摘要:

文题释义:

铁死亡:是一种铁依赖性的细胞程序性死亡,由Dixon等人在2012年首次提出,该种新型的细胞死亡形式与铁代谢异常及脂质过氧化等密切相关,其作用分子、效应形态及生化特征等方面与凋亡、自噬、坏死、焦亡等其他细胞死亡方式有所不同。
毛蕊花糖苷:又称类叶升麻苷,是一种易溶于水、颜色呈类白色或淡黄色的苯乙醇苷类化合物,在自然界中分布广泛,可以从地黄、肉苁蓉、前子、桂花、裸花等植物中分离提纯得到毛蕊花糖苷单体。目前研究发现毛蕊花糖苷具有抗炎、抗氧化、抗肿瘤、保护神经等作用,是非常具有研究价值的天然植物资源。


背景:近年越来越多的研究证实多巴胺能神经元细胞铁死亡参与了帕金森病的发病,毛蕊花糖苷目前被证实具有抗氧化、抗炎和神经保护作用。
目的:探讨毛蕊花糖苷对Erastin诱导的MN9D细胞铁死亡的保护效果及作用机制。
方法:以MN9D细胞为研究对象,分为对照组、模型组(20 μmol/L Erastin组)、Erastin+1 μg/mL毛蕊花糖苷组、Erastin+5 μg/mL毛蕊花糖苷组、Erastin+10 μg/mL毛蕊花糖苷组。MN9D细胞在CO2恒温培养箱中培养24 h,然后用不同质量浓度毛蕊花糖苷预处理8 h,再加入20 μmol/L Erastin诱导24 h后,采用ELISA法检测还原型谷胱甘肽、超氧化物歧化酶、总铁离子、丙二醛水平,免疫组织化学法检测酪氨酸羟化酶的表达,Western blot法检测酪氨酸羟化酶、核因子红细胞-2相关因子2、血红素加氧酶1、谷胱甘肽过氧化物酶4蛋白表达。
结果与结论:①与对照组相比,模型组还原型谷胱甘肽、超氧化物歧化酶水平明显减少(P < 0.05),丙二醛和总铁离子水平明显增加(P < 0.05);与模型组相比,毛蕊花糖苷1,5,10 μg/mL组还原型谷胱甘肽、超氧化物歧化酶水平明显增加(P < 0.05),丙二醛和总铁离子水平明减少(P < 0.05);②与对照组相比,模型组酪氨酸羟化酶阳性细胞面积明显减少(P < 0.05);与模型组相比,毛蕊花糖苷1,5,10 μg/mL组酪氨酸羟化酶阳性细胞面积明显增加(P < 0.05);③与对照组相比,模型组酪氨酸羟化酶、核因子红细胞-2相关因子2、血红素加氧酶1、谷胱甘肽过氧化物酶4的蛋白表达明显减少(P < 0.05);与模型组相比,毛蕊花糖苷1,5,10 μg/mL组酪氨酸羟化酶、核因子红细胞-2相关因子2、血红素加氧酶1、谷胱甘肽过氧化物酶4的蛋白表达明显增加(P < 0.05)。结果提示:毛蕊花糖苷对Erastin诱导的MN9D细胞铁死亡具有明显的抑制作用,其机制可能通过作用于核因子红细胞-2相关因子2/血红素加氧酶1/谷胱甘肽过氧化物酶4通路实现的。

Abstract: BACKGROUND: In recent years, more and more studies have confirmed that ferroptosis of dopaminergic neurons is involved in the pathogenesis of Parkinson’s disease, and verbascoside has been confirmed to have antioxidant, anti-inflammatory and neuroprotective effects.
OBJECTIVE: To investigate the protective effect of verbascoside on Erastin-induced ferroptosis of MN9D cells and its action mechanism.
METHODS: MN9D cells were divided into control group, model group (20 μmol/L Erastin group), Erastin+1 μg/mL verbascoside group, Erastin+5 μg/mL verbascoside group, and Erastin+10 μg/mL verbascoside group. MN9D cells were cultured in a CO2 incubator for 24 hours, then pretreated with different mass concentrations of verbascoside for 8 hours, and induced with 20 μmol/L Erastin for 24 hours. The levels of reduced glutathione, superoxide dismutase, total iron ion, and malondialdehyde were detected by ELISA. The expression of tyrosine hydroxylase was detected by immunohistochemistry. The expressions of tyrosine hydroxylase, nuclear factor erythrocyte-2-associated factor 2, heme oxygenase-1, and glutathione peroxidase 4 were detected by western blot assay. 
RESULTS AND CONCLUSION: (1) Compared with the control group, the levels of reduced glutathione and superoxide dismutase were significantly decreased (P < 0.05), and the levels of malondialdehyde and total iron ion were significantly increased in the model group (P < 0.05). Compared with the model group, the levels of reduced glutathione and superoxide dismutase were significantly increased (P < 0.05), and the levels of malondialdehyde and total iron ionized water were decreased in 1, 5, 10 μg/mL verbascoside groups (P < 0.05). (2) Compared with the control group, the area of tyrosine hydroxylase positive cells in the model group was significantly reduced (P < 0.05). Compared with the model group, the area of tyrosine hydroxylase positive cells was significantly increased in 1, 5, 10 μg/mL verbascoside groups (P < 0.05). (3) Compared with the control group, the protein expressions of tyrosine hydroxylase, nuclear factor erythrocyte-2-associated factor 2, heme oxygenase-1 and glutathione peroxidase 4 were significantly decreased in the model group (P < 0.05). Compared with the model group, the protein expression levels of tyrosine hydroxylase, nuclear factor erythrocyte-2-associated factor 2, heme oxygenase-1, and glutathione peroxidase 4 were significantly increased in 1, 5, 10 μg/mL verbascoside groups (P < 0.05). The results suggested that verbascoside could inhibit Erastin-induced ferroptosis in MN9D cells, possibly by activating nuclear factor erythrocyte-2-associated factor 2/ heme oxygenase-1/glutathione peroxidase 4 pathway.

Key words: verbascoside, Erastin, MN9D cell, ferroptosis, nuclear factor erythrocyte-2-associated factor 2, heme oxygenase-1, glutathione peroxidase 4
