We therefore compared the pituitary mRNA expression levels of β-TSH (measured by RT-PCR as a highly sensitive marker of thyroid function [ 20 ] by two-way ANOVA; the results showed a significant effect of the genotype (p = 0.011), a near-significant effect of iodide treatment (p = 0.066), and no interaction effect between genotype and treatment (p = 0.98), indicating that the Keap1 genotype does not modify the effect of iodide overload on thyroid function ( Fig. 3 C).
