AI Article Synopsis
- Hepcidin production is regulated by various factors like iron levels, anemia, and low oxygen, and this study specifically looks at thalassemia major patients.
- Hepcidin mRNA levels in the liver were positively linked to hemoglobin levels, while inversely linked to factors like serum transferrin receptor and non-transferrin-bound iron.
- The results suggest that hepcidin regulation is primarily influenced by increased red blood cell production rather than just iron overload, highlighting its crucial role in controlling iron balance and toxicity in thalassemia patients.
Article Abstract
Hepcidin production is homeostatically regulated by iron stores, anemia and hypoxia. We evaluated the effect of iron overload and of ineffective erythropoeisis on hepcidin expression in patients with thalassemia major. Liver hepcidin mRNA levels correlated with hemoglobin concentration and inversely correlated with serum transferrin receptor, erythropoietin and non-transferrin-bound iron. They did not correlate with indices of iron load. Urinary hepcidin levels were disproportionably suppressed in regards to iron burden. We conclude that hepcidin expression is regulated mainly by increased erythropoietic activity rather than by iron load and that hepcidin plays a central regulatory role in iron circulation and iron toxicity in patients with thalassemia.

Assessment of a Novel Stress and Immune Gene Panel on the Development of Australasian Snapper () Larvae.
Genes (Basel)
November 2024
The New Zealand Institute for Plant and Food Research Limited, Private Bag 11600, Palmerston North 4442, New Zealand.
Background: Larvae development is a critical step in aquaculture, yet the development of immune and stress responses during this early phase of life is not well understood. Snapper is a species that has been selected as a candidate for aquaculture in New Zealand.
Methods: In this study we explore a set of 18 genes identified as potentially being involved in the stress and immune responses of snapper larvae during the first 30 days of development.
Iron-Mediated Regulation in Adipose Tissue: A Comprehensive Review of Metabolism and Physiological Effects.
Curr Obes Rep
January 2025
Department of Endocrinology and Metabolism, Zhuhai People's Hospital (The Affiliated Hospital of Beijing Institute of Technology, Zhuhai Clinical Medical College of Jinan University), Zhuhai, China.
Purpose Of Review: Review the latest data regarding the intersection of adipose tissue (AT) and iron to meet the needs of AT metabolism and the progression of related diseases.
Recent Findings: Iron is involved in fundamental biological metabolic processes and is precisely fine-tuned within the body to maintain cellular, tissue and even systemic iron homeostasis. AT not only serves as an energy storage depot but also represents the largest endocrine organ in the human body, maintaining systemic metabolic homeostasis.

Iron is one of the indispensable trace elements in living organisms. However, excessive iron deposition in organisms is prone to induce dysfunction of the liver and other vital organs. The present study aimed to investigate the mechanism how aquatic high iron affects iron transport and induces hepatic injury in zebrafish.

Background: Hepcidin, a peptide hormone primarily produced by the liver, regulates iron metabolism by interacting with its receptor, ferroportin. Studies have demonstrated that hepcidin participates in the progression of liver fibrosis by regulating HSC activation, but its regulatory effect on hepatocytes remains largely unknown.
Methods: A carbon tetrachloride (CCl4)-induced liver fibrosis model was established in C57BL/6 wild-type (WT) and hepcidin knockout (Hamp-/-) mice.
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 PAH pathogenesis. However, the role of human pulmonary artery endothelial cells (PAECs) as either a source of hepcidin, or the effect of hepcidin on PAEC function is not as well described.
