摘要:

文题释义:
骨关节炎:由多因素引起关节软骨纤维化、皲裂等的退行性疾病,病理表现为关节软骨变性破坏、软骨下骨硬化或囊变等,可以导致关节疼痛、畸形和活动功能障碍,进而增加心血管事件的发生率及全因死亡率,是目前常见且难治的骨科疾病之一。
黄芪甲苷:是骨科常用中药黄芪的主要有效成分之一。现代药理学研究表明,黄芪甲苷可用于增强机体免疫力、抗病毒、抗应激、抗炎等作用,是一种具有较高研究价值的中药单体。

背景:在骨关节炎的发生、发展过程中,软骨病变是其中的关键环节,探究软骨细胞功能、开发具有软骨细胞保护作用及促软骨细胞分泌Ⅱ型胶原等的药物,是当前探索骨关节炎临床治愈的重要手段。
目的:研究黄芪甲苷对白细胞介素1β诱导的软骨细胞炎性损伤的保护作用,探讨Hippo-YAP通路是否参与到该作用中及其潜在的作用机制。
方法:分离培养SD大鼠乳鼠胫骨与股骨软骨细胞。取对数生长期软骨细胞,分5组:空白组常规培养,模型组加入白细胞介素1β诱导软骨细胞炎性损伤,黄芪甲苷组加入白细胞介素1β+黄芪甲苷,NC-siRNA组转染NC-siRNA+白细胞介素1β+黄芪甲苷,YAP1-siRNA转染组转染YAP1-siRNA+白细胞介素1β+黄芪甲苷。各组细胞培养48 h后,进行相关检测。
结果与结论:①模型组细胞活力低于空白组(P < 0.05),黄芪甲苷组、NC-siRNA组、YAP1-siRNA转染组细胞活力高于模型组(P < 0.05),YAP1-siRNA转染组细胞活力高于NC-siRNA组(P < 0.05);②模型组细胞相凋亡率高于空白组(P < 0.05),黄芪甲苷组、NC-siRNA组、YAP1-siRNA转染组细胞相凋亡率低于模型组(P < 0.05),YAP1-siRNA转染组细胞相凋亡率低于NC-siRNA组(P < 0.05);③RT-qPCR检测显示,模型组金属基质蛋白酶1、组织金属蛋白酶抑制物1 mRNA表达高于空白组(P < 0.05),YAP1、TEAD1 mRNA表达低于空白组(P < 0.05);黄芪甲苷组YAP1 mRNA表达高于模型组(P < 0.05);YAP1-siRNA组金属基质蛋白酶1、组织金属蛋白酶抑制物1 mRNA表达高于NC-siRNA组(P < 0.05),YAP1、TEAD1 mRNA表达低于NC-siRNA组(P < 0.05);④Western Blot检测显示,模型组金属基质蛋白酶1、组织金属蛋白酶抑制物1、YAP1蛋白表达高于空白组(P < 0.05),Ⅱ型胶原、TEAD1、p-YAP1蛋白表达低于空白组(P < 0.05);YAP1-siRNA组金属基质蛋白酶1、织金属蛋白酶抑制物1蛋白表达高于NC-siRNA组(P < 0.05),Ⅱ型胶原、TEAD1、p-YAP1蛋白表达低于NC-siRNA组(P < 0.05);⑤结果表明,黄芪甲苷对白细胞介素1β诱导的软骨细胞炎性损伤存在保护作用,该作用可能与Hippo-YAP通路有关。

Abstract: BACKGROUND: Cartilage lesions are the key to the occurrence and development of osteoarthritis. Exploring the function of chondrocytes and developing drugs for chondrocyte protection and pro-secretion of type II collagen are important means to clinically cure osteoarthritis. 
OBJECTIVE: To explore the protective effect of astragaloside IV (AS-IV) on interleukin-1β-induced inflammation of chondrocytes and to explore whether the Hippo-YAP pathway is involved in this effect and its potential mechanism.  
METHODS: Chondrocytes from the tibia and femur of Sprague-Dawley rats were isolated and cultured. Chondrocytes in the logarithmic growth phase were divided into five groups: blank group in which the cells were routinely cultured, model group in which the cells were treated with interleukin-1β to induce inflammatory injury in chondrocytes, astragaloside IV group in which the cells were treated with interleukin-1β + astragaloside IV, NC-siRNA group in which the cells were transfected with NC-siRNA + interleukin-1β + astragaloside IV, YAP1-siRNA group in which the cells were transfected with YAP1-siRNA+interleukin-1β+astragaloside IV. Relevant measurements were performed after 48 hours of culture.
RESULTS AND CONCLUSION: The cell viability was significantly lower in the model group than the blank group (P < 0.05), significantly higher in the astragaloside IV, NC-siRNA, and YAP1-siRNA groups than the model group (P < 0.05), and significantly higher in the YAP1-siRNA group than the NC-siRNA group (P < 0.05). The apoptotic rate was significantly higher in the model group than the blank group (P < 0.05), significantly lower in the astragaloside IV, NC-siRNA, and YAP1-siRNA transfection groups than the model group (P < 0.05), and significantly lower in the YAP1-siRNA group than the NC-siRNA group (P < 0.05). RT-qRCR results showed that compared with the blank group, the mRNA expressions of metalloproteinase 1 and tissue inhibitor of metalloproteinase 1 were significantly higher in the model group (P < 0.05), while the mRNA expressions of YAP1 and TEAD1 were significantly lower in the model group (P < 0.05). The mRNA expression of YAP1 in the astragaloside IV group was significantly higher than that in the model group (P < 0.05). Compared with the NC-siRNA group, the mRNA expressions of metalloproteinase 1 and tissue inhibitor of metalloproteinase 1 were significantly higher in the YAP1-siRNA group (P < 0.05), while the mRNA expressions of YAP1 and TEAD1 were significantly lower in the YAP1-siRNA group (P < 0.05). Western blot results revealed that compared with the blank group, the protein expressions of metalloproteinase 1, tissue inhibitor of metalloproteinase 1, and YAP1 were significantly higher in the model group (P < 0.05), while the protein expressions of type II collagen, TEAD1, and p-YAP1 were significantly lower in the model group (P < 0.05). Compared with the NC-siRNA group, the protein expressions of metalloproteinase 1 and tissue inhibitor of metalloproteinase 1 were significantly higher in the YAP1-siRNA group (P < 0.05), while the protein expressions of type II collagen, TEAD1, and p-YAP1 were significantly lower in the YAP1-siRNA group (P < 0.05). To conclude, astragaloside IV has a protective effect on interleukin-1β-induced inflammation of chondrocytes, which may be related to the Hippo-YAP pathway.
