Anti-pepsin activity of silicon dioxide nanoparticles [PDF]
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.

Combined laryngopharyngeal reflux and obstructive sleep apnea (CLOSA) – Salivary pepsin test for laryngopharyngeal reflux in obstructive sleep apnea patients [PDF]
Objectives: Reflux disease including gastroesophageal reflux and laryngopharyngeal reflux (LPR) is often found in obstructive sleep apnea (OSA) patients. Endoscopic examination is a gold standard diagnosis for reflux disease.

Analyzing pepsin degradation assay conditions used for allergenicity assessments to ensure that pepsin susceptible and pepsin resistant dietary proteins are distinguishable. [PDF]
The susceptibility of a dietary protein to proteolytic degradation by digestive enzymes, such as gastric pepsin, provides information on the likelihood of systemic exposure to a structurally intact and biologically active macromolecule, thus informing on

Separation of pepsin I, pepsin II A, pepsin II B, and pepsin III from human gastric mucosa [PDF]
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

Pepsin D. A minor component of commercial pepsin preparations [PDF]
Methods are described for the isolation and purification of pepsin D, an enzyme which accounts for about 10% of the enzymic activity in commercial preparations of pepsin. Pepsin D is similar to pepsin in having a molecular weight of about 35000, the same C-terminal amino acid sequence, and an N-terminal isoleucine residue.

Effects of pepsin and pepstatin on reflux tonsil hypertrophy in vitro. [PDF]
There is evidence that pepsin can aggravate tonsil hypertrophy. Pepstatin is a potent inhibitor of pepsin activity and could protect patients against reflux tonsil hypertrophy by inhibiting pepsin.

Pepsin plays an important role in laryngopharyngeal reflux (LPR), a risk factor for the development of hypopharyngeal squamous cell carcinomas (HPSCC). However, the role of pepsin in HPSCC is not clear.

The In Vitro Effect of Acidic-Pepsin on Nuclear Factor KappaB Activation and Its Related Oncogenic Effect on Normal Human Hypopharyngeal Cells. [PDF]
Extra-esophageal carcinogenesis has been widely discussed in relation to the chronic effects of laryngopharyngeal reflux and most prominently with pepsin historically central to this discussion.
