    摘要： The invention relates to methods for the production of therapeutic proteins in mammalian cells. In one embodiment, the method comprises producing a therapeutic protein such as IGF-1 in a mammalian cell endogenously expressing a cognate receptor of said recombinant therapeutic protein and wherein binding of said therapeutic protein to said cognate receptor results in a low titer of the therapeutic protein, the method comprising with a mammalian cell being deficient in the expression of the cognate receptor of said therapeutic protein and being transformed with an expression vector comprising a nucleic acid molecule encoding the therapeutic protein: a. Cultivating said cell under conditions allowing the expression of the therapeutic protein; and b. Harvesting the therapeutic protein from the mammalian cell cultivated in step a, wherein said mammalian cell produces at least 1.5 fold more therapeutic protein than a cell in which the expression of the cognate receptor has not been so modified.
