Figure 4 Effects of peroxisome proliferators-activated receptor-alpha activator on messenger ribonucleic acid (mRNA) expression of interleukin (IL)-6 (A), cyclooxygenase (COX)-2 (B), vascular cell adhesion molecule (VCAM)-1 (C), and monocyte chemoattractant protein (MCP)-1 (D) in the left ventricle of deoxycorticosterone acetate-salt hypertensive rats. For each, the mRNA levels are compared among three groups: UN control (n = 6), DOCA-V (n = 7), and DOCA-F (n = 8). Each column and bar represent the mean value ± SEM. *p < 0.05 vs. UN control, **p < 0.01 vs. UN control, p < 0.05 vs. DOCA-V, p < 0.01 vs. DOCA-V. Abbreviations as in Figure 1.
