Eicosapentaenoic acid ameliorates diabetic nephropathy of type 2 diabetic KKAy/Ta mice: Involvement of MCP-1 suppression and decreased ERK1/2 and p38 phosphorylation

摘要

Background. Previous studies reported that eicosapentaenoic acid (EPA) was effective against any renal diseases including diabetic nephropathy. Monocyte chemoattractant protein-1 (MCP-1) is a regulating macrophage recruitment protein, which is up-regulated in patients with diabetic nephropathy. The objectives of the present study were to evaluate the effects of EPA including renal MCP-1 expression in diabetic KKAy/Ta mice, MCP-1 production and signal transduction in mouse mesangial cells (MMCs).
