To determine if the Zp-V3 sequence enhances the ability of B95.8 virus to lytically reactivate in stably infected cell lines, we infected EBV-negative Mutu cells (derived from a Burkitt lymphoma) with WT, revertant, or Zp-V3 mutant B95.8 viruses, and used hygromycin selection to obtain stably infected cell lines. Here, HEPHL1 is linked to Burkitt lymphoma.
