Altered levels of AtHSCB disrupts iron translocation from roots to shoots
(Springer, 2016-11)
Key message: Plants overexpressing AtHSCB and hscb knockdown mutants showed altered iron homeostasis. The overexpression of AtHSCB led to activation of the iron uptake system and iron accumulation in roots without concomitant ...
Role of redox systems on Fe3+ uptake by transformed human intestinal epithelial (Caco-2) cells
(1994)
Caco-2 cells were used as a model of human intestinal epithelium to investigate the role of redox systems in transepithelial transport of 59Fe3+. The cells reduced Fe3+ present in the apical medium; the reduction was 50% ...
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 ...
IurV, encoded by ORF VCA0231, is involved in the regulation of iron uptake genes in vibrio cholerae
(MDPI, 2020)
The pathogen Vibrio cholerae has multiple iron acquisition systems which allow bacteria to exploit a variety of iron sources across the different environments on which it thrives. The expression of such iron uptake systems ...
DMT1 as a candidate for non-transferrin-bound iron uptake in the peripheral nervous system
(Wiley, 2013-07)
Iron, either in its chelated form or as holotransferrin (hTf), prevents the dedifferentiation of Schwann cells (SC), cells responsible for the myelination of the peripheral nervous system (PNS). This dedifferentiation is ...
Selective response to iron and epo signals of iron cycle proteins in a mouse model
(Fundación Revista Medicina, 2020)
The Erythropoietin (EPO) is associated with iron mobilization.The aim was to analyze the regulatory relationship between iron and EPO studying iron key proteins in several tissues in an animal model of iron overload and ...
Ferric iron uptake genes are differentially expressed in the presence of copper sulfides in Acidithiobacillus ferrooxidans strain LR
(Springer, 2011-03-01)
Acidithiobacillus ferrooxidans is one of the most widely used microorganisms in bioleaching operations to recover copper from low-grade copper sulfide ores. This work aimed to investigate the relative expression of genes ...

Global transcriptional response of Caulobacter crescentus to iron availability
(BioMed CentralLondres, 2013-08)
BACKGROUND:
In the alpha subclass of proteobacteria iron homeostasis is controlled by diverse iron responsive regulators. Caulobacter crescentus, an important freshwater α-proteobacterium, uses the ferric uptake repressor ...
Genomic insights into the iron uptake mechanisms of the biomining microorganism Acidithiobacillus ferrooxidans
(SPRINGER HEIDELBERG, 2005-12)
Commercial bioleaching of copper and the
biooxidation of gold is a cost-effective and environmentally
friendly process for metal recovery. A partial
genome sequence of the acidophilic, bioleaching bacterium
Acidithiobacillus ...
