    Nuclear receptor corepressor (NCoR) was demonstrated to interact strongly with peroxisome proliferator-activated receptor alpha (PPARalpha), and PPARalpha ligands suppressed this interaction. In contrast to the interaction of PPARalpha with the coactivator protein, p300, association of the receptor with NCoR did not require any part of the PPARalpha ligand binding domain. NCoR was found to suppress PPARalpha-dependent transcriptional activation in the context of a PPARalpha.retinoid X receptor alpha (RXRalpha) heterodimeric complex bound to a peroxisome proliferator-responsive element in human embryonic kidney 293 cells. This repression was reversed agonists of either receptor demonstrating a functional interaction between NCoR and PPARalpha.RXRalpha heterodimeric complexes in mammalian cells. NCoR appears to influence PPARalpha signaling pathways and, therefore, may modulate tissue responsiveness to peroxisome proliferators.
