Although combinatorial action of transcription factors has been studied throughout the life cycle of organisms [ 2 ] , perhaps the most coherent picture has emerged in the context of developmental processes [ 3 4 ] . Here, a great number of experiments suggest that a major part of the gene regulatory apparatus is organized in the form of separable cis- regulatory modules [ 3 ] . A given module defines specific aspects of the spatio-temporal pattern of gene expression by the combinatorial action of multiple transcription factors which together define the rate of transcription.
The effects of specific RXR ligands on the CAR/RXR heterodimer have not been characterized, although high concentrations of both 9-cis-RA and all-trans retinoic acid have been reported to block PB induction of the CAR targets CYP2B1 and CYP2B2 in primary rat hepatocytes [ 17 ] . In addition, a recent report suggests that both compounds decrease TCPOBOP-dependent CAR transactivation [ 18 ] . In both cases, these effects were primarily attributed to sequestration of limiting amounts of RXR into ligand-dependent homodimers or heterodimers with other receptors.
As expected, 9-cis-RA stimulated coactivator binding to RXR alone, and the basal interaction of CAR with SRC-3 was enhanced by TCPOBOP and decreased by androstanol (Fig.
Initial functional results suggested that transactivation by CAR/RXR heterodimers is not affected by RXR ligands, including 9-cis-RA or synthetic rexinoids, indicating that CAR is a non-permissive RXR partner.
Similarly, the inhibitory effect of the inverse agonist ligand androstanol on coactivator recruitment is blocked by 9-cis-RA.
