Iron 95-99 hepcidin antimicrobial peptide Mus musculus 42-50 17241879-1 2007 BACKGROUND & AIMS: Hepcidin is a peptide hormone that is central to the regulation of iron homeostasis. Iron 90-94 hepcidin antimicrobial peptide Mus musculus 23-31 17241879-2 2007 In response to interleukin 6 (IL-6), hepatocytes produce hepcidin that decreases iron release/transfer from enterocytes and macrophages and causes hypoferremia.

Iron 25-29 hepcidin antimicrobial peptide Mus musculus 0-8 17207112-2 2007 The liver-derived peptide hepcidin is the central regulator of iron homeostasis and recent animal studies have demonstrated that exposure to alcohol reduces hepcidin expression. Iron 63-67 hepcidin antimicrobial peptide Mus musculus 26-34 17207112-3 2007 This down-regulation of hepcidin in vivo implies that disturbed iron sensing may contribute to the hepatosiderosis seen in alcoholic liver disease. Iron 64-68 hepcidin antimicrobial peptide Mus musculus 24-32 16902156-1 2006 Hepcidin is the presumed negative regulator of systemic iron levels; its expression is induced in iron overload, infection, and inflammation, and by cytokines, but is suppressed in hypoxia and anemia.

Iron 133-137 hepcidin antimicrobial peptide Mus musculus 32-40 16882706-4 2006 The suppression of hepcidin necessary to match iron supply to erythropoietic demand thus requires increased erythropoiesis and is not directly mediated by anemia, tissue hypoxia, or erythropoietin. Iron 47-51 hepcidin antimicrobial peptide Mus musculus 19-27 16939499-2 2006 In a mouse model of beta-thalassaemia, we observed that the liver expressed relatively low levels of hepcidin, which is a key factor in the regulation of iron absorption by the gut and of iron recycling by the reticuloendothelial system. Iron 188-192 hepcidin antimicrobial peptide Mus musculus 101-109 16574947-3 2006 At that time, although the role of USF2 was still confounding, we proposed for the first time the role of hepcidin as a negative regulator of iron absorption and iron release from macrophages. Iron 142-146 hepcidin antimicrobial peptide Mus musculus 106-114 16648237-10 2006 These findings are consistent with the current model that HAMP production leads to a decreased iron efflux. Iron 95-99 hepcidin antimicrobial peptide Mus musculus 58-62 16648237-11 2006 Our studies suggest that iron mobilization by alveolar macrophages can be affected by iron and LPS via several pathways, including HAMP-mediated degradation of FPN1, and that these cells may use unique regulatory mechanisms to cope with iron imbalance in the lung.

Iron 175-179 hepcidin antimicrobial peptide Mus musculus 30-35 16574947-3 2006 At that time, although the role of USF2 was still confounding, we proposed for the first time the role of hepcidin as a negative regulator of iron absorption and iron release from macrophages. Iron 162-166 hepcidin antimicrobial peptide Mus musculus 106-114 16574947-6 2006 Confirming our prior results, Hepc1(-/-) mice developed early and severe multivisceral iron overload, with sparing of the spleen macrophages, and demonstrated increased serum iron and ferritin levels as compared with their controls.

