    • The present invention provides a method of modulating gene expression by co-infection of cells with two or more interdependent replication-deficient adenoviral vectors, in particular by introducing into a cell, in any order or simultaneously, a first replication-deficient adenoviral vector comprising a first promoter and a first nucleic acid sequence which encodes a first gene product, wherein the first promoter regulates expression of the first gene product, and (b) a second replication-deficient adenoviral vector comprising a second promoter and a second nucleic acid sequence which encodes a second gene product, wherein the second promoter regulates in cis expression of the second gene product and is regulated in trans by the first gene product, and wherein the first promoter is different from the second promoter. The present invention also provides a method of modulating gene expression to produce a gene product, e.g., protein, a method for increasing the selective targeting for gene delivery of a particular type of cells, and interdependent adenoviral vectors appropriate for use in the methods of the present invention.
    • 本发明提供了通过用两个或更多个相互依赖的复制缺陷型腺病毒载体共感染细胞来调节基因表达的方法,特别是以任何顺序或同时引入细胞,第一复制缺陷型腺病毒载体包含 第一启动子和编码第一基因产物的第一核酸序列,其中第一启动子调节第一基因产物的表达,和(b)第二复制缺陷型腺病毒载体,其包含第二启动子和第二核酸序列,其编码 第二基因产物,其中第二启动子以第二基因产物的顺式表达调节,并被第一基因产物反转,并且其中第一启动子不同于第二启动子。 本发明还提供了调节基因表达以产生基因产物的方法,例如蛋白质,增加特定类型细胞的基因递送的选择性靶向的方法,以及适用于所述方法的相互依赖的腺病毒载体 本发明。

    • The invention provides an isolated or purified nucleic acid molecule consisting essentially of a nucleotide sequence of at least 1877 contiguous nucleotides of (a) SEQ ID NO: 1 or (b) a nucleotide sequence encoding an angiogenic factor, wherein the nucleotide sequence comprises cDNA comprising exons 1-5 of a vascular endothelial growth factor (VEGF) joined to genomic DNA comprising introns 5, 6, and 7 and exons 6, 7, and 8 of VEGF and further comprising a mutation in one or more of the splice donor, branch point, and splice acceptor regions contained in an exon selected from the group consisting of exons 5, 6, 7, and 8, wherein the mutation promotes the production of one isoform of VEGF as compared to another isoform of VEGF. Expression constructs, compositions, and cells comprising such a nucleic acid molecule also are provided by the invention.
