  • Publication number: 20120171722
    Abstract: The invention provides a method for producing polypeptide protein products and nucleic acid products having reduced levels of antigenicity in an animal being treated with a biologic product. Somatic cells are isolated from an animal, transformed into pluripotent stem cells, transfected with a nucleic acid(s) of interest, and re-differentiated towards somatic cells known to be high level producers of the desired nucleic acid product. The invention can be used to derive a general cell line to treat populations, racial specific cell lines to treat ethnic groups, or patient specific cell lines to treat individuals. Additionally, the invention provides a method to allow induced pluripotent stem cells to be re-differentiated towards their somatic cell of origin so that the cells can be used to therapeutically treat an animal without resulting teratoma formation.

    Abstract: Fabry disease results from an X-linked deficiency in the enzyme ?-galactosidase A. The present invention is directed to recombinant human ?-galactosidase A and provides baculovirus expression vectors and recombinant virus that provide stable expression of extracellular and intracellular levels of this enzyme in an insect cell culture. The recombinant-derived enzyme can be used in enzyme replacement therapy to treat Fabry patients. Composition useful in therapeutic administration of ?-galactosidase A are also provided.

  • Patent number: 7001994
    Abstract: Methods to introduce highly phosphorylated mannopyranosyl oligosaccharide derivatives containing mannose 6-phosphate (M6P), or other oligosaccharides bearing other terminal hexoses, to carbonyl groups on oxidized glycans of glycoproteins while retaining their biological activity are described. The methods are useful for modifying glycoproteins, including those produced by recombinant protein expression systems, to increase uptake by cell surface receptor-mediated mechanisms, thus improving their therapeutic efficacy in a variety of applications.

  • Patent number: 6936454
    Abstract: A method of fracturing a subterranean formation which surrounds a well bore comprises the steps of providing a fracturing fluid, and injecting the fracturing fluid into the well bore at a pressure sufficient to form fractures in the subterranean formation which surrounds the well bore. The pressure is then released from the fracturing fluid, after which the fluid may be removed from the well and the well placed into production. The fracturing fluid comprises an aqueous liquid, a polysaccharide soluble or dispersible in the aqueous liquid in an amount sufficient to increase the viscosity of the aqueous liquid, an enzyme breaker which degrades said polysaccharide at a temperature above 180° F. Fracturing fluid compositions and enzyme breaker systems useful for carrying out the invention are also disclosed.

  • Patent number: 6916829
    Abstract: Method for enhancing in a mammalian cell the activity of an enzyme associated with Gaucher Disease by administering a competitive inhibitor of glucocerebrosidase in an amount effective to enhance the activity of the enzyme. Preferred compounds for use in the method are imino sugars and related compounds. In particular, C8-12-alkyl derivatives of N-alkyl-deoxynojirimycin, isofagomine compounds, and calystegine compoiunds are effective to enhance glucocerebrosidase activity.
