Iron is an essential trace element whose absorption is usually tightly regulated in the duodenum. HFE-related hereditary hemochromatosis (HH) is characterized by abnormally low expression of the iron-regulatory hormone, hepcidin, which results in increased iron absorption. The liver is crucial for iron homeostasis as it is the main production site of hepcidin. The aim of this study was to explo...

OBJECTIVES Recent federal mandates and incentives have spurred the rapid growth, development and adoption of health information technology (HIT). While providing significant benefits for better data integration, organization, and availability, recent reports have raised questions regarding their potential to cause medication errors, decreased clinician performance, and lowered efficiency. The g...

Treatment for iron deficiency anemia can involve iron supplementation via dietary or parenteral routes that result in different cellular iron distributions. The effect of the administered iron on the iron regulatory system and hepcidin in the liver has not been well studied. Hepcidin, the liver-expressed central iron-regulatory peptide, is itself regulated through the bone morphogenetic protein...

BACKGROUND Mutations in HFE, a gene defect that can disrupt iron metabolism, have been implicated in increasing the risk of developing amyotrophic lateral sclerosis (ALS). OBJECTIVE To further establish the association between ALS and HFE mutations by investigating whether HFE mutations are associated with an increased risk of developing ALS in a population in The Netherlands and by pooling o...

OBJECTIVE To address the possibility that HFE mutations and TF gene polymorphism cause dysfunction of spermatogenesis and/or the hypothalamic-pituitary-gonadal axis via contribution to long-term iron overload in the testes and brain. DESIGN Case-control and association study. SETTING Clinic of obstetrics and gynecology and university-based research laboratory. PATIENT(S) 127 infertile men...

Regulation of iron homeostasis and the inflammatory response are tightly linked to protect the host from infection. Here we investigate how imbalanced systemic iron homeostasis in a murine disease model of hereditary hemochromatosis (Hfe(-/-) mice) affects the inflammatory responses of the lung. We induced acute pulmonary inflammation in Hfe(-/-) and wild-type mice by intratracheal instillation...

In this paper, we review and explain the existing algebraic cryptanalysis of multivariate cryptosystems from the hidden field equation (HFE) family. These cryptanalysis break cryptosystems in the HFE family by solving multivariate systems of equations. In this paper we present a new and efficient attack of this cryptosystem based on fast algorithms for computing Gröbner basis. In particular it ...

BACKGROUND AND OBJECTIVES Hereditary hemochromatosis (HC) is an inborn error of iron metabolism that leads to progressive iron overload. Considerable advances in the knowledge of molecular events in iron metabolism have been recently obtained. These molecular findings, the cloning of the gene responsible for HC (HFE gene) and the results of preliminary studies on the HFE protein prompted us to ...

OBJECTIVE To examine the relationship between iron status, hereditary hemochromatosis (HFE) gene mutations, and clinical features and outcomes of type 2 diabetes in a well-characterized representative sample of community-based patients. RESEARCH DESIGN AND METHODS HFE genotype data were available for 1,245 type 2 diabetic patients from the longitudinal observational Fremantle Diabetes Study (...

Hereditary hemochromatosis (HH) is a disorder of iron metabolism in which enhanced iron absorption of dietary iron causes increased iron accumulation in the liver, heart, and pancreas. Most individuals with HH are homozygous for a C282Y mutation in the HFE gene. The function of HFE protein is unknown, but it is hypothesized that it acts in association with beta(2)-microglobulin and transferrin ...
