Liver X Receptor Alpha (LXRα; NR1H3)
Also available in: Mouse
These LXRα Reporter Assay Systems utilize non-human mammalian cells engineered to express human NR1H3 protein, commonly referred to as LXRα.
Liver X Receptor Alpha (LXRα) is a nuclear receptor protein encoded by the NR1H3 gene (nuclear receptor subfamily 1, group H, member 3). The Liver X Receptors (LXRs) were originally identified as orphan members of the nuclear receptor superfamily because their ligands were unknown. Like other receptors in the family, LXRs heterodimerize with Retinoid X Receptors and bind to specific response elements (LXREs) characterized by direct repeats separated by 4 nucleotides.

Kits are offered in different assay formats to accommodate researchers’ needs: 3 x 32, 1 x 96, and 1 x 384 assay formats for screening small numbers of test compounds, as well as custom bulk reagents for HTS applications. Assay systems are all inclusive, providing reporter cells, optimized growth media, media for diluting test compounds, a positive-control agonist, luciferase detection reagent, a white assay plate, a detailed protocol, and a protocol quick guide. All kits are shipped on dry ice.
LXR Reporter Cells are prepared using INDIGO’s proprietary CryoMite™ process. This cryo-preservation method yields high cell viability post-thaw, and provides the convenience of immediately dispensing healthy, division-competent reporter cells into assay plates. There is no need for intermediate spin-and-wash steps, viability determinations, or cell titer adjustments.
The principle application of this LXRα assay product is in the screening of test samples to quantify functional activities, either agonist or antagonist, that they may exert against the human liver x receptor alpha. This kit product is an all-inclusive assay system that includes, in addition to LXR Reporter Cells, two optimized media for use during cell culture and (optionally) in diluting the test samples, a reference agonist, Luciferase Detection Reagent, a cell culture-ready assay plate, and a detailed protocol.

The primary application of INDIGO’s cell-based nuclear receptor assays are to quantitatively assess the bioactivity of a test compound as an agonist (activator) or antagonist (inhibition of an agonist response) of a given receptor. Service assays include a positive control reference compound and ‘vehicle’ control for every experiment. A formal study report and all data files are provided to the client upon completion of the study.

ABSTRACT Chemicals that alter normal function of farnesoid X receptor (FXR) have been shown to affect the homeostasis of bile acids, glucose, and lipids. Several structural classes of environmental chemicals and drugs that modulated FXR transactivation were previously identified by quantitative high-throughput screening (qHTS) of the Tox21 10 K chemical collection. In the present study, we
ABSTRACT Exposure to certain munitions compounds is know to alter physiological functions in test organisms, however little is known about their molecular and cellular effects. Several nuclear receptors are regulated by xenobiotic compounds. These nuclear receptors belong to a class of ligand-activated transcription factors that, when heterodimerized with RXRa and bound to their respective DNA
ABSTRACT The apolipoprotein E (APOE) gene is the most highly associated susceptibility locus for late onset Alzheimer’s Disease (AD), and augmenting the beneficial physiological functions of apoE is a proposed therapeutic strategy. In a high throughput phenotypic screen for small molecules that enhance apoE secretion from human CCF-STTG1 astrocytoma cells, we show the chrysanthemic ester
In vitro toxicology platform provides predictive model of liver toxicity. Aims to reduce the high rates of drug-induced liver damage State College, PA (May 4, 2016) INDIGO Biosciences, the recognized industry leader in nuclear receptor research, has completed development of an in vitro toxicology platform, meeting the demand for predictive liver toxicity models. INDIGO’s in
ABSTRACT Luteolin is a dietary flavonoid with medicinal properties including antioxidant, antimicrobial, anticancer, antiallergic, and anti-inflammatory. However, the effect of luteolin on liver X receptors (LXRs), oxysterol sensors that regulate cholesterol homeostasis, lipogenesis, and inflammation, has yet to be studied. To unveil the potential of luteolin as an LXRα/β modulator, we investigated by real-time RT-PCR
In vitro assessment of human nuclear hormone receptor activity and cytotoxicity of the fame retardant mixture FM 550 and its triarylphosphate and brominated components
ABSTRACT Firemaster®550 (FM 550) is a mixture of brominated and triarylphosphate flame retardants used in polyurethane foam-based products. The primary components are also used in numerous other applications and are thus common household and industrial contaminants. Our previous animal studiessuggested that FM 550 exposure may alter metabolism and cause weight gain. Employing human nuclear receptor
ABSTRACT Omega-3-PUFAs, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), are associated with prevention of various aspects of metabolic syndrome. In the present studies, the effects of oil rich in EPA on gene expression and activation of nuclear receptors was examined and compared with other 3-PUFAs. The EPA-rich oil (EO) altered the expression of FA metabolism genes in THP-1 cells, including stearoyl
Differential Activation of Nuclear Receptors by Perflunoriated Fatty Acid Analogs and Natural Fatty Acids: A Comparison of Human, Mouse, and Rat Peroxisome Proliferator-Activated Receptor Receptor-a, -b, and -c, Liver X Receptor-b, and Retinoid X Receptor-a
ABSTRACT Administration of ammonium salts of perfluorooctanoate (PFOA) to rats results in peroxisome proliferation and benign liver tumors, events associated with activation of the nuclear receptor (NR) peroxisome proliferator-activated receptor-a (PPARa). Due to its fatty acid structure, PFOA may activate other NRs, such as PPARb, PPARg, liver X receptor (LXR), or retinoid X receptor (RXR). In this study, the
