Models,MultiomicsIron acquisition and oxidative stress response in aspergillus fumigatus.
Aspergillus fumigatus is a ubiquitous airborne fungal pathogen that presents a life-threatening health risk to individuals with weakened immune systems. A. fumigatus pathogenicity depends on its ability to acquire iron from the host and to resist host-generated oxidative stress. Gaining a deeper und...

ProteomicsSurviving oxidative stress under iron starvation: an important lesson eminently learned by Aspergillus fumigatus in the human body
Aspergillus fumigatus has to cope with a combination of several stress types after colonisng the human body, and the interplay between the different stress responses can significantly influence the survival of this human pathogen during the invasion of the host organism. In this study, we examined h...

TranscriptomicsRole of IdeR in Iron-Dependent Gene Expression, Iron Metabolism, and Oxidative Stress Response
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...

TranscriptomicsTranscription profiling of S. cerevisiae (budding yeast) mutants reveals Isc1p plays a key role in hydrogen peroxide resistance and chronological lifespan through modulation of iron levels and programmed cell death
Changes in the transcriptome of Isc1p deficient mutants. The inositolphosphosphingolipid phospholipase C (Isc1p) of Saccharomyces cerevisiae belongs to the family of neutral sphingomyelinases that generates the bioactive sphingolipid ceramide. In this work the role of Isc1p in oxidative stress resis...

ProteomicsResponse of Haloferax volcanii to low-iron stress
We analyzed the response of the haloarchaeal model organism Haloferax volcanii to low iron stress on the proteome level by label-free mass spectrometry. Cells grown in minimal medium with normal iron levels were compared to those grown under low iron conditions. We separated the samples into soluble...

TranscriptomicsThe Arabidopsis copper transport protein COPT2 and the responses under copper and iron deficiency.
Copper and iron are essential micronutrients for most living organisms because they participate as cofactors in biological processes including respiration, photosynthesis and oxidative stress protection. In many eukaryotic organisms, including yeast and mammals, copper and iron homeostases are highl...
