ABSTRACT: Background and aim
Peroxisome proliferator-activated receptor alpha (PPARα) is a molecular target of various fibrate drugs clinically used to lower serum lipids. However, the tissue-specific functions of PPARα remain to be elucidated. This study aimed to explore the tissue-specific functions of PPARα in response to Wy-14643.Methods
A hepatocyte-specific Ppara knockout mouse line was used to explore the impact of hepatic PPARα activity on the systemic response to treatment with the potent PPARα agonist Wy-14643.Results
Wy-14643 mainly activated hepatic PPARα and regulated the expression of PPARα target genes in liver. Hepatic Ppara disruption abolished the triglyceride lowering effects of Wy-14643, prevented agonist-induced hypophagia, and ablated PPARα target gene response in the liver.Conclusions
These findings indicate that Wy-14643 treatment mainly activates hepatic PPARα, and the hypolipidemic and hypophagic effects of Wy-14643 are dependent on PPARα activation within hepatocytes.