Iron 36-40 hepcidin antimicrobial peptide Mus musculus 0-8 16565419-1 2006 Hepcidin is a negative regulator of iron absorption produced mainly by the liver in response to changes in iron stores and inflammation, and its levels have been shown to regulate the intestinal basolateral iron transporter ferroportin1 (Fp1). Iron 107-111 hepcidin antimicrobial peptide Mus musculus 0-8 16928320-0 2006 [An iron regulator hepcidin is affected by EPO]. Iron 4-8 hepcidin antimicrobial peptide Mus musculus 19-27 16801541-1 2006 Recently, it has been suggested that hepcidin, a peptide involved in iron homeostasis, is regulated by bone morphogenetic proteins (BMPs), apparently by binding to hemojuvelin (Hjv) as a coreceptor and signaling through Smad4. Iron 69-73 hepcidin antimicrobial peptide Mus musculus 37-45 16755567-6 2006 In our work, we measured by RQ-PCR the liver mRNA expression of hepcidin and other iron regulatory genes in beta-thalassemia major mouse model (C57Bl/6 Hbb(th3/th3)), and compared it with beta-thalassemia intermedia mouse model (C57Bl/6 Hbb(th3/+)) and control mice. Iron 83-87 hepcidin antimicrobial peptide Mus musculus 64-72 16755567-8 2006 Significant down-regulation of hepcidin expression in beta-thalassemia major, despite iron overload, might explain the increased iron absorption typically observed in thalassemia. Iron 86-90 hepcidin antimicrobial peptide Mus musculus 31-39 16755567-8 2006 Significant down-regulation of hepcidin expression in beta-thalassemia major, despite iron overload, might explain the increased iron absorption typically observed in thalassemia.

Iron 83-87 hepcidin antimicrobial peptide Mus musculus 8-16 16332970-2 2006 Hepcidin is an acute-phase protein with specific iron regulatory properties, which, along with the anemia seen with increased hepcidin expression, have led many to consider it the major mediator of ACD. Iron 49-53 hepcidin antimicrobial peptide Mus musculus 0-8 16332970-6 2006 These studies suggest that hepcidin may contribute to anemia in ACD not only through effects on iron metabolism, but also through inhibition of erythroid progenitor proliferation and survival. Iron 96-100 hepcidin antimicrobial peptide Mus musculus 27-35 16418170-4 2006 A significant delay in developmental up-regulation of hepcidin (Hamp), the pivotal hormonal regulator of iron homeostasis, correlated with high levels of Fpn1 expression in hepatic Kupffer cells and duodenal epithelial cells at 7 weeks of age. Iron 105-109 hepcidin antimicrobial peptide Mus musculus 54-62 16418170-4 2006 A significant delay in developmental up-regulation of hepcidin (Hamp), the pivotal hormonal regulator of iron homeostasis, correlated with high levels of Fpn1 expression in hepatic Kupffer cells and duodenal epithelial cells at 7 weeks of age. Iron 105-109 hepcidin antimicrobial peptide Mus musculus 64-68 16418170-6 2006 Hamp regulation due to iron did not appear dependent on transcription-level changes of the murine homolog of Hemojuvelin (Rgmc). Iron 23-27 hepcidin antimicrobial peptide Mus musculus 0-4 16418170-8 2006 Thus, similar to the anemia of chronic disease, these findings demonstrate decreased iron bioavailability due to sustained down-regulation of Fpn1 levels by Hamp.

Iron 131-135 hepcidin antimicrobial peptide Mus musculus 82-90 16339398-3 2006 This clearly establishes the key role of hepcidin in regulating the extracellular iron concentration. Iron 82-86 hepcidin antimicrobial peptide Mus musculus 41-49 16339398-4 2006 We previously demonstrated that, when expressed early in fetal development, constitutive transgenic hepcidin expression prevented iron accumulation in an Hfe-/- mouse model of hemochromatosis.

Iron 18-22 hepcidin antimicrobial peptide Mus musculus 50-58 29498084-4 2018 Hepcidin induction by RNAi-mediated inhibition of TMPRSS6 expression reduces iron overload and mitigates anemia in murine models of beta-thalassemia intermedia. Iron 77-81 hepcidin antimicrobial peptide Mus musculus 0-8 29543343-1 2018 OBJECTIVE: During hypoxia, hepcidin expression is inhibited to allow iron mobilization to sustain erythropoietic expansion. Iron 69-73 hepcidin antimicrobial peptide Mus musculus 27-35 29575577-1 2018 To maintain iron homoeostasis, the iron regulatory hormone hepcidin is tightly controlled by BMP-Smad signalling pathway, but the physiological role of Smad7 in hepcidin regulation remains elusive.
