Outline of Final Research Achievements |
Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease that is characterized by degeneration of motor neurons in the brain and spinal cord. The molecular mechanisms of ALS have not been clarified. To investigate the mechanisms of ALS-induced neuronal dysfunction in vivo, we employed Drosophila TDP43- or Drosophila FUS- knockdown ALS models for suitable genetic-screening. As a result, we successfully identified new some genes that are involved in both ALS model flies. And, mutation in EGFR pathway-related genes rescued the Drosophila FUS-knockdown induced rough-eye phenotype; fusion of cone cells and ommatidia. Our findings suggest that Drosophila FUS negatively regulates the EGFR signaling pathway.
