MetabolomicsHierarchical Carbon Metabolism in Iron-Deficient Bacteria Favors Iron-Scavenging Strategy

High-affinity iron (Fe) scavenging compounds, or siderophores, are widely employed by soil bacteria to survive scarcity in bioavailable Fe. Siderophore biosynthesis relies on cellular carbon metabolism, despite reported decrease in both carbon uptake and Fe-containing metabolic proteins in Fe-def...

MetabolomicsToxoplasma gondii metabolic flexibility in response to iron deprivation

Iron is an essential nutrient for many critical cellular processes. As a consequence of diverse and dynamic host environments, the obligate intracellular parasite Toxoplasma gondii must adapt to iron limited conditions. To investigate the adaptations critical to parasite survival under these cond...

MetabolomicsClostridium bolteae suppresses Enterobacteriaceae expansion and restores gut microbiome homeostasis via disrupting siderophore-mediated iron acquisition

Intestinal inflammation and the related gut microbiome dysbiosis are becoming prevalent worldwide. Overgrowth of Enterobacteriaceae exacerbates intestinal inflammation and gut microbiome dysbiosis. Enterobacteriaceae secrets siderophore to acquire iron and survive in the iron-limited gut. Therefo...

TranscriptomicsIron uptake experiments in yeast
The budding yeast S. cerevisiae responds to depletion of iron in the environment by activating Aft1p, the major iron-dependent transcription factor, and by transcribing systems involved in the uptake of iron. Here we have studied the transcriptional response to iron deprivation, and have identified ...

MetabolomicsCitrate serves as a signal molecule to modulate carbon metabolism and iron homeostasis in Staphylococcus aureus

Pathogenic bacteria's metabolic adaptation for survival and proliferation within hosts is a crucial aspect of bacterial pathogenesis. Here, we demonstrate that citrate, the first intermediate of the tricarboxylic acid (TCA) cycle, plays a key role as a regulator of gene expression in Staphylococc...

TranscriptomicsExpression data from Arabidopsis roots and shoots grown with or without iron
Iron-deficiency repsonses in Arabidopsis are controlled by several bHLH transcription factors. FIT, for example has been shown to direct iron-uptake responses. However, the role of shoot and root expressed genes bHLH100 and bHLH101 has not be clarified. We used microarray to study what genes migh...

TranscriptomicsMpeR regulation in Neisseria gonorrhoeae (F19) through an iron-responsive mechanism
Previous studies have shown that the MpeR transcriptional regulator produced by Neisseria gonorrhoeae represses expression of mtrF, which encodes a putative inner membrane protein that works with the MtrC-MtrD-MtrE efflux pump to allow gonococci to resist high levels of multiple hydrophobic antimicr...

TranscriptomicsTranscription profiling of rat duodenal samples at different developmental stages and the effects of iron-deficiency
The effect of iron-deficiency on duodenal gene expression was investigated in rats at different developmental stages.

TranscriptomicsTranscription profiling of Mycobacterium tuberculosis wild type, ideR mutant and ideR complemented mutants strains grown in iron-sufficient or iron-deficient media
The mycobacterial IdeR protein is a metal-dependent regulator of the DtxR (diphtheria toxin repressor) family. In the presence of iron, it binds to a specific DNA sequence in the promoter regions of the genes that it regulates, thus controlling their transcription. In this study, we provide evidence...
