Gastric cancer is the 5th most common cancer in the world. Most cases of gastric cancer are associated with infection by the bacteria Helicobacter pylori. The infection causes massive gastric inflammation, which damages the stomach, and promotes gastric carcinogenesis. The factors that regulate gastric inflammation and how the inflammatory microenvironment promotes cancer development are unclear. Our goal is to understand how inflammation promotes gastric cancer development to facilitate the discovery of new gastric cancer diagnostics and treatments.
