| Outline of Final Research Achievements |
The goal of current study was to elucidate the mitochondrial vital response with brain ischemia, and to develop a novel forensic brain function biomarker using its vital response. Here, we examined the relationship between mitochondrial function and morphology using the brain ischemia model neurons. Under ischemic conditions, cell respiratory and mitochondrial activities significantly decreased in comparison with normoxic conditions. With their decrease in cellular functions, mitochondria were altered to simple filamentous and granular patterns from its complex fibrous structures. In addition, mitochondrial morphological changes were also retained in fixative specimens as a vital reaction. These results indicated that mitochondrial morphology would be a useful forensic biomarker of brain ischemia.
