Reactive oxygen species (ROS) are common by-products generated mostly in mitochondria. Excess ROS cause biomolecule damage and will further lead to neurodegeneration. Many neurodegenerative diseases like Alzheimer's disease, Parkinson's disease, multiple sclerosis and amyotrophic lateral sclerosis are exacerbated by ROS. Oxidative stress due to ROS also contributes to aging, a major risk factor for neurodegenerative diseases. By feeding fruit flies with paraquat, a poison known to increase ROS, we can screen mutants for sensitivity to ROS. This systemic screen allows us to address the cellular mechanisms involved in the response to ROS and increase and assess their contribution to neurodegeneration.
