TranscriptomicsTranscription profiling of Arabidopsis adaptive response to decreases in oxygen concentration in root
- Background and Aims: Oxygen can fall to low concentrations within plant tissues, either because of environmental factors that decrease the external oxygen concentration or because the movement of oxygen through the plant tissues cannot keep pace with the rate of oxygen consumption. Recent studies ...

ProteomicsIn Vivo Protein Turnover Rates in Varying Oxygen Tensions Nominate MYBBP1A as a Novel Mediator of the Hyperoxia Response
Oxygen deprivation and excess are both toxic to mammals. Thus, the ability to adapt to varying oxygen tensions is critical for survival. While the transcriptional response to acute hypoxia has been well-studied, the post-translational effects of hypoxia and hyperoxia have been underexplored. In this...

TranscriptomicsMetabolic regulation of ‘Ca. Methylacidiphilum fumariolicum’ SolV cells grown under different nitrogen and oxygen limitations
Aerobic methanotrophic bacteria can use methane as their sole energy source. The discovery of ‘Ca. Methylacidiphilum fumariolicum’ strain SolV and other verrucomicrobial methanotrophs has revealed that the ability of bacteria to oxidize CH4 is much more diverse than has previously been assumed in te...

TranscriptomicsMultiple oxygen tension environments reveal diverse patterns of transcriptional regulation in primary astrocytes
The central nervous system normally functions at O2 levels which would be regarded as hypoxic by most other tissues. However, most in vitro studies of neurons and astrocytes are conducted under hyperoxic conditions without consideration of O2-dependent cellular adaptation. We analyzed the reactivi...

MetabolomicsReactive Oxygen Species Deficiency Due to Ncf1-Mutation Leads to Development of Adenocarcinoma and Metabolomic and Lipidomic Remodeling in a New Mouse Model of Dextran Sulfate Sodium-Induced Colitis
Inflammatory bowel disease is characterized by chronic relapsing idiopathic inflammation of the gastrointestinal tract and persistent inflammation. Studies focusing on the immune-regulatory function of reactive oxygen species (ROS) are still largely missing. In this study, we analyzed an ROS-deficie...

TranscriptomicsRNA-Seq transcriptional analysis of Herbaspirillum seropedicae fnr1 and fnr3 deletion mutants in comparison with the wild type under two different oxygen regimes
To systematically address the role of different Fnr proteins in the transcription regulation in response to varying oxygen levels, we have established an oxygen switch protocol to study the transcriptional changes directly or indirectly associated with these oxygen-sensitive regulatory proteins. To ...

TranscriptomicsLow oxygen responsive small RNAs in Arabidopsis
Low-oxygen stress associated with natural phenomena such as waterlogging, results in widespread transcriptome changes and a metabolic switch from aerobic respiration to anaerobic fermentation. High-throughput sequencing of small RNA libraries obtained from low-oxygen stressed and control root tissue...

TranscriptomicsTranscription profiling by array of Burkholderia cenocepacia J2315 grown under low or atmospheric oxygen concentration conditions
B. cenocepacia J2315 was grown on LB medium to mid-stationary phase at OD 0.3 under full aeration and then transferred into a 50 ml centrifuge tube and placed upright into a CampyGen Compact (Oxoid, Basingstoke, UK) plastic pouch containing the gas generating paper sachet. The pouch was sealed immed...

TranscriptomicsTranscription profiling by array of Burkholderia cenocepacia J2315 was exposed to heat stress and to stress form reactive oxygen species
B. cenocepacia J2315 was exposed to heat stress and to stress form reactive oxygen species.
To expose the cultures to heat stress, cells were grown at 37ºC to an O.D. of 0.4 to 0.45 and then transferred into a different shaking incubator at 42.5ºC, incubated for 1 hour at 150 rpm and harvested.<...

MetabolomicsPhotosynthetic Carbon Partitioning and Metabolic Regulation in Response to Very-Low and High CO2 in Microchloropsis gaditana NIES 2587
Photosynthetic organisms fix inorganic carbon through carbon capture machinery (CCM) that regulates the assimilation and accumulation of carbon around ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco). However, few constraints that govern the central carbon metabolism are regulated by the ca...
