Retinal iron homeostasis in health and disease
Iron is essential for life, but excess iron can be toxic. As a potent free radical creator, iron generates hydroxyl radicals leading to significant oxidative stress. Since iron is not excreted from the body, it accumulates with age in tissues, including the retina, predisposing to age-related oxidative insult. Both hereditary and acquired retinal diseases are associated with increased iron leve...
متن کاملIron Homeostasis in Health and Disease
Iron is required for the survival of most organisms, including bacteria, plants, and humans. Its homeostasis in mammals must be fine-tuned to avoid iron deficiency with a reduced oxygen transport and diminished activity of Fe-dependent enzymes, and also iron excess that may catalyze the formation of highly reactive hydroxyl radicals, oxidative stress, and programmed cell death. The advance in u...
متن کاملIron transport & homeostasis mechanisms: their role in health & disease.
Iron is an essential trace metal required by all living organisms and is toxic in excess. Nature has evolved a delicately balanced network to monitor iron entry, transport it to sites of need, and serve as a unique storage and recycling system, in the absence of an excretory system, to remove excess iron. Due to the unique nature of iron metabolism, iron homeostasis is achieved by integrated sp...

15 صفحه اولHuman Iron−Sulfur Cluster Assembly, Cellular Iron Homeostasis, and Disease†
Iron-sulfur (Fe-S) proteins contain prosthetic groups consisting of two or more iron atoms bridged by sulfur ligands, which facilitate multiple functions, including redox activity, enzymatic function, and maintenance of structural integrity. More than 20 proteins are involved in the biosynthesis of iron-sulfur clusters in eukaryotes. Defective Fe-S cluster synthesis not only affects activities ...
