WebPepsinogen is a powerful and abundant protein digestive enzyme secreted by the gastric chief cells as a proenzyme and then converted by gastric acid in the gastric lumen to the active enzyme pepsin. The role of pepsin and its precursor in protein digestion was first described in the 19th century. WebBackground: Patients with negative anti-Helicobacter pylori antibody titer and high pepsinogen (PG) level (group A) are regarded as having a low risk for gastric cancer. However, gastric cancer cases are occasionally observed in this group. We aimed to elucidate the clinical features of gastric neoplasm in group A patients and reviewed …

WebApr 8, 2008 · The effectiveness of the pepsinogen filter test is thus receiving wide recognition, and the observed high efficiency of the serum test in cancer detection strongly indicates that gastric cancer tends to develop from the atrophic stomach as detected by low serum pepsinogen.
WebBackground: Helicobacter pylori infection causes chronic gastritis and results in increased serum concentrations of pepsinogens I and II as well as gastrin, while the ratio of pepsinogen I to II (I : II) is decreased. Inducible nitric oxide synthase (iNOS) is induced in H. pylori-associated gastritis and may modulate inflammation. WebPepsinogens consist of a single polypeptide chain with molecular weight of approximately 42,000 Da. Pepsinogens are mainly synthesized and secreted by the gastric chief cells of the human stomach before being converted into the proteolytic enzyme pepsin, which is crucial for the digestive processes in the stomach.
