LXR-dependent gene expression in mouse bone marrow derived macrophages

ABSTRACT: Bone marrow derived macrophages were isolated from C57BL/6J (LXR positive) and LXRalpha +LXRbeta double knockout mice (DKO) that had been treated with vehicle, Kado2-lipid A (KLA, and inflammatory stimulus), acetylated LDL (AcLDL, a mimic of pro-atherogenic lipoprotein particles) and GW3965 (GW, a synthetic LXR agonist) for 17 hours. Following treatment RNA was isolated and RNA-Seq was performed.

RNA-seq of primary human CD4+ T cells treated with the LXR agonist GW3965, with and without TCR stimulation

Project description:We used RNA-sequencing to determine the transcriptional response to liver X receptor (LXR) activation in primary human CD4+ T cells, both at rest and under activation conditions. CD4+ T cells were isolated from 3 healthy donors and treated with the synthetic LXR agonist GW3965 (GW) for 24 hours. Gene expression was compared to control samples (CTRL) treated with the LXR antagonist GSK1440233. To activate the T cell antigen receptor (TCR), cells were pre-treated with CTRL/GW alone for 6 hours then transferred to plates containing anti-CD3 and anti-CD28 for a further 18 hours.

Genome-wide analysis of GW3965-responsive genes in 4 different breast cancer cell lines, MCF-7, T-47D, SK-BR-3, and MDA-MB-231

Project description:Analysis of differentially expressed genes in response to the LXR agonist GW3965 in the MCF-7, T-47D, SK-BR-3, and MDA-MB-231 breast cancer cell lines. It was previously reported that GW3965 has antiproliferative effects on these 4 different breast cancer cell lines. In the present study, we additionally determine the effects of the LXR ligand on breast cancer cells and determine their mechanism of action in reducing cell proliferation. Total RNA obtained from 4 different breast cancer cell lines (MCF-7, T-47D, SK-BR-3, MDA-MB-231) grown in culture treated with ethanol (control) or GW3965 (GW-treated, experimental) for 48 hours. Triplicates were performed.

NHP Liver treated with Vehicle or LXR Ligand

Project description:The LXR-regulated E3 ubiquitin ligase IDOL controls LDLR receptor stability independent of SREBP and PCSK9, but its relevance to plasma lipid levels is unknown. Here we demonstrate that the effects of the LXR–IDOL axis are both tissue- and species-specific. In mice, LXR agonist induces Idol expression in peripheral tissues but not in liver, and does not change plasma LDL levels. Accordingly, Idol-deficient mice exhibit elevated LDLR protein levels in peripheral tissues but not in the liver and have minimal change in plasma LDL levels. By contrast, LXR activation in cynomolgus monkeys induces hepatic IDOL expression, reduces LDLR protein, and raises plasma LDL levels. Knockdown of IDOL in monkeys with an antisense oligonucleotide blunts the effect of LXR agonist on LDL levels. These results implicate IDOL as a modulator of plasma lipid levels in primates and support further investigation into IDOL inhibition as a strategy for LDL lowering in humans.

Bulk RNA-seq of intestinal organoids upon treatment with LXR agonist GW3965

Project description:Liver X Receptor (LXR) activation in intestinal epithelial organoids promotes their growth in vitro. To investigate the downstream effect of LXR activation in intestinal epithelial cells and identify potential pathways driving regeneration, we carried out an unbiased transcriptomic analysis of intestinal epithelial organoids stimulated with the LXR agonist GW3965. In detail, wild type small intestinal crypts were seeded in vitro and stimulated with vehicle (DMSO) or GW3965. After six hours, closing crypts (organoids) were collected for RNA extraction and were analyzed by RNA sequencing.

Transcription profiling of mouse LXRalpha null, LXRbeta null mutants reveals liver X receptor beta is the dominant LXR subtype in skeletal muscle

Project description:Liver X receptors (LXRs) are important regulators of cholesterol, lipid and glucose metabolism and have been extensively studied in liver, macrophages and adipose tissue. However, their role in skeletal muscle is not yet fully elucidated and the functional role of each of the LXRalpha (NR1H3) and LXRbeta (NR1H2) subtypes in skeletal muscle is at present unknown. To study the importance of each of the receptor subtypes, myotube cultures derived from wild type (WT), LXRalpha and LXRbeta knockout (KO) mice were established. The present study shows that treatment with the unselective LXR agonist T0901317 increased mRNA levels of LXR target genes such as sterol regulatory element-binding transcription factor 1 (SREBF1), fatty acid synthase (FASN), stearoyl-CoA desaturase 1 (SCD1) and ATP-binding cassette transporter A1 (ABCA1) in myotubes established from WT and LXRalpha KO mice. However, only minor changes in expression level were observed for these genes after treatment with T0901317 in myotubes from LXRbeta KO mice. Gene expression analysis using Affymetrix NuGO Genechip arrays showed that few other genes than the classical, well known LXR target genes were regulated by LXR in skeletal muscle. Furthermore, functional studies using radiolabeled substrates showed that treatment with T0901317 increased lipogenesis and apoA1 dependent cholesterol efflux, in myotubes from WT and LXRalpha KO mice, but not LXRbeta KO mice. The data suggest that the lipogenic effects of LXRs, as well as the LXR-stimulated cholesterol efflux, are mainly mediated by LXRbeta in skeletal muscle.

Transcriptional effects of LXR nuclear receptors on GM-CSF-derived macrophages

Project description:Analysis of the role of LXR transcriptions factors on the transcriptional signature of human GM-CSF-dependent monocyte-derived macrophages. Methods: Human Peripheral Blood Mononuclear Cells (PBMC) were isolated from buffy coats from donors over a Lymphoprep gradient according to standard procedures. Monocytes were purified from PBMC by magnetic cell sorting using anti-CD14 microbeads (>95% CD14+ cells). Monocytes from three independent donors (0.5 x 106 cells/ml, >95% CD14+ cells) were treated with LXR agonist GW3965 (1 uM, Tocris), LXR antagonist GSK2033 (1 uM, Tocris), GW3965 and GSK2033, or dimethyl sulfoxide (DMSO) as vehicle. In the dual condition, the antagonist was added 1-hour prior to agonist treatment. Then, monocytes were cultured in RPMI 1640 supplemented with 10% fetal bovine serum (FBS) at 37°C in a humidified atmosphere with 5% CO2 and 21% O2 for 7 days in the presence of 1000 U/ml GM-CSF, with cytokine addition every two days.
