| Outline of Final Research Achievements |
We explored cerebral infarction using a model mouse with an operation of middle cerebral artery occlusion (MCAO) and screened the genes which expressions were altered between the normal and infarct sides in the cerebral cortex two hours after MCAO by RNA sequencing. We narrowed down 27 genes whose expressions were increased in the border of the infarct site compared with the control by ISH. Among these, the neural activity-dependent transcription factor Npas4 showed conspicuous expression in excitatory neurons of the cerebral cortex and the expression pattern that go along the border of the infarct site. Further analyses suggested that Npas4 and its regulating genes play crucial roles in rebuilding the neural circuitry via promoting the neuronal development and survival in the healthy and diseased brain, respectively.
