Towards Elucidating the Mechanism of Action of Biguanides

Diabetes type 2 patients are insensitive to insulin, a condition that leads to reduced glucose uptake by cells and, subsequently, to high concentration of glucose in the blood. For 60 years, biguanides have been one of the few effective therapeutics in red ...

Sexual dimorphism in hepatic lipids is associated with the evolution of metabolic status in mice

Rolf Gruetter, Hongxia Lei, Jonathan Paz Montoya, Marc Moniatte, Ana Francisca Leal Silva Soares

Ectopic lipid accumulation in the liver is implicated in metabolic disease in an age- and sex-dependent manner. The role of hepatic lipids has been well established within the scope of metabolic insults in mice, but has been insufficiently characterized un ...

SIRT1 Gain of Function Does Not Mimic or Enhance the Adaptations to Intermittent Fasting

Carlos Canto Alvarez, Patrick Descombes, Sylviane Métairon

Caloric restriction (CR) has been shown to prevent the onset of insulin resistance and to delay age-related physiological decline in mammalian organisms. SIRT1, a NAD(+) -dependent deacetylase enzyme, has been suggested to mediate the adaptive responses to ...

Bile Acids Trigger GLP-1 Release Predominantly by Accessing Basolaterally Located G Protein-Coupled Bile Acid Receptors

Kristina Schoonjans

Bile acids are well-recognized stimuli of glucagon-like peptide-1 (GLP-1) secretion. This action has been attributed to activation of the G protein-coupled bile acid receptor GPBAR1 (TGR5), although other potential bile acid sensors include the nuclear far ...

Multilayered genetic and omics dissection of mitochondrial activity in a mouse reference population

Johan Auwerx, Evan Graehl Williams, Adrienne Joëlle Laurence Mottis, Virginija Jovaisaite, Ruedi Aebersold, Sébastien Dubuis

The manner by which genotype and environment affect complex phenotypes is one of the fundamental questions in biology. In this study, we quantified the transcriptome--a subset of the metabolome--and, using targeted proteomics, quantified a subset of the li ...

Impact of hepatic lipid accumulation and composition on glucose tolerance and insulin sensitivity: a longitudinal study in male and female mice

Rolf Gruetter, Hongxia Lei, Ana Francisca Leal Silva Soares

Background and aims: Metabolic disruptions characterized by high hepatic lipid content (HLC) are associated with impairments in whole body glucose homeostasis. To gain insight on the role of hepatic lipids in the metabolic performance in the absence artifi ...

Hyperpolarized 13C lactate as a substrate for in vivo metabolic studies in skeletal muscle

Rolf Gruetter, Arnaud Comment, Josefina Adriana Maria Bastiaansen, Hikari Ananda Infinity Yoshihara, Yuhei Takado

Resting skeletal muscle has a preference for the oxidation of lipids compared to carbohydrates and a shift towards carbohydrate oxidation is observed with increasing exercise. Lactate is not only an end product in skeletal muscle but also an important meta ...

Hepatic glucose sensing is required to preserve β cell glucose competence

Rolf Gruetter, Bernard Lanz, Frédéric Schütz, Carole Poitry-Yamate

Liver glucose metabolism plays a central role in glucose homeostasis and may also regulate feeding and energy expenditure. Here we assessed the impact of glucose transporter 2 (Glut2) gene inactivation in adult mouse liver (LG2KO mice). Loss of Glut2 suppr ...

The journey of resveratrol from yeast to human

Johan Auwerx

The natural polyphenolic compound resveratrol was first discovered in the 1940s. In the recent years, this compound received renewed interest as several findings implicated resveratrol as a potent SIRT1 activator capable of mimicking the effects of calorie ...
