Impairment of Glycolysis-Derived L-Serine Production in Astrocytes Contributes to Cognitive Deficits in Alzheimer's Disease

Alteration of brain aerobic glycolysis is often observed early in the course of Alzheimer's disease (AD). Whether and how such metabolic dysregulation contributes to both synaptic plasticity and behavioral deficits in AD is not known. Here, we show that th ...

Sources and variability of CO 2 in a pre‐alpine stream gravel bar

Tom Ian Battin

Gravel bars (GBs) contribute to carbon dioxide (CO2) emissions from stream corridors, with CO2 concentrations and emissions dependent on prevailing hydraulic, biochemical, and physicochemical onditions. We investigated CO2 concentrations and fluxes across ...

Niacin: an old lipid drug in a new NAD(+) dress

Johan Auwerx, Mario Romani, Elena Katsyuba, Dina Hofer

Niacin, the first antidyslipidemic drug, has been at the center stage of lipid research for many decades before the discovery of statins. However, to date, despite its remarkable effects on lipid profiles, the clinical outcomes of niacin treatment on cardi ...

The NAD-Booster Nicotinamide Riboside Potently Stimulates Hematopoiesis through Increased Mitochondrial Clearance

Johan Auwerx, Matthias Lütolf, Bart Deplancke, Carlos Canto Alvarez, Olaia Maria Naveiras Torres-Quiroga, George Coukos, Aurélien Laurent Jean-Charles Oggier, Loïc Tauzin, Dongryeol Ryu, Eija Riitta Pirinen, Pedro Romero, Vasco Ledebur de Antas de Campos, Mukul Girotra, Joanna Ratajczak, Josefine Catharina Pedersen Tratwal, Nicola Vannini, Pernille Yde Rainer, Gennady Nikitin, Federico Sizzano, Simone Ragusa, Vincent Trachsel, Sonja Giger, Shanti Rojas-Sutterlin, Yannick Lionel Yersin, Martin Ehrbar

It has been recently shown that increased oxidative phosphorylation, as reflected by increased mitochondrial activity, together with impairment of the mitochondrial stress response, can severely compromise hematopoietic stem cell (HSC) regeneration. Here w ...

Astrocytic and neuronal oxidative metabolism are coupled to the rate of glutamate-glutamine cycle in the tree shrew visual cortex

Rolf Gruetter, Gregor Rainer, João Miguel das Neves Duarte, Nathalie Just, Sarah Catherine Sonnay, Anne Catherine Clerc

Astrocytes play an important role in glutamatergic neurotransmission, namely by clearing synaptic glutamate and converting it into glutamine that is transferred back to neurons. The rate of this glutamate–glutamine cycle (VNT) has been proposed to couple t ...

Comparison of hock- and footpad-injection as a prostate adenocarcinoma model in rats

BackgroundObjective of this study is a feasibility-test comparing hock- and footpad-injection in rats with inoculated MatLyLu - adenocarcinoma tumor model. This study compares the development of an adenocarcinoma model (MatLyLu) in 12 Copenhagen rats. Two ...

Pyruvate cellular uptake and enzymatic conversion probed by dissolution DNP-NMR: the impact of overexpressed membrane transporters

Arnaud Comment, Paul Romeo Vasos, Riccardo Balzan

Pyruvate membrane crossing and its lactate dehydrogenase-mediated conversion to lactate in cells featuring different levels of expression of membrane monocarboxylate transporters (MCT4) were probed by dissolution dynamic nuclear polarization-enhanced NMR. ...

Understanding reprogramming of cancer cell metabolism using metabolic modeling

Vassily Hatzimanikatis, Maria Masid Barcon, Joana Raquel Pinto Vieira

Cancer cells have been observed to undergo a metabolic reprogramming in which glycolytic fluxes are upregulated whereas oxidative phosphorylation is downregulated. This metabolic phenotype is known as theWarburg effect and it is observed even under high ox ...

Neutrophils and Snail Orchestrate the Establishment of a Pro-tumor Microenvironment in Lung Cancer

Nicolas Jean Philippe Guex, Nadine Fournier, Miguel Garcia, Etienne Meylan, Alessandra Piersigilli, Julien Robert Rémi Faget, Inti Zlobec, Gael Luis Boivin, Svenja Johanna Groeneveld, Loïc Steiner, Ioannis Xenarios

Understanding the immune compartment of tumors facilitates the development of revolutionary new therapies. We used a Kras(G12D)-driven mouse model of lung cancer to establish an immune signature and identified a contribution of Gr1 + neutrophils to disease ...

ATP and NADPH coated iron oxide nanoparticles for targeting of highly metabolic tumor cells

Dominique Bonvin, Heinrich Hofmann

The metabolic activity of tumor cells is known to be higher as compared to that of normal cells, which has been previously exploited to deliver nanomedicines to highly metabolic tumor cells. Unfortunately, current strategies, which are mostly based on comp ...
