Because the risk of PE is actually decreased by cigarette smoking, we considered the possibility that nicotine, a critical component of tobacco smoke, might protect against PE by modifying the content of exosomes from EVTs. We investigated the effects of nicotine on our PE model mouse and evaluated blood pressure. Next, exosomes were extracted from nicotine-treated extravillous trophoblasts (HTR-8\/SVneo), and the peptide samples were evaluated by DIA (Data Independent Acquisition) proteomic analysis following nano LC-MS\/MS. Hub proteins were identified using bioinformatic analysis. We found that nicotine significantly reduced blood pressure in a PE mouse model. Furthermore, we identified many proteins whose abundance in exosomes was modified by nicotine treatment of EVTs, and we used bioinformatic annotation and network analysis to select five key hub proteins with potential roles in the pathogenesis or prevention of PE. EVT-derived exosomes might influence the pathogenesis of PE because the cargo delivered by exosomes can signal to and modify the receiving cells and their environment.<\/jats:p>","DOI":"10.3390\/ijms241311126","type":"journal-article","created":{"date-parts":[[2023,7,6]],"date-time":"2023-07-06T00:34:30Z","timestamp":1688603670000},"page":"11126","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Influence of Nicotine on Trophoblast-Derived Exosomes in a Mouse Model of Pathogenic Preeclampsia"],"prefix":"10.3390","volume":"24","author":[{"given":"Ayane","family":"Kubo","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Ehime University Graduate School of Medicine, Shitsukawa, Toon 791-0295, Ehime, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7488-8837","authenticated-orcid":false,"given":"Keiichi","family":"Matsubara","sequence":"additional","affiliation":[{"name":"Department of Regional Pediatrics and Perinatology, Ehime University Graduate School of Medicine, Shitsukawa, Toon 791-0295, Ehime, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuko","family":"Matsubara","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Ehime University Graduate School of Medicine, Shitsukawa, Toon 791-0295, Ehime, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hirotomo","family":"Nakaoka","sequence":"additional","affiliation":[{"name":"Advanced Research Support Center, Ehime University Graduate School of Medicine, Shitsukawa, Toon 791-0295, Ehime, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Sugiyama","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Ehime University Graduate School of Medicine, Shitsukawa, Toon 791-0295, Ehime, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"S38","DOI":"10.1016\/j.placenta.2008.11.021","article-title":"Placental stress and pre-eclampsia: A revised view","volume":"30","author":"Redman","year":"2009","journal-title":"Placenta"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"S32","DOI":"10.1016\/j.placenta.2008.11.009","article-title":"The two stage model of preeclampsia: Variations on the theme","volume":"30","author":"Roberts","year":"2009","journal-title":"Placenta"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1007\/s11906-018-0828-4","article-title":"The Endothelin System: A Critical Player in the Pathophysiology of Preeclampsia","volume":"20","author":"Granger","year":"2018","journal-title":"Curr.
