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...

MetabolomicsIntracellular iron overload rewires HSC metabolism by impairing mitochondrial fitness
Iron is an essential element for several cellular processes and recent evidence highlighted its role in regulating the function of hematopoietic stem cells (HSCs). When in excess it reduces quiescence and self-renewal, however, whether and how iron influences HSC metabolism is still unknown. Here, w...

MetabolomicsMultiomic profiling of iron-deficient infant monkeys reveals alterations in neurologically important biochemicals in serum and cerebrospinal fluid before the onset of anemia

The effects of iron deficiency (ID) during infancy extend beyond the hematologic compartment and include short- and long-term adverse effects on many tissues including the brain. However, sensitive biomarkers of iron-dependent brain health are lacking in humans. To determine whether serum and cer...

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...

MetabolomicsSystem Xc- exacerbates metabolic stress under glucose depletion in oral squamous cell carcinoma

OBJECTIVE: Emerging evidence suggests that glucose depletion (GD)-induced cell death depends on system Xc-, a glutamate/cystine antiporter extensively studied in ferroptosis. However, the underlying mechanism remains debated. Our study confirmed the correlation between system Xc...

MetabolomicsBMAL1-depletion remodels ceramide metabolism to regulate ferroptosis and sorafenib chemosensitivity in acute myeloid leukemia
Acute myeloid leukemia (AML) is a hematologic malignancy with a poor prognosis. We discovered that BMAL1 is a ferroptosis suppressor. Furthermore, it was also found to be overexpressed in AML patients, affecting the cell cycle and promoting tumor cell growth and progression. In this study, we furthe...

TranscriptomicsTranscription profiling of human CaCo-2 cells following various iron treatments
We investigated transcriptional response of CaCo-2 cells to iron treatments, we studied hemin effect by adding hemin to DMEM-FBS medium and iron deficiency effects in using an iron free medium compared to the same supplemented with FAC (ferric ammonium citrate). Experiment Overall Design: Biologica...

TranscriptomicsMR-1 gene expression profiles of iron response
Time-series transcriptional profiles of Shewanella oneidensis type strain MR-1 under iron depletion and repletion conditions. Iron homeostasis of Shewanella oneidensis, a gamma-proteobacterium possessing high iron content, is regulated by a global transcription factor Fur. However, knowledge is inco...

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 ...
