Description

This study investigates the age-related locomotor impairment caused by reactive oxygen species (ROS), a common byproduct of mitochondrial energy metabolism, which can also be induced by exogenous sources, including UV light, radiation, and environmental toxins. Here, the authors assessed the locomotion of aged flies on standard medium and following chronic exposure to medium supplemented with 3 mM menadione sodium bisulfite (MSB), as a proxy for ROS-induced locomotor decline.

Comments from curator

Phenotyping data were extracted from Table S1 in the Supporting information section.

For the geotaxis assay, each fly received a score for the highest point reached during the assay period according to 26 divisions of 5mm each so that scores ranged from 0 to 26.

Startle responses were quantified by subjecting each fly to a mechanical disturbance by tapping the vial twice against a surface and recording the amount of time the fly is active in the 45-second period immediately following the disturbance. The authors used a block-design and corrected accordingly the raw data for block effects.
