Fig. 3From: 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 activityRelative expression and representative bands of GRP 78 (a), phosphorylated eIF2-α (peIF2-α) (b) and phosphorylated pPKC-δ (c) in control and treated podocytes. GAPDH was used as an internal control; values represent the mean ± SEM (n = 4–5 experiments)Back to article page
