, 2) a heterologous intron, splicing acceptor and/or non-coding sequence are/is inserted into the upstream position of a cloning site, maximizing the expression of a foreign gene through efficient splicing, 3) the vectors contain either the full-length U3 sequence of 5′ LTR or a strong heterologous promoter instead, permitting the abundant production of RNA, 4) either IRES (Internal Ribosomal Entry Site) or internal SV40 minimal promoter is inserted into the downstream position of cloning site, enabling the simultaneous expression of two or more foreign genes. Since the improved retroviral vectors of this invention turn out to be safe and to express the foreign gene efficiently, they are useful for gene therapy and the like.

    摘要: The present invention relates to a method of selecting high producer clones by using an expression vector, the expression vector comprising: (i) a gene expression cassette comprising a selectable marker gene to which polyA has been inoperably linked; and (ii) a gene expression cassette which encodes a recombinant protein of interest and to which polyA has been operably linked. According to the invention, high producer clones can be selected from cell populations at least 10 times fewer than in the existing methods of selecting cell lines. Particularly, high producer clones can be selected using a low concentration of MTX compared to a conventional stepwise gene amplification strategy which comprises carrying out multiple amplification steps while increasing the concentration of MTX. Accordingly, the development period of cell lines can be shortened and the labor and cost required for selection of high-productivity cell clones can be reduced, whereby more efficient production of proteins is possible even when general selectable marker genes other than MTX are used.
