Abstract:
The association between peptic ulcer diseases and polymorphisms in various genes, including HRH2, COX-1, IL-17A. IL-17F, MIF and Nrf2 genes, are seen. COX-1 has traditionally been regarded as a constitutively expressed enzyme that generates prostaglandins for gastrointestinal integrity. The effects of NSAID/aspirin on the gastric mucosal damage are caused by the inhibition of this enzyme. A T-1676C polymorphism (rs1330344) was significantly associated with the development of peptic ulcer, especially gastric ulcer. In addition, rs1330344 was also significantly associated with the development of NSAID/aspirin-induced ulcer diseases. In conclusions, the assessment for genotype of COX-1 gene promoter polymorphism, especially rs1330344, may be useful for detecting the high risk group of developing NSAID/aspirin-induced ulcer diseases.

Peptic Ulcer Disease II: Pathophysiology
Damaging agents such as Helicobacter pylori, gastric acid, pepsin, and nonsteroidal anti-inflammatory drugs (NSAIDs) can weaken the mucosal defense, allowing hydrogen ions to infiltrate back and harm epithelial cells.
Peptic Ulcer Disease I: Introduction
An acute ulcer, marked by superficial erosion and minimal inflammation, swiftly resolves upon identifying and addressing the underlying cause. In contrast, a chronic ulcer persists, potentially eroding through the muscular wall and forming fibrous tissue.

In the antrum region, G cells secrete the gastrin hormone that binds to gastrin-cholecystokinin-B (CCK2) receptors on parietal and enterochromaffin-like (ECL) cells in the fundic glands. Simultaneously, the vagus nerve releases acetylcholine, which binds to M3...
