Acute renal failure is a common clinical disease in canines, affecting antioxidant levels and decreasing the body's resistance. This study aims to explore the therapeutic mechanism of Nano-selenium in acute renal failure. The histopathological and imaging changes of kidney tissue were observed with the gene and protein expression levels of Keap1, Nrf2, HO-1, and NQO1 in the kidney. According to our findings, adding nano-selenium can effectively reduce the concentration of CRE and BUN in blood and kidney tissues. It increased the activity of GSH-PX and SOD by an effective reduction of MDA. Through pathological and imaging observations, it was found that adding nano-selenium could improve the kidney tissue structure of acute renal failure. The results of the RT-qPCR experiment showed that after the addition of nano-selenium, the mRNA expression of the Keap1 gene decreased significantly. In contrast, the mRNA expression of the Nrf2, HO-1, and NQO1 genes increased significantly. The experimental results were further verified by western blot and immunohistochemical analysis. Hence, the nano-selenium intervention improved kidney function and increased antioxidant levels in canines suffering from acute renal failure with the involvement of the Keap1-Nrf2/ARE signaling pathway.
