hepcidin


Also found in: Wikipedia.
A 25-residue peptide hormone encoded by the HAMP gene, produced by the liver, and now regarded as the master regulator of iron homeostasis in humans and other mammals. Hepcidin is a direct inhibitor of ferroportin, a protein present in enterocytes and macrophages, which transports iron out of cells and into storage pools

hepcidin

(hĕp′sĭd-ĭn)
A protein secreted by the liver that acts as a regulatory hormone that controls the amount of iron in the body. Elevated levels of hepcidin in the blood prevent iron from being taken up by red blood cells. Hepcidin levels rise in many chronic illnesses and infections, causing the anemia of chronic disease. Proteins that block the action of hepcidin result, by contrast, in iron overload diseases such as hemochromatosis.

Newer tests such as soluble transferrin receptor (sTfR), sTfR/ log ferritin ratio, hepcidin, percentage of hypochromic red blood cells (%HRC) and reticulocyte haemoglobin content (CHr) can distinguish ACD from IDA, and can identify combined ACD and IDA.
Aims and Objectives: Our objective was to demonstrate whether curcumin treatment could attenuate the effect of recombinant human EPO on erythropoiesis in EPO-induced polycythemia, and if so, whether this effect is mediated by changing concentrations of iron and its key regulator hormone hepcidin in rats.

Elevated serum levels of hepcidin increases the breakdown of iron transporter protein, ultimately inhibiting iron uptake.
