Summary: This study compares four commonly used DDA library-free approaches for analyzing phosphoproteomics and ubiquitinomics DIA MS data, revealing Spectronaut's directDIA as the top performer for phosphopeptide detection and an in silico-predicted library based on DIA-NN as the best option for ubiquitinomics diaPASEF data analysis.

Summary: Thyroid nodules are common in about 60% of the population. Differentiating between follicular adenoma (FA) and carcinoma (FTC) is a challenge in thyroid nodule diagnosis. This study presents a comprehensive thyroid spectral library and identifies nine proteins that could potentially distinguish FA and FTC.

Summary: Data-independent acquisition-mass spectrometry (DIA-MS) is the method of choice for deep, consistent, and accurate single-shot profiling in bottom-up proteomics. Library-free approaches based on in silico prediction promise deep DIA-MS profiling with reduced experimental effort and cost, but coverage and sensitivity in such analyses are limited.

Summary: High-grade serous ovarian carcinoma (HGSOC) is a common subtype of ovarian cancer with low survival rates. Neoadjuvant chemotherapy (NACT) followed by interval debulking surgery (IDS) is recommended for advanced-stage HGSOC patients. However, a significant number of patients exhibit chemoresistance with unknown mechanisms.

Summary: This study presents an open-source NextFlow pipeline, nf-encyclopedia, which connects three open-source tools (MSConvert, EncyclopeDIA, and MSstats) for analyzing DIA proteomics experiments with or without chromatogram libraries. The pipeline is reproducible and provides robust peptide and protein quantification. MSstats improves protein-level quantification performance over EncyclopeDIA alone.

Summary: This article introduces a spectral library search tool called Calibr for spectrum-centric DIA data analysis. Calibr improves the number of spectrum-spectrum matches and peptides compared to traditional preprocessing methods. When compared to DDA and MassIVE spectral libraries, Calibr also demonstrates higher sensitivity.

Summary: The study presents a sample size-comparable library-based DIA approach, achieving higher protein group identification from small-size library compared to medium-size, large-size, and lung cancer resource spectral library. The approach shows good generality across different instruments and data analysis methods.

Summary: Sequential window acquisition of all theoretical mass spectra-mass spectrometry, supported by advanced bioinformatics, provides a comprehensive framework for proteome analysis and biomarker discovery. However, the lack of a generic sample preparation platform for heterogeneous materials from different sources limits its broad application. We developed universal and fully automated workflows using a robotic sample preparation platform, enabling in-depth and reproducible proteome coverage of bovine and ovine specimens. The high correlation between sheep proteomics and transcriptomics datasets validates this development and suggests the potential for various clinical applications across different animal species and disease models.

Summary: This study established a gas-phase fractionation (GPF) workflow for creating DIA libraries. The GPF workflow outperformed the traditional ddaPASEF workflow in identifying and quantifying proteins in plasma samples from nonsmall cell lung cancer patients. Overall, the choice of DIA library workflow had a limited effect on the overall outcome of a plasma proteomics experiment, but it did affect the number of proteins identified and the total experiment time.

Summary: Currently, mass spectrometry-based data-dependent acquisition protocols require significant amounts of proteins and complex protocols to identify low abundant proteins. Data-independent acquisition (DIA) approach allows identification of numerous proteins irrespective of their abundance, making it important for studying biological systems where protein availability is limited. In this study, a spectral library for Mycobacterium tuberculosis proteome was generated using publicly available proteomic data sets, providing a valuable resource for researchers studying M. tuberculosis using DIA approaches.

Summary: Sample multiplexed quantitative proteomics assays have improved instrument efficiency and quantitative accuracy through the development of intelligent data acquisition (IDA) strategies. The implementation of a real-time spectral library searching (RTLS) workflow enables intelligent scan triggering and peak selection in milliseconds, leading to improved quantitation of multiplexed samples. The RTLS method expands the IDA toolbox and allows for more efficient and accurate analysis of molecular phenotypes.

Summary: Mass spectrometry-based profiling of the phosphoproteome is a powerful method for identifying phosphorylation events. This Perspective reviews recent studies comparing data-dependent acquisition (DDA) and data-independent acquisition (DIA) methods for phosphoproteomics and discusses data analysis options. The analysis of a phosphopeptide-enriched data set shows that DDA identifies more unique phosphopeptides, while DIA provides more consistent identifications across replicates. Challenges include identifying coeluting phosphopeptide isomers and reproducibly locating high-confidence phosphorylation sites.
