when eight copies of the hiv-1 kappa b-like sequence were used to regulate beta-globin gene expression , transcription of this gene was activated by the hbv x gene in hepg2 cells and no beta-globin gene transcription was detected in the absence of the hbv x gene . beta-globin gene expression regulated by the activator protein 2 ( ap-2 ) binding sequence was not activated by the hbv x gene .
