Insights

Non-steroidal anti-inflammatory drugs (NSAIDs) can cause gastric lesions by inducing cell death. Upregulating stress proteins protects gastric mucosal cells from NSAID-induced damage, suggesting their therapeutic potential.

Area of Science:

  • Gastroenterology
  • Cell Biology
  • Pharmacology

Background:

  • Non-steroidal anti-inflammatory drugs (NSAIDs) are a common cause of gastric lesions.
  • NSAID-induced gastric mucosal cell death is a key factor in lesion development.
  • Cellular protective mechanisms against NSAID toxicity are crucial.

Purpose of the Study:

  • To review the role of stress proteins in protecting the gastric mucosa from NSAIDs.
  • To summarize evidence for NSAID-induced upregulation of stress proteins.
  • To propose stress protein inducers as potential anti-ulcer therapeutics.

Main Methods:

  • In vitro studies on gastric mucosal cells exposed to NSAIDs.
  • In vivo studies investigating NSAID effects on gastric mucosa.
  • Analysis of stress protein expression (heat shock proteins, glucose-regulated proteins, heme oxygenase-1).

Main Results:

  • NSAIDs upregulate stress proteins in gastric mucosal cells both in vitro and in vivo.
  • Upregulated stress proteins confer resistance to NSAID-induced cell death in vitro.
  • Upregulated stress proteins protect the gastric mucosa from NSAID-induced lesions in vivo.

Conclusions:

  • Stress proteins play a significant protective role against NSAID-induced gastric damage.
  • NSAID-induced stress protein upregulation is a key mechanism of mucosal defense.
  • Non-toxic inducers of stress proteins represent a promising therapeutic strategy for anti-ulcer treatment.

Mucosal Barrier of the Stomach01:25

Mucosal Barrier of the Stomach

The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

Drugs for Peptic Ulcer Disease: Prostaglandin Analogs as Mucosal Protective Agents

The gastric mucosa produces prostaglandins E2 (PGE2) and prostacyclin (PGI2), crucial in maintaining gastric health. They exert cytoprotective effects, including increasing bicarbonate secretion, releasing protective mucin, reducing gastric acid output, and preventing harmful vasoconstriction. These effects are mediated through various receptors, such as EP1, EP2, EP3, and EP4.
Non-steroidal anti-inflammatory drugs (NSAIDs) can induce peptic ulcers by inhibiting cyclooxygenase, decreasing...

Drugs for Peptic Ulcer Disease: Sucralfate as Mucosal Protective Agents

In the intricate landscape of the gastric lumen, excessive acid secretion disrupts the natural defense mechanisms, weakening the mucus-bicarbonate barrier. This vulnerability allows pepsin to infiltrate epithelial cells, digesting mucosal proteins and triggering erosion, leading to ulcer formation.
In this scenario, mucosal protective agents like sucralfate play an essential role. Sucralfate, a complex of sulfated sucrose and aluminum hydroxide, demonstrates its usefulness in acidic conditions,...

Pathophysiology of Peptic Ulcer Disease: Mucosal Defense Factors

Peptic ulcer disease, commonly called PUD, represents a multifaceted condition characterized by disruptions in the lining of the gastrointestinal (GI)  tract. Central to the protection of the gastrointestinal lining is the mucosal-bicarbonate barrier. This physiological defense mechanism is a formidable shield against the corrosive effects of gastric acid and pepsin secretion in the stomach. Its role is pivotal in maintaining the structural integrity of the stomach's inner lining. Bicarbonate,...
Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
Pathophysiology of Peptic Ulcer Disease: Injurious Factors01:22

Pathophysiology of Peptic Ulcer Disease: Injurious Factors

Peptic ulcers are sores on the stomach's inner lining and the upper small intestine, which are the result of disruptions in the mucosal layer that houses parietal cells which produce gastric acid, and chief cells which secrete pepsinogen.
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...
