Bone Morphogenetic Protein Signaling Is Impaired in an Hfe Knockout Mouse Model of Hemochromatosis (original) (raw)

Background and Aims-Mutations in HFE are the most common cause of the iron-overload disorder hereditary hemochromatosis (HH). Levels of the main iron regulatory hormone, hepcidin, are inappropriately low in HH mouse models and patients with HFE mutations, indicating that HFE regulates hepcidin. The bone morphogenetic protein 6 (BMP6)-SMAD signaling pathway is an important endogenous regulator of hepcidin expression. We investigated whether HFE is involved in BMP6-SMAD regulation of hepcidin expression.
