Abstract

Atherogenic dyslipidemia and chronic inflammation appear strongly associated with residual cardiovascular disease (CVD) risk. Peroxisome proliferator–activated receptor α (PPARα) agonists, which exert both triglyceride-lowering and anti-inflammatory properties, are potential therapeutic candidates to target residual CVD risk. However, CVD outcome studies with these drugs have yielded mixed results for currently unclear reasons. In this study, we compared the impact of hepatocyte anti-inflammatory (transrepression) versus lipid-lowering (transactivation) properties of PPARα agonism on atherosclerosis in
