目的 探讨蝙蝠葛碱(Dau)能否用于缓解肾脏缺血再灌注(IR)诱导的急性肾损伤。 方法 C57BL6小鼠分为Sham组、IRI组、IRI + Dau组,每组12只。小鼠首先Dau灌胃(15 mg/kg),再经过肾脏缺血再灌注24 h后,取血和肾脏组织,通过HE染色检查肾脏组织病理损伤;检测肾功能指标血清肌酐和尿素氮;通过蛋白质免疫印迹和免疫荧光检测脂质过氧化相关蛋白质表达;通过qPCR检测炎症因子表达;通过免疫荧光检测核转录因子κB(NF-κB)核转位情况组间比较采用t检验。 结果 相较于Sham组,IRI + Dau组可以明显缓解IR诱导的急性肾损伤,IRI + Dau组小鼠的血清肌酐(P < 0.001)和尿素氮(P < 0.000 1)较于IRI组小鼠显著降低,Dau可以明显减轻IR诱导的肾脏组织产生的脂质过氧化物(P < 0.001),而不影响Gpx4(P = 0.919)和Acsl4(P = 0.086)脂质过氧化相关蛋白的表达;Dau抑制IR诱导的肾脏NF-κB核移位(P < 0.001),并缓解肾脏细胞凋亡水平(P = 0.004)。 结论 Dau通过抑制IR诱导的肾脏脂质过氧化物累积和肾脏NF-κB核移位,缓解肾脏组织炎症因子释放和组织细胞凋亡,进而减轻IR诱导的肾脏组织损伤。

Objective To investigate whether Dauricine (Dau) can ameliorate acute kidney injury induced by renal ischemia-reperfusion (IR) in mice. Methods C57BL/6 mice were randomly assigned to three experimental groups: sham operation, ischemia-reperfusion injury (IRI), and IRI treated with daunorubicin (IRI+Dau), with 12 animals in each group. Following oral administration of Dau (15 mg/kg), renal ischemia-reperfusion was induced, and blood and kidney tissue samples were collected 24 hours post-surgery. Histopathological changes were assessed using hematoxylin and eosin (HE) staining. Renal function was evaluated by measuring serum creatinine and blood urea nitrogen (BUN) levels. Protein expression related to lipid peroxidation was analyzed using western blotting and immunofluorescence. Inflammatory gene expression was determined via quantitative polymerase chain reaction (qPCR). Nuclear translocation of nuclear factor κB (NF-κB), a key inflammatory marker, was assessed using immu-nofluorescence. Statistical comparisons between groups were performed using t-tests. Results The administration of Dau significantly ameliorated IR-induced acute kidney injury compared to the Sham group. Serum creatinine (P < 0.001) and urea nitrogen (P < 0.000 1) levels were markedly decreased in Dau-treated mice relative to those in the IRI group. Furthermore, Dau significantly suppressed lipid peroxide production in renal tissues (P < 0.001), without significantly affecting the expression levels of Gpx4 (P = 0.919) and Acsl4 (P = 0.086), two key proteins involved in lipid peroxidation. In addition, Dau effectively inhibited IR-induced nuclear translocation of NF-κB (P < 0.001) and reduced apoptosis in kidney cells (P = 0.004). Conclusion Dau mitigates IR-induced kidney damage by reducing the accumulation of lipid peroxides and inhibiting the nuclear translocation of NF-κB, thereby attenuating inflammation and renal cell apoptosis.
