  • Patent number: 7544499
    Abstract: The invention relates to the discovery of a novel Chondroitinase Glycoproteins (CHASEGP's), methods of manufacture, and potential uses in conditions where removal of chondroitin sulfates may be of therapeutic benefit. Chondroitinase Glycoproteins require both a substantial portion of the catalytic domain of the CHASEGP polypeptide and asparagine-linked glycosylation for optimal chondroitinase activity. The invention also includes carboxy-terminal deletion variants of CHASEGP that result in secreted variants of the protein to facilitate manufacture of a recombinant CHASEGP. Further described are suitable formulations of a substantially purified recombinant CHASEGP glycoprotein derived from a eukaryotic cell that generate the proper glycosylation required for its optimal activity. CHASEGP is useful for the degradation of glycosaminoglycans and chondroitin sulfate proteoglycans under clinical conditions where their removal is of therapeutic value.

  • Patent number: 7148201
    Abstract: The invention is based on the discovery of methods for purification of an acid active hyaluronidase found in human plasma (hpHAse), including both biochemical and immunoaffinity purification methods. The method of immunoaffinity purification of the invention is based on the discovery of a method for identifying antibodies that specifically bind native hpHAse (anti-native hpHAse antibodies), and anti-native hpHAse antibodies identified by this screening method. The invention also features an assay for sensitive detection of HAse activity using biotinylated hyaluronic acid (bHA). Purification and characterization of hpHAse lead to the inventors' additional discovery that hpHAse is encoded by the LuCa-1 gene, which gene is present in the human chromosome at 3p21.3, a region associated with tumor suppression. The invention additionally features methods of treating tumor-bearing patients by administration of hpHAse and/or transformation of cells with hpHAse-encoding DNA.

  • Publication number: 20030212021
    Abstract: The identification of the HYAL1 hyaluronidase enzyme as a human plasma-derived myeloid colony-stimulating factor (CSF), herein designated CSF5-hyaluronidase, its recombinant production and methods of use are described. This protein may be used for the treatment of myelosuppression as may occur after irradiation, chemotherapy or other diseases where an increase in leukocyte levels may be beneficial. For example, CSF5 may be used to enhance the immune response to viral infection or other diseases associated with immune suppression.
