BioAssay: AID 715944

Agonist activity at human LXR-beta assessed as increase in recruitment of Trap 220/D22 coactivator peptide by TR-FRET assay

The present study reports a novel liver X receptor (LXR) activator, ethyl 2,4,6-trihydroxybenzoate (ETB), isolated from Celtis biondii. Using a reporter gene assay, time-resolved fluorescence resonance energy transfer (TR-FRET), and surface plasmon resonance (SPR) analysis, we showed that ETB directly bound to and stimulated the transcriptional activity of LXR-alpha and LXR-beta. In macrophages, more ..

Description:
Title: Ethyl 2,4,6-trihydroxybenzoate is an agonistic ligand for liver X receptor that induces cholesterol efflux from macrophages without affecting lipid accumulation in HepG2 cells.

Abstract: The present study reports a novel liver X receptor (LXR) activator, ethyl 2,4,6-trihydroxybenzoate (ETB), isolated from Celtis biondii. Using a reporter gene assay, time-resolved fluorescence resonance energy transfer (TR-FRET), and surface plasmon resonance (SPR) analysis, we showed that ETB directly bound to and stimulated the transcriptional activity of LXR-alpha and LXR-beta. In macrophages, hepatocytes, and intestinal cells, ETB suppressed cellular cholesterol accumulation in a dose-dependent manner and induced the transcriptional activation of LXR-alpha/-beta-responsive genes. Notably, ETB did not induce lipogenic gene expression or cellular triglyceride accumulation in hepatocytes. These results suggest that ETB is a dual-LXR modulator that regulates the expression of key genes in cholesterol homeostasis in multiple cells without inducing lipid accumulation in HepG2 cells.
