Figure 1. Regulation of HAMP expression in the cell. BMP/SMAD and JAK2/STAT3 signaling pathways regulate the expression of HAMP.
HAMP, hepcidin; BMP, bone morphogenetic protein; BMPR, bone morphogenetic protein receptor; SMAD, small-mothers-against-decapentaplegic protein; JAK2, Janus kinase 2; STAT3, signal transducer and activator of transcription 3; HFE, homeostatic iron regulator; HJV, hemojuvelin; holo-Tf, diferric-transferrin; IL-6, interleukin-6; IL-6R, interleukin-6 receptor; TfR, transferrin receptor.
