However, the challenge in biological samples is the variability in relative concentrations (0.1%) of site-specific tyrosine phosphorylation on proteins. To navigate these fluctuations and accurately quantify the absolute levels of tyrosine phosphosites among different samples, we reported a hybrid data-independent acquisition-parallel reaction monitoring (DIA-PRM) MS technique for the robust identification and quantification of the phosphoproteome, the establishment of a comprehensive library of tyrosine phosphosites, and the specific assessment of changes in tyrosine phosphorylation. In our model study on non-small cell lung cancer cells, our PRM strategy accomplished by a spiked-in synthetic heavy phosphopeptide demonstrated reliable targeted quantification of the pY1197 on EGFR, revealing levels of 2.5, 4.9, and 5.3 fmol in pervanadate (PV)-treated cells at 0, 15, and 30 min, respectively. Additionally, DIA-extensive phosphoproteomic analysis provided 2765 tyrosine phosphosites within 14,961 global phosphosites corresponding to 1536 phosphoproteins, contributing to the phospho-library establishment and relative quantification of phosphorylation level, especially in the PV-treated time-dependent increase of ErbB signaling pathway. This hybrid DIA-PRM approach will advance the application of precise measurement of changes in multiple phosphotyrosine residues and enhance our understanding of phosphoproteomic dynamics in drug-resistant cascades.</p>","PeriodicalId":17262,"journal":{"name":"Journal of The Chinese Chemical Society","volume":null,"pages":null},"PeriodicalIF":1.6,"publicationDate":"2024-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141512650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
