Hepcidin Assays [PDF]

Clinical Journal of the American Society of Nephrology, 2009
Iron is the fourth most common element in the earth's crust and the most abundant transition metal in the human body. It is an essential element required for growth and survival. Maintaining the correct iron balance is crucial for health. All living organisms evolved sophisticated mechanisms to maintain appropriate iron levels in their cells and within

Comparisons Between Serum Levels of Hepcidin and Leptin in Male College-Level Endurance Runners and Sprinters

Frontiers in Nutrition, 2021
Background: Hepcidin-25 is a 25 amino acid hepatokine and a key regulator of iron metabolism related to iron deficiency anemia. Recent studies have suggested that an elevated hepcidin level is correlated with low energy availability.

Hemojuvelin-Neogenin Interaction Is Required for Bone Morphogenic Protein-4-induced Hepcidin Expression [PDF]

, 2009
Hemojuvelin (HJV) is a glycosylphosphatidylinositol-linked protein and binds both bone morphogenic proteins (BMPs) and neogenin. Cellular HJV acts as a BMP co-receptor to enhance the transcription of hepcidin, a key iron regulatory hormone secreted ...

A tincture of hepcidin cures all: the potential for hepcidin therapeutics [PDF]

Journal of Clinical Investigation, 2010
Iron overload as a result of blood transfusions and excessive intestinal iron absorption can be a complication of chronic anemias such as β-thalassemia. Inappropriately low levels of hepcidin, a negative regulator of iron absorption and recycling, underlie the pathophysiology of the intestinal hyperabsorption. In this issue of the JCI, Gardenghi et al.

Proteinvermittelte Kupfer‐Redoxregulation: Rolle von Disulfidbrücken und allosterischer Modulation

Angewandte Chemie, EarlyView.
Copper binding triggers structural changes that expose a reactive disulphide bridge, enabling intrinsic Cu(II) reduction in folded proteins. SAXS, XAS, and QM/MM simulations reveal how globular proteins such as HSA and SOD1 employ disulphide‐mediated dynamics to modulate site accessibility and control copper redox chemistry.

Hepatic heparan sulfate is a master regulator of hepcidin expression and iron homeostasis in human hepatocytes and mice. [PDF]

, 2019
Hepcidin is a liver-derived peptide hormone that controls systemic iron homeostasis. Its expression is regulated by the bone morphogenetic protein 6 (BMP6)/SMAD1/5/8 pathway and by the proinflammatory cytokine interleukin 6 (IL6).

Protein‐Driven Copper Redox Regulation: Uncovering the Role of Disulphide Bonds and Allosteric Modulation

Angewandte Chemie International Edition, EarlyView.
Copper binding triggers structural changes that expose a reactive disulphide bridge, enabling intrinsic Cu(II) reduction in folded proteins. SAXS, XAS, and QM/MM simulations reveal how globular proteins such as HSA and SOD1 employ disulphide‐mediated dynamics to modulate site accessibility and control copper redox chemistry.

Evaluating Transcriptomic Biomarkers for rHuEPO Detection: Assessing the Impact of Exercise and Altitude Exposure

Drug Testing and Analysis, EarlyView.
A two‐stage transcriptomic filter comparing rHuEPO, exercise and altitude responses reduced 153 candidate genes to 50 that were unaffected by physiological stimuli. These retained transcripts offer focused biomarker leads to strengthen antidoping detection of rHuEPO.

The hepcidin‐ferroportin axis influences mitochondrial function, proliferation, and migration in pulmonary artery endothelial and smooth muscle cells

Pulmonary Circulation
Elevated circulating hepcidin levels have been reported in patients with pulmonary artery hypertension (PAH). Hepcidin has been shown to promote proliferation of human pulmonary artery smooth muscle cells (PASMCs) in vitro, suggesting a potential role in

Serum Hepcidin Levels and Reticulocyte Hemoglobin Concentrations as Indicators of the Iron Status of Peritoneal Dialysis Patients

International Journal of Nephrology, 2012
Hepcidin is the key mediator of renal anemia, and reliable measurement of serum hepcidin levels has been made possible by the ProteinChip system. We therefore investigated the iron status and serum hepcidin levels of peritoneal dialysis (PD) patients who
