摘要:

目的 探讨白刺花叶总生物碱(Sophora davidii Hance leaves total alkaloids,SDLTAs)的体外抗炎作用及可能的分子机制。 方法 采用脂多糖(LPS)诱导RAW264.7细胞炎症模型,给予不同浓度(50、100、200 μg/mL)SDLTAs,Griess法检测SDLTAs对细胞NO表达的影响;ELISA法检测SDLTAs对细胞因子IL-6、TNF-α和IL-1β表达的影响;RT-qPCR法检测细胞中iNOS、NF-κB p65和IκBα mRNA的表达;Western blotting法检测细胞中p-p38、p-p65和p-JNK以及细胞核内NF-κB p65的蛋白表达。 结果 SDLTAs显著抑制LPS诱导的RAW264.7细胞炎症反应。SDLTAs极显著降低细胞中NO、IL-6、TNF-α和IL-1β的分泌(P < 0.01),极显著下调细胞中iNOS、NF-κB p65和IκBα mRNA的表达(P < 0.01),极显著降低细胞中p-p38、p-p65和p-JNK以及细胞核内NF-κB p65的蛋白表达(P < 0.01)。 结论 SDLTAs可通过调节MAPK/NF-κB信号通路发挥抗炎作用。

Abstract:

Objective To investigate the in vitro anti-inflammatory effects of Sophora davidii Hance leaves total alkaloids(SDLTAs)and possible molecular mechanisms. Methods The lipopolysaccharide (LPS)-induced inflammation model of RAW264.7 cells was used, and different concentrations of SDLTAs (50, 100 and 200 μg/mL) were administered, and the effect of SDLTAs on cellular NO expression was detected by the Griess method; ELISA method was used to detect the effect of SDLTAs on the expression of IL-6, TNF-α and IL-1β; The expression of iNOS, NF- κB p65 and IκBα mRNA was detected by RT-qPCR; Western blotting was used to detecte the expression of p-p38, p-p65 and p-JNK in the cells and NF- κB p65 in the nucleus. Results SDLTAs could significantly inhibit the LPS-induced inflammatory response in RAW264.7 cells. SDLTAs significantly decreased the secretion of NO, IL-6, TNF-α and IL-1β in cells (P < 0.01), and significantly decreased the mRNA expressions of iNOS, NF-κB p65 and IκBα in cells (P < 0.01). Significantly decreased the protein expression of p-p38, p-p65 and p-JNK in cells and NF-κB p65 in nucleus (P < 0.01). Conclusion SDLTAs can exert anti-inflammatory effects by regulating the MAPK/NF-κB signalling pathway.
