LRH-1-dependent glucose sensing determines intermediary metabolism in liver

Johan Auwerx, Kristina Schoonjans, Norman Lionel Moullan, Chikage Mataki, Hiroyasu Yamamoto, Taoufiq Harach, Maaike Hélène Oosterveer

Liver receptor homolog 1 (LRH-1), an established regulator of cholesterol and bile acid homeostasis, has recently emerged as a potential drug target for liver disease. Although LRH-1 activation may protect the liver against diet-induced steatosis and insul ...

Mathematical Modeling of Brain Energy Metabolism, Measured with PET and MRS in Rodents

Bernard Lanz

Positron emission tomography (PET) and nuclear magnetic resonance spectroscopy (MRS) are two biomedical measurement techniques developed in the end of the XXth century, which drastically improved the amount of accessible information available in vivo. PET ...

Restoration of direct pathway glycogen synthesis flux in the STZ-diabetes rat model by insulin administration

Ana Francisca Leal Silva Soares

Type 1 diabetes subjects are characterized by impaired direct pathway synthesis of hepatic glycogen that is unresponsive to insulin therapy. Since it is not known whether this is an irreversible defect of insulin-dependent diabetes, direct and indirect pat ...

Adipocyte NCoR Knockout Decreases PPARγ Phosphorylation and Enhances PPARγ Activity and Insulin Sensitivity

Johan Auwerx, Hiroyasu Yamamoto

Insulin resistance, tissue inflammation, and adipose tissue dysfunction are features of obesity and Type 2 diabetes. We generated adipocyte-specific Nuclear Receptor Corepressor (NCoR) knockout (AKO) mice to investigate the function of NCoR in adipocyte bi ...

Lowering bile acid pool size with a synthetic farnesoid X receptor (FXR) agonist induces obesity and diabetes through reduced energy expenditure

Johan Auwerx, Kristina Schoonjans, Chikage Mataki

We evaluated the metabolic impact of farnesoid X receptor (FXR) activation by administering a synthetic FXR agonist (GW4064) to mice in which obesity was induced by a high fat diet. Administration of GW4064 accentuated body weight gain and glucose intolera ...

Two mutations in human BICC1 resulting in Wnt pathway hyperactivity associated with cystic renal dysplasia

Daniel Constam, Marine Marie Kraus, Anne Grapin-Botton

Bicaudal C homologue 1 (Bicc1) knockout in mice causes polycystic kidney disease and pancreas development defects, including a reduction in insulin-producing β-cells and ensuing diabetes. We therefore screened 137 patients with renal abnormalities or assoc ...

Mitochondrial Matrix Calcium Is an Activating Signal for Hormone Secretion

Kristina Schoonjans, Andreas Wiederkehr, Chikage Mataki

Mitochondrial Ca2+ signals have been proposed to accelerate oxidative metabolism and ATP production to match Ca2+-activated energy-consuming processes. Efforts to understand the signaling role of mitochondrial Ca2+ have been hampered by the inability to ma ...

JewelPUMP (TM) by Debiotech S.A.: Insulin Temperature Measurement Study

Adrien De Muralt

For type 1 Diabetes, insulin injection therapy is the most used treatment today, and insulin pumps are surely the most accurate therapeutic strategy. The insulin use temperature has to not exceed 37°C to prevent unwanted degradation and loss of function. T ...

SRT1720 improves survival and healthspan of obese mice

Johan Auwerx, Carlos Canto Alvarez

Sirt1 is an NAD1-dependent deacetylase that extends lifespan in lower organisms and improves metabolism and delays the onset of age-related diseases in mammals. Here we show that SRT1720, a synthetic compound that was identified for its ability to activate ...

In Vivo Evidence for Lactate as a Neuronal Energy Source

Pierre Magistretti, Renaud Jolivet

Cerebral energy metabolism is a highly compartmentalized and complex process in which transcellular trafficking of metabolites plays a pivotal role. Over the past decade, a role for lactate in fueling the energetic requirements of neurons has emerged. Furt ...
