LMP2A protein expression in NPC, IM, and HD specimens. Upper panel: EBV-positive NPC cell line and xenografts. LMP2A expression was not detected in NPC cell line C666-1 and xenograft X666. Only weak and focally LMP2A expression was detected in xenograft X2117. Middle panel: Primary NPC biopsies. Weak expression of LMP2A was noted in three NPC samples (NPC6, 8, 11). A negative example (NPC2) was included. Lower panel: IM and HD. Strong LMP2A expression was detected in IM. Three positive examples of HD were included.
