Afterward, Label-free proteomics and LC-MS/MS metabolomics assays were combined to reveal differential abundant proteins and metabolites of TM4 cells infected with bvfA-deletion strains and parental strains. Finally, PRM mass spectrometry and western blot analysis were carried out to confirm differential expression of proteins.Results: This report demonstrated that bvfA-deletion strains failed to invade TM4 cells and reconstitution of invasion when a strain with gene bvfA was reintroduced to the deletion strain in 3 h. The bvfA-deletion exhibited weakened intracellular multiplication compared with parental strains in TM4 cells in 12 h; however, the death rate of TM4 cells infected with bvfA-deletion strains was higher than that of TM4 cells infected with parental strains. Combined proteomics and metabolomics analyses revealed that the differential abundant proteins and metabolites in TM4 cells infected with bvfA-deletion and parental strains mainly involved the mineral absorption-related pathway, NADH:ubiquinone oxidoreductase subunit-related mitochondrial respiratory signaling pathway, and sphingolipid signaling pathway of TM4 cells. These three signaling pathways were involved in expression changes of TRPM6/7, STEAP1, Gnaq, Trp53, Pbk, Tns2, Akt2, and the NADH:ubiquinone oxidoreductase subunit, as well as content changes of l-Valine, l-Isoleucine, l-Methionine, PC, PE DG, and SM metabolites.Significance: These results indicated that BvfA of Brucella abortus S19 affected the above proteins and metabolites in TM4 cells.","PeriodicalId":20571,"journal":{"name":"PROTEOMICS – Clinical Applications","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142605901","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fifteen proteins, which were especially related to immune response, insulin resistance, and lipid metabolism, were significantly different between patients without DSPN and with MSLFN. Besides, seven proteins, especially related to extracellular structure organization, were significantly different between serum from patients with SFN and with MSLFN.

After UPR induction, the proteome of the cells was modified with a greater adaptive response to cellular stress in CCL-221 cells where the UPR was strongly activated at the basal state.Conclusions and clinical relevance: CRC cell lines at different tumour grades expressed different functional programmes at the proteomic level and were characterised by different responses to the UPR induction.

Exposure to these redox-reactive compounds induces stress response in Mtb, which can affect posttranslational modifications (PTM).Methods: Here, we present the global analysis of the PTM acylation of Mtb proteins in response to a sublethal dose of nitrosative stress in the form of nitric oxide (NO) using label free quantification.Results: A total of 6437 acylation events were identified on 1496 Mtb proteins, and O-acylation accounted for 92.2% of the events identified, while 7.8% were N-acylation events. About 22% of the sites identified were found to be acylated by more than one acyl-group. Furthermore, the abundance of each acyl-group decreased as their molecular weight increased. Quantitative PTM analysis revealed differential abundance of acylation in proteins involved in stress response, iron ion homeostasis, growth, energy metabolism, and antimicrobial resistance (AMR) induced by nitrosative stress over time.Conclusions: The results reveal a potential role of Mtb protein acylation in the bacterial stress responses and AMR. To our knowledge, this is the first report on global O-acylation profile of Mtb in response to NO. This will significantly improve our understanding of the changes in Mtb acylation under nitrosative stress, highly relevant for global health.","PeriodicalId":20571,"journal":{"name":"PROTEOMICS – Clinical Applications","volume":null,"pages":null},"PeriodicalIF":2.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141856252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This pioneering proteomic study conducted a comparative profiling of milk somatic cell (SC) proteins contributing to mammary immune defense during subclinical and clinical mastitis (CM) in Sahiwal (Bos indicus) cows.Experimental design: Based on California mastitis test (CMT) scores, milk SC counts, differential leukocyte counts (DLCs), and bacteriological culture results, quarter milk SC samples were categorized into healthy (H), subclinical mastitis (SCM), and CM groups. Comparative proteome profiling of milk SCs was done using a label-free liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) proteomic approach.Results: The identified upregulated proteins in mastitis groups such as Vanin 2, Thioredoxin reductase-like selenoprotein T, Ceramidase, Lymphocyte antigen 75, Misshapen-like kinase 1 (MINK1), Thrombospondin 1, Macrophage scavenger receptor 1, Leupaxin, and Lipoamide acyltransferase, involved in immune responses.
