Clinical Significance

Description

Human progastrin consists of 80 amino acids and is cleaved to two biologically active forms, gastrin-34 and gastrin-17. Over 90% of the gastrin present in the antral mucosa is the G17 form. The secretion of G-17 is mainly affected by intragastric pH value, G cell number and diet. It is a sensitive indicator of the secretory function of gastric antrum and plays important roles in the diagnosis and screening of atrophic gastritis and gastric cancer.
