(A) WT and Zip14−/− mice were administered LPS (2 mg/kg or saline 0.5 mL; ip), 18 hr before being killed. (A) Serum and liver iron concentrations were measured by AAS. Liver non-heme-iron was measured colorimetrically. (B) Fasted WT and Zip14−/− mice received 2 µCi of 59Fe by gavage and were killed 24 hr later. Percent absorption was calculated from the radioactivity administered. Serum and liver iron uptake was calculated from the specific activity of the 59Fe. (C) Transcript abundance for liver hepcidin, TfR-1, DMT1 and ferritin was measured by qPCR and expressed relative to TBP mRNA as the normalizer. Values are mean ± SE, n = 5−10.
