Abstract:
To investigate the inhibition of HBV expression by multi-target ribozyme-expressing adenovirus vector in vivo, the ribozyme and muta-ribozyme were cloned into adenovirus vector pAd-CMV. By using the adenovirus expression system, the two plasmids were co-transfected into 293 cell line with adenovirus gene recombinant plasmids pJM17. The recombinant adenovirus were detected by plaque assay. Then the recombinant adenovirus infected the 2.2.15 cells. Using ELISA, dot-bolt hybridization and image analysis system, the inhibition of HBV expression was detected. The ribozyme and muta-ribozyme were cloned into the adenovirus vector pAd-CMV. The recombinant adenovirus could infect 2.2.15 cells and express the ribozyme. The ribozyme could decrease the expression of HBeAg by 87.1%. All these results strongly indicate that ribozyme can inhibit HBV expression in the cell, which represents a potential gene therapy for HBV infection.
