MetabolomicsMultiple omics reveal link between the microbiota-gut-brain axis and intracranial aneurysm rupture

Intracranial aneurysms (IAs) are benign cerebrovascular maladies characterized by pathological dilatation in the walls of intracranial arteries. However, spontaneous subarachnoid hemorrhage (SAH) resulting from aneurysm rupture poses a grave threat to the patient's life. Accumulating evidence imp...

ProteomicsReal-time library search assisted identification of cross-links increases resolution for structural modeling and interactome mapping
Cross-linking mass spectrometry (XL-MS) is a universal tool of molecular and structural biology for probing structural dynamics and protein-protein interactions in vitro and in vivo. Although cross-linked peptides are naturally less abundant than their unlinked counterparts, recent experimental adva...

ProteomicsExpanding the depth and sensitivity of cross-link identification by differential ion mobility using FAIMS
In cross-linking mass spectrometry (XL-MS), the depth and sensitivity of cross-link detection is often limited by the low abundance of cross-links compared to non-cross-linked peptides in the digestion mixture. To improve the identification efficiency of cross-links, here we present a gas-phase sepa...

MetabolomicsIntegrated Gut Microbiome and Metabolomics Analysis Reveals Microbial-Metabolic Cross-talk in Allergic Rhinitis

Background: Emerging evidence indicates a link between gut dysbiosis and allergic rhinitis (AR) pathogenesis. Nevertheless, the mechanistic role of gut microbiota in AR progression requires further characterization. To address this, we employed an integrated multi-omics strategy to delineat...

ProteomicsCharacterizing protein conformers by cross-linking mass spectrometry and pattern recognition
Motivation: Chemical cross-linking coupled to mass spectrometry (XLMS) emerged as a powerful technique for studying protein structures and large-scale protein-protein interactions. Nonetheless, XLMS lacks software tailored toward dealing with multiple conformers; this scenario can lead to high-quali...

ProteomicsCross-link assisted spatial proteomics to map sub-organelle proteomes and membrane protein topology
The specific functions of cellular organelles and sub-compartments depend on their protein content, which can be characterized by spatial proteomics approaches. However, many spatial proteomics methods are limited in their ability to resolve organellar sub-compartments, profile multiple sub-compartm...

ProteomicsNon-covalently associated peptides are observed during liquid chromatography-mass spectrometry and affect cross-link analyses
Cross-Linking/mass spectrometry draws structural information out of covalently linked peptide pairs. When these links do not match to previous structural models they may indicate changes of protein conformation. Unfortunately, such links can also be the result of experimental errors or artefacts. He...

ProteomicsKinetic principles of chemical cross-link formation for protein-protein interactions
Proteins play a central role in most biological processes within the cell and deciphering how they interact is key to understand their function. Cross-linking coupled to mass spectrometry is an essential tool for elucidating protein-protein interactions. Despite its importance, we still know surpris...

ProteomicsCross-linking mass spectrometry analyses of three different kinetochore protein complexes (KMN, NDC80C, MIS12C) using an MS-cleavable cross-linker, BuUrBu (DSBU)
In order to develop a simplified cross-linking mass spectrometry protocol, we applied one-step size-exclusion chromatography (SEC) for peptide purification after proteolysis with Lys-C and trypsin. Three benchmark protein complexes (KMN, NDC80C, MIS12C) from human kinetochore were cross-linked with ...
