| Outline of Final Research Achievements |
Comprehensive microRNA (miRNA) analysis was analyzed for expression of microRNAs from gastric cancer tumor tissue and normal tissue. MiRNAs involved in epithelial mesenchymal transition correlated with distant metastasis of gastric cancer. Serum miR-203 was identified and it was shown that it was significantly lower in stage IV gastric cancer patients than in stage I - III gastric cancer patients, and this low expression was found to be an independent predictive marker of poor prognosis in gastric cancer patients.
The fact that MTA-1 expression in gastric cancer tissues is useful as a peritoneal dissemination predictor, and that the high expression of gastric cancer tissue ANGPTL 2 and the increase in ANGPTL 2 concentration in serum correlate with peritoneal dissemination and are useful for differentiation of poor prognosis group Indicated.
