摘要:

拟探讨中药白头翁汤方剂(PD)对细菌内毒素(LPS)损伤的治疗作用。将内皮细胞培养至单层融合状态,加入LPS和白头翁汤作用12 h后,提取3个处理组的总RNA。采用Affymetrix Rat Genome 230 2.0 Array芯片检测,读取各组基因表达的变化情况并进行生物学分析。选取5个与炎症反应相关的差异表达基因,采用嵌合荧光法进行Real-time RT-PCR反应。结果显示:与空白组相比,LPS组产生69个差异表达基因,其中上调基因36个,下调基因33个;与LPS组相比,LPS-PD组产生578个差异表达基因,其中上调基因566个,下调基因12个;与空白组相比,LPS-PD组产生122个差异表达基因,其中上调基因93个,下调基因29个。5个目标基因Il1α、Il6、Edn1、Tnfsf11和Ptges的Real-time RT-PCR检测结果依次为9.78、1.76、1.43、2.98和2.12,对应的基因芯片检测结果分别是10.57、1.53、1.59、3.16和1.71,两者变化趋势相符。白头翁汤抗内毒素的药理机制可能在于减少炎症因子的蛋白表达,抑制凋亡基因的启动,阻碍内毒素信号传导与受体激活,增加机体能量代谢和蛋白质合成。

Abstract:

A high-throughput and efficient Affymetrix rat genome array was used to investigate the pharmacological mechanism of the traditional Chinese medicine, Pulsatillae Decoction (PD), used for the treatment of diseases induced by lipopolysaccharide (LPS). Endothelial cell was challenged with 1 μg·mL-1 LPS for 3 h, then treated with PD at a concentration of 1 mg·mL-1 for 12 h. Total RNA of each treated group was extracted from cultured endothelial cell for detection by the Affymetrix Rat Genome 230 2.0 Array. The samples from LPS group and blank control group were subjected to Real-time RT-PCR, using the chimeric fluorescence method. The results showed that in LPS group, 36 genes were upregulated and 33 genes were downregulated in comparison with Blank group; In LPS-PD group, 566 genes were upregulated and 12 genes were downregulated in comparison with LPS group, and 93 genes were upregulated and 29 genes were downregulated in comparison with Blank group. The RT-PCR ratios for the target genes Il1α, Il6, Edn1, Tnfsf11 and Ptges were 9.78, 1.76, 1.43, 2.98 and 2.12 respectively, which were very similar to the ratios determined by the gene chips (10.57, 1.53, 1.59, 3.16 and 1.71, respectively). These results indicate that PD could simultaneously reduce the translated level of inflammatory factors, suppress the transcription of apoptosis genes, accelerate the protein synthesis of organism and enhance the energy metabolism of cells, thus play the united antiendotoxin action.
