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 ...

MetabolomicsDIATAGeR: Triacylglycerol Annotation of Data-Independent Acquisition based Lipidomics

Triacylglycerols (TGs) are the most abundant lipids in the human body and the primary source of energy storage. Altered TGs are implicated in metabolic syndrome and detailed structural information may provide novel insights into diseases pathology. TGs are comprised of three fatty acyls with vari...

MetabolomicsHigh-performance nano-flow liquid chromatography column combined with high- and low-collision energy data-independent acquisition enables targeted and discovery identification of modified ribonucleotides by mass spectrometry (Data-independent acquisition)

Over 170 post-transcriptional RNA modifications have been described and are common in all kingdoms of life. These modifications range from methylation to complex chemical structures, with methylation being the most abundant. RNA modifications play a key role in RNA folding and function and their ...

MetabolomicsLipidIN: a comprehensive repository for flash platform-independent identification and reverse lipidomics

We present expeditious querying, reliable and platform-independent lipid annotation software LipidIN, a comprehensive lipidome atlas with tandem mass spectrometry information, relative retention time and reverse mass spectrometry information. Five-levels spectral fragmentations trees were formula...

MetabolomicsBone loss with aging is independent of gut microbiome in mice.

Emerging evidence suggests a significant role of gut microbiome in bone health. Aging is well recognized as a crucial factor influencing the gut microbiome. In this study, we investigated whether age-dependent microbial change contributes to age-related bone loss in CB6F1 mice. The bone phenotype...

MetabolomicsCustomized Consensus Spectral Library Building for Untargeted Quantitative Metabolomics Analysis with Data Independent Acquisition Mass Spectrometry and MetaboDIA Workflow
Data independent acquisition-mass spectrometry (DIA-MS) coupled with liquid chromatography is a promising approach for rapid, automatic sampling of MS/MS data in untargeted metabolomics. However, wide isolation windows in DIA-MS generate MS/MS spectra containing a mixed population of fragment ions t...

MetabolomicsA novel strategy for mining and identification of acylcarnitines using data-independent-acquisition (DIA) based retention time prediction modeling and pseudo-characteristic fragmentation ions matching
It is a challenging work to screen, identify, and quantify acylcarnitines in complex biological samples. A method, based on the retention time (RT) prediction and data-independent acquisition strategies, was proposed for the large-scale identification of acylcarnitines using liquid chromatography co...

MetabolomicsMitochondrial glutamine import sustains mitochondrial translation independent of glutaminolysis in cancer_GlnFlux_untargeted metabolites

Oxidative phosphorylation (OXPHOS) fulfills energy metabolism and biosynthesis through tricarboxylic acid (TCA) cycle and an intact electron transport chain (ETC). Mitochondrial glutamine import (MGI) replenishes TCA cycle through glutaminolysis, but its broader roles in cancer remains unclear. H...

MetabolomicsDeep Characterisation of the sn-Isomer Lipidome Using High-Throughput Data-Independent Acquisition and Ozone-Induced Dissociation

We report a workflow that enables untargeted characterization of hundreds of sn-resolved glycerophospholipid isomers from biological extracts in less than 20 min. It reveals that sn-isomer populations are tightly regulated and significantly different between cell lines and enables identification ...
