文题释义:
MicroRNAs:MicroRNAs(miRNAs)是真核生物中发现的一类内源性的具有调控功能的非编码RNA,它的一个重要的生物学功能是广泛参与骨关节炎的炎症反应过程。
NF-κB/p38 MAPK信号通路:NF-κB是一种与炎症因子产生、细胞增殖、细胞外基质交联和细胞凋亡密切相关的转录因子,参与多种炎症的信号转导,在细胞中最常见的作用形式为NF-κB p65及NF-κB p50。p38MAPK信号转导通路参与基质金属蛋白酶的表达。骨关节炎关节滑膜及软骨细胞内的肿瘤坏死因子α、白细胞介素1β等均可以激活p38MAPK,后者可通过磷酸化而激活活化剂蛋白1,活化的活化剂蛋白1可以结合到基质金属蛋白酶1、基质金属蛋白酶3、基质金属蛋白酶13等相应基因启动区,从而启动基质金属蛋白酶过表达。
摘要
背景:
前期研究表明独活寄生汤可有效抑制膝骨关节炎炎症反应,但其具体机制尚不明确。
目的:观察独活寄生汤对膝骨关节炎大鼠软骨、滑膜miR-146a/-155-NF-κB/p38 MAPK信号通路相关因子的影响。
方法:SD雄性大鼠36只,购于上海斯莱克实验动物有限责任公司。实验方案经福建中医药大学动物实验伦理委员会批准,批准号为[2018]福中医伦理审字第(014)号。大鼠适应性喂养1周后,随机分为空白组(12只)和造模组(24只)。造模组采用改良Hulth法于大鼠右膝关节复制膝骨关节炎模型,造模后1周将造模大鼠随机分为模型组(12只)和实验组(12只)。空白组和模型组给予生理盐水10 mL/(kg•d)灌胃;实验组给予独活寄生汤9.3 g/(kg•d)灌胃。治疗3个月后,麻醉后切取大鼠右膝关节滑膜组织,ELISA法检测诱导型一氧化氮合酶、环氧合酶2、基质金属蛋白酶3和基质金属蛋白酶13含量变化;取大鼠软骨组织,免疫组织化学法检测NF-κB p65和p38 MAPK蛋白表达;Real-time PCR法检测miR-146a、miR-155、NF-κB p65和p38 MAPK基因表达。
结果与结论:①Real-time PCR结果表明独活寄生汤能抑制miR-155、NF-κB p65和p38 MAPK基因表达,促进miR-146a基因表达(P < 0.01);②免疫组织化学结果与Real-time PCR结果趋势一致,即独活寄生汤能抑制NF-κB p65和p38 MAPK蛋白表达(P < 0.01);③ELISA结果显示独活寄生汤可有效抑制诱导型一氧化氮合酶、环氧合酶2、基质金属蛋白酶3和基质金属蛋白酶13表达;④结果提示,独活寄生汤可通过调控miR-146a/-155-NF-κB/p38 MAPK信号通路,抑制膝骨关节炎炎症反应,从而起到治疗膝骨关节炎作用。

Abstract:

BACKGROUND: Preliminary study has shown that Duhuo Jisheng Decoction can effectively inhibit inflammatory reaction in knee osteoarthritis. But its underling mechanism remains unclear.   
OBJECTIVE: To observe the effect of Duhuo Jisheng Decoction on the related regulatory factors in miR-146a/-155-NF-κB/p38 MAPK signaling pathway in cartilage and synovium of rats with knee osteoarthritis.
METHODS: Thirty-six male rats were provided by Shanghai Slack Laboratory Animals Co., Ltd. The study was approved by the Experimental Animal Ethics Committee of Fujian University of Traditional Chinese Medicine, approval number: [2018] (014). After 1 week of acclimation, the rats were randomly divided into blank group (n=12) and model group (n=24). Osteoarthritis model was induced in rat right knees by modified Hulth method. One week later, the rat models were randomly divided into model control group (n=12) and experiment group (n=12). The blank and model control groups received an equivalent amount of normal saline (10 mL/kg•d) intragastrically. The experiment group received a clinical oral dose of Duhuo Jisheng Decoction (9.3 g/kg•d) intragastrically. After three months of treatment, the animals were sacrificed and synovial tissue and cartilage tissue were obtained. The contents of inducible nitric oxide synthase, cyclooxygenase-2, matrix metalloproteinase 3 and matrix metalloproteinase 13 were measured by ELISA. The protein levels of nuclear factor-κB p65 and p38 mitogen-activated protein kinase were detected by immunohistochemistry. The mRNA expression levels of miR-146a, miR-155, nuclear factor-κB p65 and p38 mitogen-activated protein kinase were tested by real-time PCR.
RESULTS AND CONCLUSION: (1) Real-time PCR results suggest that Duhuo Jisheng Decoction could inhibit the mRNA expression of miR-155, nuclear factor-κB p65 and p38 mitogen-activated protein kinase, and promote miR-146a mRNA expression (P < 0.01). (2) The results of immunohistochemistry were in agreement with the results of real-time PCR, indicating that Duhuo Jisheng Decoction could inhibit the protein expression of nuclear factor-κB p65 and p38 mitogen-activated protein kinase (P < 0.01). (3) ELISA results manifest that Duhuo Jisheng Decoction could effectively inhibit the expression of inducible nitric oxide synthase, cyclooxygenase-2, matrix metalloproteinase 3 and matrix metalloproteinase 13. (4) These results suggest that Duhuo Jisheng Decoction can inhibit the inflammatory reaction in knee osteoarthritis by regulating the miR-146a/-155-NF-κB/p38 MAPK signaling pathway, which may, in part, explain its clinical efficacy in the treatment of knee osteoarthritis.
