Almost all algorithms for the identification of peptides in LC-MS/MS data employ two steps: peptide/spectrum matching and peptide-identity-propagation (PIP), also known as match-between-runs. PIP can routinely account for up to 40% of all results, with that proportion rising as high as 75% in single-cell proteomics. Unlike peptide identities derived through peptide/spectrum matches, for which error estimation has been strictly enforced for decades, peptide identities derived through PIP have not historically been subject to statistical evaluation. As an indispensable component of label-free quantification, PIP needs a statistically rigorous method for estimating its false-discovery rate (FDR). We present a method for FDR control of PIP, called PIP-ECHO, and devise a rigorous protocol for evaluating FDR control of any PIP method. Using three different benchmark data sets, we evaluate PIP-ECHO alongside the PIP procedures implemented by FlashLFQ, IonQuant, and MaxQuant. These analyses show that only PIP-ECHO can accurately control the FDR of PIP at 1% across all data sets. When analyzing a spike-in data set, PIP-ECHO increases both the accuracy and sensitivity of differential expression analysis, yielding substantially more differentially abundant proteins than either MaxQuant or IonQuant.</p>","PeriodicalId":48,"journal":{"name":"Journal of Proteome Research","volume":" ","pages":""},"PeriodicalIF":3.6,"publicationDate":"2025-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144740661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of high-throughput proteomics pipelines has led to the discovery of large numbers of phosphorylated protein motifs and sites (phosphosites) across many eukaryotic species.

Furthermore, only a small fraction of the characterized human phosphoproteome has an annotated functional role. A common way of predicting functional phosphosites is through conservation-based sequence analysis, but large-scale evolutionary studies are scarce. In this study, we explore the conservation of 20,751 confident human phosphosites across 100 eukaryotic species and investigate the evolution of associated protein domains and kinases. We categorize protein functions based on phosphosite conservation patterns and demonstrate the importance of conservation analysis in identifying organisms suitable as biological models for studying conserved signaling pathways relevant to human biology and disease. Finally, we use human protein sequences as a reference for propagating over 1,000,000 potential phosphosites to other eukaryotes.

ASNase is an enzyme-drug approved for the treatment of pediatric acute lymphoblastic leukemia (ALL) but too toxic for use in adults, making it an ideal test case. We collected 20-μL whole blood samples longitudinally, processed them to plasma, and extracted three molecule types (metabolites, lipids, and proteins) from each sample.

As a case study, we started with material available due to an infestation of a home with black widow spiders. Thanks to the recent publication of an annotated genome for one species of black widow spider, we were able to identify 5502 protein groups and assign putative annotations using ortholog mapping. We also demonstrate that had we not had this resource, over 2000 proteins could be identified using other available spider genome annotations, despite their unrelatedness. Moreover, regardless of the spider proteome used, proteins annotated as toxins were almost exclusively observed in the main body of the mature female black widow spider. Overall, these results provide a draft proteome map for the black widow spider and valuable data for validating machine learning models while also suggesting that the door to insightful quantitative proteomics may already be open for millions of less studied organisms.

In this study, we assessed the plasticity of the lipidomic profile of RBC from children with MCADD and controls using C18 liquid chromatography-mass spectrometry. The results revealed significant alterations in 240 lipid species in MCADD, highlighting an upregulation of sphingolipids (sphingomyelins and ceramides) and lysophospholipid species (lysophosphatidylcholines and lysophosphatidylethanolamines) alongside a downregulation of polyunsaturated and ether-linked phosphatidylcholines (PCs) and phosphatidylethanolamines (PEs). Also, altered PC/PE and (PC + SM)/(PE + PS) ratios could be associated with alterations in RBC membranes properties, e.g., fluidity and asymmetry. The observed changes in the lipidome suggest compromised antioxidant defenses, enhanced oxidative stress, and an inflammatory state, with potential systemic implications in MCADD lipid metabolism and long-term complications in older age.

Here, we report for the first time that periodontal bacteria actively interplay with HPV-driven head and neck cancer stem cells (CSCs) via the activation of signaling pathways mediated by small extracellular vesicles (sEVs), leading to the rapid enrichment of CSCs during HPV-driven HNC progression and development. We observed an upregulation of Mediator Complex Subunit 27 (MED27) in sEVs derived from periodontal bacteria-infected HPV-driven HNC, as evidenced by 4D-microDIA quantitative proteomics analysis. Meanwhile, the silencing of MED27 resulted in the suppression of migratory, invasive, and sphere-forming abilities of HPV-driven HNC cells. Subsequent clinical data analysis revealed that the elevated level of MED27 was significantly correlated with aggressive clinicopathologic features and shorter survival in HNC patients. Most importantly, MED27 was expressed at a higher mRNA level in HPV-driven HNC patients when compared to controls and non-HPV-driven HNC patients, suggesting its potential as a diagnostic biomarker for HPV-driven HNC.
