MetabolomicsTrapped ion mobilty improves annotation accuracy in LC-HRMS screening applications for exposomics

The widespread use of a large number of chemicals results in a significant exposure of humans and the environment, posing potential risks to human health and ecosystems. To assess the exposure to chemical mixtures, screening applications covering a large number of analytes based on liquid chromat...

ProteomicsEvaluation of Protein Ion Relative Ratio Quantification in Top-down Electrospray Ionization–Mass Spectrometry Using Site-Specific Acetylated Recombinant Histone H3 Proteoforms
Electrospray ionization (ESI)-mass spectrometry (MS) provides a crucial platform for analyzing post-translationally modified proteins. With continuous advances in MS instruments and data analysis approaches, analyzing intact proteoforms using a “top-down” approach has become highly feasible. To quan...

MetabolomicsHigh-resolution extracted ion chromatography, a new tool for metabolomics and lipidomics using a second-generation orbitrap mass spectrometer
Most analytical methods in metabolomics are based on one of two strategies. The first strategy is aimed at specifically analysing a limited number of known metabolites or compound classes. Alternatively, an unbiased approach can be used for profiling as many features as possible in a given metabolom...

MetabolomicsWT 2.0: Unveiling the “dark matter” in the metabolome using all-ion stepwise fragmentation acquisition mode (ASFAM) and deep learning-based feature extraction

Current metabolomics methods often miss low-abundance compounds and yield incomplete or ambiguous MS2 spectra, resulting in the presence of “dark matter” within the metabolome. Here, we introduce WT 2.0, which employs an all-ion stepwise fragmentation acquisition mode (ASFAM) to acquire comprehe...

MetabolomicsFatty acid transport protein 4 is required for incorporation of saturated ultralong-chain fatty acids into epidermal ceramides and monoacylglycerols
Fatty acid transport protein 4 (FATP4) is an acyl-CoA synthetase that is required for normal permeability barrier in mammalian skin. FATP4 (SLC27A4) mutations cause ichthyosis prematurity syndrome, a nonlethal disorder. In contrast, Fatp4-/- mice die neonatally from a defective barrier. H...

ProteomicsA Triple Knockout (TKO) Proteomics Standard for Diagnosing Ion Interference in Isobaric Labeling Experiments
Isobaric labeling is a powerful strategy for quantitative mass spectrometry-based proteomic investigations. A complication of such analyses has been the co-isolation of multiple analytes of similar mass-to-charge resulting in the distortion of relative protein abundance measurements across samples. ...

MetabolomicsProtein lactylation of citrate synthase promotes the AKI–CKD transition by activating the NLRP3 inflammasome.

Interstitial renal inflammation contributes to the transition from acute kidney injury (AKI) to chronic kidney disease (CKD). Recently, protein lactylation modification has emerged as a novel mechanism for mediating chronic organ damage. We investigated lactylated protein profiles and the role of...

MetabolomicsWalnut protein hydrolysate alleviates neuroinflammation and memory impairment in naturally aged mice via a gut microbiota-metabolite-neuroinflammation axis
This study investigated age-associated alterations in the serum metabolome and the metabolic effects of walnut protein hydrolysate (WPH) supplementation in naturally aged mice. Male C57BL/6J mice at different ages (2-month, 10-month and 18-month) were used to characterize metabolic changes associate...

ProteomicsRatio accuracy evaluation and correction using tandem mass tags
The multiplexing capabilities of isobaric mass tag based protein quantification, such as Tandem Mass Tags (TMT) or Isobaric Tag for Relative and Absolute Quantitation (iTRAQ) have dramatically increased the scope of Mass Spectrometry (MS) based proteomics studies. Not only does the technology allow ...

MetabolomicsIdentification of BolA protein reveals a novel virulence factor in Klebsiella pneumoniae that contributes to liver abscess in mice

BolA has been characterized as an important transcriptional regulator, which is induced in the stationary phase of growth and is often associated with bacterial virulence. This study was initiated to elucidate the role of the BolA in the virulence of K. pneumoniae. Using a mous...
