Anti-miR-873-5p improves alcohol-related liver disease by enhancing hepatic deacetylation via SIRT1

Kristina Schoonjans, Petar Petrov

Background & Aims: Current therapies for the treatment of alcohol-related liver disease (ALD) have proven largely ineffective. Patients relapse and the disease progresses even after liver transplantation. Altered epigenetic mechanisms are characteristic of ...

A microbial-derived succinylated bile acid to safeguard liver health

Kristina Schoonjans, Alessia Perino, Hadrien Charles Edouard Demagny

In this issue of Cell, Nie and co-authors report that the microbe-derived bile acid (BA) 3-succinylated cholic acid protects against the progression of metabolic dysfunction-associated liver disease. Intriguingly, its protective mechanism does not involve ...

Non-genomic activation of the AKT-mTOR pathway by the mitochondrial stress response in thyroid cancer

Johan Auwerx, Kristina Schoonjans, Dongryeol Ryu

Cancer progression is associated with metabolic reprogramming and causes significant intracellular stress; however, the mechanisms that link cellular stress and growth signalling are not fully understood. Here, we identified a mechanism that couples the mi ...

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

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

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 ...

Emerging functions of the nuclear receptor LRH-1 in liver physiology and pathology

Kristina Schoonjans, Hadrien Charles Edouard Demagny, Yu Sun

Nuclear receptors play pleiotropic roles in cell differentiation, development, proliferation, and metabolic processes to govern liver physiology and pathology. The nuclear receptor, liver receptor homolog-1 (LRH-1, NR5A2), originally identified in the live ...

Short Article Hypothalamic bile acid-TGR5 signaling protects from obesity

Kristina Schoonjans, Alessia Perino

Bile acids (BAs) improve metabolism and exert anti-obesity effects through the activation of the Takeda G protein-coupled receptor 5 (TGR5) in peripheral tissues. TGR5 is also found in the brain hypothalamus, but whether hypothalamic BA signaling is implic ...

Pancreatic Sirtuin 3 Deficiency Promotes Hepatic Steatosis by Enhancing 5-Hydroxytryptamine Synthesis in Mice With Diet-Induced Obesity

Johan Auwerx, Kristina Schoonjans

Sirtuin 3 (SIRT3) is a protein deacetylase regulating beta-cell function through inhibiting oxidative stress in obese and diabetic mice, but the detailed mechanism and potential effect of beta-cell-specific SIRT3 on metabolic homeostasis, and its potential ...

Dietary Fiber Is Essential to Maintain Intestinal Size, L-Cell Secretion, and Intestinal Integrity in Mice

Kristina Schoonjans

Dietary fiber has been linked to improved gut health, yet the mechanisms behind this association remain poorly understood. One proposed mechanism is through its influence on the secretion of gut hormones, including glucagon-like peptide-1 (GLP-1) and gluca ...

Molecular physiology of bile acid signaling in health, disease, and aging

Kristina Schoonjans, Alessia Perino, Hadrien Charles Edouard Demagny, Laura Alejandra Velazquez Villegas

Over the last two decades, bile acids (BAs) have become established as important signaling molecules that enable fine-tuned inter-tissue communication from the liver, their site of production, over the intestine, where they are modified by the gut microbio ...

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

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

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 ...
