PG - 201-8 LID - S1521-6616(12)00231-8 [pii] LID - 10.1016/j.clim.2012.09.006 [doi] AB - Expression of transcription factor Fli-1 is implicated in the development of glomerulonephritis. Fli-1 heterozygous knockout (Fli1(+/-)) NZM2410 mice, a murine model of lupus, had significantly improved survival and reduced glomerulonephritis. In this study, we found that infiltrated inflammatory cells were significantly decreased in the kidneys from Fli-1(+/-) NZM2410 mice. The expression of monocyte chemoattractant protein-1 (MCP-1) was significantly decreased in kidneys from Fli-1(+/-) NZM2410 mice. The primary endothelial cells isolated from the kidneys of Fli-1(+/-) NZM2410 mice produced significantly less MCP-1. In endothelial cells transfected with specific Fli-1 siRNA the production of MCP-1 was significantly reduced compared to cells transfected with negative control siRNA. By Chromatin Immunoprecipitation (ChIP) assay, we further demonstrated that Fli-1 directly binds to the promoter of the MCP-1 gene. Our data indicate that Fli-1 impacts glomerulonephritis development by regulating expression of inflammatory chemokine MCP-1 and inflammatory cell infiltration in the kidneys in the NZM2410 mice.
