| Outline of Final Research Achievements |
Glycogen is formed from glucose and its metabolism is known to play a role in energy supply. In this study, we focused on Glycogenin (Gyg), which is the core enzyme of glycogen synthesis, and analyzed its role in the brain development. When we examined the expression of the Gyg gene in the cerebral cortex, it was strongly expressed in the neural stem cells. We introduced knockdown construct by in utero electroporation, and found that differentiation and migration of neurons were disturbed. We further established Gyg KO mice using Crispr/Cas9 method. However, Gyg KO mice showed early postnatal lethality and showed similar abnormality in cortical layer formation.
From these observation, it was suggested that the glycogen metabolic pathway is important for the development of the cerebral cortex.
