Protection from Metabolic Dysregulation, Obesity, and Atherosclerosis by Citrus Flavonoids: Activation of Hepatic PGC1α-Mediated Fatty Acid Oxidation

Figure 1

Regulation of gene expression by peroxisome proliferator-activated receptors. The nuclear hormone receptor PPARα induces transcription through formation of a heterodimer with the retinoic X receptor and binding to peroxisome proliferator response elements (most are direct repeats with one intervening nucleotide) in the promoter of genes involved in fatty acid oxidation. PGC1α is an important PPARα coactivator in tissues that undergo extensive oxidative metabolism and induce mitochondrial expansion.
