Abstract Proteins in the plasma/serum mirror an individual’s physiology. Circulating extracellular vesicles (EVs) proteins constitute a large portion of proteome. Thus, deep and unbiased proteomic analysis circulating holds promise for discovering disease biomarkers as well revealing mechanisms. We established workflow simple, deep, reproducible proteome both serum small EVs enriched fractions by ultracentrifugation plus 4D-data-independent acquisition mass spectrometry (4D-DIA-MS). In our cohort study obstetric antiphospholipid syndrome (OAPS), 4270 3328 were identified from respectively. Both them revealed known or new pathways related to OAPS. Increased levels von Willebrand factor (VWF) insulin receptor (INSR) candidate biomarkers, which shed light on hypercoagulability abnormal signaling progression. Our will significantly promote understanding plasma/serum-based mechanisms generate biomarkers.

Abstract Increased throughput in proteomic experiments can improve accessibility of platforms, reduce costs, and facilitate new approaches systems biology biomedical research. Here we propose combination analytical flow rate chromatography with ion mobility separation peptide ions, data‐independent acquisition, data analysis the DIA‐NN software suite, to achieve high‐quality from limited sample amounts, at a up 400 samples per day. For instance, when benchmarking our workflow using 500‐μL/min 3‐min chromatographic gradients, report quantification 5211 proteins 2 μg mammalian cell‐line standard high quantitative accuracy precision. We further used this platform analyze blood plasma cohort COVID‐19 inpatients, gradient alternating column regeneration on dual pump system. The method delivered comprehensive view proteome, allowing classification patients according disease severity revealing biomarker candidates.

Abstract COVID-19 is characterised by systemic immunological perturbations in the human body, which can lead to multi-organ damage. Many of these processes are considered be mediated blood. Therefore, better understand host response SARS-CoV-2 infection, we performed systematic analyses circulating, soluble proteins blood through global proteomics mass-spectrometry (MS) proteomics. Here, show that a large part proteome altered COVID-19, among them elevated levels interferon-induced and proteasomal proteins. Some have alternating cells after infection vitro different organs patients deregulated blood, suggesting shared infection-related changes.The availability public proteomic resources on alterations leaves uncertainty about change given protein during COVID-19. Hence, review meta-analysis MS studies proteomes, including up 1706 individuals (1039 patients), provide concluding estimates for alteration 1517 Finally, based developed CoViMAPP, an open-access resource effect sizes diagnostic potential publicly available research, clinical, academic community.

Abstract Biomarkers for early detection of breast cancer may complement population screening approaches to enable earlier and more precise treatment. The blood proteome is an important source biomarker discovery but so far, few proteins have been identified with risk. Here, we measure 2929 unique in plasma from 598 women selected the Karolinska Mammography Project explore association between protein levels, clinical characteristics, gene variants, identify a causal role cancer. We present 812 cis-acting quantitative trait loci 737 which are used as instruments Mendelian randomisation analyses Of those, five (CD160, DNPH1, LAYN, LRRC37A2 TLR1) that show potential risk confirmatory results independent cohorts. Our study suggests these should be further explored biomarkers drug targets

Recent improvements in proteomics technologies have fundamentally altered our capacities to characterize human biology. There is an ever-growing interest using these novel methods for studying the circulating proteome, as blood offers accessible window into health. However, every methodological innovation and analytical progress calls reassessing existing approaches routines ensure that new data will add value greater biomedical research community avoid previous errors. As representatives of HUPO's Human Plasma Proteome Project (HPPP), we present 2024 survey current community, including latest build PeptideAtlas now comprises 4608 proteins detected 113 sets.

Major depressive disorder (MDD) is characterized by persistent feelings of sadness and loss interest. Ketamine has been widely used to treat MDD owing its rapid effect in relieving symptoms. Importantly, not all patients respond ketamine treatment. Identifying sub-populations who will benefit from ketamine, as well those may not, prior treatment initiation, would significantly advance precision medicine with MDD. Here, we mass spectrometry-based plasma proteomics analyze matched pre- post-ketamine samples a cohort 30 whose outcomes demographic clinical characteristics were considered. responders non-responders identified according their individual after two weeks We analyzed proteomic alterations post-treatment collection six proteins pivotal the antidepressive ketamine. Subsequent co-regulation analysis revealed that pathways related immune response involved response. By comparing profiles same individuals at time points, dynamic rearrangements induced immune-related processes activated association effect. Furthermore, receiver operating characteristic curve pre-treatment three strong predictive performance determining before receiving These findings provide valuable knowledge about response, which ultimately lead more personalized effective treatments for patients.

Abstract Extracellular vesicles play major roles in cell-to-cell communication and are excellent biomarker candidates. However, studying plasma extracellular is challenging due to contaminants. Here, we performed a proteomics meta-analysis of public data refine the EV composition by separating proteins contaminants into different clusters. We obtained two clusters with total 1717 that were depleted known enriched markers independently validated 71% true-positive. These had 133 differentiation (CD) antigens from signaling. compared our deposited PeptideAtlas, making refined protein list resource for mechanistic studies. As use case example this resource, type 1 diabetes proplatelet basic EVs showed it regulates apoptosis β cells macrophages, key players disease development. Our approach provides refinement scientific community.

Abstract Alzheimer’s disease (AD) and related dementias (ADRD) is a complex with multiple pathophysiological drivers that determine clinical symptomology progression. These diseases develop insidiously over time, through many pathways mechanisms continue to have huge societal impact for affected individuals their families. While emerging blood-based biomarkers, such as plasma p-tau181 p-tau217, accurately detect Alzheimer neuropthology are associated faster cognitive decline, the full extension of proteomic changes in ADRD remains unknown. Earlier detection better classification different subtypes may provide opportunities earlier, more targeted interventions, perhaps higher likelihood successful therapeutic development. In this study, we aim leverage unbiased mass spectrometry proteomics identify novel, biomarkers decline. 1,786 samples from 1,005 patients were collected 12 years partcipants Massachusetts Disease Research Center Longitudinal Cohort Study. Patient metadata includes demographics, final diagnoses, dementia rating (CDR) scores taken concurrently. The Proteograph TM Product Suite (Seer, Inc.) liquid-chromatography mass-spectrometry (LC-MS) analysis used process cohort generate data. Data-independent acquisition (DIA) results yielded 36,259 peptides 4,007 protein groups. Linear mixed effects models revealed 138 differentially abundant proteins between AD healthy controls. Machine learning diagnosis identified potential candidate including MBP, BGLAP, APoD.

Abstract Despite progress, MS-based proteomics in biofluids, especially blood, faces challenges such as dynamic range and throughput limitations biomarker disease studies. In this work, we used cutting-edge technologies to construct label-based label-free workflows, capable of quantifying approximately 2,000 proteins biofluids. With 70µL blood a single depletion strategy, conducted an analysis homogenous cohort ( n = 32), comparing medium-grade prostate cancer patients (Gleason score: 7(3 + 4); TNM stage: T2cN0M0, stage IIB) healthy donors. The results revealed dozens differentially expressed both plasma serum. We identified the upregulation Prostate Specific Antigen (PSA), well-known for cancer, serum cohort. Further bioinformatics highlighted noteworthy which appear be secreted into bloodstream, making them good candidates further exploration.
