| Outline of Final Research Achievements |
A nuclear protein, TDP-43, accumulates in the cytoplasmic inclusions in the sporadic ALS lesions with post-transcriptional modifications, such as ubuiquitination, phosphorylation and truncation, and it works as a pathologic protein of the disease. Motor neurons, target cells of ALS, are highly sensitive to stress in the ER, which is the specialized organelle for folding and maturation of membrane and secretory proteins. I observed that the integrated responses against ER stress is increased in the HeLa cells lacking TDP-43. Comprehensive analysis revealed that a protein, which may regulate ER homeostasis, is drastically down-regulated in the TDP-43-deficient cells. In addition, I performed immune histological examination using the cerebral cortices which was transfected with the TDP-43 regulated gene by in utero electroporation.
