The main objective of our laboratory is to understand the molecular and cellular basis of the motor system and the pathology of amyotrophic lateral sclerosis (ALS), an incurable motor neuron disease. Using zebrafish as a primary model, we study the motor system at the behavioral, circuit, cellular, and molecular levels, with a primary focus on synapse formation, phase separation, RNA metabolism, energy homeostasis, DNA damage, and ploidy. The ultimate goal is to identify the root causes of ALS and develop therapeutic strategies through comprehensive and multidimensional basic research.
