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

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

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 ...

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 ...

The Slc25a47 locus is a novel determinant of hepatic mitochondrial function implicated in liver fibrosis

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Xiaoxu Li, Hao Li, Hadrien Charles Edouard Demagny, Yu Sun, Vera Monica Lemos Da Silva, Francesca Pontanari, Nadia Bresciani

Background & Aims: Transporters of the SLC25 mitochondrial carrier superfamily bridge cytoplasmic and mitochondrial metabolism by channeling metabolites across mitochondrial membranes and are pivotal for metabolic homeostasis. Despite their physiological r ...

Asparagine protects pericentral hepatocytes during acute liver injury

Kristina Schoonjans, Alessia Perino, Hadrien Charles Edouard Demagny, Ece Yildiz, Antoine Jalil, Yu Sun, Francesca Pontanari, Nadia Bresciani, Adrien Faure Garcia

The nonessential amino acid asparagine can only be synthesized de novo by the enzymatic activity of asparagine synthetase (ASNS). While ASNS and asparagine have been implicated in the response to numerous metabolic stressors in cultured cells, the in vivo ...

LRH-1-dependent programming of mitochondrial glutamine processing drives liver cancer

Johan Auwerx, Arnaud Comment, Kristina Schoonjans, Dongryeol Ryu, Norman Lionel Moullan, Emine Can, Xu Wang, Maaike Hélène Oosterveer, Pan Xu, Hadrien Charles Edouard Demagny

Various tumors develop addiction to glutamine to support uncontrolled cell proliferation. Here we identify the nuclear receptor liver receptor homolog 1 (LRH-1) as a key regulator in the process of hepatic tumorigenesis through the coordination of a noncan ...

Impaired SUMOylation of nuclear receptor LRH-1 promotes nonalcoholic fatty liver disease

Kristina Schoonjans, Dongryeol Ryu, Xu Wang, Vera Monica Lemos Da Silva, Maaike Hélène Oosterveer, Pan Xu, Hadrien Charles Edouard Demagny

Hepatic steatosis is caused by metabolic imbalances that could be explained in part by an increase in de novo lipogenesis that results from increased sterol element binding protein 1 (SREBP-1) activity. The nuclear receptor liver receptor homolog 1 (LRH-1) ...

Wars1 downregulation in hepatocytes induces mitochondrial stress and disrupts metabolic homeostasis

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Xiaoxu Li, Giorgia Benegiamo, Hadrien Charles Edouard Demagny, Antoine Jalil, Francesca Pontanari, Adrien Faure Garcia

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 ...

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 ...

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 ...

OXFORD UNIV PRESS2024

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 ...
