TVP1022, a non-MAO inhibitor S-isomer of rasagiline, possesses antioxidative and antiapoptotic activities. The current study examines the effects of TVP1022 and tempol on iAKI in diabetic rats. Diabetes was induced by streptozotocin. iAKI was induced by clamping the left renal artery for 30 min in both diabetic and nondiabetic rats. The right intact kidney served as a control. Forty-eight hours following ischemia, urinary flow (V), sodium excretion (UNaV), and glomerular filtration rate (GFR) in both ischemic and nonischemic kidneys were determined. The nephroprotective effects of tempol and TVP1022 were examined in these rats. Hematoxylin and eosin staining, 4-hydroxynonenal (4-HNE) immunofluorescence, and nitrotyrosine immunohistochemistry were performed on renal tissues of the various experimental groups. Compared with normoglycemic rats, iAKI in diabetic animals caused more profound reductions in V, UNaV, and GFR. Tempol and TVP1022 treatment increased GFR two- and four-fold in diabetic ischemic kidney, respectively. Besides hemodynamic perturbations, iAKI markedly increased renal immunoreactive 4-HNE and nitrotyrosine staining in both diabetic and nondiabetic rats. Moreover, iAKI increased medullary necrosis, congestion, and casts. Noteworthy, these increases were to a larger extent in ischemic diabetic kidneys. TVP1022, and to a lesser extent tempol, decreased nitrotyrosine and 4-HNE immunoreactivities and necrosis and cast formation in the renal medulla. TVP1022 treatment improves renal dysfunction and histological changes in an iAKI diabetic model and suggests a role for TVP1022 therapy in kidney injury. <\/jats:p>","DOI":"10.1152\/ajprenal.00379.2013","type":"journal-article","created":{"date-parts":[[2013,11,6]],"date-time":"2013-11-06T21:36:04Z","timestamp":1383773764000},"page":"F24-F33","source":"Crossref","is-referenced-by-count":11,"title":["Nephroprotective effects of TVP1022, a non-MAO inhibitor <i>S<\/i>-isomer of rasagiline, in an experimental model of diabetic renal ischemic injury"],"prefix":"10.1152","volume":"306","author":[{"given":"Niroz","family":"Abu-Saleh","sequence":"first","affiliation":[{"name":"Department of Physiology and Biophysics, Faculty of Medicine, Technion, IIT, Haifa, Israel;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hoda","family":"Awad","sequence":"additional","affiliation":[{"name":"Department of Physiology and Biophysics, Faculty of Medicine, Technion, IIT, Haifa, Israel;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mogher","family":"Khamaisi","sequence":"additional","affiliation":[{"name":"Institute of Endocrinology, Diabetes, and Metabolism and Internal Medicine C, Technion, IIT, Haifa, Israel;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zaher","family":"Armaly","sequence":"additional","affiliation":[{"name":"Nephrology Department, EMMS Nazareth-The Nazareth Hospital, Nazareth, Israel;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tony","family":"Karram","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, Rambam Health Campus, Haifa, Israel;"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Samuel N.","family":"Heyman","sequence":"additional","affiliation":[{"name":"Department of Medicine, Hadassah Hebrew University Hospital, Jerusalem, Israel;
