摘要:

目的 探究孟鲁司特钠是否能通过影响PHD2/HIF-1α通路缓解哮喘小鼠气道炎症反应。 方法 通过卵清蛋白(OVA)诱导建立过敏性哮喘模型,将18只BALB/c雌性小鼠随机分为对照组(Con组)、哮喘组(OVA组)、孟鲁司特钠干预哮喘组(在OVA激发前1 h经口灌胃30 mg/kg孟鲁司特钠,Mon组)。HE染色检测小鼠肺部病理改变,血球分析仪和试剂盒测定肺部炎症细胞数量及细胞因子、乳酸和丙酮酸含量,RT-PCR和Western blot检测小鼠肺缺氧诱导因子-1α(HIF-1α)、脯氨酸羟化酶2(PHD2)、E-黏钙蛋白(E-cad)和p120 mRNA和蛋白表达量。 结果 与对照组比较,OVA组小鼠肺部嗜酸性粒细胞、淋巴细胞、中性粒细胞和单核细胞数量增多,白细胞介素-5(IL-5)、白细胞介素-13(IL-13)、补体因子D(CFD)及乳酸、丙酮酸的含量都显著升高,肺HIF-1α、PHD2、p120和E-cad的mRNA水平降低,而HIF-1α和PHD2蛋白表达上调,E-cad和p120蛋白表达下调(均P < 0.05),经孟鲁司特钠干预的Mon组小鼠肺部嗜酸性和单核细胞数量及CFD含量显著下降,乳酸和丙酮酸的含量基本恢复至正常,HIF-1α、PHD2、p120和E-cad的mRNA及蛋白表达量均得到有效改善。 结论 孟鲁司特钠可能通过调控PHD2/HIF-1α信号通路缓解过敏性哮喘小鼠肺部气道炎症反应。

Abstract:

Objective The study aimed to investigate whether montelukast sodium could alleviate airway inflammatory responses in asthmatic mice by affecting the PHD2/HIF?1α pathway. Methods An allergic asthma model was established by ovalbumin (OVA) induction, and 18 female BALB/c mice were randomly divided into a control group (Con group), an asthma group (OVA group), and an asthma group with montelukast sodium intervention (30 mg/kg montelukast sodium by oral administration 1 h before OVA challenge, Mon group). HE staining was used to analyze the pathological changes in the lungs of mice. Blood cell analyzer and kits were used to determine the number of inflammatory cells and the levels of cytokines, the content of lactic acid and pyruvic acid in the lungs, respectively. RT?PCR and Western blot were used to detect the mRNA and protein expression of HIF?1α, PHD2, E?cad and p120 in the lungs of mice. Results Compared with the Con group, there was a significant increase in the number of eosinophils, lymphocytes, neutrophils and monocytes, the levels of IL?5, IL?13, complement factor D (CFD) and contents of lactate and pyruvate in the lungs of mice in the OVA group. Lung HIF?1α, PHD2, p120 and E?cad mRNA levels were reduced, meanwhile HIF?1α and PHD2 protein expression were upregulated but E?cad and p120 protein expression were downregulated (all with P < 0.05). After montelukast sodium intervention, the number of eosinophils and monocytes and CFD expression were significantly decreased in the lungs of Mon group, the contents of lactate and pyruvate were basically restored to normal, and the mRNA and protein expression of HIF?1α, PHD2, p120 and E?cad were effectively improved. Conclusion Montelukast sodium could alleviate the airway inflammatory responses in the lungs of asthmatic mice by regulating the PHD2/ HIF?1α signaling pathway.
