FIG. 1.
Prolonged lifespan in oxidative stress. (A) Three- to five-day-old adult flies were exposed to 90% O2 and percent survival was scored daily. Adult hyperoxia selected (SO2A) flies exhibited a significantly better survival in 90% O2 as compared to control flies and a 25% increase in median and maximum lifespan respectively (p<0.01). (B) Three- to five-day-old adult flies were exposed to 15 mM paraquat and percent survival was scored every 8–16 h. A greater survival rate was observed in adult SO2A flies as compared to control flies (86% vs. 46%) after 48 h of paraquat treatment (p<0.01).
