Effect of nitric oxide (NO) donor (NOC) treatment on Wnt5a and fibrosis factor expression of the glomerular mesangium in diabetic kidneys. Representative histology photographs of renal tissue (a) before and (b) after dissection of glomerular mesangium. NO donor treatment attenuated (c) transforming growth factor (TGF)-β1 and (d) fibronectin expression coincided with (e) reduced Wnt5a and (f) β-catenin messenger ribonucleic acid expression in the glomerular mesangium. Renal glomerular mesangium in rat kidneys were harvested by laser capture microdissection. DM, diabetic rats; NC, control group. Data were expressed as mean ± #P < 0.05 vs control group, +P < 0.05 vs NO donor treatment group. Specimens were observed under magnification ×400.
