Objective: We investigated the effects of angiotensin II (Ang II) type 1 (AT1) receptor blocker (ARB) olmesartan on impaired endothelial progenitor cells (EPCs) and renal degeneration through angiotensin converting enzyme 2 (ACE2)/ Ang-(1–7)/Mas receptor (MasR) axis in salt-loaded spontaneously hypertensive rats (SHRs).
Methods: Wistar-Kyoto/Izm (WKY) rats and SHR/Izm were salt-loaded. SHRs were treated with vehicle, hydralazine, olmesartan, and olmesartan plus MasR antagonist A779 for 2 weeks. Peripheral blood mononuclear cells were isolated and subjected to flow cytometric analysis to determine the number of circulating EPCs. To evaluate the mechanisms of effects of olmesartan on renal degeneration, we investigated morphological changes and expression of ACE1, ACE2, MasR, VEGF, eNOS, NAD(P)H oxidases, HIF-1α, CTGF and TGF-&beta..
