Transient decrease of serum iron after acute erythropoietin treatment contributes to hepcidin inhibition by ERFE in mice

To coordinate iron supply with hemoglobin (Hb) synthesis, erythropoietin (EPO)-stimulated erythroid precursors release erythroferrone (ERFE), a soluble protein that suppresses the expression of hepcidin ( Hamp ).[1][1] Hepcidin is a short liver peptide that controls iron entry into the circulation
