EBNA1 effects on EBV reactivation in NPC cells. HONE-Akata cells were treated with siRNA against GFP or EBNA1. (A and B) Equal amounts of cell lysates before (A) or after (B) NaB-TPA treatment were compared by Western blotting using antibodies against EBNA1, PML, BMRF1, BZLF1, and actin. (C) EBV genomic DNA was quantified before and after NaB-TPA treatment as described for Fig. 1D. Average levels are shown with standard deviations; the value for siGFP samples without NaB-TPA treatment was set to 1.
