摘要:

文题释义:

黄芪甲苷:是中药黄芪中主要的有效活性成分之一,大量研究证实其具有治疗关节炎的作用,对软骨蛋白聚糖合成和软骨细胞增殖具有保护作用。
SDF-1/CXCR4信号通路:基质细胞衍生因子1(SDF-1)是由骨髓基质细胞持续分泌的一种炎性趋化因子,与趋化因子受体4(CXCR4)结合并激活,在多种组织、细胞中广泛表达,对细胞的动员、迁移、增殖和存活起着重要的作用。

背景:骨性关节炎是一种最常见的退行性疾病,但目前仍无延缓或逆转病情的药物,只能消炎镇痛以短期内缓解症状、改善病情。黄芪甲苷是黄芪中一种具有调节免疫、缺血保护、心脏保护、抗炎、抗病毒和抗肿瘤等作用的活性成分。
目的:探讨黄芪甲苷对白细胞介素1β诱导的小鼠骨关节软骨细胞ATDC5损伤的作用及相关机制。
方法:将ATDC5细胞随机分为空白对照组、模型组、单体组、实验组。空白对照组细胞不加任何干预;模型组细胞用100 μg/L白细胞介素1β处理;单体组细胞用5 μg/L黄芪甲苷处理,实验组细胞用100 μg/L白细胞介素1β和5 μg/L黄芪甲苷处理。干预18 h后,采用CCK-8检测细胞增殖活性,Western blot和qRT-PCR检测基质金属蛋白酶3、基质金属蛋白酶9、基质金属蛋白酶13、Ⅱ型胶原、SDF-1、CXCR4的蛋白和mRNA表达变化,甲苯胺蓝染色检测细胞形态改变和细胞数量,锥虫蓝染色检测细胞存活率。

结果与结论:①与空白对照组比较,白细胞介素1β(100 μg/L)明显抑制ATDC5细胞的增殖活性,相关炎症标志物基质金属蛋白酶3、基质金属蛋白酶9、基质金属蛋白酶13的表达升高,Ⅱ型胶原的表达降低,SDF-1、CXCR4的表达升高,SDF-1/CXCR4信号通路激活,诱导细胞出现炎症反应;②与模型组比较,实验组基质金属蛋白酶3、基质金属蛋白酶9、基质金属蛋白酶13的表达降低,Ⅱ型胶原的表达升高,证实黄芪甲苷可以减轻白细胞介素1β诱导的软骨细胞损伤;③此外,与模型组比较,实验组CXCR4、SDF-1的表达降低,证实了黄芪甲苷是通过SDF-1/CXCR4信号通路减轻白细胞介素1β诱导的软骨细胞炎症反应。

Abstract: BACKGROUND: Osteoarthritis is one of the most common degenerative diseases, and there are still no drugs to delay or reverse the disease. Only anti-inflammatory and analgetic treatments can be performed to relieve symptoms and improve patient’s conditions in the short term. Astragaloside IV is an active component of Astragalus membranaceus with immunomodulatory, ischemic protection, cardiac protection, anti-inflammatory, antiviral, and anti-tumor effects.  
OBJECTIVE: To investigate the effects of astragaloside IV on interleukin-1β-induced ATDC5 cell injury and its related mechanism.  
METHODS: ATDC5 cells were randomly divided into blank control group, model group, monomer group, and experimental group. There was no intervention in the blank control group. Cells in the latter three groups were treated with 100 μg/L interleukin-1β, 5 μg/L astragaloside IV, and 100 μg/L interleukin-1β+5 μg/L astragaloside IV, respectively. After 18 hours of treatment, cell counting kit-8 was used to detect cell proliferation. Western blot and qRT-PCR were used to detect the expression of matrix metalloproteinases 3, 9, 13, type II collagen, stromal cell-derived factor 1 (SDF-1), and C-X-C chemokine receptor 4 (CXCR4) at protein and mRNA levels, respectively. Toluidine blue staining was used to detect cell morphological changes and cell numbers, and trypan blue staining was used to detect cell viability.
RESULTS AND CONCLUSION: Interleukin-1β (100 μg/L) significantly inhibited the activity of ATDC5 cells, increased the expression of inflammatory markers (matrix metalloproteinases 3, 9, and 13), decreased the expression of type II collagen, increased the expression of SDF-1 and CXCR4, activated the SDF-1/CXCR4 pathway, and induced inflammatory responses in cells. Compared with the model group, astragaloside IV significantly reduced the expression of matrix metalloproteinases 3, 9, and 13, and increased the expression of type II collagen, indicating that astragaloside IV can alleviate chondrocyte injury induced by interleukin-1β. In addition, the expression of CXCR4 and SDF-1 was decreased in the experimental group compared with the model group, indicating that astragaloside IV alleviates interleukin-1β-induced chondrocyte inflammation through the SDF-1/CXCR4 signaling pathway.  

Key words: osteoarthritis, astragaloside IV, SDF-1/CXCR4 signaling pathway, ATDC5 cell, inflammatory response
