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...

MetabolomicsChronic sleep loss sensitizes Drosophila melanogaster to nitrogen stress

Chronic sleep loss profoundly impacts metabolic health and shortens lifespan, but studies of the mechanisms involved have focused largely on acute sleep deprivation. To identify metabolic consequences of chronically reduced sleep, we conducted unbiased metabolomics on heads of three adult Drosoph...

MetabolomicsCardiac disruption of SDHAF4-mediated mitochondrial complex II assembly promotes dilated cardiomyopathy
Succinate dehydrogenase, which is known as mitochondrial complex II, has proven to be a fascinating machinery, attracting renewed and increased interest in its involvement in human diseases. Herein, we find that succinate dehydrogenase assembly factor 4 (SDHAF4) is downregulated in cardiac muscle in...

MetabolomicsTFAM loss induces nuclear actin assembly upon mDia2 malonylation to promote liver cancer metastasis
The mechanisms underlying cancer metastasis remain poorly understood. Here, we report that TFAM deficiency rapidly and stably induced spontaneous lung metastasis in mice with liver cancer. Interestingly, unexpected polymerization of nuclear actin was observed in TFAM-knockdown HCC cells when cytoske...

MetabolomicsACOD1 deficiency promotes dermal papilla cell senescence via mitochondrial dysfunction in androgenetic alopecia

Background Androgenetic alopecia (AGA), the most prevalent form of hair loss, is driven by the dysfunction of dermal papilla cells (DPCs). Emerging evidence implicates DPC senescence in the pathogenesis of AGA; however, the underlying molecular mechanisms remain incompletely elucidated.

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 ...

MetabolomicsPhospholipid acyl chain diversity controls the tissue-specific assembly of mitochondrial cardiolipins

Cardiolipin (CL) is a phospholipid specific for mitochondrial membranes and crucial for many core tasks of this organelle. Its side chain configurations are tissue-specific, functionally important and generated via post-biosynthetic remodeling. However, this process lacks the necessary specificit...

MetabolomicsIAPP toxicity activates HIF1α/PFKFB3 signaling delaying β-cell loss at the expense of β-cell function
The islet in type 2 diabetes (T2D) is characterized by amyloid deposits derived from islet amyloid polypeptide (IAPP), a protein co-expressed with insulin by β-cells. In common with amyloidogenic proteins implicated in neurodegeneration, human IAPP (hIAPP) forms membrane permeant toxic oligomers imp...

MetabolomicsRibosomal mistranslation leads to silencing of the unfolded protein response and increased mitochondrial biogenesis

Translation fidelity is the limiting factor in the accuracy of gene expression. With an estimated frequency of 10-4, errors in mRNA decoding occur in a mostly stochastic manner. Little is known about the response of higher eukaryotes to chronic loss of ribosomal accuracy as per an increase in the...
