15 صفحه اولEffect of Iron Overload and Iron Deficiency on Liver Hemojuvelin Protein
INTRODUCTION Hemojuvelin (Hjv) is a key component of the signaling cascade that regulates liver hepcidin (Hamp) expression. The purpose of this study was to determine Hjv protein levels in mice and rats subjected to iron overload and iron deficiency. METHODS C57BL/6 mice were injected with iron (200 mg/kg); iron deficiency was induced by feeding of an iron-deficient diet, or by repeated phleb...
متن کاملIron-Dependent Regulation of Hepcidin in Hjv−/− Mice: Evidence That Hemojuvelin Is Dispensable for Sensing Body Iron Levels
Hemojuvelin (Hjv) is a bone morphogenetic protein (BMP) co-receptor involved in the control of systemic iron homeostasis. Functional inactivation of Hjv leads to severe iron overload in humans and mice due to marked suppression of the iron-regulatory hormone hepcidin. To investigate the role of Hjv in body iron sensing, Hjv-/- mice and isogenic wild type controls were placed on a moderately low...
متن کاملIron Deficiency and Iron Overload.
Iron is essential to most, if not all, living organisms, and the higher animals and man have employed it for many purposes essential to life. The readiness with which iron undergoes oxidation and reduction is utilized in many of the enzymes of electron transport, and in a number of other enzymes whose function is not understood. Furthermore, the combination of iron with porphyrin and protein le...
متن کاملSkeletal muscle hemojuvelin is dispensable for systemic iron homeostasis.
Hepcidin, a hormone produced mainly by the liver, has been shown to inhibit both intestinal iron absorption and iron release from macrophages. Hemojuvelin, a glycophosphatidyl inositol-linked membrane protein, acts as a bone morphogenetic protein coreceptor to activate hepcidin expression through a SMAD signaling pathway in hepatocytes. In the present study, we show in mice that loss of hemojuv...
