Increased Iron Levels and Oxidative Stress Mediate Age-Related Impairments in Male and Female Drosophila melanogaster

Figure 7

GSH depletor (DEM) decreases GSH levels and negative geotaxis in 30-day-old males and females of Drosophila melanogaster. (a) Mortality caused by DEM after 24 h of exposure, (b) negative geotaxis, and (c) GSH levels. Results are represented as error (SEM) and are expressed (a) in number of dead flies, (b) number of flies on the top, and (c) per mmol GSH/mg of tissue. , , , and about their respective control (5-day-old male or 5-day-old female) and ##, ###, and #### in relation to the same group but without DEM and ^&& and ^&&&& about 5-day-old male with 5-day-old female with and without DEM.
