In order to verify the biological effect of CATR and cisplatin in EBV‐LMP1 NPC cells, cells were divided into a control group, CATR treatment‐only group, CDDP treatment (cisplatin treatment group) only group, and a combination of CDDP‐and CATR‐treated group, respectively. The gene discussed is PDLIM7; the disease is nasopharyngeal carcinoma.
