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...

MetabolomicsSIN-3 transcriptional coregulator maintains mitochondrial homeostasis and polyamine flux
Mitochondrial function relies on the coordinated transcription of mitochondrial and nuclear genomes to assemble respiratory chain complexes. Across species, the SIN3 coregulator influences mitochondrial functions, but how its loss impacts mitochondrial homeostasis and metabolism in the context of a ...

MetabolomicsMitochondrial respiration in B lymphocytes is essential for humoral immunity by controlling flux of the TCA cycle

To elucidate the function of oxidative phosphorylation (OxPhos) during B-cell differentiation we employ CD23Cre-driven expression of the dominant-negative K320E mutant of the mitochondrial helicase Twinkle (DNT). DNT-expression depletes mitochondrial DNA during B cell maturation, reduces the abun...

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...

TranscriptomicsGene expression analysis in 13 patients with mitochondrial ATP synthase deficiency (Agilent)
Defects of mitochondrial functions lead in humans to vast array of usually multisystemic pathologies and several hundreds of diseases resulting from various defects of mitochondria biogenesis and maintenance, defects of respiratory chain complexes (OXPHOS) or defects of individual mitochondrial prot...

TranscriptomicsLooking for mitochondrial associated RNA
We investigated the peripheral mitochondrial localization of nuclear-encoded mRNAs (MLR) in various conditions in which translation was inhibited or the mRNA binding protein context altered (Delta puf3). We used cell fractionation protocols together with microarray to assess the distribution of mRNA...

MetabolomicsDefective mitochondrial COX1 translation due to loss of COX14 function triggers ROS-induced inflammation in liver
Mitochondrial oxidative phosphorylation (OXPHOS) fuels cellular ATP demands. OXPHOS defects lead to severe human disorders with unexplained tissue specific pathologies. Mitochondrial gene expression is essential for OXPHOS biogenesis since core subunits of the complexes are mitochondrial-encoded. CO...

ProteomicsComplexome profiling of mitochondrial protein complexes from pig heart to study the molecular consequences of hyperbaric oxygen treatment
The overall goal of the project was to confirm the presence of different energetic states of mitochondrial subpopulations depending on their subcellular localization within cardiomyocytes, i.e., subsarcolemmal (SSM) and interfibrillar mitochondria (IFM). At the same time, we aimed to elucidate possi...
