High salt diet can down-regulate TFF2 expression level in gastric mucosa of MGs after H. pylori infection

摘要

This study aimed to elucidate the effect of Helicobacter pylori (H. pylori) and high salt diet on Trefoil factor 2 (TFF2) expression level of Mongolian gerbils (MGs) gastric mucosa. The results of H. pylori identification and histopathology showed that H. pylori infected MGs model was built successfully. According to the immunohistochemical staining results, 25% (4/16) of H. pylori infected MGs with high salt diet showed high TFF2 expression, which was significantly lower than H. pylori infection group 61% (11/18)(P = 0.045). The results suggested that High salt diet could down-regulated TFF2 expression level of MGs gastric mucosa induced by H. pylori infection.
