Objective To study the influence of hepatitis B virus(HBV) replication and expressions of different viral genes on CDC37 level in hepatocytes.Methods We amplified and cloned 6 HBV genes(P,preS1,preS2,S,C and X) into pCMV expression vectors,which were transfected in Huh7 and HepG2 hepatoma cell lines,and CDC37 expression level in the cells was detected using Western blotting.Wealso cloned the promoter sequence of CDC37 into pGL3 vector,and co-transfected pGL3 with pCMV recombinant plasmids into Huh7 and HepG...
