Ischemia and reperfusion injury (I/R) is a serious condition leading to organ failure, characterized by poor blood supply followed by rapid resuscitation of blood flow and reoxygenation. Renal failure caused by renal ischemia has high mortality and morbidity. This study aimed to explore the potential role of Semaglutide as a novel and effective therapeutic strategy for acute renal failure. Additionally, we aimed to assess the possible protective effect of Semaglutide on kidney I/R injury in mice through modulation of the inflammatory and oxidative pathways via phosphatidylinositol 3-kinase/adenosine triphosphate (PI3K/AKT) activation. We employed twenty-eight albino mice to induce the I/R injury model by clamping the renal artery for 30 min followed by a period of reperfusion for 2 hours. The control group was exposed to I/R injury, while the Semaglutide-treated group was pretreated with the drug 12 hours before induction of ischemia at a dose of 100 nmol/L/kg via the intraperitoneal route (i.p). In addition, the DMSO-treated group was subjected to similar conditions to the Semaglutide-treated group. At the end of the experiments, kidneys and blood samples were collected for investigation. Semaglutide could act as a protective agent against acute kidney injury by reducing inflammatory molecules such as tumor necrosis factor-alpha (TNF-α) and its cognate receptor, TNF-α R, interleukine-6 (IL-6). Furthermore, Semaglutide reduced F8 isoprostane levels, increased PI3K and AKT levels in renal tissues, and mitigated renal damage. Semaglutide had renoprotective effects via modulation of the inflammatory response and oxidative pathway by targeting the PI3K/AKT signaling pathway.
缺血再灌注损伤(I/R)是一种导致器官衰竭的严重情况,其特征是血液供应不良,随后迅速恢复血流和再氧合。肾缺血引起的肾衰竭死亡率和发病率都很高。本研究旨在探讨Semaglutide 作为一种治疗急性肾衰竭的新的有效治疗策略的潜在作用。此外,我们旨在通过激活磷脂酰肌醇 3-激酶/三磷酸腺苷(PI3K/AKT)来评估 Semaglutide 对小鼠肾 I/R 损伤的可能保护作用,从而调节炎症和氧化途径。我们使用 28 只白化小鼠通过夹闭肾动脉 30 分钟,然后再灌注 2 小时来诱导 I/R 损伤模型。对照组暴露于 I/R 损伤,而 Semaglutide 治疗组在缺血诱导前 12 小时以 100nmol/L/kg 的剂量通过腹腔途径(i.p)预先用药物治疗(n=8)。此外,DMSO 处理组接受与 Semaglutide 处理组相似的条件。实验结束时,收集肾脏和血液样本进行研究。Semaglutide 通过减少肿瘤坏死因子-α(TNF-α)及其同源受体 TNF-α R、白细胞介素-6(IL-6)等炎症分子,可作为急性肾损伤的保护剂。此外,Semaglutide 降低了 F8 异前列腺素水平,增加了肾脏组织中的 PI3K 和 AKT 水平,并减轻了肾损伤。Semaglutide 通过靶向 PI3K/AKT 信号通路调节炎症反应和氧化途径,发挥肾脏保护作用。
