Nuclear receptors FXR and SHP regulate protein N-glycan modifications in the liver

Kristina Schoonjans

Nuclear receptors farnesoid X receptor (FXR) and small heterodimer partner (SHP) are key regulators of metabolism. Here, we report a previously unknown function for the hepatic FXR-SHP axis in controlling protein N-linked glycosylation. Transcriptome analy ...

Bile acids drive colonic secretion of glucagon-like-peptide 1 and peptide-YY in rodents

Kristina Schoonjans

A large number of glucagon-like-peptide-1(GLP-1)- and peptide-YY (PYY)-producing L cells are located in the colon, but little is known about their contribution to whole body metabolism. Since bile acids (BAs) increase GLP-1 and PYY release, and since BAs s ...

Compound 18 Improves Glucose Tolerance in a Hepatocyte TGR5-dependent Manner in Mice

Kristina Schoonjans, Adriano Maida

The bile acid receptor, TGR5, is a key regulator of glucose homeostasis, but the mechanisms by which TGR5 signaling improves glucose regulation are incompletely defined. In particular, TGR5 has an increasingly appreciated role in liver physiology and patho ...

Bile acids deoxycholic acid and ursodeoxycholic acid differentially regulate human beta-defensin-1 and-2 secretion by colonic epithelial cells

Kristina Schoonjans, Alessia Perino

Bile acids and epithelial-derived human beta-defensins (H beta Ds) are known to be important factors in the regulation of colonic mucosal barrier function and inflammation. We hypothesized that bile acids regulate colonic H beta D expression and aimed to t ...

Mechano-modulatory synthetic niches for liver organoid derivation

Matthias Lütolf, Kristina Schoonjans, Saba Rezakhani, Giovanni Sorrentino, Ece Yildiz

The recent demonstration that primary cells from the liver can be expanded in vitro as organoids holds enormous promise for regenerative medicine and disease modelling. The use of three-dimensional (3D) cultures based on ill-defined and potentially immunog ...

Bile Acids Signal via TGR5 to Activate Intestinal Stem Cells and Epithelial Regeneration

Gaby El Alam, Kristina Schoonjans, Maroun Bou Sleiman, Alessia Perino, Giovanni Sorrentino, Ece Yildiz

BACKGROUND & AIMS: Renewal and patterning of the intestinal epithelium is coordinated by intestinal stem cells (ISCs); dietary and metabolic factors provide signals to the niche that control ISC activity. Bile acids (BAs), metabolites in the gut, signal nu ...

NCoR1 Is a Conserved Physiological Modulator of Muscle Mass and Oxidative Function

Johan Auwerx, Kristina Schoonjans, Carlos Canto Alvarez, Laurent Mouchiroud, Evan Graehl Williams, Hiroyasu Yamamoto

Transcriptional coregulators control the activity of many transcription factors and are thought to have wide-ranging effects on gene expression patterns. We show here that muscle-specific loss of nuclear receptor corepressor 1 (NCoR1) in mice leads to enha ...

L-Cell Differentiation Is Induced by Bile Acids Through GPBAR1 and Paracrine GLP-1 and Serotonin Signaling

Kristina Schoonjans, Giovanni Sorrentino

Glucagon-like peptide 1 (GLP-1) mimetics are effective drugs for treatment of type 2 diabetes, and there is consequently extensive interest in increasing endogenous GLP-1 secretion and L-cell abundance. Here we identify G-protein-coupled bile acid receptor ...

Probing the Binding Site of Bile Acids in TGR5

Johan Auwerx, Kristina Schoonjans, Thijs Pols

TGR5 is a G-protein-coupled receptor (GPCR) mediating cellular responses to bile acids (BAs). Although some efforts have been devoted to generate homology models of TGR5 and draw structure-activity relationships of BAs, none of these studies has hitherto d ...

V-ATPase/TORC1-mediated ATFS-1 translation directs mitochondrial UPR activation in C. elegans

Johan Auwerx, Kristina Schoonjans, Felix Naef, Xiaoxu Li, Yang Li, Hao Li, Jia Liu, Yan Liu, Wen Gao, Amélia Lalou, Nagammal Neelagandan

To adapt mitochondrial function to the ever-changing intra- and extracellular environment, multiple mitochondrial stress response (MSR) pathways, including the mitochondrial unfolded protein response (UPRmt), have evolved. However, how the mitochondrial st ...

Bile acid-FXR alpha pathways regulate male sexual maturation in mice

Kristina Schoonjans

The bile acid receptor Farnesol-X-Receptor alpha (FRX alpha) is a member of the nuclear receptor superfamily. FRX alpha is expressed in the interstitial compartment of the adult testes, which contain the Leydig cells. In adult, short term treatment (12 hou ...

Pharmacological Inhibition of Poly(ADP-Ribose) Polymerases Improves Fitness and Mitochondrial Function in Skeletal Muscle

Johan Auwerx, Kristina Schoonjans, Carlos Canto Alvarez, Laurent Mouchiroud, Evan Graehl Williams, Norman Lionel Moullan, Hongbo Zhang, Keir Joe Menzies, Eija Riitta Pirinen, Laia Morato Fornaguera

We previously demonstrated that the deletion of the poly(ADP-ribose) polymerase (Parp)-1 gene in mice enhances oxidative metabolism, thereby protecting against diet-induced obesity. However, the therapeutic use of PARP inhibitors to enhance mitochondrial f ...

Emerging actions of the nuclear receptor LRH-1 in the gut

Johan Auwerx, Kristina Schoonjans, Pablo Jose Fernandez Marcos

Liver receptor homolog-1 (NR5A2) is a nuclear receptor originally identified in the liver and mostly known for its regulatory role in cholesterol and bile acid homeostasis. More recently, liver receptor homolog-1 has emerged as a key regulator of intestina ...

SIRT2 Deficiency Modulates Macrophage Polarization and Susceptibility to Experimental Colitis

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Alessandra Piersigilli, Adrienne Joëlle Laurence Mottis, Hiroyasu Yamamoto, Giuseppe Lo Sasso, Keir Joe Menzies

Background: SIRT2 belongs to a highly conserved family of NAD(+)-dependent deacylases, consisting of seven members (SIRT1-SIRT7), which vary in subcellular localizations and have substrates ranging from histones to transcription factors and enzymes. Recent ...
