Sirt6 deletion in bone marrow-derived cells increases atherosclerosis - Central role of macrophage scavenger receptor 1

Johan Auwerx, Matthias Alexander Sokrates Stein, Julien Weber, Tasneem Arsiwala

Aims: Sirtuin 6 (Sirt6) is a NAD(+)-dependent deacetylase that plays a key role in DNA repair, inflammation and lipid regulation. Sirt6-null mice show severe metabolic defects and accelerated aging. Macrophage-foam cell formation via scavenger receptors is ...

Inhibiting poly ADP-ribosylation increases fatty acid oxidation and protects against fatty liver disease

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Dongryeol Ryu, Vera Monica Lemos Da Silva, Elena Katsyuba, Jun Yong Kim, Hongbo Zhang, Pooja Jha, Keir Joe Menzies

Background & Aims: To date, no pharmacological therapy has been approved for non-alcoholic fatty liver disease (NAFLD). The aim of the present study was to evaluate the therapeutic potential of poly ADP-ribose polymerase (PARP) inhibitors in mouse models o ...

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

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

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) ...

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

Johan Auwerx, Kristina Schoonjans, Arnaud Comment, Hadrien Charles Edouard Demagny, Dongryeol Ryu, Xu Wang, Emine Can, Norman Lionel Moullan, Pan Xu, Matthias Alexander Sokrates Stein

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 ...

Molecular basis for the regulation of the nuclear receptor LRH-1

Kristina Schoonjans, Matthias Alexander Sokrates Stein

Liver receptor homolog-1 (LRH-1) is a nuclear receptor (NR) with diverse functions in development, differentiation and metabolism and has been extensively studied in the enterohepatic system. While initially described as an orphan NR, recent studies sugges ...

LRH-1 mediates anti-inflammatory and antifungal phenotype of IL-13-activated macrophages through the PPAR gamma ligand synthesis

Kristina Schoonjans, Matthias Alexander Sokrates Stein

Liver receptor homologue-1 (LRH-1) is a nuclear receptor involved in the repression of inflammatory processes in the hepatointestinal tract. Here we report that LRH-1 is expressed in macrophages and induced by the Th2 cytokine IL-13 via a mechanism involvi ...

A SIRT7-Dependent Acetylation Switch of GABPβ1 Controls Mitochondrial Function

Johan Auwerx, Kristina Schoonjans, Alessia Perino, Dongryeol Ryu, Hongbo Zhang, Matthias Alexander Sokrates Stein, Giuseppe Lo Sasso

Mitochondrial activity is controlled by proteins encoded by both nuclear and mitochondrial DNA. Here, we identify Sirt7 as a crucial regulator of mitochondrial homeostasis. Sirt7 deficiency in mice induces multisystemic mitochondrial dysfunction, which is ...

TGR5 reduces macrophage migration through mTOR-induced C/EBP beta differential translation

Kristina Schoonjans, Alessia Perino, Matthias Alexander Sokrates Stein, Mitsunori Nomura, Thijs Pols

The bile acid-responsive G protein-coupled receptor TGR5 is involved in several metabolic processes, and recent studies suggest that TGR5 activation may promote pathways that are protective against diet-induced diabetes. Here, we investigated the role of m ...

SUMOylation-Dependent LRH-1/PROX1 Interaction Promotes Atherosclerosis by Decreasing Hepatic Reverse Cholesterol Transport

Kristina Schoonjans, Alessia Perino, Dongryeol Ryu, Vera Monica Lemos Da Silva, Xu Wang, Chikage Mataki, Pan Xu, Keir Joe Menzies, Matthias Alexander Sokrates Stein, Maaike Hélène Oosterveer

Reverse cholesterol transport (RCT) is an antiatherogenic process in which excessive cholesterol from peripheral tissues is transported to the liver and finally excreted from the body via the bile. The nuclear receptor liver receptor homolog 1 (LRH-1) driv ...
