ABSTRACT
Objective To establish a recombinant eukaryotic expression vector containing human interferon-?(IFN-?) cDNA,and investigate the expression of IFN-? gene in transfected hepatocellular carcinoma (HCC) cell lines. Methods pcDNA3-IFN-?,established by subcloning IFN-? cDNA into a mammalian expression vector pcDNA3,was mediated into HCC cell lines SMMC-7721 and QGY-7701 by lipofectamine. The transfected HCC cells were selected in RPMI1640 containing G418(400~700?g).RT-PCR analysis and ELISA assay were used for mRNA transcription and protein expression of IFN-? gene. Results IFN-? mRNA was detected only in pcDNA3-IFN-? transfected cell lines, and high levels of IFN-? protein were detected only in the supernatants of IFN-? gene-modified cell lines. Conclusions pcDNA3-IFN-? can stably expressIFN-? cDNA in the transfected HCC cell strains
