Fig. 4 Fig. 4. Effect of two weeks exposure to 0.3 and 3 μg/L glyphosate on the antioxidant status and lipid peroxidation levels in the brain of adult zebrafish. Whereas catalase and superoxide dismutase (SOD) activities increased, the gamma-glutamate cysteine ligase (γ-GCL) activity was strongly inhibited in the brain of glyphosate-treated fish. Moreover, total glutathione stores decreased and lipid peroxidation levels increased in the treated fish. Data reported as scatter plot with the median. *P < 0.05, **P < 0.01, ***P < 0.001; one-way ANOVA with Dunnett’s multiple comparison test (catalase, γ-GCL, GSx) or Kruskal Wallis test with Bonferroni correction (SOD, LPO). Data from 2 independent experiments (n = 11–13).
