The purpose of the present study was to assess the oxidative stress in VAT and vascular samples and the effect of in vitro administration of vitamin D. VAT and mesenteric artery branches were harvested during abdominal surgery performed on patients referred for general surgery (n = 30) that were randomized into two subgroups: nonobese and obese. Serum levels of C-reactive protein (CRP) and vitamin D were measured. Tissue samples were treated or not with the active form of vitamin D: 1,25(OH)<jats:sub>2<\/jats:sub>D<jats:sub>3<\/jats:sub> (100 nmol\/L, 12 h). The main findings are that in obese patients, (i) a low vitamin D status was associated with increased inflammatory markers and reactive oxygen species generation in VAT and vascular samples and (ii) in vitro incubation with vitamin D alleviated oxidative stress in VAT and vascular preparations and also improved the vascular function. We report here that the serum level of vitamin D is inversely correlated with the magnitude of oxidative stress in the adipose tissue. Ex vivo treatment with active vitamin D mitigated obesity-related oxidative stress. <\/jats:p>","DOI":"10.1139\/cjpp-2019-0340","type":"journal-article","created":{"date-parts":[[2019,9,23]],"date-time":"2019-09-23T21:37:49Z","timestamp":1569274669000},"page":"85-92","update-policy":"https:\/\/doi.org\/10.1139\/csp-crossmark-policy","source":"Crossref","is-referenced-by-count":24,"title":["Vitamin D alleviates oxidative stress in adipose tissue and mesenteric vessels from obese patients with subclinical inflammation"],"prefix":"10.1139","volume":"98","author":[{"given":"Mihaela","family":"Ionica","sequence":"first","affiliation":[{"name":"Department of Functional Sciences-Pathophysiology, University of Medicine and Pharmacy of Timi\u0326soara, Timi\u0326soara, Romania."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oana M.","family":"Aburel","sequence":"additional","affiliation":[{"name":"Department of Functional Sciences-Pathophysiology, University of Medicine and Pharmacy of Timi\u0326soara, Timi\u0326soara, Romania."},{"name":"Center for Translational Research and Systems Medicine, Faculty of Medicine, University of Medicine and Pharmacy of Timi\u0326soara, Timi\u0326soara, Romania."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adrian","family":"Vaduva","sequence":"additional","affiliation":[{"name":"Department of Anatomy, Physiology and Pathophysiology, Faculty of Pharmacy, University of Medicine and Pharmacy of Timi\u0326soara, Timi\u0326soara, Romania."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexandra","family":"Petrus","sequence":"additional","affiliation":[{"name":"Department of Microscopic Morphology-Morphopathology, University of Medicine and Pharmacy of Timi\u0326soara, Timi\u0326soara, Romania."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sonia","family":"Ra\u021biu","sequence":"additional","affiliation":[{"name":"Department of Surgery II, 1st Clinic of Surgery, Faculty of Medicine, University of Medicine and Pharmacy of Timi\u0326soara, Timi\u0326soara, Romania."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sorin","family":"Olariu","sequence":"additional","affiliation":[{"name":"Department of Surgery II, 1st Clinic of Surgery, Faculty of Medicine, University of Medicine and Pharmacy of Timi\u0326soara, Timi\u0326soara, Romania."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adrian","family":"Sturza","sequence":"additional","affiliation":[{"name":"Department of Functional Sciences-Pathophysiology, University of Medicine and Pharmacy of Timi\u0326soara, Timi\u0326soara, Romania."},{"name":"Center for Translational Research and Systems Medicine, Faculty of Medicine, University of Medicine and Pharmacy of Timi\u0326soara, Timi\u0326soara, Romania."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danina M.","family":"Muntean","sequence":"additional","affiliation":[{"name":"Department of Functional Sciences-Pathophysiology, University of Medicine and Pharmacy of Timi\u0326soara, Timi\u0326soara, Romania."},{"name":"Center for Translational Research and Systems Medicine, Faculty of Medicine, University of Medicine and Pharmacy of Timi\u0326soara, Timi\u0326soara, Romania."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"155","reference":[{"key":"refg1\/ref1","doi-asserted-by":"publisher","DOI":"10.1016\/0026-0495(86)90116-2"},{"key":"refg2\/ref2","doi-asserted-by":"publisher","DOI":"10.1016\/0026-0495(88)90041-8"},{"key":"refg3\/ref3","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCRESAHA.115.306825"},{"key":"refg4\/ref4","doi-asserted-by":"publisher","DOI":"10.1113\/expphysiol.2014.081414"},{"key":"refg5\/ref5","doi-asserted-by":"publisher","DOI":"10.1002\/cphy.c170040"},{"key":"refg6\/ref6","doi-asserted-by":"publisher","DOI":"10.1152\/physrev.00014.2015"},{"key":"refg7\/ref7","doi-asserted-by":"publisher","DOI":"10.3390\/nu10091199"},{"key":"refg8\/ref8","doi-asserted-by":"publisher","DOI":"10.1038\/nmeth.2075"},{"key":"refg9\/ref9","doi-asserted-by":"publisher","DOI":"10.1210\/jc.2016-3591"},{"key":"refg10\/ref10","doi-asserted-by":"publisher","DOI":"10.1017\/S0007114512003285"},{"key":"refg11\/ref11","doi-asserted-by":"publisher","DOI":"10.1155\/2016\/8470394"},{"key":"refg12\/ref12","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-48382-5_9"},{"key":"refg13\/ref13","doi-asserted-by":"publisher","DOI":"10.1007\/s10753-017-0610-9"},{"key":"refg14\/ref14","doi-asserted-by":"publisher","unstructured":"Filgueiras, M.S., Rocha, N.P., Novaes, J.F., and Bressan, J. 2018.
