Fig 1: High expression levels of hub genes were significantly associated with a low overall survival rate. (A–E) Representative images of immunofluorescence staining for AURKA, BUB1, CDK1, CCNA2, and CCNB2 in NPC samples. (F–J) Kaplan–Meier curves of patients with different expression levels of AURKA, BUB1, CDK1, CCNA2, and CCNB2. Control: nasopharyngeal carcinoma tissues from patients who survived during follow-up. Death: nasopharyngeal carcinoma tissues from patients who died during follow-up. ns, not significant. **, p < 0.01 vs. Control group. ***, p < 0.001 vs. Control group.
