Oxysterols 39-48 retinoid X receptor alpha Homo sapiens 219-222 18782758-3 2008 The transcription of ABCA1 is regulated by intracellular oxysterol concentration via the nuclear liver X receptor (LXR)/retinoid X receptor (RXR); once synthesized, ABCA1 protein turns over rapidly with a half-life of 1-2 h. Here, we show that the LXRbeta/RXR complex binds directly to ABCA1 on the plasma membrane of macrophages and modulates cholesterol secretion. Oxysterols 57-66 retinoid X receptor alpha Homo sapiens 120-139 18782758-3 2008 The transcription of ABCA1 is regulated by intracellular oxysterol concentration via the nuclear liver X receptor (LXR)/retinoid X receptor (RXR); once synthesized, ABCA1 protein turns over rapidly with a half-life of 1-2 h. Here, we show that the LXRbeta/RXR complex binds directly to ABCA1 on the plasma membrane of macrophages and modulates cholesterol secretion.

Oxysterols 57-66 retinoid X receptor alpha Homo sapiens 256-259 14769039-3 2004 Cholesterol- and oxysterol-mediated up-regulation of ABCA1 transcription includes the binding of the liver X receptor and retinoid X receptor (LXR/RXR) heterodimer to the DR-4 element of the ABCA1 promoter.

Oxysterols 0-9 retinoid X receptor alpha Homo sapiens 29-32 11606068-1 2001 Here we report the induction of gene expression of ABCG4, a member of the ABC transporter subfamily G, from human macrophages by oxysterols and retinoids, agonists of the nuclear receptors LXR and RXR.
