Fig. 2From: Angiotensin II-induced podocyte apoptosis is mediated by endoplasmic reticulum stress/PKC-δ/p38 MAPK pathway activation and trough increased Na+/H+ exchanger isoform 1 activitya Immunofluorescence staining of podocin in conditionally immortalized mouse podocytes. Podocin is labeled in red and DAPI (nuclei) in blue. Original magnification, × 630; bar, 20 μm; n = 3. b Representative bands of podocin and angiotensin II receptor 1 (AT1) proteins expression.
