H. pylori, lipid loss and stomach cancer

H. pylori infection — a strong risk factor for stomach cancer — changes the composition of stomach lipids, which could offer new biomarkers for detecting premalignant changes, Vanderbilt researchers discovered.

Stomach bug hit-and-run

The H. pylori machinery that “injects” an oncoprotein into stomach cells contributes to the development of gastric cancer, Vanderbilt researchers demonstrate.

Vanderbilt team shows how stomach bug can trigger cancer

Researchers at Vanderbilt University and the University of Michigan in Ann Arbor have obtained the first high-resolution image of a molecular “machine” used by the insidious stomach bug Helicobacter pylori (H. pylori) to inject a cancer-causing protein into the stomach lining.
