MetabolomicsMetabolite control of enzyme activity links stress to biosynthetic regulation

Cells must continuously adjust metabolic output to maintain homeostasis under changing environmental conditions, yet the mechanisms that enable rapid and reversible control of pathway activity remain largely unknown. The methylerythritol phosphate (MEP) pathway, of bacterial origin and conserved ...

MetabolomicsRepurposing the orphan drug nitisinone to control the transmission of African trypanosomiasis
Tsetse transmit African trypanosomiasis, which is a disease fatal to both humans and animals. A vaccine to protect against this disease does not exist so transmission control relies on eliminating tsetse populations. Although neurotoxic insecticides are the gold standard for insect control, they neg...

ProteomicsConsiderations for peptide and protein error rate control in large-scale targeted DIA analyses
Liquid chromatography coupled to tandem mass spectrometry has become the main method for high-throughput identification and quantification of peptides and the inferred proteins. Discovery proteomics commonly employs data-dependent acquisition in combination with spectrum-centric analysis. The accumu...

MetabolomicsUrine metabolomic profiling in two siblings with biallelic pathogenic ATG7 variants with healthy control
Ultra-rare biallelic ATG7 variants were recently reported in five families presenting with neurodevelopmental disorders. Two adult female siblings (P1 and P2) from one family carried compound heterozygous loss-of-function variants (c.1975C>T [p.Arg659]; c.2080-2A>G, 39,40NM_006395.2), resulting in u...

MetabolomicsIdentification of pre-diagnostic lipid sets associated with liver cancer risk using untargeted lipidomics and chemical set analysis – a nested case-control study within the ATBC cohort

In pre-disposed individuals, a reprogramming of the hepatic lipid metabolism may support liver cancer initiation. We conducted a high-resolution mass spectrometry based untargeted lipidomics analysis of pre-diagnostic serum samples from a nested case-control study (219 liver cancer cases and 219 ...
