Figure 2. No significant difference in tissue selenium levels of Apoer2 ICD mutant mice from wild type.

Tissue selenium values were measured from mice of all six genotypes after four weeks on a 0.25 mg/kg selenium diet. Only Apoer2 KO mice presented with significantly lower selenium levels than wild type mice in the brain (A) and testes (B); **P<0.001. Liver selenium levels were comparable among all genotypes (C).
