Figure 5: Administration of aldosterone aggravated podocyte injury.

(a,b) Representative images of nephrin (a) and podocin (b) expression by immunofluorescent study in a juxtamedullary glomerulus. Scale bars, 50 μm. (c) Transmission electron microscopic microphotographs of a juxtamedullary glomerulus. ALDO pod GC-A cKO mice exhibited mild thickening GBM and foot process effacement and its injury was ameliorated with the administration of FR167653. (d) Immunohistochemical staining for phosphorylated p38 MAPK. Arrows, phospho-p38 MAPK positive cells. Scale bars, 50 μm.
