摘要:


文题释义:

芒柄花素:是一种天然异黄酮化合物,广泛富含于红车轴草、黄芪、甘草等药用植物中,具有抗炎、抗氧化和免疫调节等特性,在高脂血症、糖尿病、肿瘤和心血管疾病中发挥着重要作用。
氧化应激:是有害刺激物引起细胞、组织、器官的氧化和抗氧化机制失衡,是参与肝星状细胞活化和肝脏疾病发展的关键因素。

背景:研究发现,芒柄花素具有抗氧化、抗炎和免疫调节等生物活性。然而,芒柄花素是否具有调节葡萄糖氧化酶诱导大鼠肝星状细胞氧化应激的作用尚不明确。
目的:探究芒柄花素对葡萄糖氧化酶诱导大鼠肝星状细胞HSC-T6氧化应激的作用及可能的机制。
方法:实验分为对照组,模型组,芒柄花素低、中、高剂量组和姜黄素组。对照组不做任何处理,模型组用葡萄糖氧化酶处理2 h,芒柄花素组和姜黄素组先用不同浓度的芒柄花素或姜黄素处理HSC-T6细胞24 h,再用葡萄糖氧化酶处理2 h。采用CCK8法检测芒柄花素对HSC-T6细胞活力的影响;化学试剂盒检测各组细胞中超氧化物歧化酶和丙二醛水平;DCFH-DA荧光探针检测各组细胞中活性氧表达;ELISA检测各组细胞培养上清液中白细胞介素1β和肿瘤坏死因子α水平;免疫细胞荧光染色观察各组细胞中Ⅰ型胶原表达;Western blot检测各组细胞中Ⅰ型胶原、NOX4和Nrf2蛋白表达。

结果与结论:①与模型组比较,芒柄花素能抑制HSC-T6细胞的活化增殖(P < 0.05);②与对照组比较,模型组HSC-T6细胞中超氧化物歧化酶活性和Nrf2蛋白表达均明显减低(P < 0.05),而丙二醛、活性氧、白细胞介素1β、肿瘤坏死因子α、Ⅰ型胶原和NOX4蛋白表达明显增加(P < 0.05);③与模型组比较,芒柄花素处理组和姜黄素组HSC-T6细胞中超氧化物歧化酶活性和Nrf2蛋白表达均明显增加(P < 0.05),而丙二醛、活性氧、白细胞介素1β、肿瘤坏死因子 α、Ⅰ型胶原和NOX4蛋白表达明显降低(P < 0.05);④结果表明芒柄花素能通过Nrf2/NOX4信号通路抑制葡萄糖氧化酶诱导的肝星状细胞活化增殖。

Abstract: BACKGROUND: Studies have shown that formononetin possesses potent anti-inflammatory, oxidative stress and immunomodulatory properties. However, it is still unclear whether formononetin can regulate the oxidative stress induced by glucose oxidase in rat hepatic stellate cells.
OBJECTIVE: To investigate the possible mechanism and the effect of formononetin on oxidative stress in rat hepatic stellate cells HSC-T6 induced by glucose oxidase. 
METHODS: The experiment contained control group, model group, low-, medium- and high-dose formononetin groups and curcumin group. The control group was not subjected to any treatment; the model group was treated with glucose oxidase for 2 hours; the formononetin and curcumin groups were treated with different concentrations of formononetin or curcumin for 24 hours, followed by glucose oxidase for 2 hours. CCK8 assay was used to investigate the effect of formononetin on HSC-T6 cell viability. Chemical kits were used to measure the contents of superoxide dismutase and malondialdehyde in each group. DCFH-DA fluorescence staining was performed to determine reactive oxygen species expression in each group. ELISA was performed to measure interleukin 1β and tumor necrosis factor α in each group. Immunofluorescence staining was used to detect the expression of type I collagen in each group. Western blot assay was used to measure the protein level of type I collagen, NOX4 and Nrf2 in each group.   
RESULTS AND CONCLUSION: (1) Compared with the model group, formononetin could inhibit the activation and proliferation of HSC-T6 cells (P < 0.05). (2) Compared with the control group, superoxide dismutase activity and Nrf2 protein expression of HSC-T6 cells in the model group were significantly down-regulated (P < 0.05), while malondialdehyde, reactive oxygen species, interleukin 1β, tumor necrosis factor α, type I collagen and NOX4 protein expression levels were significantly up-regulated (P < 0.05). (3) Compared with the model group, superoxide dismutase activity and Nrf2 protein expression of HSC-T6 cells in formononetin treatment groups and curcumin group were significantly increased (P < 0.05), while malondialdehyde, reactive oxygen species, interleukin 1β, tumor necrosis factor α, type I collagen and NOX4 protein expression levels were markedly decreased (P < 0.05). (4) The results suggested that formononetin could inhibit glucose oxidase-induced activation and proliferation of hepatic stellate cells by regulating the Nrf2/NOX4 signaling pathway.
