| 摘要: |
| β-石竹烯(BCP)是一种双环倍半萜类化合物。为研究β-石竹烯在体外对脂多糖诱导炎症的作用效果及作用机制，利用β-石竹烯处理被脂多糖诱导的RAW264.7细胞炎症模型，用MTT法检测β-石竹烯对细胞活力的影响，用ELISA试剂盒检测IL-6、TNF-α炎症因子的含量变化，用qRT-PCR技术检测IL-6、TNF-α、IL-1β、MCP-1的mRNA含量变化，用Western blot检测NF-κB信号通路和JNK信号通路关键蛋白表达变化。结果显示β-石竹烯能够降低细胞中IL-6的含量和IL-6、TNF-α、IL-1β、MCP-1的表达，抑制炎症信号通路NF-κB和JNK。所以β-石竹烯可以通过抑制NF-κB和JNK信号通路，降低炎症因子的释放起到抗炎的效果。本研究为β-石竹烯活性的开发提供数据支持，并进一步为β-石竹烯应用于抗炎治疗方面提高理论依据。 |

| Abstract: |
| β -caryophyllene (BCP) is a dicyclic sesquiterpenoid compound. In order to study the anti-inflammatory effects and mechanism of β-caryophyllene in lipopolysaccharide (LPS) induced inflammatory, β-caryophyllene was used to treat RAW264.7 cell inflammatory model induced by LPS. The effects of β -caryophyllene on cell viability were detected by MTT assay, and the contents of IL-6 and TNF-α inflammatory factors were detected by ELISA kit. The mRNA levels of IL-6, TNF-α, IL-1β and MCP-1 were detected by qRT-PCR, and the proteins of NF-κB and JNK signaling pathways were detected by Western blot. The results showed that β-caryophyllene can decrease the contents of IL-6 and the mRNA levels of IL-6, TNF-α, IL-1β and MCP-1, and decrease the protein contents of P65 and PJNK in RAW264.7 cells. Overall, these results suggest that β-caryophyllene has the anti-inflammatory effects by decreasing the secretion of inflammatory cytokines Il-6, TNF-α, IL-1β and MCP-1 and inhibiting NF-κB and JNK signaling pathways. It provides the theoretical basis for developing the functional activity of β-caryophyllene, and furtherly provides a reference for the use of β-caryophyllene in the treatment of inflammation-related diseases. |
