ABSTRACT
Objective In order to explore the effect of 25-(OH)D3 on monocyte chemoattratant protein (MCP)-1 expression from patients with system lupus erythematosus (SLE),we detected the level of active vitamin D and the expression of MCP-1 mRNA in patients with SLE,and analyzed the correlation between them.Methods The level of serum 25-(OH)D3 and mRNA expression of MCP-1 in 154 SLE patients and 31 healthy individuals were detected by enzyme-linked immuno sorbent assay (ELISA) and real time quanti-tative pol ymerase chain reaction (PCR) respectively.We also analyzed the correlation between serum 25-(OH)D3 level and the expression of MCP-1 mRNA,then analyzed the function of 25(OH)D3 on the regula-tion of MCP-1 mRNA expression in vitro.The differences between the two groups were tested by t-test and x2 test,multiple data were tested by one-way ANOVA and the correlation was analyzed by Pearson's correlation,all data were analyzed by statistical product and service solutions (SPSS) 17.0 software.Results The serum 25(OH)D3 levels in SLE group (20±11) ng/ml was significantly lower than normal control group (29±11) ng/ml (t=4.198,P<0.01),and the ratio of the serum levels of vitamin D deficiency in SLE group were significantly higher than that of normal control group [55.8%(86/154) vs 22.6%(7/31),x2=11.421,P=0.001].The expression level of MCP-1 mRNA in PBMCs from the normal control group was significantly lower than the SLE group (1.14±0.27 vs 1.44± 0.31,t=3.277,P=0.001),serum 25(OH)D3 level and MCP-1 mRNA expression in patients with SLE PBMCs were significantly negatively correlated (r=-0.289,P<0.01).Further study found that 25-(OH)D3 inhibited MCP-1 mRNA expression in PBMCs from SLE patients depending on the concentration.Conclusion The decreased 25-(OH)D3 level and up-regulated MCP-1 mRNA expression suggestthat MCP-1 may play an important role in SLE pathological process.
