Transcriptomicsdelta-arcS versus wild-type
The availability of oxygen is a major environmental factor for many microbes, in particular for bacteria, such as Shewanella species, which thrive in redox-stratified environments. One of the best studied systems involved in mediating the response to changes in environmental oxygen levels is the Arc...

TranscriptomicsOxygen-dependent transcriptome profiling in R.sphaeroides 2.4.1 in the dark
Wild type (2.4.1) strain, dark conditions, controlled oxtgen concentration in the growth medium (achieved by constant sparging with a gas mixture containing 1% CO2, variable - indicated for every sample - concentration O2 and balance N2). Keywords: dose response Cells were harvested at OD 0.16-0.18...

TranscriptomicsMetabolic responses of the model archaeon Halobacterium sp. NRC-1 to oxygen limitation
As part of a comprehensive post-genomic investigation of the model archaeon Halobacterium sp. NRC-1, we used whole genome DNA microarrays to compare transcriptional profiles of cells grown anaerobically via arginine fermentation versus cells either respiring aerobically in the presence of oxygen or ...

TranscriptomicsMicroarray data from pre-germinated seeds and hypoxia-treated seedlings of Arabidopsis prt6-1 and ate1 ate2 mutants of the N-end rule pathway of targeted proteolysis pathway
This study analyzes transcriptome profiles in pre-germinated seeds and hypoxia-treated seedlings of Arabidopsis thaliana wild type (Col-0) and homozygous mutants (prt6-1 and ate1 ate2). This dataset includes CEL files, RMA signal values and MAS5 P/M/A calls. For pre-germinated seeds, seeds imbibed f...

TranscriptomicsExpression profile of mouse carotid body and adrenal medulla [RNA-Seq]
The carotid body is a chemoreceptor that senses decreases in blood oxygen to increase breathing in hypoxia. To look for candidate oxygen sensors in the carotid body, we compared the gene expression of the carotid body to the adrenal medulla, a similar tissue that does not have oxygen sensitivity in ...

TranscriptomicsThe unique roles of DosT and DosS in DosR regulon induction and Mycobacterium tuberculosis dormancy
In Mycobacterium tuberculosis, the sensor kinases DosT and DosS activate the transcriptional regulator DosR, resulting in the induction of the DosR regulon, important for anaerobic survival and perhaps latent infection. The individual and collective roles of these sensors has been postulated biochem...

TranscriptomicsExpression data from Arabidopsis seedlings expressing a synthetic oxygen sensor device
Gene expression was compared between 7-day old seedlings expressing two effector modules of an oxygen sensor device,consisting of the Saccharomyces cerevisiae Gal4 activation domain (AD) fused to the human HIF-CODD and the Gal4 DNA binding domain (BD) fused to the human pVHL, and seedlings expressin...

ProteomicsThe Vibrio vulnificus stressosome: an oxygen-sensor involved in regulating iron metabolism
Stressosomes are stress-sensing protein complexes widely conserved among bacteria. Although a role in the regulation of the general stress response is well documented in Gram-positive bacteria, the activating signals are still unclear, and little is known about the physiological function of stressos...
