| Outline of Final Research Achievements |
In the cranial nervous system, many genes are regulated by RNA modification including splicing, and its breakdown can be a cause of developmental abnormality and neurological disorder. However, its molecular mechanism has not been elucidated. We analyzed the deficient mice of UPF1 gene which is a key component of the RNA surveillance and found that UPF1 is essential for maintenance of neural stem cells and normal nerve differentiation.
Furthermore, since the PI3K-AKT signal responsible for the phosphorylation control of UPF1 is closely related to brain function, we analyzed it using the diabetes model and Alzheimer's disease model which causes abnormality in this signal, we showed that the change in the phosphorylation of PI3K-AKT signal correlates with the progression of brain dysfunction.
