Outline of Final Research Achievements |
We examined the significance of accumulation of HIF (hypoxia-induced factor) and SDH (succinate dehydrogenase) in gastrointestinal stromal tumor (GIST). HIF-1α overexpression was correlated with worse prognosis. The expression level of miR-210, a target of HIF-1α was higher in high-grade GISTs. Therefore, HIF-1α accumulation and miR-210 overexpression may play an important role in the progression of GIST. In addition, in a subset of GIST, SDH deficiency may induce the accumulation of HIF-1α.
