Protein expression level of AGO2 by immunohistochemical staining in representative NPC tissues and non-cancerous nasopharyngeal tissues. Panels a and b NPC tissues; Panels c and d non-cancerous nasopharyngeal tissues. Images in the box (left, magnification 200 ×) were enlarged and shown in the right (magnification 400 ×). The AGO2 protein was found to locate in the cytoplasm of malignant cells
