摘要: 背景 顺铂诱导的药物性肝损伤是肿瘤化疗常见的不良反应,严重影响了患者临床治疗。氢作为一种选择性抗氧化剂,在多种损伤相关的疾病中均具有良好的辅助治疗作用,但其在顺铂诱导的肝损伤中的预防作用及其机制尚未明确。目的 探讨氢水对顺铂致肝细胞氧化应激性损伤的保护作用及作用机制。方法 于 2022 年 6 月—2023 年 6 月取人正常肝细胞株 WRL68 分为对照组、顺铂组、氢水组、氢水 + 顺铂组。对照组采用含 10% 胎牛血清的 RPMI-1640 培养基培养 48 h;顺铂组采用含 10% 胎牛血清的 RPMI-1640 培养基培养 24 h 后,加入 3 μg/mL 顺铂继续培养 24 h;氢水组采用 0.6 mg/L 氢水培养基培养 48 h;氢水 + 顺铂组采用 0.6 mg/L 氢水培养基培养 24 h 后,加入3 μg/mL 顺铂继续培养 24 h。收集各组细胞,采用 CCK-8 法检测细胞活力,流式细胞仪检测细胞凋亡率,罗丹明 123荧光探针染色法检测粒体膜电位(MMP),DCFH-DA 荧光探针染色法检测细胞内活性氧(ROS),Western blot 和RT-qPCR 检测细胞内核因子红细胞 2 相关因子 2(NFE2L2)、血红素加氧酶 1(HMOX1)蛋白及 mRNA 表达水平。结果 与对照组相比,顺铂组 WRL68 细胞凋亡率、ROS 水平升高(P0.05);氢水组 MMP 水平及 NFE2L2、HMOX1 的蛋白及 mRNA 水平均高于对照组(P<0.05)。与顺铂组相比,氢水 + 顺铂组WRL68细胞凋亡率、ROS水平均降低(P<0.05),MMP水平及NFE2L2、HMOX1的蛋白及 mRNA表达水平均升高(P<0.05)。结论 氢水可通过激活NFE2L2/HMOX1信号通路,提高线粒体膜电位,抑制顺铂引起的肝细胞氧化应激性损伤,从而减轻药物性肝损伤。

Abstract: Background Cisplatin induced drug-induced liver injury is a common adverse reaction in tumor chemotherapy,which seriously disturbs the clinical treatment of patients. Hydrogen,as a selective antioxidant,has good adjunctive therapeutic effects in various injury related diseases,but its preventive effect and mechanism in cisplatin induced liver injury are not clear. Objective To study the protective effect and mechanism of hydrogen water on oxidative stress injury of hepatocytes induced by cisplatin. Methods From June 2022 to June 2023,human normal liver cell line WRL68 were divided into control group,cisplatin group,hydrogen water group,and hydrogen water plus cisplatin group. Control group was cultured with RPMI-1640 medium containing 10% fetal bovine serum for 48 h. Cisplatin group was cultured with RPMI-1640 medium containing 10% fetal bovine serum for 24 h,then added 3 μg/mL cisplatin and continued culturing for 24 h. Hydrogen water group was cultured with 0.6 mg/L hydrogen water medium for 48 h. Hydrogen water+cisplatin group was cultured with 0.6 mg/ L hydrogen water medium for 24h,then added 3 μg/mL cisplatin and continued culturing for 24 h. Then collect cells of each gorup,and hepatocyte activity was detected with CCK-8 method. Cell apoptosis was detected by flow cytometry. Mitochondrial membrane potential(MMP)was detected via Rhodamine 123 fluorescence staining method,and intracellular reactive oxygen species(ROS)levels were detected via DCFH-DA fluorescence probe staining method,the proteins and mRNA expression of nuclear factor erythroid 2-related factor 2(NFE2L2) and heme oxygenase-1(HMOX1) were detected by western blot and RT-qPCR. Results Compared with the control group,the apoptosis rate and ROS level of cisplatin group increased(P<0.05),while the relative levels of MMP,NFE2L2,HMOX1 protein and mRNA decreased(P<0.05). There was no statistically significant difference in cell apoptosis rate and ROS level between hydrogen water group and control group(P>0.05),while the relative levels of MMP,NFE2L2,and HMOX1 proteins and mRNA increased(P<0.05). Compared with cisplatin group,hydrogen water plus cisplatin group decreased in cell apoptosis rate and ROS level(P<0.05),while the relative levels of MMP,NFE2L2,HMOX1 proteins and mRNA increased(P<0.05). Conclusion Hydrogen water can inhibit the oxidative stress injury in cisplatin induced hepatocytes via activating NFE2L2/HMOX1 signaling pathway,and improving mitochondrial membrane potential,then alleviate drug-induced liver injury.
