In endothelial cell culture, simple sugars effectively impair mechanosensor proteins. To study mechanosensor\u2010 and vascular function in humans, 12 young healthy male subjects supplemented their diet with 3\u00a0\u00d7\u00a075\u00a0g sucrose day<jats:sup>\u22121<\/jats:sup> for 14\u00a0days in a randomized cross\u2010over design. Before and after the intervention period, the hyperaemic response to passive lower leg movement and active knee extensor exercise was determined by ultrasound doppler. A muscle biopsy was obtained from the thigh muscle before and after acute passive leg movement to allow assessment of protein amounts and the phosphorylation status of mechanosensory proteins and NADPH oxidase. The sucrose intervention led to a reduced flow response to passive movement (by 17\u00a0\u00b1\u00a02%) and to 12\u00a0W of active exercise (by 9\u00a0\u00b1\u00a01%), indicating impaired vascular function. A reduced flow response to passive and active exercise was paralleled by a significant up\u2010regulation of platelet endothelial cell adhesion molecule (PECAM\u20101), endothelial nitric oxide synthase, NADPH oxidase and the Rho family GTPase Rac1 protein expression in the muscle tissue, as well as an increased basal phosphorylation status of vascular endothelial growth factor receptor 2 and a reduced phosphorylation status of PECAM\u20101. The phosphorylation status was not acutely altered with passive leg movement. These findings indicate that a regular intake of high levels of sucrose can impair vascular mechanotransduction and increase the oxidative stress potential, and suggest that dietary excessive sugar intake may contribute to the development of vascular disease.<\/jats:p><\/jats:sec>","DOI":"10.1113\/jp274623","type":"journal-article","created":{"date-parts":[[2017,6,16]],"date-time":"2017-06-16T03:52:41Z","timestamp":1497585161000},"page":"5557-5571","source":"Crossref","is-referenced-by-count":20,"title":["Endothelial mechanotransduction proteins and vascular function are altered by dietary sucrose supplementation in healthy young male subjects"],"prefix":"10.1113","volume":"595","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0382-2523","authenticated-orcid":false,"given":"Lasse","family":"Gliemann","sequence":"first","affiliation":[{"name":"Section for Integrative Physiology University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7885-5653","authenticated-orcid":false,"given":"Nicolai","family":"Rytter","sequence":"additional","affiliation":[{"name":"Section for Integrative Physiology University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5940-4072","authenticated-orcid":false,"given":"Mads","family":"Lindskrog","sequence":"additional","affiliation":[{"name":"Section for Integrative Physiology University of Copenhagen  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martina H.
