PALM2AKAP2 and extranodal nasal NK/T cell lymphoma: Eventually, we found several genes with expression levels significantly higher in cell lines established from NK/T-cell lymphoma than those from CAEBV infection (Table 3): FGF14, PDCD4, PCNA, MAP2K4, ITGAX and AKAP2 were preferentially expressed in SNK/T cells established from nasal NK/T lymphoma.
