Peroxisome Proliferator-Activated Receptor Alpha (PPAR-Alpha)
Living reference work entry
The first peroxisome proliferator-activated receptor or PPAR was discovered as hormone receptor that was activated by rodent hepatocarcinogens that induced peroxisome proliferation (Issemann and Green 1990). PPARs are now known as a group of transcription factors that are able to induce transcription of genes that contain PPAR responsive elements (PPREs). The PPAR family of transcription factors consist of PPARα, β of δ (or nuclear receptor subfamily 1, group C, member 2 (NR1C2)), and γ (or nuclear receptor subfamily 1, group C, member 3 NR1C3). Here the focus is on PPARα that, in humans, is mainly expressed in tissue with high fatty acid oxidation like liver, muscle, heart, and kidney though also many other tissues do show expression of this family member. PPARα is thought to be a master regulator of lipid metabolism. It does so by...
