| Research Abstract |
There is increasing evidence that neurodegenerative diseases are a symptom of a deficiency in the regulation of mitochondrial function and metabolism, however the mechanism has been unclear. Mitochondria, as the central organelles in metabolic regulation might have a role to play in the common etiology of neurodegeneration. To address the roles of metabolic defect in neurodegenerative diseases, we established RNA interference-mediated Drosophila parkin (dparkin) knockdown flies and Drosophila ALS2/alsin (dALS2) knockdown flies, for Parkinson's disease and juvenile onset recessive familial amyotrophic lateral sclerosis (ALS2) models, respectively. We demonstrate that nervous system-specific knockdown of dparkin or dALS2 caused shorter lifespan and lower locomotor activity. Currently we are exploring the relevance of abnormality of metabolism and mitochondrial dysfunction in neurodegenerative pathogenesis caused by deficiency of parkin or ALS2.
