Inflaming the brain with iron
(MDPI, 2021)
Iron accumulation and neuroinflammation are pathological conditions found in several neurodegenerative diseases, including Alzheimer's disease (AD) and Parkinson's disease (PD). Iron and inflammation are intertwined in a ...
The role of fur in the transcriptional and Iron homeostatic response of Enterococcus faecalis
(Frontiers Media, 2018)
The ferric uptake regulator (Fur) plays a major role in controlling the expression of iron homeostasis genes in bacterial organisms. In this work, we fully characterized the capacity of Fur to reconfigure the global ...
Iron homeostasis in neuronal cells: A role for IREG1
(2005)
Background: Iron is necessary for neuronal function but in excess generates neurodegeneration. Although most of the components of the iron homeostasis machinery have been described in neurons, little is known about the ...
Iron toxicity in neurodegeneration
(2012)
Iron is an essential element for life on earth, participating in a plethora of cellular processes where one-electron transfer reactions are required. Its essentiality, coupled to its scarcity in aqueous oxidative environments, ...
Effect of malnutrition on iron homeostasis in black-necked swans (Cygnus melanocoryphus).
(2009)
The Cayumapu River black-necked swan (Cygnus melanocoryphus) population in southern Chile suffered a syndrome of malnutrition and hyperferremia in 2005. The iron metabolic imbalance could not be explained on the basis of ...
Effects of acute creatine supplementation on iron homeostasis and uric acid-based antioxidant capacity of plasma after wingate test
(BIOMED CENTRAL LTD, 2012)
Background: Dietary creatine has been largely used as an ergogenic aid to improve strength and athletic performance, especially in short-term and high energy-demanding anaerobic exercise. Recent findings have also suggested ...
Regulation of Fe absorption by cultured intestinal epithelia (Caco-2) cell monolayers with varied Fe status
(1996)
Body Fe homeostasis is maintained through the regulation of Fe absorption by the intestinal epithelia. Working under the hypothesis that the intracellular concentration of Fe is instrumental in the control of its transepithelial ...
Iron at the center of ferritin, metal/oxygen homeostasis and novel dietary strategies
(Sociedad de Biología de Chile, 2006)
The interplay between iron accumulation, mitochondrial dysfunction and inflammation during the execution step of neurodegenerative disorders
(Frontiers Research Foundation, 2014)
A growing set of observations points to mitochondrial dysfunction, iron accumulation, oxidative damage and chronic inflammation as common pathognomonic signs of a number of neurodegenerative diseases that includes Alzheimer's ...
Iron homeostasis strategies in acidophilic iron oxidizers: Studies in Acidithiobacillus and Leptospirillum
(Elsevier B.V., 2008-11)
An understanding of the physiology and metabolic complexity of microbial consortia involved in metal
solubilization is a prerequisite for the rational improvement of bioleaching technologies. Among the most
challenging ...
