    摘要: The present invention provides a viral vector comprising a nucleic acid sequence encoding pigment epithelium-derived factor (PEDF) or a therapeutic fragment thereof. The nucleic acid sequence is operably linked to regulatory sequences necessary for expression of PEDF or a therapeutic fragment thereof. Preferably, the viral vector is an adenoviral vector or an adeno-associated viral vector. Also preferably, the viral vector further comprises one or more additional nucleic acid sequences encoding therapeutic substances other than PEDF.

    摘要: 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.

    摘要: The invention is directed to a method of delivering a gene product to an animal. The method comprises administering an expression vector comprising a nucleic acid sequence operably linked to a promoter and encoding a gene product, and upregulating transcription of the nucleic acid sequence in the ocular cell. The expression vector can be an adenoviral vector. The invention further provides a method of prophylactically or therapeutically treating an animal for at least one ocular-related disorder. The method comprises contacting an ocular cell with an expression vector comprising a nucleic acid sequence encoding an inhibitor of angiogenesis and/or a neurotrophic agent. In one aspect, the method further comprises upregulating transcription of the nucleic acid sequence. Preferably, if 2×108 adenoviral particles of the inventive method are administered to a mouse, the level of expression of the nucleic acid sequence is not diminished more than ten-fold at 28 days post-administration.

    摘要: 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.
