PDLIM7 and nasopharyngeal carcinoma: The results are shown in Figure 2A and B. The ability of colony formation after ionizing radiation (IR) was essentially unchanged between the groups treated with the EVs from CNE1 cells and the untreated groups but was significantly enhanced in the groups treated with the EVs from CNE1‐LMP1 cells (P < .01 for HK1 and P < .05 for HONE1), which illustrated the functions of EVs derived from LMP1‐positive NPC cells in mediating the radioresistance of NPC cells.
