    Abstract: The inventive method of producing a eukaryotic viral vector comprises contacting a eukaryotic cell, which comprises a unique enzyme that nicks or cleaves a DNA molecule, with a recombinant phage vector, or contacting a eukaryotic cell, which does not comprise a unique enzyme that nicks or cleaves a DNA molecule, simultaneously or sequentially, in either order, with (i) a unique enzyme that nicks or cleaves a DNA molecule, and (ii) a recombinant phage vector. The recombinant phage vector comprises the DNA molecule comprising (a) a eukaryotic viral vector genome comprising a coding sequence, (b) a phage packaging site that is not contained within the eukaryotic viral vector genome, and (c) a promoter that is operably linked to the coding sequence. Alternatively, the DNA molecule is not present within the recombinant phage vector. The eukaryotic cell is contacted with the first DNA molecule and a recombinant phage vector. The first DNA molecule comprises a replication deficient eukaryotic viral vector genome comprising at least one adenoviral inverted terminal repeat and a packaging signal. The recombinant phage vector comprises a second DNA molecule and a phage packaging site, wherein the second DNA molecule complements in trans the replication deficient eukaryotic viral vector genome. The DNA molecule(s) enter the eukaryotic cell, and the unique enzyme nicks or cleaves the DNA molecule in the eukaryotic cell in at least one region not contained within the eukaryotic viral vector genome, thereby inducing the production of and ultimately producing a eukaryotic viral vector.

    Abstract: The present invention provides a dual selection cassette (DSC) comprising first and second DNA segments having homology to a eukaryotic viral vector, positive and negative selection genes, each operably linked to their own promoter, and one or more unique restriction enzyme sites (URES) or sitey-directed homologous recombination sites. The present invention also provides a plasmid, pN/P, comprising an independent positive selection marker gene, an origin of replication, and a dual selection cassette. The dual selection cassette and pN/P plasmid can be used to produce eukaryotic gene transfer vectors without requiring temporally-linked double recombination events or the use of specialized bacterial strains that allow the replication of plasmids comprising defective origins of replication. This method usefully increases the ratio of desired to undesired plasmid and vector constructs. Additionally, this invention provides a method for the creation of eukaryotic viral vector libraries.

    Abstract: The present invention is directed to a method of prophylactically or therapeutically treating an animal for at least one ocular-related disorder, e.g., ocular neovascularization or age-related macular degeneration. The method comprises contacting an ocular cell with an expression vector comprising a nucleic acid sequence encoding an inhibitor of angiogenesis and the same or different nucleic acid sequence encoding a neurotrophic agent. The method also can comprise contacting an ocular cell with different expression vectors, each comprising a nucleic acid sequence encoding an inhibitor of angiogenesis and/or a nucleic acid sequence encoding a neurotrophic agent. In addition, the present invention provides a viral vector comprising a nucleic acid sequence encoding pigment epithelium-derived factor (PEDF) or a therapeutic fragment thereof.

    Abstract: The present invention provides a library of viral vectors, wherein each member comprises a first heterologous DNA encoding a first gene product and a second heterologous DNA encoding a second gene product. The first heterologous DNA is common to each member of the library, while the second heterologous DNA varies between members of the library. The present invention additionally provides a method of constructing a library of viral vectors. The method comprises carrying out homologous recombination between a first DNA molecule and a second DNA molecule to form a pool of intermediate viral vector genomes. One or more linear third DNA molecules are ligated into the pool of intermediate viral genomes to produce a library of viral vector genomes. Alternatively, homologous recombination between linear DNA molecules and recipient DNA molecules produces a library of viral vector genomes. The library of viral vector genomes is converted into a library of viral vectors.
