Outline of Final Research Achievements

In the present research, we investigated the function of candidate tumor suppressor gene, RIZ in oral squamous cell carcinoma (OSCC). According to our gene analysis, no frameshift mutation but two polymorphisms were detected. There was no significant relation between any of the two polymorphisms and clinicopathological data or patient’s survival for OSCC. According to the immunohistochemistry by using anti-RIZ antibody, RIZ protein were expressed in not only OSCC but also precancerous lesion. It was suggested that RIZ protein played an important role in the carcinogenesis of OSCC, especially related at late stage.
