MetabolomicsThe Sphingolipidome of the model organism Caenorhabditis elegans
Sphingolipids are important lipids and integral members of membranes, where they form small microdomains called lipid rafts. These rafts are enriched in cholesterol and sphingolipids, which influences biophysical properties. Interestingly, the membranes of the biomedical model organism Caenorhabditi...

MetabolomicsComparison of lipidome profiles of Caenorhabditis elegans—results from an inter-laboratory ring trial

Introduction

Lipidomic profiling allows 100s if not 1000s of lipids in a sample to be detected and quantified. Modern lipidomics techniques are ultra-sensitive assays that enable the discovery of novel biomarkers in a variety of fields and provide new insight in mechanistic investigations. D...

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 ...

MetabolomicsLipidFrag: Improving reliability of in silico fragmentation of lipids and application to the Caenorhabditis elegans lipidome
Lipid identification is a major bottleneck in high-throughput lipidomics studies. We combined the in silico fragmentation tool MetFrag with LipidMaps lipid-class specific classifiers which calculate probabilities for lipid class assignments. The LipidFrag approach was then applied to MS/MS spectra o...

MetabolomicsPolyketide synthase-derived sphingolipids determine microbiota-mediated protection against pathogens in C. elegans

Protection against pathogens is a major function of the gut microbiota. Although bacterial natural products have emerged as crucial components of host-microbiota interactions, their exact role in microbiota-mediated protection is largely unexplored. We addressed this knowledge gap with the nemato...

MetabolomicsDIAMetAlyzer allows automated false-discovery rate-controlled analysis for data-independent acquisition in metabolomics
The extraction of meaningful biological knowledge from high-throughput mass spectrometry data relies on limiting false discoveries to a manageable amount. For targeted approaches in metabolomics a main challenge is the detection of false positive metabolic features in the low signal-to-noise ranges ...

MetabolomicsUntargeted metabolomics analyses and contaminant chemistry of Dreissenid mussels at the Maumee River Area of Concern in the Great Lakes

Bivalves serve as an ideal ecological indicator; hence, their use by the NOAA Mussel Watch Program to monitor environmental health. This study aimed to expand the baseline knowledge of using metabolic end points in environmental monitoring by investigating the dreissenid mussel metabolome in the ...

ProteomicsEffect of Mavacamten on skeletal muscle fibre proteome in nemaline myopathy
Nemaline myopathy (NM) is a genetic muscle disorder, notably caused by mutations in the NEB gene (NEB-NM). Here we investigated the efficacy of a four-week Mavacamten (myosin ATPase inhibitor) treatment using a NEB-NM mouse model. After the four weeks, soleus muscles were extracted, muscle fibres we...
