..., leading to a reduction in filtration barrier function. Effacement is typically associated with the presence of proteinuria in focal segmental glomerulosclerosis, minimal change disease, and diabetes. It is thought to be due to a breakdown in the actin cytoskeleton of the foot processes, complex...

... podocytes to silence nestin expression. F-actin arrangement within cultured podocytes was investigated by immunofluorescence, while the apoptosis rate was examined by both Hoechst stain and flow cytometry. Results: In the PAN-induced rat nephrosis model, podocyte nestin expression was increased...

... by morphology and alpha smooth muscle actin (α-SMA) immunostaining at the light and electron microscope level. Results were related to staining for interstitial leukocytes and collagen III. A control group consisted of 6 normal renal transplant donors from whom biopsy specimens were taken at the time...

... into the renal cortex of Sprague-Dawley rats weighing 270 g. Saline was substituted in a control group. The animals were sacrificed at five time points up to day 24 (E. coli n = 8, controls n = 3 each interval). Myofibroblasts were identified by morphology and immunohistochemistry for alpha smooth muscle actin...
