Expression of hepcidin1 (Hamp1) and hepcidin2 (Hamp2) in the liver of mice fed diets with different iron contents. The expression of hepcidin1 and hepcidin2 transcripts was assessed in mice of 2 strains (B6 and D2) fed an iron-deficient (ID), iron-balanced (IB), or iron-enriched (IE) diet. Expression levels were normalized to HPRT and log2 transformed, and are expressed as means of 5 samples plus or minus standard deviation. The contribution of diet was assessed by ANOVA, and statistical significant differences relative to the iron-balanced diet were determined by Scheffe posthoc tests. *P < .05; ***P < .001.
