PDLIM7 and neoplasm: We also compared the level of the lytic immediate-early viral protein, BZLF1, in P3HR1 tumor foci that were LMP1-high/EBNA-LP-low versus EBNA-LP-high /LMP1-low using IHC analysis (Fig 7). We found that BZLF1-positive cells are much more common in the EBNA-LP-high/LMP1-low tumor foci compared to the LMP1-high/EBNA-LP-low foci.
