CENPN and nasopharyngeal carcinoma: To further investigate the expression level of CENP-N in NPC, we used a large sample of NPC patients with TMA immunohistochemical staining scores, and the immunohistochemical scores were analyzed with the chi-square test: CENP-N expression was elevated in NPC tissues, and the difference was statistically significant (Fig. 1c-d and Supplementary Table 6, P < 0.05).
