ABSTRACT
Objective To study the biological significance of the common mutant preC/C gene in clinical HBV in China. Methods Site directed mutagenesis based on the unique enzyme site elimination was used to construct eukaryocyte expression vector with mutant HBV/C gene(V60、G87、L97). Expression vectors with wild and mutant preC/C gene were transferred into HepG2 cell. Culture supernatant was detected by ELISA for HBeAg. Results Result of DNA sequencing showed that the constructed mutant HBV preC/C gene had only one specific site variation compared with the wild type sequence. Goal DNA fragment was detected positive in the HepG2 cells transferred with wild and mutant preC/C gene. A value of HBeAg in the supernatant of the cells harboring L97 variant was higher than that of the wild and other variant strains( P
