Western blot of heart adipose tissue. A, Complement protein 3 (C3) and fatty acid-binding protein-4 (FABP4) in control (n = 3) versus SU/hyp (n = 3). Percentage of total protein from Western blot for C3 (B; P = 0.02) and FABP4 (C; P = 0.006). Actin was used as loading control. SU/hyp: rat model of pulmonary arterial hypertension using a subcutaneous injection of vascular endothelial growth factor receptor blocker (Sugen 5416) with subsequent exposure to hypoxic conditions. Asterisk indicates a statistically significant difference.
