- Abstract
Epstein-Barr virus (EBV) has the potential to undergo latent and lytic pathways during infection. However, expression of many of the viral genes during the lytic-latent transition remains unclear. In this study, we investigated the effects of 12-O-tetradecanoylphorbol-13-acetate (TPA) and hydroxyurea (HU), two commonly used modulators of EBV life cycle, on the expression profiles of the entire genome of EBV persistent infected in B95-8 cells. After treatment with TPA for 48?h, the copy number of EBV genome in the cells increased about 2.5 fold, whereas HU treatment resulted in a reduction to approximately two-thirds of the original level. Except a small set of genes, the amounts of EBV mRNA are generally less abundant than that of ß-actin. The expression of a large fraction of the 80 EBV genes was found to be activated after TPA treatment with a noticeable increase of 19 and 21 fold, respectively in BSLF1 and BBLF4. In contrast, treatment of the B95-8 cells with HU, a nucleotide synthesis inhibitor, dramatically suppressed the expression of EBV lytic genes. In summary, we have demonstrated that real-time quantitative PCR is a reliable method to monitor the influence of drug-treatment in EBV genes regulation. Our results also provide a basis for further investigation on how the virus coordinates its own gene expression during latent-lytic pathway transition.
