    摘要: The present invention provides an isolated nucleic acid comprising: a) at least one first nucleotide sequence encoding a heterologous nucleotide sequence of interest; and b) at least two second heterologous nucleotide sequences, wherein each second heterologous nucleotide sequences comprises: i) a first set of splice elements defining a first intron that is removed by splicing to produce a first RNA molecule that imparts a biological function in the absence of activity at a second set of splice elements; and ii) the second set of splice elements defining one or more introns different from said first intron, wherein said one or more introns different from said first intron are removed by splicing to produce no RNA molecule and/or a second RNA molecule that docs not impart a biological function, when said second set of splice elements is active. Further provided are methods of using the nucleic acid of this invention to regulate transgene expression.

    摘要: The present invention relates to a method for producing helper-free stocks of recombinant adeno-associated virus (rAAV) which can be used to efficiently and stably transduce foreign genes into host cells or organisms. The method comprises the cotransfection of eukaryotic cells with rAAV and with helper AAV DNA in the presence of helper virus (e.g. adenovirus or herpesvirus) such that the helper AAV DNA is not associated with virion formation. The crux of the invention lies in the inability of the helper AAV DNA to recombine with rAAV vector, thereby preventing the generation of wild-type virus. In a specific embodiment of the invention, the vector comprises a recombinant AAV genome containing only the terminal regions of the AAV chromosome bracketing a non-viral gene, and the helper AAV DNA comprises a recombinant AAV genome containing that part of the AAV genome which is not present in the vector, and in which the AAV terminal regions are replaced by adenovirus sequences. In a further embodiment of the invention, cell lines are created which incorporate helper AAV DNA which can directly produce substantially pure recombinant AAV virus. The pure stocks of recombinant AAV produced according to the invention provide an AAV viral expression vector system with increased yield of recombinant virus, improved efficiency, higher definition, and greater safety than presently used systems.
