Mice have been essential for distinguishing the role of hepcidin in iron
homeostasis. Currently, investigators monitor levels of murine hepatic hepcidin-1
mRNA as a surrogate marker for the bioactive hepcidin protein itself. Here, we
describe and validate a competitive, enzyme-linked immunosorbent assay that
quantifies hepcidin-1 in mouse serum and urine. The assay exhibits a biologically
relevant lower limit of detection, high precision, and excellent linearity and
recovery. We also demonstrate correlation between serum and urine hepcidin-1
values and validate the competitive enzyme-linked immunosorbent assay by
analyzing plasma hepcidin response of mice to physiological challenges, including
iron deficiency, iron overload, acute blood loss, and inflammation. Furthermore,
we analyze multiple murine genetic models of iron dysregulation, including
?-thalassemia intermedia (Hbb(th3/+)), hereditary hemochromatosis (Hfe(-/-),
Hjv(-/-), and Tfr2(Y245X/Y245X)), hypotransferrinemia (Trf(hpx/hpx)),
heterozygous transferrin receptor 1 deficiency (Tfrc(+/-)) and iron refractory
iron deficiency anemia (Tmprss6(-/-) and Tmprss6(hem8/hem8)). Novel compound iron
metabolism mutants were also phenotypically characterized here for the first
time. We demonstrate that serum hepcidin concentrations correlate with liver
hepcidin mRNA expression, transferrin saturation and non-heme liver iron. In some
circumstances, serum hepcidin-1 more accurately predicts iron parameters than
hepcidin mRNA, and distinguishes smaller, statistically significant differences
between experimental groups.
