Objective To determine whether trefoil factor 1(TFF1) could be associated with healing of gastric mucosa and differentiation of gastric carcinoma. Methods TFF1 in normal and various pathologic gastric mucosa was assessed by immunohistochemical method and analyzed with Motic Images Advanced 3.0 software. Results Compared with normal mucosa, increased TFF1 was detected in gastritis, gastric ulcer and duodenal ulcer. TFF1 was in increased expression in multiple and compound ulcer than simple ulcer. There was no significant difference among gastric ulcer, duodenal ulcer, gastritis and simple ulcer. Increased TFF1 was detected in peripheral mucosa of the gastric adenocarcinoma as compared with normal mucosa. The expression of TFF1 in gastric adenocarcinoma was related to the differentiation of adenocarcinoma, that is, the more poorly differentiated, the lower expression of TFF1. Conclusion TFF1 may play a significant role in gastric mucosa protection and epithelial restitution. TFF1 may also contribute to the differentiation of gastric adenocarcinoma.
