摘要:


文题释义:
黄芪甲苷:是中药黄芪的主要活性成分之一,具有增强机体免疫功能、强心降压、降血糖、利尿、抗衰老、抗疲劳等作用。
细胞外信号调节激酶/腺苷酸激活蛋白激酶信号通路:细胞外信号调节激酶作为丝裂原活化蛋白激酶通路家族的一员,在细胞增殖、分化等方面发挥重要作用。腺苷酸激活蛋白激酶是生物能量代谢调节的关键分子,是研究糖尿病及其他代谢相关疾病的核心,它表达于各种代谢相关的器官中,能被机体各种刺激激活,包括细胞压力、运动和很多激素及能影响细胞代谢的物质。

背景:氧化应激是导致骨质疏松症的主要原因之一,减少氧化应激水平与增加抗氧化防御是治疗骨质疏松症的重要研究方向。研究证实黄芪甲苷具有抗骨质疏松作用,但其作用机制尚不明确。
目的:探讨黄芪甲苷对氧化应激条件下MC3T3-E1细胞成骨的作用。
方法:将MC3T3-E1细胞分4组培养:对照组加入完全培养基,模型组加入含过氧化氢的完全培养基干预24 h后更换为完全培养基,黄芪甲苷组加入含过氧化氢、黄芪甲苷的完全培养基干预24 h后更换为含黄芪甲苷的完全培养基,抑制剂组加入含过氧化氢、黄芪甲苷、细胞外信号调节激酶(extracellular signal-regulated kinases,ERK)抑制剂的完全培养基干预24 h后更换为含黄芪甲苷、ERK抑制剂的完全培养基。过氧化氢干预48 h后,通过丙二醛含量检测黄芪甲苷对MC3T3-E1细胞氧化应激的缓解作用;过氧化氢干预48 h后进行成骨诱导培养,通过碱性磷酸酶染色、茜素红染色验证MC3T3-E1细胞成骨及矿化能力,通过RT-qPCR检测成骨相关基因的表达,Western blot检测成骨相关蛋白及ERK/腺苷酸激活蛋白激酶(AMP-activated protein kinase,AMPK)信号通路蛋白的表达。
结果与结论:①模型组细胞内碱性磷酸酶含量与矿化结节形成均少于对照组(P < 0.05),黄芪甲苷组细胞内碱性磷酸酶含量与矿化结节形成均多于模型组(P < 0.05)。②与对照组比较,模型组细胞内丙二醛含量增加(P < 0.05),骨钙素、RUNX2、Ⅰ型胶原蛋白的mRNA与蛋白表达均降低(P < 0.05),AMPK mRNA与p-AMPK蛋白表达升高(P < 0.05);与模型组比较,黄芪甲苷组细胞内丙二醛含量减少(P < 0.05),骨钙素、RUNX2、Ⅰ型胶原蛋白的mRNA与蛋白表达均升高(P < 0.05),ERK1/2、AMPK mRNA表达升高(P < 0.05),p-AMPK、p-ERK1/2蛋白表达均升高(P < 0.05);ERK抑制剂可部分抑制黄芪甲苷的上述作用。③结果表明,黄芪甲苷可通过激活ERK/AMPK信号通路促进氧化应激条件下MC3T3-E1细胞的成骨分化。

Abstract: BACKGROUND: Oxidative stress is one of the main causes of osteoporosis, and reducing the level of oxidative stress with increasing antioxidant defense is an important research direction for the treatment of osteoporosis. Studies have confirmed that astragaloside IV has anti-osteoporosis effects, but its mechanism of action is not clear.
OBJECTIVE: To investigate the osteogenic effect of astragaloside IV in MC3T3-E1 cells under oxidative stress conditions. 
METHODS: MC3T3-E1 cells were randomly divided into four groups: the control group was cultured in a complete medium; the model group was cultured in the complete medium containing hydrogen peroxide which was replaced with another complete medium after 24 hours of intervention; the astragaloside IV group was cultured with the complete medium containing hydrogen peroxide and astragaloside IV which was replaced with another complete medium containing astragaloside IV after 24 hours of intervention; and the inhibitor group was cultured in the complete medium containing hydrogen peroxide, astragaloside IV, and extracellular signal-regulated kinases (ERK) inhibitor which was replaced with complete medium containing hydrogen peroxide, astragaloside IV, and ERK inhibitor after 24 hours of intervention. After 48 hours of intervention with hydrogen peroxide, malondialdehyde content was detected to evaluate the mitigating effect of astragaloside IV on the oxidative stress in MC3T3-E1 cells. Osteogenic induction was performed after 48 hours of intervention with hydrogen peroxide, and the osteogenic and mineralizing ability of MC3T3-E1 cells was verified by alkaline phosphatase staining and alizarin red staining; the expression of osteogenesis-related genes was detected by RT-qPCR; and the expression of osteogenesis-related proteins and ERK/AMP-activated protein kinase (AMPK) signaling pathway proteins was detected by western blot. 
RESULTS AND CONCLUSION: The intracellular alkaline phosphatase content and mineralized nodule formation were less in the model group than in the control group (P < 0.05), and were more in the astragaloside IV group than in the model group (P < 0.05). Compared with the control group, intracellular malondialdehyde content increased in the model group (P < 0.05), mRNA and protein expression of osteocalcin, RUNX2, and type I collagen decreased (P < 0.05), and AMPK mRNA and p-AMPK protein expressions were elevated (P < 0.05); compared with the model group, intracellular malondialdehyde content in the astragaloside IV group decreased (P < 0.05), the mRNA and protein expressions of osteocalcin, RUNX2, and type I collagen were elevated (P < 0.05), the mRNA expressions of ERK1/2 and AMPK were elevated (P < 0.05), and the protein expressions of p-AMPK and p-ERK1/2 were elevated (P < 0.05). Additionally, ERK inhibitors partially inhibited the above effects of astragaloside IV. To conclude, astragaloside IV can promote osteogenic differentiation of MC3T3-E1 cells by activating the ERK/AMPK pathway.
