    摘要: Compositions for targeted mutagenesis of cell surface receptors for HIV and methods of their use are provided herein. The compositions include triplex-forming molecules that bind to duplex DNA in a sequence specific manner at target sites to form triple-stranded structures. The triplex-forming molecules can be triplex-forming oligonucleotides (TFOs) or peptide nucleic acids (PNAs). The triplex-forming molecules are useful to induce site-specific homologous recombination in mammalian cells when used in combination with donor oligonucleotides. The triplex-forming molecules target sites within or adjacent to genes that encodes cell surface receptors for human immunodeficiency virus (HIV). This binding stimulates homologous recombination of a donor oligonucleotide to cause mutations in HIV cell surface receptor genes that result in one or more deficiencies in the ability of the encoded receptor to bind to HIV and allow its transport into the cell. Methods for ex vivo and in vivo prophylaxis and therapy of HIV infection using the disclosed compositions are also provided.

    摘要: A high affinity, triplex-forming oligonucleotide and methods for use thereof wherein an oligonucleotide is used to form a triple-stranded nucleic acid molecule with a specific DNA segment of a target DNA molecule. Upon formation of the triplex, the binding of the oligonucleotide stimulates mutagenesis within or adjacent to the target sequence using cellular DNA synthesis or repair mechanisms thereby producing heritable changes in a human or animal. The mutation activates, inactivates or alters the activity and function of the target molecule. This mutation may be the result of a recombinagenic mechanism induced by the oligonucleotide.

    摘要: Compositions and methods for treating lysosomal storage diseases are disclosed. Lysosomal dysfunction is usually the result of deficiency of a single enzyme necessary for the metabolism of lipids, glycoproteins (sugar containing proteins) or mucopolysaccharides which are fated for breakdown or recycling. The compositions contain triplex-forming molecules which can be used to induce site-specific homologous recombination in mammalian cells when combined with donor DNA molecules, by stimulating cellular DNA synthesis, recombination, and repair mechanisms. The methods are particular useful for correcting point mutations in genes associated with lysosomal storage diseases such as Gaucher's disease, Fabry disease, and Hurler syndrome. Methods for determining the frequency of target gene repair and assessing the restoration of the enzymatic activity of corrected polypeptides are also disclosed. Ex vivo and in vivo methods of gene correction in patients are also provided.

    摘要: Compositions for targeted mutagenesis of cell surface receptors for HIV and methods of their use are provided herein. The compositions include triplex-forming molecules that displace the polypyrimidine strand of target duplex and form a triple-stranded structure and hybrid duplex in a sequence specific manner with the polypurine strand of the target duplex. The triplex-forming molecules include a mixed-sequence “tail” which increases the stringency of binding to the target duplex, improves the frequency of modification at the target site, and reduces the requirement for a polypurine:polypyrimidine stretch. Methods for using the triplex-forming molecules in combination with one or more donor oligonucleotides for targeted modification of sites within or adjacent to genes that encodes cell surface receptors for human immunodeficiency virus (HIV) are also disclosed. Methods for ex vivo and in vivo prophylaxis and therapy of HIV infection using the disclosed compositions are also provided.

    摘要: Compositions and methods for targeted gene therapy are disclosed. Compositions containing double duplex-forming pseudocomplementary oligonucleotides are administered in combination with a donor oligonucleotide that is homologous to a target sequence on a double-stranded DNA molecule in need of repair or replacement. By activating cellular mechanisms involved in DNA synthesis, repair and recombination, the double duplex-forming pseudocomplementary oligonucleotides can introduce one or more mutations at a site of interest by increasing the efficiency of targeted recombination of the donor oligonucleotide. The pseudocomplementary oligonucleotides/donor oligonucleotide compositions may be administered in combination with a second therapeutic agent that enhances access of the pseudocomplementary oligonucleotides and/or the donor oligonucleotide to the target site, an agent that enhances or increases DNA repair or recombination, or an agent that enhances uptake or delivery of the oligonucleotides.
