Two pepsinogens (pepsinogens 1 and 2) were purified from the esophageal mucosa of the bullfrog (Rana catesbeiana), and their molecular weights were determined to be 40,100 and 39,200, respectively, by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The NH2-terminal 70-residue sequences of both pepsinogens are the same, including the 36-residue activation segment. Furthermore, a cDNA ...
Several minor pepsinogens, present in extracts of bovine fundic mucosa obtained from the fourth stomach or abomasum, were separated from the main pepsinogen by chromatography on hydroxyapatite at pH7.3. The major pepsinogen and two of these minor pepsinogens were studied in detail. All three zymogens have N-terminal Ser-Val-, C-terminal -Val-Ala and not more than 1mol of glucose/mol of protein;...
1. Carbenoxolone, in suspension at pH 4.0, inhibits swine pepsin A, and human pepsins 1,3 and 5. Human pepsin 5 is the most readily inhibited, and human pepsin 1 the least. 2. Inhibition occurs by a process which is time-dependent, temperature-dependent and proportional to the quantity of carbenoxolone suspended. 3. Carbenoxolone, in solution at pH 7.4 and pH 8.0, inhibits the activation of the...
Methods: A total of 1,123 adult subjects who participated in a health survey in Hirosaki City were studied. Infection of H. pylori was defined by both serum antibody and stool antigen test. The presence and the severity of atrophic gastritis were defined by the serum level of serum pepsinogens. Using 16S ribosomal RNA amplification from fecal samples, the relative abundance of Lactobacillus was...
