Canagliflozin is a sodium glucose co-transporter 2 (SGLT2) inhibitor that is currently available for the management of type 2 diabetes mellitus. The present study investigated the effect of canagliflozin on cisplatin (CP)-induced nephrotoxicity in mice. The animals were divided into four groups (n = 6). The first and second groups received normal saline (control) and intraperitoneal (i.p.) cisplatin (20 mg/kg) on day 7, respectively. The third and fourth groups were given a single intraperitoneal (i.p.) injection of CP (20 mg/kg) on day 7 and canagliflozin (10 mg/kg/day) and (30 mg/kg/day), for 10 days, respectively. At day 11, animals were anesthetized and blood collected and kidneys were removed. CP significantly increased the plasma urea, creatinine, cystatin C, and clusterin concentrations and neutrophil gelatinase-associated lipocalin (NGAL) activity. In addition, CP increased urinary albumin/creatinine ratio, N-acetyl-β-D-glucosaminidase (NAG) activity, and liver-type fatty acid-binding protein (L-FABP) concentrations and reduced creatinine clearance. CP also significantly increased the plasma concentration of inflammatory cytokines [plasma tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and interleukin-1beta (IL-1β)] and significantly reduced antioxidant indices [catalase, glutathione reductase (GR), and superoxide dismutase (SOD)]. Histopathologically, CP caused a remarkable renal damage compared with control. Canagliflozin significantly ameliorated CP-induced biochemical and histopathological changes. The protective effect of canagliflozin is most likely due to anti-inflammatory and antioxidant effects. Our results show that administration of canagliflozin reversed the biochemical and histopathological indices of CP-induced nephrotoxicity in mice.
卡格列净是一种钠-葡萄糖协同转运蛋白 2(SGLT2)抑制剂,目前可用于治疗 2 型糖尿病。本研究探讨了卡格列净对顺铂(CP)诱导的小鼠肾毒性的影响。动物分为四组(n=6)。第一组和第二组分别在第 7 天接受生理盐水(对照)和腹腔注射(i.p.)顺铂(20mg/kg)。第三组和第四组分别在第 7 天单次腹腔注射 CP(20mg/kg)和卡格列净(10mg/kg/天)和(30mg/kg/天),连续 10 天。第 11 天,动物麻醉后采血,取出肾脏。CP 显著增加了血浆尿素、肌酐、胱抑素 C 和簇集素浓度以及中性粒细胞明胶酶相关脂质运载蛋白(NGAL)活性。此外,CP 增加了尿白蛋白/肌酐比值、N-乙酰-β-D-氨基葡萄糖苷酶(NAG)活性和肝型脂肪酸结合蛋白(L-FABP)浓度,降低了肌酐清除率。CP 还显著增加了血浆中炎症细胞因子[肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)和白细胞介素-1β(IL-1β)]的浓度,显著降低了抗氧化指标[过氧化氢酶、谷胱甘肽还原酶(GR)和超氧化物歧化酶(SOD)]。组织病理学检查显示,CP 引起的肾损伤明显大于对照组。卡格列净显著改善 CP 诱导的生化和组织病理学变化。卡格列净的保护作用可能与其抗炎和抗氧化作用有关。我们的结果表明,卡格列净可逆转 CP 诱导的小鼠肾毒性的生化和组织病理学指标。
