MetabolomicsFate and PPARγ and STATs-driven effects of the mitochondrial complex I inhibitor tebufenpyrad in liver cells revealed with multi-omics.
The biological effects of the pesticide and mitochondrial complex I inhibitor tebufenpyrad (TEBU) on liver cells were investigated by combining proteomics and metabolomics. Both cell culture media and cellular lysates were analyzed in dose-response and kinetic experiments on the HepaRG cell line. Re...

MetabolomicsSARS-CoV-2 ORF7a Drives Mitochondrial Dysfunction via PDK4 Activation and Complex I Inhibition

SARS-CoV-2 reprograms host metabolism to promote viral replication and evade immune responses. While infection is known to impair mitochondrial function and enhance glycolysis, the role of viral accessory proteins in these alterations remains unclear. Here, we investigate the metabolic impact of ...

TranscriptomicsTranscription profiling of yeast rho0 cells (complete deletion of the mitochondrial genome), in cells with either a single defective enzyme or several, vs cells after prolonged treatment with the bc1 inhibitors myxothiazol or antimycin to analyse respiratory defects
The mitochondrial respiratory chain is composed of lipoprotein complexes imbedded in the inner mitochondrial membrane. This chain of enzymes transfers electrons from NADH and FADH2, provided from divers metabolic pathways, to oxygen. It couples the transfer of electrons to the translocation of proto...

ProteomicsSubcellular proteomics combined with bioenergetic phenotyping reveals protein biomarkers of respiratory insufficiency in the setting of compromised mitochondrial DNA repair.
The mitochondrial mutator mouse is a well-established model of premature aging in which a progeroid phenotype is driven by the accumulation of somatic mtDNA mutations. Despite evidence of bioenergetic disruption within the cardiac mitochondria, there is little information about the underlying change...

TranscriptomicsTranscription profiling of mouse age-related hearing loss cochlea in DBA/2J
Age-related hearing loss (AHL) is the progressive loss of auditory function with aging. The DBA/2J (DBA) mice have been used as a model of AHL and undergoes progressive, age-related hearing loss by 12 weeks of age. Here we analyzed cochlear gene expression of 7-week-old and 36-week-old DBA mice usin...

MetabolomicsComprehensive Metabolic Profiling of Age-Related Mitochondrial Dysfunction in the High-Fat-Fed ob/ob Mouse Heart
The ectopic deposition of fat is thought to lead to lipotoxicity and has been associated with mitochondrial dysfunction and diabetic cardiomyopathy. We have measured mitochondrial respiratory capacities in the hearts of ob/ob and wild-type mice on either a regular chow (RCD) or high-fat (HFD) diet a...

MetabolomicsMitochondrial metabolism sustains DNMT3A-R882-mutant clonal haematopoiesis
Somatic DNMT3A R882 codon mutations drive the most common form of clonal haematopoiesis (CH) and are associated with increased acute myeloid leukaemia (AML) risk1,2. Preventing expansion of DNMT3A-R882-mutant haematopoietic stem/progenitor cells (HSPCs) may therefore avert progression to AML. To ide...

MetabolomicsMitochondrial respiration controls neoangiogenesis during wound healing and tumour growth

The vasculature represents a highly plastic compartment, capable of switching from a quiescent to an active proliferative state during angiogenesis. Metabolic reprogramming in endothelial cells (ECs) thereby is crucial to cover the increasing cellular energy demand under growth conditions. Here w...

MetabolomicsSelective galactose culture condition reveals distinct metabolic signatures in pyruvate dehydrogenase and complex I deficient human skin fibroblasts

INTRODUCTION: A decline in mitochondrial function represents a key factor of a large number of inborn errors of metabolism, which lead to an extremely heterogeneous group of disorders.

OBJECTIVES: To gain insight into the biochemical consequences of mitocho...

MetabolomicsMolecular structural diversity of mitochondrial cardiolipins
Current strategies used to quantitatively describe the biological diversity of lipids by mass spectrometry are often limited in assessing the exact structural variability of individual molecular species in detail. A major challenge is represented by the extensive isobaric overlap present among lipid...
