The Importance Of Iron In Pathophysiologic Conditions
The iron element (Fe) is strictly required for the survival of most forms of life, including bacteria, plants and humans. Fine-tuned regulatory mechanisms for Fe absorption, mobilization and recycling operate to maintain Fe homeostasis, the disruption of which leads to Fe overload or Fe depletion. Whereas the deleterious effect of Fe deficiency relies on reduced oxygen transport and diminished activity of Fe-dependent enzymes, the cytotoxicity induced by Fe overload is due to the ability of this metal to act as a pro-oxidant and catalyze the formation of highly reactive hydroxyl radicals via the Fenton chemistry. This results in unfettered oxidative stress generation that, by inducing protei...
Iron as Therapeutic Targets in Human Diseases
Iron is an essential element for almost all organisms, a cofactor playing a crucial role in a number of vital functions, including oxygen transport, DNA synthesis, and respiration. However, its ability to exchange electrons renders excess iron potentially toxic, since it is capable of catalyzing the formation of highly poisonous free radicals. As a consequence, iron homeostasis is tightly controlled by sophisticated mechanisms that have been partially elucidated. Because of its biological importance, numerous disorders have been recently linked to the deregulation of iron homeostasis, which include not only the typical disorders of iron overload and deficiency but also cancer and neurodegene...
Protein Sensors and Reactive Oxygen Species
This volume of Methods in Enzymology is a companion to Volume 347 and addresses direct sensing of reactive oxygen species and related free radicals by thiol enzymes and proteins.
Nitric Oxide
Nitric oxide (NO) is a gas that transmits signals in an organism. Signal transmission by a gas that is produced by one cell and which penetrates through membranes and regulates the function of another cell represents an entirely new principle for signaling in biological systems. NO is a signal molecule of key importance for the cardiovascular system acting as a regulator of blood pressure and as a gatekeeper of blood flow to different organs. NO also exerts a series of other functions, such as acting a signal molecule in the nervous system and as a weapon against infections. NO is present in most living creatures and made by many different types of cells. NO research has led to new treatment...
Protein Sensors and Reactive Oxygen Species, Part B: Thiol Enzymes and Proteins
This volume of Methods in Enzymology is a companion to Volume 347 and addresses direct sensing of reactive oxygen species and related free radicals by thiol enzymes and proteins.
Cellular and Molecular Biology of Metals
With chapter contributions from more than 30 metal biology experts, Cellular and Molecular Biology of Metals explains the role of key divalent metal ions involved in the molecular and cellular biology of various target cell populations. Although it primarily focuses on homeostatic metals, such as nickel, zinc, and chromium, the text also discusses
Iron Metabolism
Iron plays a crucial role in many biochemical processes. In recent years intensive research has led to a better understanding of the function of iron in cellular metabolism. In more than twenty articles internationally renowned experts give a thorough account of the recent developments of this fascinating field. The book focuses on the central questions, e.g. transport, storage, and utilization of iron in cells, the three-dimensional structure of iron-containing proteins, the physiological function of heme and iron sulfur-containing proteins, and the regulatory mechanisms in heme biosynthesis and redox regulation of signal transduction. The interdisciplinary character of the book is designed to explore the many facets of the new findings and to provide a comprehensive overview of recent advances for biochemists, bioinorganic chemists, molecular biologists, microbiologists and immunologists. The reviews are supplemented with valuable background information, results and numerous references. This book emphasizes the relationships between the different disciplines concerned with iron metabolism and opens new perspectives for future research!
