地塞米松对系统性红斑狼疮阴虚内热证患者外周血单一核细胞基因表达谱的影响

目的 探讨地塞米松对系统性红斑狼疮(SLE)阴虚内热证患者外周血单一核细胞(PBMC)基因表达谱的影响.方法 用地塞米松孵化SLE阴虚内热证患者PBMC,收集孵化后细胞进行PBMC的基因表达谱检测.结果 地塞米松上调85个PBMC基因,下调126个PBMC基因.结论 地塞米松调控SLE阴虚内热证患者PBMC的基因所属功能簇众多,基因编码的功能蛋白分布细胞多个部位,不是所有基因调控结果均有利于SLE缓解,一些基因调控作用对研究地塞米松治疗SLE的机制有帮助.

Abstract：

Objective To observe the influence of dexamethasone on the gene expression profiling of PBMCs from patients with internal heat due to Yin deficiency-type SLE. Methods The PBMCs from 3 patients with internal heat due to Yin deficiency-type SLE were incubated with dexamethasone of 10-6 g/L for 48 hours followed by the detection of gene expression profiling of PBMCs by a GeneChip. Results The incubation with dexamethasone upregulated the expressions of 85 genes and downregulated those of 126 genes in PBMCs from the SLE patients. Conclusions Dexamethasone can regulate the expressions of numerous clusters of genes in PBMCs from patients with internal heat due to Yin deficiency-type SLE, and functional proteins encoded by these genes are located at various organelles and regions of cells. Not all the results of gene regulation by dexamethasone favor the relief of SLE. To study the regulation of genes may be beneficial to the elucidation of mechanisms underlying the therapeutic effect of dexamethasone on SLE.
