BioAssay: AID 727609

Induction of recruitment of D20 peptide to LXRbeta (unknown origin) by TR-FRET LXR-alpha co-activator assay

We investigated the effect of cineole on the expression of genes related to reverse cholesterol transport and hepatic fatty acid metabolism. Cineole, a small aroma compound in teas and herbs, significantly stimulated the transactivation of liver X receptor modulator (LXR)-alpha and LXR-beta. The mRNA and protein expression of LXRs and their target genes, including ABCA1 and ABCG1, was more ..

Title: Induction of ABCA1 and ABCG1 expression by the liver X receptor modulator cineole in macrophages.

Abstract: We investigated the effect of cineole on the expression of genes related to reverse cholesterol transport and hepatic fatty acid metabolism. Cineole, a small aroma compound in teas and herbs, significantly stimulated the transactivation of liver X receptor modulator (LXR)-alpha and LXR-beta. The mRNA and protein expression of LXRs and their target genes, including ABCA1 and ABCG1, was significantly increased in macrophages stimulated with cineole. This led to the subsequent removal of cholesterol from the cells. Interestingly, cineole showed tissue-selective LXR induction: hepatocytes stimulated with cineole showed significantly reduced expression of LXR-alpha and LXR-alpha-responsive genes, including FAS and SCD-1 (P <0.05). Accordingly, hepatocytes treated with cineole displayed reduced cellular lipid accumulation compared with control cells, as assessed by Oil Red O lipid staining and cholesterol quantification. These results suggest that cineole is a selective LXR modulator that regulates the expression of key genes in reverse cholesterol transport in macrophages without inducing lipogenesis in hepatocytes. This selective LXR modulator may have practical implications for the development of hypocholesterolemic or anti-atherosclerotic agents and also suggests.
