The key role of histone deacetylases (HDAC) in the regulation of the cellular response to infection with the hepatitis C virus (HCV) was first demonstrated in 2008. When studying the metabolism of iron in the liver tissues of patients with chronic hepatitis C, the authors found that the expression of the hepcidin gene (HAMP), a hormone regulator of iron export, is markedly reduced in hepatocytes under conditions of oxidative stress caused by viral infection. HDAC were involved in the regulation of hepcidin expression through the control of acetylation level of histones and transcription factors, primarily STAT3, associated with the HAMP promoter. The purpose of this review was to summarize current data on the functioning of the HCV-HDAC3-STAT3-HAMP regulatory circuit as an example of a well-characterized interaction between the virus and the epigenetic apparatus of the host cell.

Background And Aims: Chronic apical periodontitis (CAP), an inflammatory disease of the oral cavity caused by bacterial infections with Porphyromonas gingivalis (P. gingivalis) as a key pathogen, has been associated with systemic effects, potentially influencing distant organs including liver. The liver plays a key role in iron metabolism and immunity by hepcidin.

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.

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.
