129 cases of non-malignant gastric lesions and 171 cases of gastric carcinoma were studied immunohistochemically for pepsinogen C. PgC was constantly expressed at the bottom of the gastric glands irrespective of the disease. PgC was much more frequently observed in cancer patients (p < 0.001). PgC-positive were carcinoma tissues (38%), particularly of the intestinal type (53.4%), but also in mixed (40%) and diffuse (15.5%) types. PgC-negative carcinomas were more frequently observed in combination with PgC-positive areas of the surface epithelium (p < 0.001) and intestinal metaplasia (p < 0.05). PgC-positive dysplastic foci were observed in both groups of PgC-positive and PgC-negative malignant tumours.

D008679 Metaplasia A condition in which there is a change of one adult cell type to another similar adult cell type.
D010435 Pepsinogens Proenzymes secreted by chief cells, mucous neck cells, and pyloric gland cells, which are converted into pepsin in the presence of gastric acid or pepsin itself. (Dorland, 28th ed) In humans there are 2 related pepsinogen systems: PEPSINOGEN A (formerly pepsinogen I or pepsinogen) and PEPSINOGEN C (formerly pepsinogen II or progastricsin). Pepsinogen B is the name of a pepsinogen from pigs. Pepsinogen B

D005753 Gastric Mucosa Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.
