Expression of the slit-diaphragm protein, nephrin, in experimental diabetic nephropathy: Differing effects of anti-proteinuric therapies

Abstract

Background. Mutations in the gene coding for the podocyte slit-pore membrane protein, nephrin, are responsible for the Finnish-type congenital nephrotic syndrome. The present study sought to examine whether nephrin expression may also be altered in experimental diabetes, and how such changes related to the development of proteinuria. In addition, the study also sought to examine nephrin expression in animals treated with different anti-proteinuric therapies. Methods. Nephrin gene expression and localization were examined in rats with streptozotocin-induced diabetes at 6 months duration (proteinuric phase) and at 7 days (pre-proteinuric phase). In addition, the effects of anti-proteinuric dru..
