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...

Toxoplasma uses metal nutrients like iron and copper for vital functions in their energy metabolism. Here, we have used stable isotope labelling to track the incorporation of glucose and glutamine into metabolic pathways, primarily focusing on central carbon metabolism, when these metals are disr...

Human retinal vascular endothelial cells (HRECs) were transfected with lentivirus encoding either KIF11-targeting shRNA or a non-targeting control. KIF11-depleted and control cells were then subjected to lipid extraction followed by LC–MS/MS–based targeted analysis of ferroptosis-associated phosp...

Effects of iron starvation on the transcriptional profile of Bacillus anthracis
ORGANISM(S): Bacillus anthracis 
Bordetella bronchiseptica RB50 was shifted from iron replete to either iron depleted or iron replete media, and samples were taken post shift for transcriptional profiling
ORGANISM(S): Bordetella bronchiseptica 
DC3000 cultures were grown under highly controlled conditions and after the addition of iron citrate or sodium citrate to the media. In the cultures supplemented with iron, we found that cell-associated iron increased rapidly while culture densities were not significantly different over 4 hours when...
ORGANISM(S): Pseudomonas syringae pv. tomato str. DC3000 
B. pertussis Tohama I was grown in iron-depleted or iron-replete media and sampled at several time points to assess global gene expression
ORGANISM(S): Bordetella pertussis 
The paralogous transcription factors Aft1p and Aft2p activate the expression of genes involved in iron metabolism under iron depleted conditions. Both are able to bind to the same DNA consensus sequence in vitro. We used DNA microarrays and loss of function mutant strains to better understand the re...
ORGANISM(S): Saccharomyces cerevisiae 
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...
ORGANISM(S): Mycobacterium tuberculosis 
Data from ProteomeXchange, PXD ID: PXD001280. File: 120313_O4_YL__Bp_Fe_1.mzml. Published as part of Proteomics. 2015 Mar 9 . From the Abstract: {{i}} One of the mechanisms involved in host immunity is the limitation of iron accessibility to pathogens, which in turn provokes the corresponding physi...
