HNRNPK and nasopharyngeal carcinoma: Figure 1a showed an analysis of 10 normal nasopharyngeal tissues and 31 NPC tissues. The expression of hnRNPK was significantly upregulated in NPC tissues compared to normal nasopharyngeal tissues. Meanwhile, we investigated the correlation between the hnRNPK expression and the overall survival rate of NPC patients. Figure 1b illustrated that higher hnRNPK expression in NPC was associated with a lower overall survival rate of patients.
