However, much less is known about the role of PPARα in human liver.<h4>Methods</h4>Here we set out to study the function of PPARα in human liver via analysis of whole genome gene regulation in human liver slices treated with the PPARα agonist Wy14643.<h4>Results</h4>Quantitative PCR indicated that PPARα is well expressed in human liver and human liver slices and that the classical PPARα targets PLIN2, VLDLR, ANGPTL4, CPT1A and PDK4 are robustly induced by PPARα activation. Transcriptomics analysis indicated that 617 genes were upregulated and 665 genes were downregulated by PPARα activation (q value < 0.05BMC genomicsThe impact of PPARα activation on whole genome gene expression in human precision cut liver slices.PMC4599789IN-CONTROL CVON2012-03Stoopen GJanssen IMJanssen AWBerends FJBetzel BPeijnenburg AAKersten SfalseThe impact of PPARα activation on whole genome gene expression in human precision cut liver slices.<h4>Background</h4>Studies in mice have shown that PPARα is an important regulator of lipid metabolism in liver and key transcription factor involved in the adaptive response to fasting.
