Cisplatin (CP), as a chemotherapeutic drug, causes nephrotoxicity that has limited the clinical utility of CP. Gliclazide (GLZ), as an antihyperglycemic drug, at low dose has antioxidant property. In this study, we aimed to investigate the protective effect of GLZ against CP-induced acute renal injury. Sixty-four BALB/c mice were randomly divided into eight groups. The groups were included as control, GLZ (5, 10, and 25 mg/kg), CP, and GLZ (5, 10, and 25 mg/kg) + CP. Renal function markers (serum creatinine and blood urea nitrogen), oxidative stress markers (malondialdehyde and glutathione), apoptotic marker (caspase-3), and NF-κB were histopathologically evaluated. The results of our study showed that increased urea and creatinine were evidence of CP-induced nephrotoxicity. Histopathological examination revealed tubular epithelial and Bowman degeneration, edema, and cytoplasmic vacuolation in renal tissue structure. Administration of GLZ reduced oxidative stress, caspase-3, and NF-κB activity, and improved kidney function markers in CP-treated mice compared with CP alone group. Also, we observed that the histological tissue structure of the kidney was maintained. GLZ at dose of 25 mg/kg had higher protective effect as compared with other doses. Overall, our study suggests that GLZ with antioxidant, antiapoptotic, and anti-inflammatory properties may be a promising new therapeutic agent to prevent CP-induced nephrotoxicity.

格列齐特通过抑制 NF-κB 和 caspase-3 活性减弱顺铂诱导的肾毒性

顺铂 (CP) 作为一种化疗药物,会导致肾毒性,限制了 CP 的临床应用。格列齐特 (GLZ) 作为一种降糖药,在低剂量时具有抗氧化特性。在本研究中,我们旨在研究 GLZ 对 CP 诱导的急性肾损伤的保护作用。64只BALB/c小鼠随机分为8组。这些组包括作为对照、GLZ(5、10 和 25 毫克/千克)、CP 和 GLZ(5、10 和 25 毫克/千克)+ CP。肾功能标志物(血清肌酐和血尿素氮)、氧化应激标志物(丙二醛和谷胱甘肽)、凋亡标志物(caspase-3)和 NF-κB 进行了组织病理学评估。我们的研究结果表明,尿素和肌酐升高是 CP 诱导的肾毒性的证据。组织病理学检查显示肾组织结构中肾小管上皮和鲍曼变性、水肿和细胞质空泡化。与单独使用 CP 组相比,给予 GLZ 可降低 CP 治疗小鼠的氧化应激、caspase-3 和 NF-κB 活性,并改善肾功能标志物。此外,我们观察到肾脏的组织学组织结构得以维持。与其他剂量相比,25 mg/kg 剂量的 GLZ 具有更高的保护作用。总体而言,我们的研究表明,具有抗氧化、抗细胞凋亡和抗炎特性的 GLZ 可能是预防 CP 诱导的肾毒性的有前途的新治疗剂。与 CP 单独组相比,CP 治疗小鼠的肾功能标志物有所改善。此外,我们观察到肾脏的组织学组织结构得以维持。与其他剂量相比,25 mg/kg 剂量的 GLZ 具有更高的保护作用。总体而言,我们的研究表明,具有抗氧化、抗细胞凋亡和抗炎特性的 GLZ 可能是预防 CP 诱导的肾毒性的有前途的新治疗剂。与 CP 单独组相比,CP 治疗小鼠的肾功能标志物有所改善。此外,我们观察到肾脏的组织学组织结构得以维持。与其他剂量相比,25 mg/kg 剂量的 GLZ 具有更高的保护作用。总体而言,我们的研究表明,具有抗氧化、抗细胞凋亡和抗炎特性的 GLZ 可能是预防 CP 诱导的肾毒性的有前途的新治疗剂。
