Ironing out the problem: new mechanisms of iron homeostasis.
For most organisms, iron is an essential nutrient that is both difficult to acquire from the environment and toxic at high concentration. Therefore, to avoid deprivation or over-abundance of iron, bacteria and eukaryotes have developed a tight regulatory system to keep the metal within a narrow concentration range. Recent work in the bacteria Escherichia coli and in Pseudomonas aeruginosa has d...
متن کاملOut of Balance—Systemic Iron Homeostasis in Iron-Related Disorders
Iron is an essential element in our daily diet. Most iron is required for the de novo synthesis of red blood cells, where it plays a critical role in oxygen binding to hemoglobin. Thus, iron deficiency causes anemia, a major public health burden worldwide. On the other extreme, iron accumulation in critical organs such as liver, heart, and pancreas causes organ dysfunction due to the generation...
متن کاملIroning out the wrinkles in host defense: interactions between iron homeostasis and innate immunity.
Iron is an essential micronutrient for both microbial pathogens and their mammalian hosts. Changes in iron availability and distribution have significant effects on pathogen virulence and on the immune response to infection. Recent advances in our understanding of the molecular regulation of iron metabolism have shed new light on how alterations in iron homeostasis both contribute to and influe...
متن کاملIroning out cancer.
New insights into the roles of proteins that regulate cellular iron in cancer growth, angiogenesis, and metastasis have recently emerged. Discoveries of the roles of ferroportin, hepcidin, lipocalin 2, and members of the six transmembrane epithelial antigen of the prostate (STEAP) and iron regulatory protein (IRP) families in cancer have provided specificity and molecular definition to the role...
متن کاملIroning out Ferroportin.
Maintaining physiologic iron concentrations in tissues is critical for metabolism and host defense. Iron absorption in the duodenum, recycling of iron from senescent erythrocytes, and iron mobilization from storage in macrophages and hepatocytes constitute the major iron flows into plasma for distribution to tissues, predominantly for erythropoiesis. All iron transfer to plasma occurs through t...
