Lupus nephritis (LN) is a severe complication of systemic lupus erythematosus (SLE). There is a great interest in using microRNAs (miRNAs) as diagnostic and prognostic biomarkers in autoimmune diseases.
This study evaluated miR-16, miR-21, miR-141, miR-146a, and miR-155 expression levels in peripheral blood mononuclear cells (PBMCs) of 55 female SLE patients with absent, inactive, or active nephritis, and 30 healthy controls (HCs) using quantitative polymerase chain reaction.
MiR-21 and miR-155 levels were significantly greater in the active nephritis group than in the absent, inactive or HC groups. Moreover, receiver operating characteristic and logistic regression analyses revealed miR-21 and miR-155 were significant risk factors for LN.
Overexpression of miR-21 and miR-155 in PBMCs may participate in LN pathophysiology and these miRNAs could be used as biomarkers for the condition.
狼疮性肾炎(LN)是系统性红斑狼疮(SLE)的一种严重并发症。人们对将微小RNA(miRNA)用作自身免疫性疾病的诊断和预后生物标志物有着浓厚兴趣。
本研究采用定量聚合酶链反应评估了55例无肾炎、肾炎不活动或活动的女性SLE患者以及30例健康对照(HC)外周血单个核细胞(PBMC)中miR-16、miR-21、miR-141、miR-146a和miR-155的表达水平。
活动期肾炎组的miR-21和miR-155水平显著高于无肾炎组、肾炎不活动组或健康对照组。此外,受试者工作特征曲线和逻辑回归分析显示,miR-21和miR-155是LN的显著危险因素。
PBMC中miR-21和miR-155的过表达可能参与LN的病理生理过程,这些miRNA可作为该疾病的生物标志物。
