| Outline of Final Research Achievements |
This study examined the therapeutic effects for diabetic nephropathy targeting estrogen-related receptor-alpha (ERRa), which involves mitochondrial function and angiogenesis. In glomeruli from type 1 diabetic mouse model, expression of ERRa was increased on podocytes. Cultured podocytes treated with ERRa antagonist showed to decrease expression of VEGF in high-glucose condition. Diabetic ERRa knockout mice could not reduce proteinuiria compared to wild type diabetic mice. However, kaempferol, which is known as ERRa inverse agonist, suppressed proteinuria in diabetic mouse model. These results suggest the potential involvement of ERRa in the progression of diabetic nephropathy.
