目的
2
研究抗纤灵方(KXL)对5/6肾切除大鼠及爱拉斯汀(Erastin)诱导的人近端肾小管上皮细胞(HK-2)的保护作用。
方法
2
①体内实验:采用SPF级雄性SD大鼠构建5/6肾切除模型,造模成功后将大鼠分为假手术组,模型组,抗纤灵方低、高剂量(KXL-L、KXL-H)组及铁死亡抑制剂Ferrostation-1(Fer-1)组。其中KXL-L、KXL-H组每天分别以10.5 g/kg KXL、21 g/kg KXL灌胃,假手术组和模型组大鼠每天以等体积0.9%氯化钠溶液灌胃,Fer-1组每天以1 mg/kg剂量Fer-1腹腔注射1次,共干预6周。干预结束后,检测大鼠血肌酐(SCr
)、血尿素氮(BUN)水平,收集大鼠24 h尿液检测24 h尿蛋白(24 h-UPro),检测大鼠肾组织亚铁离子(Fe
2+
)水平。HE染色、马松(Masson)染色观察肾组织病变及纤维化程度。免疫荧光检测核转录因子红系2相关因子2(Nrf2)及谷胱甘肽过氧化物酶4(GPX4)蛋白表达。②体外实验:噻唑蓝(MTT)法测细胞活力,选出最佳KXL浓度。HK-2细胞分为正常组、Erastin组、Erastin+KXL组、Erastin+Fer-1组。检测各组谷胱甘肽(GSH)、丙二醛(MDA)、Fe
2+
水平。Western blot法检测各组Ⅰ型胶原蛋白(Col-Ⅰ)、α-平滑肌肌动蛋白(α-SMA)、Nrf2、GPX4蛋白表达。
结果
2
①体内实验:与模型组相比,KXL-L、KXL-H组SCr、BUN、24 h-UPro及Fe
2+
水平降低,Nrf2、GPX4蛋白表达水平升高(
P
<
0.01)。②体外实验:与Erastin组相比,Erastin+KXL组Nrf2、GPX4蛋白表达水平升高,Col-Ⅰ、α-SMA蛋白表达水平降低,MDA、Fe
2+
水平降低,GSH水平升高(
P
<
0.01)。Fer-1的作用效果与KXL一致。
结论
2
KXL减轻肾纤维化,可能与调控Nrf2/GPX4信号通路抑制铁死亡有关。
Objective
2
To investigate the protective effects of Kangxianling Formula (KXL) on 5/6 nephrectomized rats and Erastin-induced human renal tubular epithelial (HK-2) cells.
Methods
2
①
In vivo
experiment: A 5/6 nephrectomy model was established using male SPF-grade SD rats. Successfully modeled rats were randomly assigned into five groups: sham, model, low-dose KXL, high-dose KXL, and Ferrostatin-1 (Fer-1). The KXL low-dose and high-dose groups received 10.5 g/kg or 21 g/kg of KXL via oral gavage, respectively; the sham and model groups received equal volumes of 0.9% sodium chloride solution; the Fer-1 group received 1 mg/kg of Fer-1 via daily intraperitoneal injection. After 6 weeks, serum creatinine (SCr), blood urea nitrogen (BUN), and 24‑hour urinary protein (24 h-UPro) were measured. Ferrous ion (Fe
2+
) levels in renal tissues were assessed. HE and Masson staining were used to observe pathological changes and the degree fibrosis of kidney tissue. Protein expressions of nuclear factor-related factor 2 (Nrf2) and glutathione peroxidase 4 (GPX4) were detected by immunofluorescence. ②
In vitro
experiment: Cell viability was measured by MTT assay to determine the o
ptimal KXL concentration. HK-2 cells were divided into Normal, Erastin, Erastin+KXL, and Erastin+Fer-1 groups. Levels of glutathione (GSH), malondialdehyde (MDA), and Fe
2+
were measured. Protein expressions of collagen Ⅰ (Col-Ⅰ), α-smooth muscle actin (α-SMA), Nrf2, and GPX4 were detected via Western blot.
Results
2
①
In vivo
experiment: Compared with the model group, KXL significantly reduced SCr, BUN, 24 h-UPro, and Fe
2+
levels, while increasing the protein expression of Nrf2 and GPX4 (
P
<
0.01). ②
In vitro
experiment: Compared with the erastin group, the erastin+KXL group exhibited increased Nrf2 and GPX4 expression and decreased Col-Ⅰ and α-SMA expression. Furthermore, KXL treatment reduced MDA and Fe
2+
levels and increased GSH level (
P
<
0.01). The effects of Fer-1 were consistent with those of KXL.
Conclusion
2
KXL alleviates renal fibrosis, potentially by inhibiting ferroptosis through the regulation of the Nrf2/GPX4 signaling pathway.
