The LXRs: a new class of oxysterol receptors

Curr Opin Genet Dev. 1998 Oct;8(5):571-5. doi: 10.1016/s0959-437x(98)80013-0.


The liver X receptors (LXRs) are a family of transcription factors that were first identified as orphan members of the nuclear receptor superfamily. The identification of a specific class of oxidized derivatives of cholesterol as ligands for the LXRs has been crucial to helping understand the function of these receptors in vivo and first suggested their role in the regulation of lipid metabolism. Confirmation of this role has come from the recent analysis of LXR-deficient mice, which has demonstrated the essential function of one of these receptors in the liver as a major sensor of dietary cholesterol.
