hyperoside and Acute-Kidney-Injury

Cisplatin is a widely used chemotherapeutic agent to treat solid tumours in clinics. However, cisplatin-induced acute kidney injury (AKI) limits its clinical application. This study investigated the effect of hyperoside (a flavonol glycoside compound) on regulating AKI.The model of cisplatin-induced AKI was established, and hyperoside was preadministered to investigate its effect on improving kidney injury.Hyperoside ameliorated renal pathological damage, reduced the accumulation of SCr, BUN, Kim-1 and indoxyl sulphate

Hyperin, a flavonoid compound found in Ericaceae, Guttiferae, and Celastraceae, has been reported to have anti-inflammatory effects. In the present study, we investigated the effects of hyperin on cisplatin-induced acute kidney injury (AKI) in mice. The renal tissue damage induced by cisplatin was detected by H&E staining. Blood urea nitrogen (BUN), creatinine, reactive oxygen species (ROS), and malondialdehyde (MDA) were also detected. Further, the effects of hyperin on cisplatin-induced TNF-α, IL-1β and IL-6 were detected by ELISA. In addition, the phosphorylation of nuclear factor kappa B (NF-κB) and the expression of nuclear factor E2-related factor-2 (Nrf2) and HO-1 were detected by western blot analysis. The results showed that hyperin attenuated histological changes of kidney induced by cisplatin. The levels of BUN, creatinine, ROS, MDA, TNF-α, IL-1β and IL-6 induced by cisplatin were also inhibited by hyperin. Cisplatin-induced NF-κB activation was inhibited by hyperin. Additionally, hyperin was found to up regulate the expression of Nrf2 and HO-1. In conclusion, the results suggest that hyperin protects against cisplatin-induced AKI by inhibiting inflammatory and oxidant response.

Hyperin is a flavonoid compound derived from Ericaceae, Guttifera, and Celastraceae that has been shown to have various biological effects, such as anti-inflammatory and anti-oxidant effects. However, there is no evidence to show the protective effects of hyperin on lipopolysaccharide (LPS)-induced acute kidney injury (AKI). Therefore, we investigated the protective effects and mechanism of hyperin on LPS-induced AKI in mice. The levels of TNF-α, IL-6, and IL-1β were tested by ELISA. The effects of hyperin on blood urea nitrogen (BUN) and serum creatinine were also detected. In addition, the expression of TLR4, NF-κB, and NLRP3 were detected by western blot analysis. The results showed that hyperin significantly inhibited LPS-induced TNF-α, IL-6, and IL-1β production. The levels of BUN and creatinine were also suppressed by hyperin. Furthermore, LPS-induced TLR4 expression and NF-κB activation were also inhibited by hyperin. In addition, treatment of hyperin dose-dependently inhibited LPS-induced NLRP3 signaling pathway. In conclusion, the results showed that hyperin inhibited LPS-induced inflammatory response by inhibiting TLR4 and NLRP3 signaling pathways. Hyperin has potential application prospects in the treatment of sepsis-induced AKI.
