Abstract
Abstract Childhood- onset systemic lupus erythematosus (cSLE) is a multisystem inflammatory disease that can lead to severe clinical conditions resulting in early comorbidities. Several genetic, environmental, and immunological factors are known to influence the onset of the disease. MiRNAs have been already considered as potential actors involved in the development and activity of the SLE. Thus, understanding the behavior of these regulators can contribute to clarify the inflammatory process affecting SLE patients. Among miRNAs, miR-125b-5p and miR-9-5p targeting NFKB1 and TRAF6 genes can be involved in the etio-pathogenesis of the disease by modulating inflammation. In this study we evaluated miR-9-5p and miR-125b-5p expression and its target genes NFKB1 and TRAF6 in peripheral blood samples (PBMC) from the 35 cSLE patients and 35 healthy controls. MiRNAs and gene target expression have been evaluated by using RT-PCR with specific TaqMan® probes. Both miR-9-5p [Fold Change (FC) = −2.21; p = 0.002] and miR-125b-5p (FC= −3.30; p < 0.0001) and NFKB1 (FC = −1.84; p < 0.001) were downregulated in cSLE patients, while TRAF6 was upregulated (FC = 1.80; p = 0.006) in cSLE patients when compared to controls. A significant correlation was found between miR-125b-5p and its target gene NFKB1 [Spearman (r) = 0.47; p = 0.023]. Our results showed miR-125b-5p and miR-9-5p differential expression in cSLE patients, possibly contributing to better understanding the role of these regulators in cSLE development and disease pathogenesis.
期刊介绍:
Autoimmunity is an international, peer reviewed journal that publishes articles on cell and molecular immunology, immunogenetics, molecular biology and autoimmunity. Current understanding of immunity and autoimmunity is being furthered by the progress in new molecular sciences that has recently been little short of spectacular. In addition to the basic elements and mechanisms of the immune system, Autoimmunity is interested in the cellular and molecular processes associated with systemic lupus erythematosus, rheumatoid arthritis, Sjogren syndrome, type I diabetes, multiple sclerosis and other systemic and organ-specific autoimmune disorders. The journal reflects the immunology areas where scientific progress is most rapid. It is a valuable tool to basic and translational researchers in cell biology, genetics and molecular biology of immunity and autoimmunity.
