As a corresponding result, all the EBV‐positive cells, including EBV‐genome transfected cells (C2089), NPC cells (C666‐1), gastric cancer cells (AGS‐EBV), and lymphoma cells (Raji), exhibited higher levels of exosomal CYPA when compared with EBV‐negative cells (293, HK‐1, 5‐8F, AGS‐, BJAB) (Figure 5B‐E). The gene discussed is PPIA; the disease is lymphoma.
