Abstract
The trefoil factor family 2 (TFF2), a member of the trefoil factor family, plays a critical role in maintaining homeostasis throughout the gastrointestinal tract. In the present study, we expressed recombinant human TFF2 by Escherichia coli expression system with the purity above 95%. In an in vitro simulated gastrointestinal environment, rhTFF2 was shown to exhibit resistance to proteases, heat, acid and alkali. In addition, in mouse burn-induced gastric injury models, rhTFF2 was demonstrated to accelerate the healing of gastric mucosal lesions. This study provides a new way to treat burn-induced gastric injury.
