Figure 7. mRNA levels of heme oxygenase-1 (Ho-1, top) and early growth response protein-1 (Egr1) in Nrf2-null, wild-type and Keap1-HKO mice administered saline (10 ml/kg, i.p.) or microcystin (50 μg/kg, i.p.).

Values are expressed as mean ± S.E.M. (n = 8). *significantly different from the basal level of the same genotype (p ≤ 0.05); #significantly different from Nrf2-null mice treated with microcystin (p ≤ 0.05).
