Bile acid 7α-dehydroxylating bacteria accelerate injury-induced mucosal healing in the colon

Kristina Schoonjans, Rizlan Bernier-Latmani, Alessia Perino, Hadrien Charles Edouard Demagny, Eduard Vico Oton, Colin Volet, Antoine Jalil

Host-microbiome communication is frequently perturbed in gut pathologies due to microbiome dysbiosis, leading to altered production of bacterial metabolites. Among these, 7 alpha-dehydroxylated bile acids are notably diminished in inflammatory bowel diseas ...

Protecting liver health with microbial-derived succinylated bile acids

Kristina Schoonjans, Alessia Perino, Hadrien Charles Edouard Demagny

The gut microbiome produces a plethora of metabolites that influence host metabolism. In a recent article published in Cell, Nie and colleagues reveal that 3-succinylated cholic acid, a microbe-derived bile acid, protects against metabolic dysfunction-asso ...

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 ...

Loss of hepatic Sirt7 accelerates diethylnitrosamine (DEN)-induced formation of hepatocellular carcinoma by impairing DNA damage repair

Johan Auwerx, Kristina Schoonjans

The mammalian sirtuin family (SIRT1-SIRT7) has shown diverse biological roles in the regulation and maintenance of genome stability under genotoxic stress. SIRT7, one of the least studied sirtuin, has been demonstrated to be a key factor for DNA damage res ...

Inhibition of SIRT7 overcomes sorafenib acquired resistance by suppressing ERK1/2 phosphorylation via the DDX3X-mediated NLRP3 inflammasome in hepatocellular carcinoma

Johan Auwerx, Kristina Schoonjans, Pan Xu

Aims: Sirtuin 7 (SIRT7) plays an important role in tumor development, and has been characterized as a potent regulator of cellular stress. However, the effect of SIRT7 on sorafenib acquired resistance remains unclear and a possible anti-tumor mechanism bey ...

Wars1 downregulation in hepatocytes induces mitochondrial stress and disrupts metabolic homeostasis

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Xiaoxu Li, Hadrien Charles Edouard Demagny, Antoine Jalil

Several laboratories, including ours, have employed the Slc25a47tm1c(EUCOMM)Hmgu mouse model to investigate the role of SLC25A47, a hepatocyte-specific mitochondrial carrier, in regulating hepatic metabolism and systemic physiology. In this study, we revea ...

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 ...

TGR5 receptors in SF1-expressing neurons of the ventromedial hypothalamus regulate glucose homeostasis

Kristina Schoonjans

Objective: Steroidogenic factor-1 (SF1) neurons of the ventromedial hypothalamus play key roles in the regulation of food intake, body weight and glucose metabolism. The bile acid receptor Takeda G protein-coupled receptor 5 (TGR5) is expressed in the hypo ...

An antibiotic and a microorganism having bile acid 7α-dehydroxylation activity for treating non-infectious diseases

Kristina Schoonjans, Alessia Perino, Antoine Jalil

The present invention relates to one or more antibiotic(s) that disrupt(s) the microbial balance of the gut and a microorganism having bile acid 7α-dehydroxylation activity for use in the treatment of a non-infectious disease in a subject. ...
