The Gene-Regulatory Footprint of Aging Highlights Conserved Central Regulators

Johan Auwerx, Richardus Houtkooper, Maroun Bou Sleiman, Xu Wang, Pooja Jha

Many genes and pathways have been linked to aging, yet our understanding of underlying molecular mechanisms is still lacking. Here, we measure changes in the transcriptome, histone modifications, and DNA methylome in three metabolic tissues of adult and ag ...

MicroRNA-204-5p modulates mitochondrial biogenesis in C2C12 myotubes and associates with oxidative capacity in humans

Xu Wang

Using an unbiased high-throughput microRNA (miRNA)-silencing screen combined with functional readouts for mitochondrial oxidative capacity in C2C12 myocytes, we previously identified 19 miRNAs as putative regulators of skeletal muscle mitochondrial metabol ...

MicroRNA-382 silencing induces a mitonuclear protein imbalance and activates the mitochondrial unfolded protein response in muscle cells

Johan Auwerx, Pénélope Andreux, Xu Wang, Norman Lionel Moullan

Proper mitochondrial function plays a central role in cellular metabolism. Various diseases as well as aging are associated with diminished mitochondrial function. Previously, we identified 19 miRNAs putatively involved in the regulation of mitochondrial m ...

Plasma Membrane-bound G Protein-coupled Bile Acid Receptor Attenuates Liver Ischemia/Reperfusion Injury Via the Inhibition of Toll-like Receptor 4 Signaling in Mice

Johan Auwerx, Kristina Schoonjans, Xu Wang

The plasma membrane-bound G protein-coupled bile acid receptor (TGR5) displays varied levels of expression in different tissues. TGR5-induced liver protection has been demonstrated during several liver diseases, except during ischemia/reperfusion injury (I ...

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) ...

An unbiased silencing screen in muscle cells identifies miR-320a, miR-150, miR-196b, and miR-34c as regulators of skeletal muscle mitochondria! metabolism

Johan Auwerx, Pénélope Andreux, Xu Wang

Objective: Strategies improving skeletal muscle mitochondrial capacity are commonly paralleled by improvements in (metabolic) health. We and others previously identified microRNAs regulating mitochondrial oxidative capacity, but data in skeletal muscle are ...

Systems Phytohormone Responses to Mitochondrial Proteotoxic Stress

Johan Auwerx, Xu Wang

Mitochondrial function is controlled by two separate genomes. This feature makes mitochondria prone to proteotoxic stress when a stoichiometric imbalance occurs in the protein complexes that perform oxidative phosphorylation, which consist of both nucleara ...

Enhanced Respiratory Chain Supercomplex Formation in Response to Exercise in Human Skeletal Muscle

Johan Auwerx, Carlos Canto Alvarez, Xu Wang, Pooja Jha, Chiara Greggio

Mitochondrial dysfunction is a hallmark of multiple metabolic complications. Physical activity is known to increase mitochondrial content in skeletal muscle, counteracting age-related decline in muscle function and protecting against metabolic and cardiova ...

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 ...
