EPHA2 and nasopharyngeal carcinoma: Cell counting kit-8 (CCK-8), plate colony formation, and 5-ethynyl-2′-deoxyuridine (EdU) incorporation labeling assay showed that EphA2-WT dramatically increased NPC cells proliferation in vitro, whereas EphA2-YA failed to do it as compared to endogenous EphA2 knockdown (Fig. 1b–d), indicating that Y772A mutation abolished the effects of EphA2-WT on NPC cell proliferation in vitro.
