  • Patent number: 5371206
    Abstract: The present invention relates to novel chimeric fibroblast growth factors (FGF) wherein the alanine at amino acid 3 and serine 5 of native human recombinant basic fibroblast growth factor are replaced with glutamic acid. The N-terminus sequence of the present chimeric FGFs identify homology with that of human acidic fibroblast growth factor. The mitogenic properties of the native human recombinant basic FGF are exhibited by the present chimeric FGFs, and they are efficiently expressed in E. coli at significantly greater yields that previously reported. Novel variants of this new glu.sup.3,5 basic fibroblast growth factor, such as those in which cysteine 78 and cysteine 96 are replaced, e.g., with serine or other amino acids, to produce stabilized versions of the glu.sup.3,5 basic FGF and eliminate disulfide scrambled forms, are also described.

  • Patent number: 5352779
    Abstract: Described are new glycoprotein hormones capable of competing with natural hormones for the normal receptor binding sites but substantially incapable of effecting post receptor activities. The glycoprotein hormones of the present invention have had specific (rather than all) oligosaccharide chains removed so as to effectively diminish biologic activity while not significantly reducing plasma half-life, thus improving the molecules effectiveness as an antagonist compared with conventionally-produced molecules. The preferred glycoprotein hormones are ideally obtained by site-directed mutagenesis to selectively deglycosylate the protein. Also described are therapeutic treatments comprising the administration of the recombinant glycoprotein hormones of the present invention as hormone antagonists.

  • Patent number: 5332804
    Abstract: High molecular weight forms of therapeutic proteins are disclosed which are single-polypeptide-chain proteins that contain the same or similar therapeutic activity as the therapeutic protein. In particular, high molecular weight forms of the human bFGF angiogenic factor are disclosed which are single-polypeptide-chain proteins having at least one active site possessing an activity selected from the group consisting of mitogenic activity, chemotactic activity, angiogenic activity, neurotrophic activity, the ability to stimulate protease synthesis and combinations thereof. The high molecular weight angiogenic factors exhibit substantial homology to and are immunologically equivalent to the native high molecular weight forms isolatable from human hepatoma cells. The high molecular weight angiogenic factors are produced by DNA translation initiating at non-ATG codons and incorporate additional polypeptide sequences N-terminal to the human bFGF factor.

  • Patent number: 5304541
    Abstract: The present invention relates to the production of large quantities of a novel chimeric TGF-.beta., termed TGF-.beta.1/.beta.2, by eucaryotic host cells transfected with recombinant DNA vectors containing the TGF-.beta.1/.beta.2 precursor coding sequence controlled by expression regulatory elements. Simian TGF-.beta.1 cDNA (Sharples et al., 1987, DNA 6:239-244) was modified so that the nucleotides encoding amino acid residue numbers 9-13, 17, 19, 25 and 26 of the mature TGF-.beta.1 sequence were hanged to the nucleotides encoding the corresponding amino acids of the mature TGF-.beta.2 structure. Simian codon usage was maintained. The chimeric TGF-.beta.1/.beta.2 of the invention induces effects on the proliferation of vascular endothelial cells equivalent to those induced by TGF-.beta.1.
