In contrast, the expression of BZW2 (P <0.001), DLL4 (P <0.001), GTPBP4 (P <0.001), LSM4 (P <0.001), MBD3 (P <0.001), PAICS (P <0.001), PALM2AKAP2 (P =0.001), PAQR4 (P <0.001), RUVBL1 (P =0.006) and TGS1 (P =0.124), correlated positively with worse prognosis in patients with NPC (Fig. 3C and Fig. s3). This evidence concerns the gene BZW2 and nasopharyngeal carcinoma.
