Comparison of of NUCB-2 expression between samples of clinical NPC and rhinitis. (A) Display of NUCB-2 expression detected by Western blot in six nasopharyngeal carcinoma tissues and two rhinitis controls, where GAPDH was used as the internal control of each sample. (B) Presentation of NUCB-2 expression detected by immunohistochemical staining on frozen sections of NPC and rhinitis, where human gastric cancer tissue served as the negative control. The NUCB-2 protein was stained brown in cytoplasm while the nuclei were stained blue. (C) Comparison of nesfatin-1 concentration in serum between patients with NPC (n = 49), head and neck (HN) cancer (n = 35), rhinitis (n = 20) and healthy donors (n = 36). *: P < 0.05; ns: non-significant with P > 0.05
