    Abstract: The present invention relates to a cell line in which an expression construct is introduced into a genomic DNA, the expression construct including: (a) a promoter operable in animal cells and heterologous to adenoviruses; and (b) a modified adenovirus E1 coding gene sequence of SEQ ID NO:1 operatively linked to the promoter. According to the present invention, the cell line of the present invention is a novel cell line which is less likely to produce a replication competent adenovirus (RCA). The adenovirus producing cell line of the present invention has a low possibility of producing RCA due to homologous recombination, when compared with conventional cell lines. Therefore, this makes it possible to regulate the required amount of virus during gene therapy using the adenovirus and prevent tissue damage and toxic effects caused by overproduction of the adenovirus.

  • Patent number: 8846373
    Abstract: The present invention relates to new methods to promote sialylation of glycoconjugates, including recombinant glycoproteins, in glycoconjugate production systems. The invention relates to methods to promote efficient glycoconjugate sialylation in recombinant expression systems, by providing simpler and more economical ways to produce large intracellular pools of sialic acid precursors. The invention is directed to nucleic acids, vectors, and cells harboring vectors comprising nucleic acids encoding enzymes involved in the synthesis of sialic acid precursors, and cells harboring these nucleic acids in combination with nucleic acids encoding glycosyltransferases, including sialyltransferases, to facilitate the production of humanized recombinant glycoproteins in bacterial, fungal, plant, and animal cell expression systems.

    Abstract: Genetically modified somatic cells of a non-human animal are provided that are engineered to contain a self-excisable, recombinase expression cassette comprising a site-specific recombinase gene operably linked to an ES cell-specific promoter. Compositions and methods for producing a genetically modified, cloned non-human animal that is free of a selective marker gene and a recombinase gene are provided, wherein a targeting construct comprising a self-excisable recombinase gene operably linked to an ES cell-specific promoter is introduced into differentiated somatic cells. The genetically modified genome of the somatic cells is transferred into an enucleated host oocyte. The artificially created zygote is then cultured in vitro until the blastocyst embryonic stage and subsequently implanted into a uterus of a surrogate mother to form a genetically modified, cloned non-human animal free of selective marker and recombinase genes.
