However, the mechanisms underlying pathogenesis of salt- and fructose-induced kidney damage and\/or consequent hypertension yet remain largely unexplored. Here, we tested the role of oxidative state as an essential factor along with high salt and fructose treatment in causing hypertension. Fischer male rats were supplemented with a high-fructose diet (20% in water) for 20 weeks and maintained on high-salt diet (8%) associate in the last 10 weeks. Fructose-fed rats exhibited a salt-dependent hypertension accompanied by decrease in renal superoxide dismutase activity, which is the first footprint of antioxidant inactivation by reactive oxygen species (ROS). Metabolic changes and the hypertensive effect of the combined fructose-salt diet (20 weeks) were markedly reversed by a superoxide scavenger, Tempol (10\u2009mg\/kg, gavage); moreover, Tempol (50\u2009mM) potentially reduced ROS production and abolished nuclear factor-kappa B (NF-\u03baB) activation in human embryonic kidney HEK293 cells incubated with L-fructose (30\u2009mM) and NaCl (500 mosmol\/kg added). Taken together, our data suggested a possible role of oxygen radicals and ROS-induced activation of NF-\u03baB in the fructose- and salt-induced hypertension associated with the progression of the renal disease.<\/jats:p>","DOI":"10.1038\/srep46051","type":"journal-article","created":{"date-parts":[[2017,4,11]],"date-time":"2017-04-11T09:22:20Z","timestamp":1491902540000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["Oxidative stress causes hypertension and activation of nuclear factor-\u03baB after high-fructose and salt treatments"],"prefix":"10.1038","volume":"7","author":[{"given":"Waleska C.","family":"Dornas","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Leonardo M.","family":"Cardoso","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ma\u00edsa","family":"Silva","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nat\u00e1lia L.
