Abstract
The present invention relates to a recombination vector, a transformation cell into which the recombinant vector is introduced, a ribozyme expressed from the recombination vector, a prophylactic or therapeutic composition for liver cancer comprising the recombination vector and the ribozyme, and a therapeutic method for liver cancer using the composition, said recombination vector comprising: a tissue-specific promoter; and a ribozyme-target gene expression cassette comprising a trans-splicing ribozyme targeting a cancer-specific gene and a target gene connected to the 3' exon of the ribozyme, wherein a splicing donor/splicing acceptor sequence (SD/SA sequence) is connected to the 5′ end of the ribozyme-target gene expression cassette, woodchuck hepatitis virus posttranscriptional regulatory element (WPRE) is connected to the 3′ end of the ribozyme-target gene expression cassette, and a nucleic acid sequence recognizing a micro RNA-122a (microRNA-122a, miR-122a) is further connected to the 3′ end of the WPRE.
