Research Themes

Inflammatory host responses in gastrointestinal tumorigenesis

Inflammatory host responses in gastrointestinal tumorigenesis Inflammatory responses recruit and activate macrophages in gastric mucosa.
TNF-alpha derived from activated macrophages promote Wnt signaling activity
of surrounding gastric cancer cells, which contribute to gastric tumorigenesis.

Cooperation of Wnt signaling and COX-2 pathway in gastrointeitinal tumorigenesis

Cooperation of Wnt signaling and COX-2 pathway in gastrointeitinal tumorigenesis Although activation of Wnt signaling causes dysplastic changes of gastric epithelial cells, it is not enough for gastric tumor formation. Cooperation of Wnt and COX-2 pathway result ingastric tumor development.
We have genetically demonstrated such crosstalk in gastric cancer development by construction of K19-Wnt1/C2mE mice.
