Description: Pepsinogen C (progastricsin), also known as PGC, is an aspartic proteinase that belongs to the peptidase family A1. Pepsin C, the activated protease is a digestive enzyme that is produced in the stomach and constitutes a main component of the gastric mucosa. At low pH conditions, pepsinogen C undergoes conversion into active enzyme. Pepsinogen C has been found expressed in all regions of the stomach mucosa and also in the proximal duodenal mucosa. In stomach cancer tissues and cancer cell lines, the expressions of the pepsinogen genes were declined or lost, in good accordance with their pepsinogen productions. No gross structural changes of the pepsinogen genes were noticed in these cancers, but the methylation patterns of the pepsinogen genes were found to be altered in diverse ways in different cancers. Serum levels of this enzyme are used as a biomarker for certain gastric diseases including Helicobacter pylori related gastritis.
