Abstract (en)

[origin: DE4424761C1] The object of the invention is to construct a vector for antisense and ribozyme expression capable of expressing a determined and desired ribozyme or antisense sequence in a cell in a continuous and stable manner. The invention has applications in molecular biology and genetic engineering. The disclosed expression cassette is characterised in that it contains a strong promoter, preferably a T7 promoter, an adenoviral va-RNA-gene, a stable loop region and an insertion site for antisense/ribozyme sequences in the loop region. The T7 promoter is preferably associated with a T7 polymerase. The loop region is located in a restriction site in the central part of the adenoviral va-RNA gene and it preferably contains at least 2x21 bases having the same sequence.
