| Research Abstract |
In the cancer area of gastric mucosal epithelium from gastric cancer patients, we found a tendency that expression of proteinase-activated receptor-1 (PAR1) was positively correlated with infection levels of Helicobacter pylori (H. pylori), suggesting involvement of increased expression of PAR1 in the development of H. pylori-related gastric cancer. We also determined if H. pylori might possess PAR-activating proteinases in various cell lines. However, we did not find any proteinases that activate PAR1, PAR2 or PAR4, in the H. pylori extracts.
