Summary
Epstein-Barr virus (EBV) drives gastric cancer by altering cell epigenetics. EBV
Area of Science:
- Oncology
- Virology
- Epigenetics
Context:
- Epstein-Barr virus (EBV) is linked to approximately 10% of gastric carcinoma (GC) cases.
- EBV-associated GC involves monoclonal growth of infected epithelial cells with a specific latency I gene expression program.
Purpose:
- To investigate the molecular mechanisms underlying EBV-associated gastric carcinoma.
- To explore the role of epigenetic alterations and viral proteins in GC development.
Summary:
- The primary molecular abnormality in EBV-associated GC is global CpG island methylation in cancer-related gene promoters.
- Experimental EBV infection induces both EBV-specific and gastric cancer epigenotypes in gastric cells.
- Viral latent membrane protein 2A (LMP2A) contributes to DNA methylation promotion via STAT3-mediated DNMT1 upregulation.
Impact:
- This research elucidates a key viral-cellular interaction mechanism in gastric cancer pathogenesis.
- Understanding these epigenetic changes may reveal novel therapeutic targets for EBV-associated GC.

01:26Gastritis II: Pathophysiology
The pathophysiology of gastritis begins with the colonization of the stomach lining by Helicobacter pylori (H. pylori). This bacterium spreads mainly via the oral-oral route through saliva or shared utensils, and can also be transmitted in overcrowded or unhygienic environments through contaminated water, despite its brief survival outside the body.ColonizationOnce ingested, H. pylori enters the stomach and begins colonization by navigating through the mucus layer lining the stomach wall. It...
01:17Gastritis-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...

01:27Peptic Ulcer
Peptic ulcers are erosive lesions of the gastric or duodenal lining, most commonly caused by Helicobacter pylori infection. This Gram-negative, helical bacterium has adapted to survive the stomach’s acidic environment by producing urease, which converts urea into ammonia and carbon dioxide. The ammonia neutralizes gastric acid in the bacterium’s immediate environment, allowing colonization of the gastric mucosa. H. pylori attaches to mucus-secreting epithelial cells, penetrates the mucus...
01:21Barrett Esophagus-I: Introduction
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

01:03Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...
