Transforming growth factor alpha inhibits secretion of gastric acid.

Transforming growth factor alpha (TGF-alpha), a protein secreted by transformed cells and related to epidermal growth factor ( EGF), was tested for its effects on gastric acid secretion. Guinea pig gastric mucosae were mounted in Ussing chambers and the rate of acid release was monitored by the pH-stat method. When administered prior to the secretagogue, TGF-alpha prevented the histamine-induced increase in the rate of acid secretion. Similarly, TGF-alpha caused a decrease in the rate of acid release in tissues that had already been stimulated with histamine. These data show that TGF-alpha inhibits gastric acid secretion in a manner similar to EGF and that the two growth factors share at least one physiological action unrelated to their mitogenic properties.[1]
