ABSTRACT
ObjectiveTo observe the killing effect on hepatocellular carcinoma(HCC) cell lines by growth response-1(Egr-1) promoter activated herps simplex virus thymidine kinase (tk). MethodsPlasmid pET was constructed by fusing of Egr-1 promoter to the upstream of tk gene and transfect human hepatocellular carcinoma cell lines SMMC-7721(SMMC/ET) with lipofectamine as a delivery system. The cloned cells, after selected with G418, and exposure to ?-radiation by a 60Co source, were added with prodrug GCV. The viability of cell lines was observed. ResultsAfter irradiation, transfected cell lines (0.07?0.03) was killed by prodrug GCV at higher percentage compared with control group(0.88?0.12)(P
