Lipid Receptor S1P(1) Activation Scheme Concluded from Microsecond All-Atom Molecular Dynamics Simulations

Sphingosine 1-phosphate (S1P) is a lysophospholipid mediator which activates G protein-coupled sphingosine 1-phosphate receptors and thus evokes a variety of cell and tissue responses including lymphocyte trafficking, endothelial development, integrity, an ...

Binding of Lassa virus perturbs extracellular matrix-induced signal transduction via dystroglycan

Françoise Gisou van der Goot Grunberg, Marie-Laurence Moraz, Stefan Kunz, Christelle Pythoud

The arenavirus Lassa virus (LASV) causes a severe haemorrhagic fever with high mortality in man. The cellular receptor for LASV is dystroglycan (DG). DG is a ubiquitous receptor for extracellular matrix (ECM) proteins, which cooperates with beta 1 integrin ...

The Corepressor NCoR1 Antagonizes PGC-1α and Estrogen-Related Receptor α in the Regulation of Skeletal Muscle Function and Oxidative Metabolism

Johan Auwerx

Skeletal muscle exhibits a high plasticity and accordingly can quickly adapt to different physiological and pathological stimuli by changing its phenotype largely through diverse epigenetic mechanisms. The nuclear receptor corepressor 1 (NCoR1) has the abi ...

Regulation of circadian behaviour and metabolism by REV-ERB-α and REV-ERB-β

Johan Auwerx, Xuan Zhao

The circadian clock acts at the genomic level to coordinate internal behavioural and physiological rhythms via the CLOCK-BMAL1 transcriptional heterodimer. Although the nuclear receptors REV-ERB-α and REV-ERB-β have been proposed to form an accessory feedb ...

Lowering bile acid pool size with a synthetic farnesoid X receptor (FXR) agonist induces obesity and diabetes through reduced energy expenditure

Johan Auwerx, Kristina Schoonjans, Chikage Mataki

We evaluated the metabolic impact of farnesoid X receptor (FXR) activation by administering a synthetic FXR agonist (GW4064) to mice in which obesity was induced by a high fat diet. Administration of GW4064 accentuated body weight gain and glucose intolera ...

Two distinct mechanisms underlie progesterone-induced proliferation in the mammary gland

Cathrin Brisken, Ayyakkannu Ayyanan, Marian Caikovski

The mouse mammary gland develops postnatally under the control of female reproductive hormones. Estrogens and progesterone trigger morphogenesis by poorly understood mechanisms acting on a subset of mammary epithelial cells (MECs) that express their cognat ...

Raised hepatic bile acid concentrations during pregnancy in mice are associated with reduced farnesoid X receptor function

Kristina Schoonjans

Pregnancy alters bile acid homeostasis and can unmask cholestatic disease in genetically predisposed but otherwise asymptomatic individuals. In this report, we show that normal pregnant mice have raised hepatic bile acid levels in the presence of procholes ...

DisSIRTing on LXR and cholesterol metabolism

Johan Auwerx

The NAD-dependent deacetylase SIRT1 regulates lipid and carbohydrate metabolism and has been shown to extend life span in several species. In a recent issue of Molecular Cell, Li et al. (2007) demonstrate that SIRT1 deacetylates and activates the nuclear r ...

Systematic gene expression mapping clusters nuclear receptors according to their function in the brain

Johan Auwerx

Nuclear receptors (NRs) compose a large family of transcription factors that operate at the interface between genes and environment, acting as sensors and effectors that translate endocrine and metabolic cues into well-defined gene expression programs. We ...

Transcriptional coregulators in the control of energy homeostasis

Johan Auwerx

Metabolic programs controlling energy homeostasis are governed at the transcriptional level by the integrated action of several transcription factors. Among these, nuclear receptors including peroxisome proliferator-activated receptors, estrogen-related re ...
