  • Patent number: 7598080
    Abstract: A method of diagnosing the source of local, acute inflammation has been developed based on the discovery that white cells have different patterns of gene expression, and therefore protein markers, depending on the origin of the inflammation. These differences can be readily accessed by analysis of the white cells obtained at a site to be analyzed, for example, in the synovial fluid of a knee. The analysis, by comparison with the analysis of white cells present in known conditions, can be used to differentiate between inflammation due to bacterial infection, arthritis or gout, for example. The examples demonstrate differential gene expression in cells present in synovial fluid biopsies from patients with confirmed bacterial infection as compared to patients with aseptic loosening or patients with inflammation due to gout.

  • Patent number: 7556942
    Abstract: Tumor suppressor genes (TSGs) play a major role in the pathogenesis of human cancers. Here, a new TSG designated hippo (hpo) is described, and the human homolog mst2 is identified as an additional TSG. hpo as a gene that regulates both cell proliferation and cell death in Drosophila, and encodes a Ste-20 family protein kinase that binds to and phosphorylates the tumor suppressor protein Salvador (Sav), which is known to interact with the Warts (Wts) protein kinase. Loss of hpo results in elevated transcription of the cell cycle regulator cyclin E and the cell-death inhibitor diap1, leading to increased proliferation and reduced apoptosis. Further, hpo, sav, and wts define a pathway that regulates diap1 at the transcriptional level. A human homolog of hpo completely rescues the overgrowth phenotype of Drosophila hpo? mutants.

In general terms, the methods may involve: increasing the pH of the cells to a pH of at least about pH 10.0 to produce an intermediate composition, and then, in the presence of a non-ionic detergent such as a polyoxyethylene alkyl ether, neutralizing the pH of the intermediate composition to produce the protein extract. Such methods can be used in conjunction with methods for detecting one or more target proteins in a sample, such as viral proteins. Systems, kits and compositions for practicing the subject methods are also provided.

  • Patent number: 7531327
    Abstract: Disclosed herein 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. By transfecting cells in culture with an apoptosis-inhibiting gene or vector, cells in culture can survive longer, resulting in extension of the state and yield of protein biosynthesis. Expression of the apoptosis-inhibitor within the cells, because it does not kill the cells, allows the cells, or an increased fraction thereof, to be maintained in culture for longer periods. This invention then allows for controlled, enhanced protein production of cell lines for commercial and research uses, particularly the enhanced production of growth factors, interferons, interleukins, hormones, enzymes, and monoclonal antibodies, and the like.

  • Patent number: 7527801
    Abstract: Immunogenic compositions that elicit immune responses against Norovirus and Sapovirus antigens are described. In particular, the invention relates to polynucleotides encoding one or more capsid proteins or other immunogenic viral polypeptides from one or more strains of Norovirus and/or Sapovirus, coexpression of such immunogenic viral polypeptides with adjuvants, and methods of using the polynucleotides in applications including immunization and production of immunogenic viral polypeptides and viral-like particles (VLPs). Methods for producing Norovirus- or Sapovirus-derived multiple epitope fusion antigens or polyproteins and immunogenic compositions comprising one or more immunogenic polypeptides, polynucleotides, VLPs, and/or adjuvants are also described.

  • Publication number: 20090111147
    Abstract: Disclosed herein are non-natural amino acids and polypeptides that include at least one non-natural amino acid, and methods for making such non-natural amino acids and polypeptides. The non-natural amino acids, by themselves or as a part of a polypeptide, can include a wide range of possible functionalities, but typical have at least one oxime, carbonyl, dicarbonyl, and/or hydroxylamine group. Also disclosed herein are non-natural amino acid polypeptides that are further modified post-translationally, methods for effecting such modifications, and methods for purifying such polypeptides. Typically, the modified non-natural amino acid polypeptides include at least one oxime, carbonyl, dicarbonyl, and/or hydroxylamine group. Further disclosed are methods for using such non-natural amino acid polypeptides and modified non-natural amino acid polypeptides, including therapeutic, diagnostic, and other biotechnology uses.

  • Patent number: 7521058
    Abstract: The invention relates to vaccines used in the eradication or control of pestivirus infections, particularly those used in pigs or ruminants. The invention provides nucleic acid, pestivirus-like particles and a pestivirus vaccine, comprising the nucleic acid or particles, which is capable of eliciting a proper immune response without having the ability to spread throughout the vaccinated animal, thereby avoiding the negative consequences of viral spread. Preferably, the immune response allows for serological discrimination between vaccinated animals and wild-type pestivirus infected animals.
