IgA肾病患者CpG岛组蛋白H3赖氨酸4三甲基化水平的研究
CpG array analysis of histone H3 lysine 4 trimethylation in patients with IgA nephropathy
摘要
Abstract
Objective To investigate the aberrance of histone H3 lysine 4 trimethylation (H3K4me3) in patients with IgA nephropathy (IgAN). Methods In 15 patients with IgAN and 15 healthy volunteers, H3K4me3 variations in peripheral blood mononuclear cells (PBMCs) were analyzed using chromatin immunoprecipitation and microarray analysis (ChlP-chip). ChIP real-time PCR was used to validate the microarray results. Quantitative real-time PCR (qRT-PCR) was carried out to examine the correlations between the mRNA expression profiles and H3K4me3 levels. Results We identified 83 genes that displayed significant H3K4me3 differences in IgAN patients compared with healthy subjects. Among them, 39 genes showed increased H3K4me3 and 44 genes had decreased H3K4me3 levels. The results of ChIP real-time PCR were well consistent with the microarray data. Quantitative RT-PCR revealed the correlations between the mRNA expressions and the methylation levels of H3K4me3. Conclusion IgAN patients have significant alterations in H3K4me3, and the genes with aberrant H3K4me3 may provide insights into the pathogenesis of IgAN.关键词
