Investigation of physiological roles of AMPK-activated protein kinase y3

Clinical trials have shown that direct activators of an evolutionary-conserved metabolic sensor, AMP-activated protein kinase (AMPK), are beneficial in preventing/treating a range of metabolic disorders, including type 2 diabetes. These activators, includi ...

Glycogen metabolism is impaired in the brain of male type 2 diabetic Goto‐Kakizaki rats

João Miguel das Neves Duarte, Ana Francisca Leal Silva Soares

Diabetes impacts the central nervous system predisposing to cognitive decline. While glucose is the main source of energy fueling the adult brain, brain glycogen is necessary for adequate neuronal function, synaptic plasticity and memory. In this study, we ...

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, Nathalie Just, João Miguel das Neves Duarte, 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 ...

Lactate metabolism shift in CHO cell culture: the role of mitochondrial oxidative activity

Florian Maria Wurm, Martin Jordan, Mathieu Benjamin Stettler, Francesca Zagari

Lactate production is monitored in industrial processes as a crucial metabolite for cultured mammalian cells. Typically lactate is strongly produced during the exponential growth phase, while its net consumption is frequently observed when cells enter into ...

Elucidating the role of neuron-astrocyte metabolic coupling in learning and memory : molecular, genetic and behavioural approaches

Monika Tadi

The brain has very high energy demands that are mainly met by the circulating blood glucose to ensure its proper functioning. Thus, it is not surprising that though the human brain weighs only 2- 3% of the body weight, it consumes approximately 25% of tota ...

Multidisciplinary Analysis of the Metabolic Shift to Lactate Consumption in CHO Cell Culture

Francesca Zagari

Mammalian cells represent the most widely used host system for the industrial production of recombinant therapeutic proteins. In order to increase productivity, chemically defined media are often used and optimized to provide the cells with the necessary n ...

Altered Glycogen Metabolism in Cultured Astrocytes from Mice with Chronic Glutathione Deficit; Relevance for Neuroenergetics in Schizophrenia

Pierre Magistretti, Igor Allaman, Kim Do, Jean-Marie Petit

Neurodegenerative and psychiatric disorders including Alzheimer's, Parkinson's or Huntington's diseases and schizophrenia have been associated with a deficit in glutathione (GSH). In particular, a polymorphism in the gene of glutamate cysteine ligase modul ...

Ablation of the Tumor Suppressor Histidine Triad Nucleotide Binding Protein 1 is Protective Against Hepatic Ischemia/Reperfusion Injury

Gisèle Ferrand

The identification of cellular pathways capable of limiting ischemia/reperfusion (I/R) injury remains a frontier in medicine, and its clinical relevance is urgent. Histidine triad nucleotide binding protein 1 (HINT1) is a tumor suppressor that influences a ...

Non-invasive quantification of brain glycogen absolute concentration

Rolf Gruetter, Lijing Xin, Hongxia Lei, Ruud van Heeswijk, Hanne Frenkel, Sabrina Laus

The only currently available method to measure brain glycogen in vivo is C-13 NMR spectroscopy. Incorporation of C-13-labeled glucose (Glc) is necessary to allow glycogen measurement, but might be affected by turnover changes. Our aim was to measure glycog ...
