Expression level of osteopotin and lupus nephritis / 中国免疫学杂志

ABSTRACT

Objective:To explore the role of osteopotin in lupus nephritis (LN).Methods:Sera osteopotin( OPN )levels were measured by enzyme linked immunosorbent assay in 90 patients with systemic lupus erythematosus (SLE),15 non-SLE patients with renal impairment,and 30 healthy volunteers.OPN mRNA expression in peripheral blood mononuclear cells (PBMCs) was also investigated with reverse transcription-polymerase chain reaction semi-quantitative method.Results:The expression of OPN was significantly higher in active LN groups than in all other groups(P0.05).Conclusion:The expression of PBMCs OPN mRNA is up regulation in active SLE.Meanwhile,its expression levels are correlated with the activity of LN.
