Peroxisome proliferator-activated receptor alpha (PPAR-alpha), also known as NR1C1 (nuclear receptor subfamily 1, group C, member 1), is a nuclear receptor protein that in humans is encoded by the PPARA gene.^[1]

[edit] Function

PPAR-alpha is a transcription factor and a major regulator of lipid metabolism in the liver. PPAR-alpha is activated under nutrient-deficient conditions and is necessary for the process of ketogenesis, a key adaptive response to prolonged fasting ^[2]. Activation of PPAR-alpha promotes uptake, utilization, and catabolism of fatty acids by upregulation of genes involved in fatty acid transport and peroxisomal and mitochondrial fatty acid β-oxidation. PPAR-alpha is primarily activated through ligand binding. Synthetic ligands include the fibrate drugs, which are used to treat hyperlipidemia. An endogenous ligand has been identified as the phosphatidylcholine species 1-palmitoyl-2-oleoyl-sn-glycerol-3-phosphocholine ^[3]. Endogenous activation of PPAR-alpha is dependent on the presence of fatty acid synthase.
