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...

MetabolomicsOxygen-induced pathological angiogenesis promotes intense lipid synthesis and remodeling in the retina

The retina is a notable tissue with high metabolic needs which relies on specialized vascular networks to protect the neural retina while maintaining constant supplies of oxygen, nutrients and dietary essential fatty acids. Here we analyzed the lipidome of the mouse retina under healthy and patho...

MetabolomicsComputational mass spectrometry accelerates C=C position-resolved untargeted lipidomics using oxygen attachment dissociation
Mass spectrometry-based untargeted lipidomics has revealed the lipidome atlas of living organisms at the molecular species level. Despite the double bond (C=C) position being a crucial factor for enzyme preference, cellular membrane milieu, and biological activity, the C=C defined structures have no...

MetabolomicsLimited oxygen availability in standard cell culture alters metabolism and function in terminally differentiated cells

Cell culture is generally considered to be hyperoxic. However, the importance of cellular oxygen consumption is often underappreciated, with rates of oxygen consumption often sufficient to cause hypoxia at cell monolayers. We initially focused on cultured adipocytes as a terminally differentiated...

MetabolomicsSMN deficiency perturbs monoamine neurotransmitter metabolism in spinal muscular atrophy

Beyond motor neuron degeneration, homozygous mutations in the survival motor neuron 1 (SMN1) gene cause multiorgan and metabolic defects in patients with spinal muscular atrophy (SMA). However, the precise biochemical features of these alterations and the age of onset in the brain and peripheral ...

ProteomicsOxygen Toxicity Causes Cyclic Damage by Destabilizing Specific Fe-S Cluster-Containing Protein Complexes
Oxygen is toxic across all three domains of life. Yet, the underlying molecular mechanisms remain largely unknown. Here, we systematically investigate the major cellular pathways affected by excess molecular oxygen. We find that hyperoxia destabilizes a specific subset of Fe-S cluster (ISC)-containi...

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...

TranscriptomicsHigh oxygen prevents fetal lethality due to lack of catecholamines
The catecholamine norepinephrine is required for fetal survival, but its essential function is unknown. When catecholamine-deficient [tyrosine hydroxylase (Th) null] mouse fetuses die at E13.5-E14.5, they resemble wild type fetuses exposed to hypoxia. They exhibit bradycardia (28% reduction in hear...

TranscriptomicsOxygen-dependent changes in gene expression in Campylobacter jejuni NCTC 11168
Oxygen transition experiement. Chemostat initially at steady state under oxygen replete conditions (7.5% oxygen input) was perturbed by a reduction in oxygen input (to 1.88% oxygen input). Samples were taken at the 7.5% oxygen and new 1.88% oxygen steady-states and at various points during the trans...

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...
