Effect of GE and AlkE on stress resistance of wild-type worms. (A) Survival rate of N2 (wt) worms under juglone-induced oxidative stress. Survival rate of N2 worms was significantly enhanced in the groups treated with 200 and 300 μg/mL of GE; no significant difference was observed among worms treated with AlkE and untreated worms. (B) Intracellular reactive oxygen species (ROS) accumulation in N2 (wt) worms after treatment with GE. ROS accumulation was significantly decreased by GE and AlkE treatment compared to the untreated control. The results are presented as mean ± SEM from three independent experiments. * p < 0.05, ** p < 0.01 *** p < 0.0001 compared to the untreated control by one-way analysis of variance (ANOVA) followed by Bonferroni’s method (post-hoc).
