DNMT1 and nasopharyngeal carcinoma: DNMT1 and DNMT3B are upregulated in EBVaGC (latency I) [94,95] by LMP2A [94]; DNMT1, DNMT3A, and DNMT3B are upregulated in EBV-associated nasopharyngeal carcinoma (NPC; latency II) by LMP1 [76,77,113]; lastly, DNMT3A levels are increased in Hodgkin’s lymphoma cell lines (latency II) as well as lymphoblastoid cell lines derived from EBV-positive germinal center B cells (latency III) by an unknown viral gene [75] (Figure 2B).
