Figure 8. Treatment and population effects on antioxidant gene expression in embryos from New Bedford Harbor (NBH) and Scorton Creek (SC).
The expression of catalase, gclc, gsta, nrf2, and sod2 were examined following acute exposure to DMSO (vehicle control), 5 µM or 10 µM tBHQ, or untreated water, at 7 dpf. Data presented are the mean ± SEM (β-actin-corrected) where N = 3 pools of five embryos. Values are normalized to those of untreated SC embryos. * denotes a significant effect of population in the two-factor ANOVA, and # indicates a significant treatment effect assessed by Fisher’s PLSD and Bonferroni-corrected, p < 0.0018
