Figure 2. The mRNA expressions of IL-6, JAK2, STAT3 and CyclinD1 were higher in NPC tissues than in normal nasopharyngeal epithelial tissues. *p < 0.05 when vs. normal nasopharyngeal epithelial tissues; NPC tissues (n = 117); Normal nasopharyngeal epithelial tissues (n = 112). Abbreviation: NPC: nasopharyngeal carcinoma.
