We describe an improved version of the data-independent acquisition (DIA) computational analysis tool DIA-Umpire, and show that it enables highly sensitive, untargeted, and direct (spectral library-free) analysis of DIA data obtained using the Orbitrap family of mass spectrometers. DIA-Umpire v2 implements an improved feature detection algorithm with two additional filters based on the isotope pattern and fractional peptide mass analysis. The targeted re-extraction step of DIA-Umpire is updated ...[more]

LFQbench enables a multi-centered benchmark study demonstrating robust proteomic label-free quantification

Project description:The consistent and accurate quantification of proteins is a challenging task for mass spectrometry (MS)-based proteomics. SWATH-MS uses data-independent acquisition (DIA) for label-free quantification. Here we evaluated five software tools for processing SWATH-MS data: OpenSWATH, SWATH2.0, Skyline, Spectronaut, DIA-Umpire, in collaboration with the respective developers to ensure an optimal use of each tool. We analyzed data from hybrid proteome samples of defined quantitative composition acquired on two different MS instruments applying different SWATH isolation windows setups. Using the resulting high-complexity datasets we benchmarked precision and accuracy of quantification and evaluated identification performance, robustness and specificity of each software tool. To consistently evaluate the high complexity datasets, we developed the LFQbench R-package. LFQbench results enabled developers to improve their software tools, thereby underlining the value of the reference datasets for software development and benchmarking. All tools provided highly convergent identification and reliable quantification performance, underscoring their robustness for label-free quantitative proteomics.

DIA-Umpire: comprehensive computational framework for data independent acquisition proteomics

Project description:This dataset consists of 44 raw MS files, comprising 27 DIA (SWATH) and 15 DDA runs on a TripleTOF 5600 and of two raw mass spectrometry files acquired on a Q Exactive. The composition of the dataset is described in the manuscript by Tsou et al., titled: "DIA-Umpire: comprehensive computational framework for data independent acquisition proteomics", Nature Methods, in press Raw files are deposited here in ProteomeXchange and are associated with the DIA-Umpire processed data. All DIA-Umpire processed results for each sample together with DDA results are deposited in separated folders. Also see the "DataSampleID.xlsx" associated with this Readme file.

DIA acquisition of the immunopeptidomes of C1R-B*57:01 and C1R-A*02:01 cell lines

Project description:Immunopeptidomes are the peptide repertoires bound by the molecules encoded by the major histocompatibility complex (MHC) (human leukocyte antigen (HLA) in humans). These HLA-peptide complexes are presented on the cell surface for immune T cell recognition. Immunopeptidomics utilizes tandem mass spectrometry (MS/MS) to identify and quantify peptides bound to HLA molecules. Data-independent acquisition (DIA) has emerged as a powerful strategy for deep proteome-wide profiling, but DIA application to immunopeptidomics analyses has so far seen limited use. The dataset deposited here contains the DIA data of the HLA-bound peptides purified and isolated from C1R-B*57:01 and C1R-A*02:01 cell lines.

Comparison of Targeted MS Methods in Activity-Based Protein Profiling 2: DIA

Project description:To examine the different mass spectrometry approaches to monitoring kinases after enrichment with desthiobiotinylating probes for activity-based protein profiling (ABPP), two experiments were performed with H1993 lung cancer cells. First, cell lysates were pre-treated with DMSO vehicle, dasatinib, or erlotinib prior to addition of the ATP probe for ABPP to compare the differences in kinase labeling associated with examples of kinase inhibitors that vary in target selectivity. Then, to examine changes in cellular signaling, H1993 cells were treated with vehicle controls, BEX-235 (PI3K inhibitor), or Crizotinib. LC-MS/MS using data dependent acquisition, data-independent acquisition (pSMART), parallel reaction monitoring, and selected reaction monitoring (or multiple reaction monitoring) mass spectrometry were used to detect and relatively quantify the desthiobiotinylated kinase peptides.

Inference and quantification of peptidoforms in large sample cohorts by SWATH-MS: PTM-SWATH-MS Gold Standard data set

Project description:The PTM-SWATH MS Gold Standard data set consists of a previously published (Soste et al., 2014, PMID:25194849) set of 579 unpurified, synthetic, heavy-isotope labeled phosphopeptides (Thermo Scientific Biopolymers). These phosphopeptides represent biologically relevant sequences from S. cerevisiae proteins, which have been found altered in their phosphorylation status under various conditions. The complete peptide set contains a mixture of singly and doubly phosphorylated sequences with in average more than 3 modifiable residues per peptide (serines, threonines or tyrosins, often in close proximity to each other). All peptides were mixed with equal volumes (concentrations are unknown due to the unpurified status of the peptides) and the resulting peptide mix was either analyzed directly in DDA mode for assay library generation or spiked into a human cell line background proteome in a 13-step dilution series and analyzed in SWATH mode for the generation of the SWATH Gold Standard data set.

A microarray meta-dataset of pancreatic cancer

Project description:We present a meta-dataset comprising of a total of 178 samples including both primary tumors and tumor-free pancreatic tissues from four independent GEO datasets. To minimise inter-platform variation, only datasets generated from the GPL570 platform (Affymetrix Human Genome U133 Plus 2.0 Array) were processed to develop the meta-dataset. Using multiple open source R packages implemented in our previously developed bioinformatics pipeline, each dataset has been preprocessed with RMA normalisation, merged, and batch effect-corrected via Combat method. With increased sample size, the present meta-dataset serves an excellent 'discovery cohort' for discovering differentially expressed in diseased phenotype.
