ProteomicsEasySCP Unveils Extensive Liver Zonation at Single-cell Proteomics Resolution
The widespread adoption of single-cell proteomics (SCP) in biology has been limited by complex workflows and reliance on specialized instrumentation. Here we present EasySCP, a high-throughput and lossless method that integrates FACS-based single-cell sorting, an all-in-one, single-step digestion pr...

MetabolomicsCell Membrane Remodeling Mediates Polymyxin B Resistance in Klebsiella pneumoniae: An Integrated Proteomics and Metabolomics Study
Polymyxin B (PB) is introduced into the clinic as the last-line therapy against carbapenem-resistant Klebsiella pneumoniae (CRKP). Unfortunately, increased resistance to PB in Klebsiella pneumoniae (K. pneumoniae) has threatened global health. Resistance of K. pneumoniae ...

MetabolomicsIntegrated proteome and lipidome analyses place OCIAD1 at mitochondria-peroxisome intersection balancing lipid metabolism

OCIAD1 (Ovarian Cancer Immunoreactive Antigen Domain Containing 1) is a membrane protein largely localized to mitochondria, however, its function in health or disease is not well understood. To comprehensively characterize the molecular changes upon lack of OCIAD1, we used mass spectrometry to st...

ProteomicsAn automated workflow for label-free and multiplexed single cell proteomics sample preparation at unprecedented sensitivity.
The analysis of single cell proteomes has recently become a viable complement to transcript and genomics studies. Proteins are the main driver of cellular functionality and mRNA levels are often an unreliable proxy of such. Therefore, the global analysis of the proteome is essential to study cellula...

ProteomicsLow-resolution FAIMS for increased peptide coverage in low-load and single-cell proteomics
Field Asymmetric Ion Mobility Spectrometry (FAIMS) is an indispensable tool in single-cell and low-input proteomics. Here, we show that tuning FAIMS resolution via electrode temperature modulation improves sensitivity. We demonstrate that lowering FAIMS resolution broadens the compensation voltage w...

MetabolomicsProteomics and tracer metabolomics link GAPDH ISGylation to glycolytic control

Ubiquitin-like protein ISG15 (interferon-stimulated gene 15) has been implicated in the regulation of central carbon metabolism, but conflicting findings across experimental systems have limited mechanistic insight. Here, we applied a multi-omics approach in cells ectopically expressing the ISGyl...

MetabolomicsLiquid chromatography coupled to high-resolution mass spectrometry metabolomics: A useful tool for investigating tumor secretome based on a three-dimensional co-culture model

Three-dimensional (3D) cell culture technologies, which more closely mimic the complex microenvironment of tissue, are being increasingly evaluated as a tool for the preclinical screening of clinically promising new molecules, and studying of tissue metabolism. Studies of metabolites released int...

MetabolomicsBiological Characteristics of SARS-CoV-2 Resistant Populations: A Cohort Comparison Study through Integrated Gut Microbiota Sequencing, Metabolomics and Proteomics

Objective: Most research reports on COVID-19 infections have focused on the correlation between the severity of the disease symptoms and immune deficits, while the mechanisms affecting the susceptibility to SARS-CoV-2 remain largely unknown. The study aimed to comprehensively analyze the differen...

ProteomicsA deeper look at carrier proteome effects for single-cell proteomics
We probe the carrier proteome effects in single cell proteomics with mixed species TMTpro-labeled samples. We demonstrate that carrier proteomes, while increasing overall identifications, dictate which proteins are identified. We show that quantitative precision and signal intensity are limited at h...
