As shown in Table 1, the statistical data confirmed that Cks1 protein highly expressed in NPC tissues compared with non-tumor nasopharyngeal tissues (73% vs. 36%, P < 0.05), and p27kip1 protein frequently expressed in non- tumor nasopharyngeal tissues compared with NPC tissues (57% vs. 43%, P < 0.05). The gene discussed is CKS1B; the disease is neoplasm.
