Outline of Final Research Achievements

microRNAs (miRNAs) are a class of small, non-coding RNAs which mediate post-transcriptional regulation of gene expression. On the other hand, ischemic preconditioning involves numerous gene expression changes; however, its mechanism is still obscure. In this study, we evaluated the roles of miRNAs in ischemic preconditioning using rats and PC12 cells. Our results show that the expressions of a part of miRNAs were modified in the preconditioned brains or cells although further studies are necessary to clarify the relationship between miRNAs and gene expression changes.
