Separation of pepsin I, pepsin II A, pepsin II B, and pepsin III from human gastric mucosa [PDF]
American Journal of Physiology-Legacy Content, 1963 Extracts of human gastric mucosa have been fractionated on diethylaminoethyl cellulose to yield three precursors of proteolytic enzymes active at low pH which have been called pepsinogen I, pepsinogen II, and pepsinogen III. Pepsinogen I has been found in the mucosa from all parts of the stomach examined as well as in the proximal duodenum. Pepsinogen

High Ionic Strength Enhances the Anti-Pepsin Activity of Titanium Dioxide Nanoparticles
Nano Biomedicine and Engineering, 2016 Gastro-esophageal reflux disease (GERD) is a state that evolves when there is a return of acid and pepsin enzyme into the esophagus. Inhibition of pepsin enzyme is one of the strategies used successfully for the treatment of GERD.

The Journal of General Physiology, 1962 Evidence relating to the structure and properties of swine pepsinogen and pepsin has been reviewed and used to suggest a tentative two dimensional picture of the skeleton of these two proteins. When pepsinogen, a folded single peptide chain, is converted to pepsin, there is a profound change in the physical and chemical properties of the protein. In an

ELECTROPHORESIS OF PEPSIN [PDF]
Journal of General Physiology, 1940 1. A number of pepsin solutions containing several protein components have been studied by the electrophoresis method. All samples show a homogeneous boundary moving to the anode at pH 4.4. 2. The activity of this material may be higher than that of the original solution on the basis of total nitrogen but is the same as that of the ...

Anti-pepsin activity of silicon dioxide nanoparticles
Revista Colombiana de Química, 2016 SiO2NPs as an inhibitor of pepsin enzyme for treatment of gastro-esophageal reflux disease (GERD) was used. Silicon dioxide nanoparticles (pepsin coated SiO2NPs) are among the safest nanoparticles that can be used inside the human body.

Immobilization of Pepsin onto Chitosan Silica Nanobeads with Glutaraldehyde as Crosslink Agent
Bulletin of Chemical Reaction Engineering & Catalysis, 2014 Glutaraldehyde crosslinked chitosan - silica nanobeads have been used as a support in the immobiliza-tion process of pepsin. The effect of pH, pepsin concentration, and temperature on the characteristics of both free and immobilized pepsin had been ...

Pepsin promotes IL-8 signaling-induced epithelial–mesenchymal transition in laryngeal carcinoma
Cancer Cell International, 2019 Background Laryngopharyngeal reflux (LPR), with its increasing morbidity, is attracting considerable attention. In recent years, the causal role between LPR and laryngeal carcinoma has been debated.
