As an initial step for the global discovery of changes in the abundance of parotid salivary proteins in pSS, a pooled sample was compared to that from healthy control subjects by multidimensional protein identification technology (MudPIT). A total of 1246 proteins were identified by MudPIT. The abundance of 477 of these proteins did not change, 529 were only detected in either the pSS or HC sample, while 206 of these proteins were significantly upregulated \u2265 twofold and 34 were downregulated \u2264 0.5. Ingenuity Pathway Analyses of differentially expressed proteins identified by MudPIT resulted in the identification of 100 significant pathways. The same samples were quantified in parallel using RP MS. Fifty\u2010eight of 71 proteins identified by RP overlapped with MudPIT results. Five proteins were further analyzed by targeted label\u2010free quantification to confirm the similar relative differential expression observed by RP and MudPIT approaches. The present study supports the use of MS for global discovery and validation of marker proteins for improved and early diagnosis of pSS.<\/jats:p>","DOI":"10.1002\/pmic.201200208","type":"journal-article","created":{"date-parts":[[2012,8,8]],"date-time":"2012-08-08T02:33:12Z","timestamp":1344393192000},"page":"3113-3120","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":40,"title":["Quantitative proteomics of parotid saliva in primary Sj\u00f6gren's syndrome"],"prefix":"10.1002","volume":"12","author":[{"given":"Kiran S.","family":"Ambatipudi","sequence":"first","affiliation":[{"name":"Secretory Mechanisms and Dysfunction Section National Institute of Dental and Craniofacial Research National Institutes of Health  Bethesda MD USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Stephen","family":"Swatkoski","sequence":"additional","affiliation":[{"name":"Proteomics Core Facility National Heart Lung and Blood Institute National Institutes of Health  Bethesda MD USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James J.","family":"Moresco","sequence":"additional","affiliation":[{"name":"Department of Chemical Physiology The Scripps Research Institute  La Jolla CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patricia G.","family":"Tu","sequence":"additional","affiliation":[{"name":"Department of Chemical Physiology The Scripps Research Institute  La Jolla CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreea","family":"Coca","sequence":"additional","affiliation":[{"name":"Department of Medicine Division of Allergy, Immunology, and Rheumatology University of Rochester Medical Center Rochester NY USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer H.","family":"Anolik","sequence":"additional","affiliation":[{"name":"Department of Medicine Division of Allergy, Immunology, and Rheumatology University of Rochester Medical Center Rochester NY USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marjan","family":"Gucek","sequence":"additional","affiliation":[{"name":"Proteomics Core Facility National Heart Lung and Blood Institute National Institutes of Health  Bethesda MD USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ig\u00f1acio","family":"Sanz","sequence":"additional","affiliation":[{"name":"Department of Medicine Division of Allergy, Immunology, and Rheumatology University of Rochester Medical Center Rochester NY USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"III","given":"John R.","family":"Yates","sequence":"additional","affiliation":[{"name":"Department of Chemical Physiology The Scripps Research Institute  La Jolla CA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James E.","family":"Melvin","sequence":"additional","affiliation":[{"name":"Secretory Mechanisms and Dysfunction Section National Institute of Dental and Craniofacial Research National Institutes of Health  Bethesda MD USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,9,10]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(05)66990-5"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.7326\/0003-4819-89-6-888"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.5507\/bp.2009.017"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1002\/art.22954"},{"key":"e_1_2_7_6_1","first-page":"203","article-title":"Sj\u00f6gren's syndrome in rheumatoid arthritis and progressive systemic sclerosis.
