| Outline of Final Research Achievements |
In this study, we investigated the molecular mechanism of audiogenic seizure observed in eEF1BdeltaL knockout (KO) mouse. We found that epilepsy-related gene Cacna1a was significantly decreased in the brain of eEF1BdeltaL KO mice. Furthermore, induction of molecular chaperones was suppressed in the brain of these mice. After auditory stress, the brain atrophy was observed in KO mice. Molecular chaperones protect cells from various stresses. Our study suggests that eEF1BdeltaL might function as a safeguard against excessive response to environmental stress and gives new insight into molecular mechanism of stress-related psychiatric disorders.
