Previous studies using low and high throughput gene expression analysis have demonstrated that PPAR[alpha] modulates the expression of numerous genes involved in virtually every profile of lipid metabolism, including FFA uptake, mitochondrial and peroxisome fatty acid oxidation (FAO), cytogenesis, and the formation and breakdown of triglycerides and lipid droplets [25].
