Figure 1. RKIP reduction is correlated with NPC radioresistance and poor patient survival.
(A) a representative result of RKIP, phospho-ERK−1/2 and phospho-AKT immunohistochemical staining in normal nasopharyngeal mucosa (NNM), and radiosensitive and radioresistant NPC tissues. Original magnification, ×200. (B) Kaplan-Meier survival analysis for NPC patients according to the expression levels of RKIP. NPC patients with low RKIP expression have a significantly worse disease-free survival (left) and overall survival (right) than those with high RKIP expression.
