Attenuation of Armanni-Ebstein lesions in a rat model of diabetes by a new anti-fibrotic, anti-inflammatory agent, FT011

Abstract

Aims/hypothesis: A key morphological feature of diabetic nephropathy is the accumulation and deposition of glycogen in renal tubular cells, known as Armanni-Ebstein lesions. While this observation has been consistently reported for many years, the molecular basis of these lesions remains unclear. Methods: Using biochemical and histochemical methods, we measured glycogen concentration, glycogen synthase and glycogen phosphorylase enzyme activities, and mRNA expression and protein levels of glycogenin in kidney lysates from control and transgenic (mRen-2)27 rat models of diabetes that had been treated with and without a new anti-fibrotic agent, FT011. Results: Diabetic nephropathy was associat..
