Improvements of Paraquat Treatment in Liquid Media for Behavior and Neurodegenerative Tests.

Amyotrophic Lateral Sclerosis (ALS) is a disease characterized by misfolded and aggregated proteins that have toxic effects on motor neurons. The missense mutation, G85R, of the gene associated with ALS displays locomotor impairments in ( ). We treated the strain with 0 and 2.5 mM Paraquat treatments in a liquid M9 buffer for 4 hours and in solid NGM media for 18 hours. In both methodologies, the locomotion defects and neurodegeneration were significantly increased with 2.5 mM Paraquat. Our work provides evidence of methodology that is more cost effective, rapid and reproducible to perform behavior and neurodegenerative assay in worms.
