目的
2
探讨棕矢车菊素激活腺苷一磷酸活化的蛋白激酶(AMPK)/NOD样受体蛋白3(NLRP3)信号通路对大鼠骨关节炎(OA)的影响。
方法
2
大鼠随机分为OA组、棕矢车菊素(33.33 mg/kg)组、AMPK抑制剂(Compound C,20 mg/kg)组、棕矢车菊素(33.33 mg/kg)+Compound C(20 mg/kg)组和假手术组,每组12只。除假手术组外,其余各组大鼠均通过改良Hulth法建立OA模型。建模成功后,各组大鼠灌胃相应剂量的棕矢车菊素或生理盐水,且腹腔注射相应剂量的Compound C或生理盐水,每天1次,持续8周。末次给药24 h后,检测各组大鼠膝关节肿胀度;观察大鼠膝关节软骨组织的病理并进行Mankin评分;检测大鼠膝关节软骨组织中肿瘤坏死因子α(TNF-α)、白细胞介素18(IL-18)、IL-6水平,胶原蛋白Ⅱ(collagen Ⅱ)、聚集蛋白聚糖(ACAN)、血小板反应蛋白解整合素金属肽酶5(ADAMTS5)蛋白表达,以及磷酸化AMPK(p-AMPK)、AMPK、NLRP3、裂解的胱天蛋白酶1(cleaved-caspase-1)、裂解的IL-1β(cleaved-IL-1β)蛋白表达。
结果
2
与OA组比较,棕矢车菊素组大鼠软骨组织缺损现象有所缓解,软骨基质染色加深,软骨细胞数量增多;膝关节肿胀度、Mankin评分和膝关节软骨组织中TNF-α、IL-18、IL-6水平以及ADAMTS5、NLRP3、cleaved-caspase-1、cleaved-IL-1β蛋白表达水平均显著降低或下调,collagen Ⅱ、ACAN蛋白表达水平和AMPK磷酸化均显著升高或上调(
P
<0.05)。Compound C显著逆转了棕矢车菊素对OA大鼠上述指标的改善作用(
P
<0.05)。
结论
2
棕矢车菊素可能通过调控AMPK/NLRP3信号通路来抑制OA大鼠炎症反应及细胞外基质降解。
OBJECTIVE
2
To investigate the effects of jaceosidin on osteoarthritis (OA) of rats by regulating adenosine monophosphate-activated protein kinase (AMPK)/NOD-like receptor protein 3 (NLRP3) pathway.
METHODS
2
Rats were randomly separated into OA group, jaceosidin group (33.33 mg/kg), AMPK inhibitor (Compound C, 20 mg/kg) group, jaceosidin (33.33 mg/kg)+Compound C (20 mg/kg) group, and sham operation group, with 12 rats in each group. Except for the sham operation group, the OA model was induced with modified Hulth method in all other groups. After successful modeling, they were given a relevant dose of jaceosidin or normal saline intragastrically, and Compound C or normal saline intraperitoneally, once a day, for consecutive 8 weeks. Twenty-four h after the last medication, the degree of knee joint swelling in rats from each group was measured. The pathological changes of the articular cartilage tissue in the knee joints, and the Mankin score were assessed. The levels of tumor necrosis factor-α (TNF-α), interleukin-18 (IL-18), and IL-6, as well as the protein expressions of collagen Ⅱ, aggrecan (ACAN), and a disintegrin and metalloproteinase with thrombospondin 5 (ADAMTS5), phosphorylated AMPK (p-AMPK), AMPK, NLRP3, cleaved-caspase-1, and cleaved-IL-1β were detected in the articular cartilage tissue of rats’ knees.
RESULTS
2
Compared with OA group, the cartilage tissue defect of jaceosidin group was relieved, the cartilage matrix staining was deepened, and the number of chondrocytes was increased. Knee swelling, Mankin score, the levels of TNF-α, IL-18 and IL-6, and protein expressions of ADAMTS5, NLRP3, cleaved-caspase-1 and cleaved-IL-1β in knee cartilage were significantly decreased or down-regulated. Protein expressions of collagen Ⅱ, ACAN and phosphorylation level of AMPK were significantly increased or up-regulated (
P
<0.05). Compound C significantly reversed the improvement effects of jaceosidin on the above indexes of OA rats (
P
<0.05).
CONCLUSIONS
2
Jaceosidin may inhibit inflammation and extracellular matrix degradation in OA rats by regulating the AMPK/NLRP3 signaling pathway.
