| Outline of Final Research Achievements |
The aim of this study was to evaluate gene expression in the H. pylori-infected gastric mucosa of children using microarray and other analyses. Gastric mucosal samples were obtained from antrum and corpus from 24 patients (12 adults and 12 children) who had undergone endoscopic evaluation of chronic abdominal complaints and were examined. Six adult and pediatric patients with and six without (total, 24) H. pylori infection were enrolled.
The expression of inflammatory molecules was up-regulated in the H. pylori-infected gastric mucosa from both adults and children. The expression of OLFM4 was only up-regulated in adult patients, while that of PIM2, REG3A, LCN2 and CXCL 13 was equally up-regulated in the infected gastric mucosa of both.
Because several carcinogenic molecules are up-regulated in H.pylori-infected gastric mucosa even in childhood, early eradication therapy from childhood may be beneficial to decrease the incidence of gastric cancer.
