Almost all NPC-derived LMP1 sequences clustered together, except for M-ABA which is likely selected for B-cell immortalizing properties during in vitro propagation of the NPC-derived virus and was therefore not included as a representative NPC isolate in further analysis (Figure 2) [90,92,93,95,96,97,98]. Here, PDLIM7 is linked to nasopharyngeal carcinoma.
