AIM The objective of this study was to identify the association between genotypes of miR-146a rs2910164 and expression of TRAF6 as well as the risk of lupus nephritis (LN). RESULTS A total of 567 systemic lupus erythematosus patients both with and without LN were included in the study. The luciferase activity of cells that carried miR-146a mimics was much lower than control and the miR-146a mRNA expression with the GG SNP was significantly overexpressed compared with that in GC and CC groups. Expressions of TRAF6 mRNA and protein with GG were markedly lower than those in GC and CC groups. Mesangial cells treated with miR-146a inhibitors displayed higher expression of TRAF6 mRNA and protein compared with scramble control, miR-146a mimics and TRAF6 siRNA groups. CONCLUSION Rs2910164 is associated with the risk of LN and could function as a therapeutic target of the disease.
