Furthermore, the levels of RKIP, miR-450b-5p, NRF2, and NQO1 were notably associated with clinicopathological characteristics such as primary T stage (except for miR-450b-5p and NQO1), lymph node metastasis, and TNM stage, of NPC patients (Table 2), respectively. This evidence concerns the gene PEBP1 and nasopharyngeal carcinoma.
