| Outline of Final Research Achievements |
Based on the analysis result of RUNX3 knockout mouse as well as clinical samples of gastric cancer, the following was developed aiming at the functional analysis of RUNX3, and gene diagnosis and the application to carcinogenic prevention and medical treatment. We have already identified several kinds of markers of a gastric cancer precursor cell, and are looking for a stomach cancer precursor cell in the background membrane of an early frequent occurrence stomach cancer excision specimen. Furthermore, RUNX3 has played the role important for TGFbeta dependence apoptosis, and participating in the susceptibility of a radiation chemistry treatment became clear (Oncogene, Sakakura et al., 2007).
With Luminex system, we establish the quick serological-diagnosis system which can measure quantitatively methylation of two or more genes in many samples in a short time, and are trying for clinical application.
