摘要
导读:糖尿病肾病(DN)的病理生理从根本上依赖于肾小球内皮细胞(GECs),它是肾小球滤过屏障的重要组成部分。本研究旨在通过结合微阵列和单细胞测序数据集分析,确定与DN中gec功能障碍相关的生物标志物候选物。方法:从Gene expression omnibus (GEO)数据库下载微阵列数据集GSE30528。采用加权基因共表达网络分析(WGCNA)筛选糖尿病肾病(DKD)的关键基因集。然后使用最小绝对收缩和选择算子(LASSO)逻辑回归确定候选生物标志物。单细胞测序数据(GSE131882)用于探讨对照组和DKD组肾小球内皮生物学功能的差异。在受试者工作特征(ROC)曲线中检验所选生物标志物的诊断效率。此外,我们使用单样本基因集富集分析(ssGSEA)来比较DKD组和对照组之间的免疫细胞浸润。采用RT-PCR验证所选基因在高糖刺激下培养肾小球内皮细胞中的表达。结果:最终选择磷酸酶和肌动蛋白调节因子4 (PHACTR4)作为DKD中关键的gec相关生物标志物。通过RT-PCR进一步验证了高糖刺激下人肾小球内皮细胞(HGECs)中PHACTR4 mRNA表达的显著下调。PHACTR4的降低与内皮细胞增殖异常和新生血管生成有关。此外,免疫浸润分析显示,PHACTR4与炎症浸润呈负相关,特别是与活化的CD4和CD8 T细胞、B细胞和肥大细胞等促炎细胞呈负相关,表明PHACTR4下调可能加剧炎症反应。结论:PHACTR4是一种潜在的DKD诊断标志物,在DKD异常肾小球内皮增生和炎症中起重要作用。DOI: 10.52547 / ijkd.7858。
期刊介绍:
The Iranian Journal of Kidney Diseases (IJKD), a peer-reviewed journal in English, is the official publication of the Iranian Society of Nephrology. The aim of the IJKD is the worldwide reflection of the knowledge produced by the scientists and clinicians in nephrology. Published quarterly, the IJKD provides a new platform for advancement of the field. The journal’s objective is to serve as a focal point for debates and exchange of knowledge and experience among researchers in a global context. Original papers, case reports, and invited reviews on all aspects of the kidney diseases, hypertension, dialysis, and transplantation will be covered by the IJKD. Research on the basic science, clinical practice, and socio-economics of renal health are all welcomed by the editors of the journal.
