    • The invention relates to methods for the production of a recombinant protein in a mammalian cell and methods to enhance the production of recombinant proteins in mammalian cells. More in particular, the invention provides a cell for the production of a recombinant protein of interest wherein said cell is permissive to a polyomavirus and wherein said cell comprises the genetic elements A and B wherein A encodes a polyomaviral large T antigen or a functional equivalent thereof and B comprises a gene encoding a protein of interest under the functional control of a polyomaviral origin of replication or a functional equivalent thereof, wherein said cell lacks the capability to express a polyomaviral small T antigen or a functional equivalent thereof as well as the capability to express a polyomavirus capsid protein.
    • 本发明涉及用于在哺乳动物细胞中产生重组蛋白的方法以及增强哺乳动物细胞中重组蛋白产生的方法。 更具体地,本发明提供了用于产生感兴趣的重组蛋白质的细胞,其中所述细胞允许多瘤病毒,并且其中所述细胞包含遗传元件A和B,其中A编码多分子量大的抗原或其功能等同物 和B包含编码目的蛋白质的基因在复合多功能病毒复制起点或其功能等同物的功能控制下,其中所述细胞缺乏表达多细胞病毒小T抗原或其功能等同物的能力,以及 表达多瘤病毒衣壳蛋白。
