Outline of Final Research Achievements |
We created cerebral infarction by use of rat middle cerebral artery occlusion and sampled the cerebral cortex, which was analyzed by metabolome analysis with the use of gas-chromatography/mass-spectrometry. The result implicated that the tricarboxylic acid cycle (TCA) cycle was stopped and that the anaplerotic responses such as malate-aspartate shuttle and purine nucleotide cycle were upregulated and that the pentose phosphate pathway (PPP) was also upregulated. Consequently, during ultra-acute stage of cerebral ischemia, it is most likely that TCA cycle was stopped due to ATP depletion and the anaplerotic responses was upregulated and PPP was upregulated to increase NADPH to deal with the reactive oxygen species.
