| Outline of Final Research Achievements |
We investigated whether volatile anesthetics caused postoperative cognitive dysfunction (POCD). In humans, desflurane anesthesia showed a better mini mental examination score than did sevoflurane anesthesia. However, we could not find any genetic polymorphisms associated with cognitive function in humans. To examine the association between general anesthesia and POCD, we investigated whole mRNA expression in mouse hippocampal cells by a transcriptome-wide association study. While expression of the Lhx9 gene was suppressed by exposure to volatile anesthetics in juvenile mice, expression of Lhx9 gene was greatly enhanced by exposure to volatile anesthetics in adult mice. These results suggest that volatile anesthetics affect the differentiation of stem cells in the mouse hippocampus, and the results should be useful for exploring biomarkers of POCD.
