Figure Lengend Snippet: Changed mitochondrial mass in PPARα –/– (PKO) mouse brain endothelial cells. A and B: Representative Western blot analyses for translocase of outer mitochondrial membrane 20 (TOMM20), peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), and β-actin and densitometry quantification. Data are expressed as means ± SEM ( B ). n = 3 ( B ). ∗ P < 0.05 ( t- test). BSA, bovine serum albumin; NS, no significant difference; Pal, palmitate; WT, wild type.
