EPHA2 and nasopharyngeal carcinoma: To determine the role of pY772-EphA2 in NPC, we established NPC cell lines expressing the equal levels of exogenous EphA2-WT and EphA2-Y772A using endogenous EphA2 knockdown cells, an appropriate cell model for comparing the differences of biological functions in the EphA2-WT and EphA2-Y772A.
