Asparagine protects pericentral hepatocytes during acute liver injury

Kristina Schoonjans, Alessia Perino, Hadrien Charles Edouard Demagny, Antoine Jalil, Ece Yildiz, Yu Sun, Nadia Bresciani

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 ...

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

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

Integrative systems analysis identifies genetic and dietary modulators of bile acid homeostasis

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Xiaoxu Li, Giacomo Vincenzo Giorgio Von Alvensleben, Hao Li, Maroun Bou Sleiman, Karim Laurent Gariani, Laura Alejandra Velazquez Villegas, Ludger Jan Elzuë Goeminne

Bile acids (BAs) are complex and incompletely understood enterohepatic-derived hormones that control whole-body metabolism. Here, we profiled postprandial BAs in the liver, feces, and plasma of 360 chowor high-fat-diet-fed BXD male mice and demonstrated th ...

Dissecting the role of the asparagine synthesis in acute liver injury

Yu Sun

Amino acids are some of the main building stones of life used in a variety of biological processes, such as protein synthesis, energy metabolism or even as precursors for hormone synthesis. How-ever, some of them also participate and coordinate certain cel ...

Central anorexigenic actions of bile acids are mediated by TGR5

Kristina Schoonjans, Alessia Perino, Laura Alejandra Velazquez Villegas, Qingyao Huang, Yu Sun, Nadia Bresciani

Bile acids (BAs) are signalling molecules that mediate various cellular responses in both physiological and pathological processes. Several studies report that BAs can be detected in the brain, yet their physiological role in the central nervous system is ...

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 ...
