Peroxisome proliferator-activated receptor in lipid metabolism

Peroxisome proliferator-activated receptors (PPAR) are a group of transcription factors belonging to the nuclear receptor superfamily. PPAR can be activated by fatty acid and peroxisome proliferators. Some studies suggested that PPAR act as a regulator of lipid metabolism. In this review, characters of PPAR were described and their significant effects on regulation of lipid metabolism were discussed.
