Damped oscillations in the adaptive response of the iron homeostasis network of E. coli

A Amir, S Meshner, T Beatus… - Molecular …, 2010 - Wiley Online Library
Living organisms often have to adapt to sudden environmental changes and reach
homeostasis. To achieve adaptation, cells deploy motifs such as feedback in their genetic …

A heritable iron memory enables decision-making in Escherichia coli

S Bhattacharyya, N Bhattarai… - Proceedings of the …, 2023 - National Acad Sciences
The importance of memory in bacterial decision-making is relatively unexplored. We show
here that a prior experience of swarming is remembered when Escherichia coli encounters a …

Genetic regulation of fluxes: iron homeostasis of Escherichia coli

S Semsey, AMC Andersson, S Krishna… - Nucleic acids …, 2006 - academic.oup.com
Iron is an essential trace-element for most organisms. However, because high concentration
of free intracellular iron is cytotoxic, cells have developed complex regulatory networks that …

[图书][B] Bacterial regulatory networks

A Filloux - 2012 - caister.com
Higher eukaryotic organisms, including humans, use vision, hearing, smell, touch or taste to
promptly analyse the surrounding environment and react appropriately to avoid danger or …

Global iron-dependent gene regulation in Escherichia coli: a new mechanism for iron homeostasis

JP McHugh, F Rodríguez-Quiñones… - Journal of Biological …, 2003 - ASBMB
Organisms generally respond to iron deficiency by increasing their capacity to take up iron
and by consuming intracellular iron stores. Escherichia coli, in which iron metabolism is …

Transcript degradation and noise of small RNA-controlled genes in a switch activated network in Escherichia coli

R Arbel-Goren, A Tal, B Parasar, A Dym… - Nucleic acids …, 2016 - academic.oup.com
Post-transcriptional regulatory processes may change transcript levels and affect cell-to-cell
variability or noise. We study small-RNA downregulation to elucidate its effects on noise in …

Ironing out the problem: new mechanisms of iron homeostasis

E Massé, M Arguin - Trends in biochemical sciences, 2005 - cell.com
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 …

Signal transduction and transcriptional and posttranscriptional control of iron-regulated genes in bacteria

JH Crosa - Microbiology and Molecular Biology Reviews, 1997 - Am Soc Microbiol
Iron is an essential element for nearly all living cells. Thus, the ability of bacteria to utilize
iron is a crucial survival mechanism independent of the ecological niche in which the …

Iron Transport Systems and Iron Homeostasis in Pseudomonas

P Cornelis - Iron Uptake in Bacteria with Emphasis on E. coli and …, 2013 - Springer
During the last few years the knowledge about iron uptake and homeostasis in
Pseudomonas has increased enormously. These very versatile bacteria can adapt to widely …

Switching between apparently redundant iron-uptake mechanisms benefits bacteria in changeable environments

Z Dumas, A Ross-Gillespie… - Proceedings of the …, 2013 - royalsocietypublishing.org
Bacteria often possess multiple siderophore-based iron uptake systems for scavenging this
vital resource from their environment. However, some siderophores seem redundant …
