ABSTRACT
<p><b>OBJECTIVE</b>o study the replication of hepatitis B virus (HBV) in HepG2 cells infected with Ad-1.2 HBV.</p><p><b>METHODS</b>HepG2 cells were transfected with adenovirus containing 1.2 copies of HBV DNA. The expression of HBV antigens were detected in the culture medium by means of enzyme-linked immunosorbent assay (ELISA), and the covalently closed circular DNA (cccDNA) in the cells was extracted with plasmid extraction kit and detected by real-time PCR with selective primer after treatment with mung bean nuclease.</p><p><b>RESULTS</b>HBsAg, HBeAg and HBV cccDNA were all detected in HepG2 cells after tranfection with Ad-1.2 HBV. HBV cccDNA was detected 1 day after the infection, reaching the peak level 4 days after infection.</p><p><b>CONCLUSION</b>Ad-1.2 HBV-infected cells can serve as the model for screening and evaluation of antiviral agents.</p>
