Construction of two hepatocellular carcinoma cell models for the expression of HBV X gene with different selection characteristics / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To construct 2 hepatocellular carcinoma (HCC) cell models for the expression of HBV X gene with different selection characteristics.@*METHODS@#HepG2 HCC cells were infected with eukaryotic expression vectors with HBV X gene, pCEP4-X, and pcDNA3. 1 (+)-X. Single cell clone was selected by hygromycin and neomycin. After propagating culture for certain periods, the HBV X gene expression was identified by PCR, RT-PCR, and Western blot.@*RESULTS@#Single HCC cell clone with HBV X gene transferred resistant to hygromycin and neomycin was selectively cultured, and the cells could be propagated for certain periods. PCR, RT-PCR, and Western blot identified the expression of HBV X gene.@*CONCLUSION@#Two HCC cell models for the expression of HBV X gene with different selection characteristics have been successfully constructed.
