BACKGROUND
Peroxisome proliferator-activated receptors （PPARs） are nuclear hormone
receptors that can be activated by a variety of compounds including fibratus,
thiazolidinediones, prostaglandins and fatty acids. Three PPAR subtypes,
designated PPARα, PPARβ （also designated PPARδ） and PPARγ, have been
described. PPARs promote transcription by forming heterodimers with members
of the retinoid X receptor （RXR） family of steroid receptors and binding
to specific DNA motifs termed PPAR-response elements （PPREs）. PPARα is
abundant in primary hepatocytes where it regulates the expression of proteins
involved in fatty acid metabolism. PPARβ is the most widely distributed
subtype and is often expressed at high levels. PPARγ is predominantly
seen in adipose tissue where it plays a critical role in regulating adipocyte
differentiation. Interestingly, both the orphan nuclear hormone receptor
LXRα and thyroid receptor （TR） have been shown to act as antagonists of
PPARα/RXRα binding to PPREs.
