As the power house of cells, mitochondria play the essential role in keeping the stabilization of brain energy metabolism. However, the mitochondrial DNA (mtDNA) is a vulnerable target of irradiation, the injury of mtDNA might be the root of RBI. Here we investigted the mtDNA injury and the cerebral ischemia induced by carbon ions or X-rays. The long PCR results indicated that both carbon ions and X-rays caused the mtDNA injury and upregulated the expression of HIF-1arufa. The mtDNA injury and expression of HIF-1arufa maintained in high level in carbon ions irradiated group, whereas they recovered to the control level in X-rays irradiated group which indicated that the injury induced by carbon ions is more difficult to repair in brain tissue., 平成23年度HIMAC共同利用研究成果発表会}, title = {Mitochondrial dysfunction induced by heavy-ion radiation in mouse brain: Does hypoxia play a role?}, year = {2012} }
