Abstract

Background: MicroRNAs (miRs) are noncoding gene regulators that may have a role as diagnostic or prognostic biomarkers in systemic lupus erythematosus (SLE).

Aim: To measure the blood levels of miR-146a, miR-126 and miR-30a in Sudanese SLE patients and to investigate their potential role in disease pathogenesis and utility as biomarkers for SLE.

Material and Methods: A total of 48 SLE patients and 20 matched healthy individuals were enrolled in this study. SLE disease activity index (SLEDAI) was assessed. The blood levels of miR-146a, miR-126 and miR-30a were determined by Real-time polymerase chain reaction (PCR) in all participants. For γ-INF and IL-2 were analyzed by ELISA, and CD markers were used flowcytometery.

Results: The mean age of the patients was 31.5 ± 8.5 years with disease duration >5 years. In SLE patients, the mean blood level fold changes of miR-146a (0.33±0.277; P0.305) compared to controls. Down regulation of miR-146a increase expression of γ-INF (p < 0.002), whereas the up regulation of miR-126 increase expression of CD markers (p0.05) as no differences between the SLE patients and healthy control.

Conclusion: Circulating miR-146a and miR-126 could be a potential noninvasive biomarker in SLE. This study providing an overview of the current state of research on the role of miRNAs in the immune pathogenesis and regulation of SLE. Further studies are needed in miRNAs profiling expressions of SLE diseases.
