In vivo (13)C MRS in the mouse brain at 14.1 Tesla and metabolic flux quantification under infusion of [1,6-(13)C2]glucose

Rolf Gruetter, Cristina Ramona Cudalbu, Bernard Lanz, Carole Poitry-Yamate, Marta Lai, Corina Mihaela Berset

In vivo (13)C magnetic resonance spectroscopy (MRS) enables the investigation of cerebral metabolic compartmentation while, e.g. infusing (13)C-labeled glucose. Metabolic flux analysis of (13)C turnover previously yielded quantitative information of glutam ...

Image-Derived Input Function from the Vena Cava for 18F-FDG PET Studies in Rats and Mice

Rolf Gruetter, Bernard Lanz, Carole Poitry-Yamate

Measurement of arterial input function is a restrictive aspect for quantitative 18F-FDG PET studies in rodents because of their small total blood volume and the related difficulties in withdrawing blood. METHODS: In the present study, we took advantage of ...

Experimental peripheral arterial disease: new insights into muscle glucose uptake, macrophage, and T-cell polarization during early and late stages

Rolf Gruetter, Carole Poitry-Yamate

Peripheral arterial disease (PAD) is a common disease with increasing prevalence, presenting with impaired walking ability affecting patient's quality of life. PAD epidemiology is known, however, mechanisms underlying functional muscle impairment remain un ...

Direct mapping of 19F in 19FDG-6P in brain tissue at subcellular resolution using soft X-ray fluorescence

Rolf Gruetter, Carole Poitry-Yamate

Low energy x-ray fluorescence (LEXRF) detection was optimized for imaging cerebral glucose metabolism by mapping the fluorine LEXRF signal of 19 F in 19 FDG, trapped as intracellular 19 F-deoxyglucose-6-phosphate ( 19 FDG-6P) at 1μm spatial resolution from ...

Hepatic glucose sensing is required to preserve β cell glucose competence

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

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 ...

Feasibility of direct mapping of cerebral fluorodeoxy-D-glucose metabolism in situ at subcellular resolution using soft X-ray fluorescence

Rolf Gruetter, Carole Poitry-Yamate, Mario Gaetano Lepore, Vincent Gajdosik

Glucose metabolism is difficult to image with cellular resolution in mammalian brain tissue, particularly with (18) fluorodeoxy-D-glucose (FDG) positron emission tomography (PET). To this end, we explored the potential of synchrotron-based low-energy X-ray ...

Bioavailable copper modulates oxidative phosphorylation and growth of tumors

Johan Auwerx, Douglas Hanahan, Carole Poitry-Yamate, Pénélope Andreux, Seiko Ishida

Copper is an essential trace element, the imbalances of which are associated with various pathological conditions, including cancer, albeit via largely undefined molecular and cellular mechanisms. Here we provide evidence that levels of bioavailable copper ...

68Ga-NODAGA-RGDyK for αvβ3 integrin PET imaging. Preclinical investigation and dosimetry

Carole Poitry-Yamate, Christian Rüegg, Serge Baechler, David Viertl

To visualize neovasculature and/or tumour integrin αvβ3 we selected the binding moiety Arg-Gly-Asp-D-Tyr-Lys (RGDyK) coupled to NODAGA for labeling with 68Ga. ...
