    Abstract: The present invention relates techniques for identifying suitable secretion fusion partner (SFP) for hyper-secretory production of recombinant proteins. The SFPs can be obtained from secretome analyses. Recombinant proteins are produced in a fusion form with a secretion fusion partner (SFP) and can be separated from the SFP by in vitro protease treatment. SFPs of this invention greatly improve the secretion level of target proteins and peptides which are valuable for bio-pharmaceuticals and the bio-industry.

  • Patent number: 7704710
    Abstract: This invention relates to the diagnosis, treatment and methods for discovery of new therapeutics for atopic asthma and related disorders based on variants of Asthma Associated Factor 2. One embodiment of the invention is a variant of AAF2 wherein codon 173 is deleted resulting in the loss of glutamine 173 from the mature protein precursor. This single amino acid deletion results in a non-functional AAF2 protein and therefore the presence of this phenotype should be associated with less evidence of atopic asthma. Correspondingly, the lack of susceptibility to an asthmatic, atopic phenotype is characterized by the loss of glutamine at codon 171 The invention includes isolated DNA molecules which are variants of the wild type sequence as well as the proteins encoded by such DNA and the use of such DNA molecules and expressed protein in the diagnosis and treatment of atopic asthma.

    Abstract: A method is described for the expression of heterologous polypeptides in rodent cells. The method comprises the oriP/EBNA-1 episomal replication and maintenance system of the Epstein-Barr-Virus (EBV). With the stable integration of an EBNA-1-protein expression cassette under the control of a promoter into the genome of a rodent cell an EBNA-1-protein expression in the cells was obtained. The heterologous protein is expressed from an episome comprising an EBV origin of replication and a functional expression cassette of said heterologous protein. The invention further comprises transformed rodent cell lines, a method for the production of a heterologous protein in said cell lines and a kit for the construction of said cell lines.

    Abstract: Disclosed are compositions and methods for increasing the longevity of a cell culture and permitting the increased production of proteins, preferably recombinant proteins, such as antibodies, peptides, enzymes, growth factors, interleukins, interferons, hormones, and vaccines. Cells transfected with an apoptosis-inhibiting gene or vector, such as a triple mutant Bcl-2 gene, can survive longer in culture, resulting in extension of the state and yield of protein biosynthesis. Such transfected cells exhibit maximal cell densities that equal or exceed the maximal density achieved by the parent cell lines. Transfected cells can also be pre-adapted for growth in serum-free medium, greatly decreasing the time required to obtain protein production in serum-free medium. In certain methods, the pre-adapted cells can be used for protein production following transformation under serum-free conditions. The method preferably involves eukaryotic cells, more preferably mammalian cells.

  • Publication number: 20090142806
    Abstract: The present invention provides isolated and purified polynucleotides and polypeptides related to the IL-17F signaling pathway. The invention also provides antibodies to IL-17F homodimers and IL-17A/IL-17F heterodimers, and methods of isolating and purifying members of the IL-17 family, including IL-17A/IL-17F heterodimers, from a natural source. The present invention also is directed to novel methods for diagnosing, prognosing, monitoring the progress of, and treating and/or preventing disorders related to IL-17F signaling, i.e., IL-17F-associated disorders, including, but not limited to, inflammatory disorders, such as autoimmune diseases (e.g., arthritis (including rheumatoid arthritis), psoriasis, systemic lupus erythematosus, and multiple sclerosis), respiratory diseases (e.g., COPD, cystic fibrosis, asthma, allergy), transplant rejection (including solid organ transplant rejection), and inflammatory bowel diseases or disorders (IBDs, e.g., ulcerative colitis, Crohn's disease).
