Hairy gene homolog increases nasopharyngeal carcinoma cell stemness by upregulating Bmi-1
Figure 1. Bmi-1 was markedly upregulated in NPC clinical tissue specimens. (A) Bmi-1 levels were detected using qRT-PCR in the NPC cell lines shown. (B) Representative photographs from immunohistochemical analyses of Bmi-1 protein levels in NPC tissues and non-cancerous nasopharyngeal epithelial tissues. (C) Bmi-1 levels were significantly greater in NPC tissues than in non-cancerous nasopharyngeal epithelial tissues (P < 0.001, χ2 test).
