  • Patent number: 6262034
    Abstract: A means for obtaining efficient introduction of exogenous genes into a patient, with long term expression of the gene, is disclosed. The gene, under control of an appropriate promoter for expression in a particular cell type, is encapsulated or dispersed with a biocompatible, preferably biodegradable polymeric matrix, where the gene is able to diffuse out of the matrix over an extended period of time, for example, a period of three to twelve months or longer. The matrix is preferably in the form of a microparticle such as a microsphere (where the gene is dispersed throughout a solid polymeric matrix) or microcapsule (gene is stored in the core of a polymeric shell), a film, an implant, or a coating on a device such as a stent.

  • Patent number: 6225290
    Abstract: Intestinal epithelial cells of a mammalian subject are genetically altered to operatively incorporate a gene which expresses a protein which has a desired therapeutic effect. Intestinal cell transformation is accomplished by administration of a formulation composed primarily of naked DNA, and is preferably administered orally. Oral or other intragastrointestinal routes of administration provide a simple method of administration, while the use of naked nucleic acid avoids the complications associated with use of viral vectors to accomplish gene therapy. The expressed protein is secreted directly into the gastrointestinal tract and/or blood stream to obtain therapeutic blood levels of the protein thereby treating the patient in need of the protein. The transformed intestinal epithelial cells provide short or long term therapeutic cures for diseases associated with a deficiency in a particular protein or which are amenable to treatment by overexpression of a protein.

  • Patent number: 6207457
    Abstract: A novel targeted nucleotide sequence delivery and integration system is provided. The integration system employs nucleic acid constructs having a targeting sequence capable of binding AAV Rep and a heterologous nucleotide sequence arranged relative to the targeting sequence such that the targeting sequence is capable of directing the integration of the heterologous sequence into a target site in a recipient genome. The system further employs Rep expression products which provide integration functions effective to mediate the site-specific integration of the targeting sequence and the heterologous sequence into the recipient genome. Methods are described, whereby the nucleotide sequence integration system can deliver and efficiently integrate large nucleotide sequences into target sites in recipient cell genomes. Therapeutic methods are also provided, wherein the integration systems are used to insert various therapeutically relevant nucleotide sequences into selected cells from a subject.

  • Patent number: 6200801
    Abstract: Nucleic acids are compacted, substantially without aggregation, to facilitate their uptake by target cells of an organism to which the compacted material is administered. The nucleic acids may achieve a clinical effect as a result of gene expression, hybridization to endogenous nucleic acids whose expression is undesired, or site-specific integration so that a target gene is replaced, modified or deleted. The targeting may be enhanced by means of a target cell-binding moiety. The nucleic acid is preferably compacted to a condensed state.

  • Patent number: 6183988
    Abstract: The present invention is directed to a leukocyte-specific gene Sp140 and its associated protein. Since it has structural analogies to other regulatory proteins and is localized in the nuclear body of certain cell types, Sp140 may be a transcription regulator involved in the body's interaction with viruses and in promyelocytic leukemia. The Sp140 gene can be used in gene therapy for treating certain viral diseases, autoimmune disorders and cancers, while the Sp140 protein may be useful as a diagnostic and prognostic marker in the analysis of certain autoimmune disorders.
