Expression of the Nrf2a target genes gstp, gsta1, gclc, ggt1b, and Nrf2b target p53 was examined using qPCR. For all genes, a dose-dependent increasing trend was observed in nrf2a mutant (m) embryos compared to wild-type (wt) embryos. Asterisks (*) indicate a dose-related change compared to genotypic controls. Daggers (†) indicate a change between wild-type and mutant embryos. α = 0.05. n=3-5 samples of 15 pooled embryos from 4 experimental replicates
