Evidence for a neuromuscular circuit involving hypothalamic interleukin-6 in the control of skeletal muscle metabolism

Vera Monica Lemos Da Silva, Eduardo Rochete Ropelle, Ludger Jan Elzuë Goeminne, Barbara Moreira Crisol

Hypothalamic interleukin-6 (IL6) exerts a broad metabolic control. Here, we demonstrated that IL6 activates the ERK1/2 pathway in the ventromedial hypothalamus (VMH), stimulating AMPK/ACC signaling and fatty acid oxidation in mouse skeletal muscle. Bioinfo ...

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

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

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 ...

The RNA-Binding Protein PUM2 Impairs Mitochondrial Dynamics and Mitophagy During Aging

Bernard Schneider, Graham Knott, Kristina Schoonjans, Johan Auwerx, Adrienne Joëlle Laurence Mottis, Vera Monica Lemos Da Silva, Hao Li, Vincenzo Sorrentino, Davide D'Amico, Mario Romani, Francesca Potenza

Little information is available about how post-transcriptional mechanisms regulate the aging process. Here, we show that the RNA-binding protein Pumilio2 (PUM2), which is a translation repressor, is induced upon aging and acts as a negative regulator of li ...

A new class of protein biomarkers based on subcellular distribution: application to a mouse liver cancer model

Ruedi Aebersold, Kristina Schoonjans, Evan Graehl Williams, Pan Xu, Amir Banaei Esfahani, Vera Monica Lemos Da Silva, Chen Li

To-date, most proteomic studies aimed at discovering tissue-based cancer biomarkers have compared the quantity of selected proteins between case and control groups. However, proteins generally function in association with other proteins to form modules loc ...

TGR5 signalling promotes mitochondrial fission and beige remodelling of white adipose tissue

Kristina Schoonjans, Mitsunori Nomura, Thijs Pols, Alessia Perino, Vera Monica Lemos Da Silva, Laura Alejandra Velazquez Villegas, Marika Olga Zietak

The NAD(+)-dependent deacetylase SIRT2 attenuates oxidative stress and mitochondrial dysfunction and improves insulin sensitivity in hepatocytes

Vera Monica Lemos Da Silva

Insulin resistance is a major predictor of the development of metabolic disorders. Sirtuins (SIRTs) have emerged as potential targets that can be manipulated to counteract age-related diseases, including type 2 diabetes. SIRT2 has been recently shown to ex ...

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

Elena Katsyuba, Matthias Alexander Sokrates Stein, Kristina Schoonjans, Johan Auwerx, Dongryeol Ryu, Hongbo Zhang, Keir Joe Menzies, Alessia Perino, Karim Laurent Gariani, Vera Monica Lemos Da Silva, Pooja Jha, Jun Yong Kim

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

Matthias Alexander Sokrates Stein, Kristina Schoonjans, Dongryeol Ryu, Maaike Hélène Oosterveer, Pan Xu, Xu Wang, Vera Monica Lemos Da Silva, 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) ...

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

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

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 ...
