Its use should be limited due to side effects such as nephrotoxicity, myelotoxicity, and hepatotoxicity. Nebivolol (NBV), which is a beta-blocker used in the treatment of hypertension, also contributes to vasodilation in tissues by activating the endothelial nitric oxide synthase (eNOS) enzyme. The purpose of this study is to research the effect of NBV on MTX-induced nephrotoxicity through the AKT1\/hypoxia-inducible factor 1-alpha (Hif-1\u03b1)\/eNOS signaling pathway. The rats were randomly divided into three groups of eight each. The groups were control, MTX, and MTX + NBV. A single dose of 20\u2009mg\/kg MTX was given intraperitoneally to the rats on the first day of the study and 10\u2009mg\/kg NBV was given orally to the treatment group for 7\u2009days. At the end of the study, rats' blood and kidney tissues were taken for histopathological, immunohistochemical, and biochemical examinations. MTX administration significantly decreased the expression levels of AKT1, eNOS, and Hif-1\u03b1\u00a0compared with the control group ( p\u00a0&lt;\u00a00.001 for all), and NBV treatment increased these values compared with the MTX group ( p\u00a0&lt;\u00a00.001 for all). In conclusion, NBV treatment ameliorated the MTX-induced nephrotoxicity via AKT1\/Hif-1\u03b1\/eNOS signaling pathway.
