The HEK293T cell line model has gained considerable attention from the scientific community, particularly in the fields of engineering and drug delivery. Nevertheless, there is a dearth of systematic comparisons of the most prevalent EV isolation methodologies for HEK293T in terms of recovery and specificity. In this study, common EV isolation workflows using either ultracentrifugation (UC), ultrafiltration (UF), polyethylene glycol precipitation (PEG), or EXODUS were compared in HEK293T cells and profiled using proteomics, which enabled the identification of almost 4000 proteins. Moreover, the observed large discrepancy between PEG and other methods can be attributed to the cofractionation of two EV populations that differed in density and protein composition, as revealed by isopycnic ultracentrifugation. Therefore, it was assumed that the cargo inside EVs is correlated with their density, which presents intrinsic heterogeneity in HEK293T EVs.

Furthermore, developmental transcriptomics highlighted that microtubule- and microfilament-related SMPs were enriched in larvae and adults, respectively, potentially reflecting differences in cytoskeletal regulation associated with larval aragonitic and adult calcitic shells. Transcriptomic analyses revealed that acidifying stress significantly downregulated the expression of genes encoding collagen and stress-fiber-related proteins, while activating the BMP signaling pathway in oysters.

Using LC–MS/MS, proteomes from 100 whole blood samples of known sex were analyzed to develop a biological sex classifier.

In this study, we focused on the chromatographic aspect and, more specifically, systematically evaluated proteome analysis performance across a wide range of chromatographic flow rates (0.3–50 μL/min) and associated column diameters using a Vanquish Neo HPLC coupled online to a Q Exactive HF-X mass spectrometer. Serial dilutions of HeLa cell line digests were used for benchmarking, and the total analysis time from injection to injection was intentionally fixed at 60 min (24 samples per day). The three key messages of the study are that (i) all chromatographic flow rates are suitable for high-quality proteome analysis, (ii) capLC (1.5 μL/min) is a very robust, sensitive, and quantitative alternative to nLC for many applications, and (iii) showcased proteome, phosphoproteome, and drug proteome data provide sound empirical guidance for laboratories in selecting appropriate chromatographic flow rates and column diameters for their specific applications.</p>","PeriodicalId":48,"journal":{"name":"Journal of Proteome Research","volume":"24 10","pages":"4988–5000"},"PeriodicalIF":3.6,"publicationDate":"2025-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/pdf/10.1021/acs.jproteome.5c00327","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144991065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
