Immunohistochemical staining for E-cadherin (B, C, D), COX-2 (F, G, H) and Snail (J, K, M) in non-neoplastic adjacent mucosa (B, F, J), adenomas (C, G, K), and cancers (D, H, M). (A) Membranous E-cadherin expressions were significantly abnormal in cancers and adenomas than in non-neoplastic epithelium (p < 0.001). (E, I) In contrast, Snail and COX-2 expressions were significantly higher in cancers than in adenomas and non-neoplastic epithelium (p < 0.05, p < 0.001). COX-2, cyclooxygenase-2.
