| Outline of Final Research Achievements |
We performed transcriptomic analysis and comprehensively analyzed the expression changes of messenger RNA (mRNA) in the brain, especially in the hippocampus due to surgery and anesthesia stress. Furthermore, we identified the all expression genes that increased or decreased by surgery and anesthesia stress, and also found that the expression of a specific gene changes in conjunction with the deterioration of cognitive function examined in the Burns Maze test.
In this study, we were able to elucidate a part of the mechanism of post oeprative cognitive dysfunction (POCD), and clarify the specify mRNA as a marker that could predict the onset of cognitive dysfunction.
And, we believe that the information provided from this research will bring significant meaning to future research.
