Transient vitamin B5 starving improves mammalian cell homeostasis and protein production

Maintaining a metabolic steady state is essential for an organism's fitness and survival when confronted with environmental stress, and metabolic imbalance can be reversed by exposing the organism to fasting. Here, we attempted to apply this physiological ...

The Appearance of the Warburg Effect in the Developing Avian Eye Characterized In Ovo: How Neurogenesis Can Remodel Neuroenergetics

Rolf Gruetter, Carole Poitry-Yamate, Antoine Timothée Cherix, Laurent Brodier

PURPOSE. The avian eye is an established model for exploring mechanisms that coordinate morphogenesis and metabolism during embryonic development. Less is known, however, about trafficking of bioenergetic and metabolic signaling molecules that are involved ...

N-acetylaspartate availability is essential for juvenile survival on fat-free diet and determines metabolic health

Johan Auwerx, Dina Hofer

N-acetylaspartate (NAA) is synthesized by aspartate N-acetyltransferase (gene: Nat8l) from acetyl-coenzyme A and aspartate. In the brain, NAA is considered an important energy metabolite for lipid synthesis. However, the role of NAA in peripheral tissues r ...

Ultra high magnetic field for glial contribution into brain metabolism studied by MR spectroscopy and CEST methods for molecular imaging of glycogen

Elise Marie Catherine Vinckenbosch

Magnetic resonance at ultra-high field increases signal and spectral dispersion. In this thesis, I use those characteristics to investigate three different subjects in 13C spectroscopy, hyperpolarized methods and chemical exchange saturation transfer (CEST ...

Energy metabolism in the rat cortex under thiopental anaesthesia measured

Rolf Gruetter, João Miguel das Neves Duarte, Nathalie Just, Sarah Catherine Sonnay

Barbiturates, commonly used as general anaesthetics, depress neuronal activity and thus cerebral metabolism. Moreover, they are likely to disrupt the metabolic support of astrocytes to neurons, as well as the uptake of nutrients from circulation. By employ ...

Nutritional input from dinoflagellate symbionts in reef-building corals is minimal during planula larval life stage

Anders Meibom, Isabelle Domart-Coulon, Christophe Kopp

Dispersion of larval offspring is of fundamental ecological importance to sessile marine organisms. Photosymbiotic planulae emitted by many reef-forming corals may travel over large distances before settling to form a new colony. It is not clear whether th ...

A rheostat mechanism governs the bifurcation of carbon flux in mycobacteria

Matteo Dal Peraro, John McKinney, Florence Pojer, Giulia Fonti, Paul Murima, Tarun Chopra

Fatty acid metabolism is an important feature of the pathogenicity of Mycobacterium tuberculosis during infection. Consumption of fatty acids requires regulation of carbon flux bifurcation between the oxidative TCA cycle and the glyoxylate shunt. In Escher ...

Brain energy metabolism measured by 13C magnetic resonance spectroscopy in vivo upon infusion of [3-13C]lactate

Rolf Gruetter, João Miguel das Neves Duarte, Freya-Merret Girault

The brain uses lactate produced by glycolysis as an energy source. How lactate originated from the blood stream is used to fuel brain metabolism is not clear. The current study measures brain metabolic fluxes and estimates the amount of pyruvate that becom ...

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 ...
