Abstract

MicroRNAs (miRNAs) play important roles in the pathogenesis of systemic lupus erythematosus (SLE). Here, we investigated the serum miRNAs expression profiles in the serum of SLE and healthy controls, and identified the potential serum biomarkers for SLE. We screened and identified the differentially expressed miRNAs such as miR-371b-5p, miR-5100, miR-146a-5p among active SLE, inactive SLE and healthy controls based on the miRNAs expression array. Furthermore, the results of RT-qPCR confirmed that miR-371b-5p and miR-5100 expression was different among active SLE, inactive SLE and healthy controls. Moreover, we performed in a large cohort which we validated that expression of miR-371b-5p and miR-5100 was increased significantly in the serum of SLE compared with healthy controls and rheumatoid arthritis (RA), and was also higher in active SLE than that in inactive SLE. In addition, we found the associations between the expression levels of miR-371b-5p and miR-5100 and these clinical parameters of SLE. These results suggested that miR-371b-5p and miR-5100 may act as serum biomarkers for SLE.
