Modern pharmacological studies show that Epimedium sagittatum Maxim (EPI) has antioxidant, antiapoptotic, anti-inflammatory effects. However, the effects of EPI on adriamycin-induced nephropathy are unclear.
The main purpose of this study is to investigate the effects of EPI on adriamycin-induced nephropathy in rats.
The chemical composition of EPI was detected by high performance liquid chromatography. Network pharmacology was used to collect the effects of EPI on adriamycin nephropathy; renal histological changes, podocyte injury, inflammatory factors, oxidative stress levels, apoptosis levels, and the PI3K/AKT signaling pathway were examined. Moreover, analyze the effects of icariin (the representative component of EPI) on adriamycin-induced apoptosis and PI3K/AKT signaling pathway of NRK-52e cells.
Network pharmacological results suggested that EPI may ameliorate adriamycin-induced nephropathy by inhibiting inflammatory response and regulating the PI3K/AKT signaling pathway. The experimental results showed that EPI could improve pathological injury, renal function, podocyte injury, and inhibit inflammation, oxidative stress, apoptosis in adriamycin-induced nephropathy rats through the PI3K/AKT signaling pathway. Furthermore, icariin inhibited adriamycin-induced mitochondrial apoptosis in NRK-52e cells.
This study suggested that EPI ameliorates adriamycin-induced nephropathy by reducing inflammation and apoptosis through the PI3K/AKT signaling pathway, icariin may be the pharmacodynamic substance basis for this effect.
现代药理学研究表明,淫羊藿(EPI)具有抗氧化、抗凋亡、抗炎作用。然而,EPI 对阿霉素肾病的作用尚不清楚。
本研究主要目的是探讨 EPI 对阿霉素肾病大鼠的作用。
采用高效液相色谱法检测 EPI 的化学成分。网络药理学收集 EPI 对阿霉素肾病的作用;观察肾脏组织学变化、足细胞损伤、炎症因子、氧化应激水平、细胞凋亡水平及 PI3K/AKT 信号通路。此外,分析淫羊藿苷(EPI 的代表性成分)对阿霉素诱导的 NRK-52e 细胞凋亡及 PI3K/AKT 信号通路的影响。
网络药理学结果表明,EPI 可能通过抑制炎症反应和调节 PI3K/AKT 信号通路改善阿霉素肾病。实验结果表明,EPI 可通过 PI3K/AKT 信号通路改善阿霉素肾病大鼠的病理损伤、肾功能、足细胞损伤,抑制炎症、氧化应激和细胞凋亡。此外,淫羊藿苷抑制阿霉素诱导的 NRK-52e 细胞线粒体凋亡。
本研究表明,EPI 通过减少炎症和凋亡,改善阿霉素肾病,PI3K/AKT 信号通路可能是其作用的药效物质基础,淫羊藿苷可能是其作用的药效物质基础。
