MetabolomicsCharacterizing ex vivo models for studying lipid metabolism in triple negative breast cancer

Lipid metabolism drives cancer progression but is difficult to model using conventional methods. In vivo models provide circulating lipids, but are costly and low throughput, while in vitro models lack sufficient lipid availability in culture media. Here, we evaluate the chick chorioallantoic mem...

MetabolomicsEx-Vivo Equine Cartilage Explant Osteoarthritis Model - A Metabolomics and Proteomics Study
Osteoarthritis (OA) is an age-related degenerative musculoskeletal disease characterised by loss of articular cartilage, synovitis, abnormal bone proliferation and subchondral bone sclerosis. Underlying OA pathogenesis is yet to be fully elucidated with no OA specific biomarkers in clinical use. Ex-...

MetabolomicsInterorganelle lipid flux revealed by enzymatic mass tagging in vivo
The distinct activities of cellular organelles are dependent on the proper function of their membranes. Coordinated membrane biogenesis of the different organelles necessitates interorganelle transport of lipids from their site of synthesis to their destination membranes. Several proteins and traffi...

MetabolomicsIn Vitro and In Vivo Metabolomic Profiling after Infection with Virulent Newcastle Disease Virus
Newcastle disease (ND) is an acute, febrile, and highly contagious disease caused by the virulent Newcastle disease virus (vNDV) worldwide. The disease causes serious economic losses to the poultry industry. However, the metabolic changes caused by vNDV infection remain unclear. The objective of thi...

MetabolomicsMetabolic response to point mutations reveals principles of modulation of in vivo enzyme activity and phenotype
The relationship between sequence variation and phenotype is poorly understood. Here, we use metabolomic analysis to elucidate the molecular mechanism underlying the filamentous phenotype of E. coli strains that carry destabilizing mutations in dihydrofolate reductase (DHFR). We find that partial lo...

MetabolomicsNovel Minor Groove Binders cure animal African trypanosomiasis in an in vivo mouse model
Animal African trypanosomiasis (AAT) is a significant socioeconomic burden for sub-Saharan Africa because of its huge impact on livestock health. Existing therapies including those based on minor groove binders (MGBs), such as the diamidines, which have been used for decades, have now lost efficacy ...

MetabolomicsEffects of a Compound from the Group of Substituted Thiadiazines with Hypothermia Inducing Properties on Brain Metabolism in Rats, a Study In Vivo and In Vitro
The aim of the present study was to examine how administration of a compound of 1,3,4-thiadiazine class 2-morpholino-5-phenyl-6H-1,3,4-thiadiazine hydrobromide (L-17) with hypothermia inducing properties affects the brain metabolism. The mechanism by which L-17 induces hypothermia is unknown; it may...

MetabolomicsGlobal 13C tracing and metabolic flux analysis of intact human liver tissue ex vivo
Liver metabolism is central to human physiology and influences the pathogenesis of common metabolic diseases. Yet, our understanding of human liver metabolism remains incomplete, with much of current knowledge based on animal or cell culture models that do not fully recapitulate human physiology. He...

MetabolomicsHuman gut bacteria increase PFNA excretion in vivo

Per- and polyfluoroalkyl Substances (PFAS) – the so-called ‘forever chemicals’ – are a major cause of environmental and health concern due to their toxicity and long-term persistence. Yet, no efficient mechanisms for their removal have been identified. Here we report the potential of human gut ba...

Metabolomics13C glucose labelling studies using 2D NMR is a useful tool for determining ex vivo whole organ metabolism during hypothermic machine perfusion of kidneys
Background: The aim of this study is to determine the feasibility of using Nuclear Magnetic Resonance (NMR) tracer studies (13C-enriched glucose) to detect ex vivo de novo metabolism in the perfusion fluid and cortical tissue of porcine kidneys during hypothermic machine perfusion (HMP). Methods: Po...
