摘要:


文题释义:

Wnt/β-catenin信号通路是一条在生物进化中极为保守的通路。在正常细胞中,β-catenin只是作为一种细胞骨架蛋白在胞膜处与E-cadherin形成复合体对维持同型细胞的黏附、防止细胞的移动发挥作用。只有当细胞外Wnt信号分子与细胞膜上特异性受体Frizzled蛋白结合激活胞内散乱的蛋白导致GSK-3β失活,进而使β-catenin磷酸化降解,当解离的β-catenin达到一定浓度时细胞功能发生异常,表现为病理状态。

独活寄生汤拆方由中药独活、寄生、防风、秦艽、细辛、肉桂心组成具有祛风湿、止痹痛的祛湿止痛方,处方比例为322222

背景:Wnt/β-catenin信号通路在骨关节炎的炎症反应病理过程中扮演着重要角色,而独活寄生汤拆方可有效抑制软骨细胞的炎症反应,但其具体作用机制尚不明确。有待进一步深入研究。

目的探讨独活寄生汤拆方是否可以通过调控Wnt/β-catenin信号通路抑制由脂多糖诱导的软骨细胞炎症反应。

方法SD雄性大鼠,采用机械型胶原酶消化法获取膝关节软骨细胞,倒置相差显微镜观察软骨细胞的形态结构,型胶原免疫组化鉴定软骨细胞。用不同质量浓度的独活寄生汤拆方(300400500 mg/L)干预由脂多糖(10 μg/L)诱导的软骨细胞炎症模型,干预8 h后,采用酶联免疫吸附(ELISA)法测定各组软骨细胞培养液中白细胞介素、肿瘤坏子因子α水平,确定独活寄生汤拆方干预浓度。将第2代软骨细胞分为4组:空白组含正常培养液;模型组培养液中含10 μg/L脂多糖;独活寄生汤拆方组培养液中含10 μg/L脂多糖和400 mg/L独活寄生汤拆方;抑制剂组培养液中含10 μg/L脂多糖和10 mg/L Dickkopf-1。干预8 h后,采用Western blot法检测β-cateninWnt-4Frizzled-2GSK-3βCKI-ε的蛋白表达量。

结果与结论软骨细胞鉴定:获取的软骨细胞型胶原免疫组化染色胞浆呈棕黄色,具备软骨细胞典型特征;②ELISA结果显示:模型组培养液中白细胞介素和肿瘤坏子因子α水平均高于空白组,400 mg/L独活寄生汤拆方干预后两种炎症因子水平较模型组显著降低,所以确定独活寄生汤拆方干预浓度为     400 mg/L③Western blot结果显示:模型组β-cateninWnt-4Frizzled-2CKI-ε的蛋白表达量均高于空白组,而GSK-3β蛋白表达量低于空白组;独活寄生汤拆方组和抑制剂组β-cateninWnt-4Frizzled-2CKI-ε蛋白表达量低于模型组,而GSK-3β蛋白表达量高于模型组。结果表明:独活寄生汤拆方可以通过调控Wnt/β-catenin信号通路抑制脂多糖诱导的软骨细胞炎症反应。

Abstract:

BACKGROUND: ThePrevious studies have shown that the Wnt/β-catenin signaling pathway plays an important role in the pathogenesis and prognosis of chondrocyte inflammation, and the effective inhibition of chondrocyte inflammatory response byDuhuo Jisheng Decoction Disassembled Prescription remains to be further studied.

OBJECTIVE: To investigate whether Duhuo Jisheng Decoction Disassembled Prescription can inhibit the inflammatory response of chondrocytes induced by lipopolysaccharide via the Wnt/β-catenin signaling pathway.
METHODS: Male Sprague-Dawley rats were used to obtain knee joint chondrocytes by mechanical-type II collagenase digestion. The morphology and structure of chondrocytes were observed by inverted phase contrast microscope. Chondrocytes were identified by type II collagen immunohistochemistry. Duhuo Jisheng Decoction Disassembled Prescription with different mass concentrations (300, 400, 500 mg/L) was used to deal with the chondrocyte inflammation model induced by lipopolysaccharide (10 μg/L). After 8 hours of intervention, the ELISA method was used to determine the expression of interleukin-1β and tumor necrosis factor-α in the cell culture fluid to determine the intervention concentration of Duhuo Jisheng Decoction Disassembled Prescription. The second-generation chondrocytes were divided into four groups, followed by culture with normal medium in blank group, 10 μg/L lipopolysaccharide in model group, 10 μg/L lipopolysaccharide plus 400 mg/L Duhuo Jisheng Decoction Disassembled Prescription in 400 mg/L Duhuo Jisheng Decoction Disassembled Prescription group, and 10 μg/L lipopolysaccharide plus 10 mg/L Dickkopf-1 in inhibitor group. After 8 hours of intervention, the expression levels of β-catenin, Wnt-4, Frizzled-2, GSK-3β and CKI-ε were detected by western blot.
RESULTS AND CONCLUSION: Chondrocyte identification results showed that the cytoplasm of chondrocytes was brown-yellow, with the typical characteristics of chondrocytes. ELISA results showed that the expression levels of interleukin-1β and tumor necrosis factor-α were higher in the model group than in the blank group, and the expression levels of interleukin-1β and tumor necrosis factor-α were significantly reduced in the 400 mg/L Duhuo Jisheng Decoction Disassembled Prescription group compared with the model group. Therefore, the intervention concentration of Duhuo Jisheng Decoction Disassembled Prescription was determined to be 400 mg/L. The results of western blot showed that the expression levels of Wnt-4, Frizzled-2, β-catenin and CKI-ε in the model group were higher than those in the blank group, whereas the expression of GSK-3β protein was lower than that in the blank group. The expression levels of Wnt-4, Frizzled-2, β-catenin and CKI-ε proteins in the Duhuo Jisheng Decoction Disassembled Prescription group and the inhibitor group were lower than those in the model group, whereas the protein expression level of GSK-3β was higher than that in the model group. All the findings indicate that Duhuo Jisheng Decoction Disassembled Prescription can inhibit lipopolysaccharide-induced chondrocyte inflammation by regulating the Wnt/β-catenin signaling pathway.
