Metabolomics reveals tepotinib‐related mitochondrial dysfunction in MET activating mutations‐driven models

Katarzyna Pierzchala

Genetic aberrations in the hepatocyte growth factor receptor tyrosine kinase MET induce oncogenic addiction in various types of human cancers, advocating MET as a viable anticancer target. Here, we report that MET signaling plays an important role in confe ...

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

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

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 ...

Feasibility of in vivo measurement of glucose metabolism in the mouse hypothalamus by (1) H-[(13) C] MRS at 14.1T

Rolf Gruetter, Hongxia Lei, João Miguel das Neves Duarte, Bernard Lanz, Antoine Timothée Cherix, Blanca Lizarbe Serra

PURPOSE: Determine the feasibility of (1) H-[(13) C] MRS in the mouse hypothalamus using a 14.1T magnet. METHODS: We optimized the design of a (1) H-[(13) C] surface coil to maximize the signal-to-noise ratio of (1) H-[(13) C] MRS in the mouse hypothalamus ...

Atomistic simulation of bio-relevant ionic and organic species interacting with rutile - Towards the understanding of apatite formation

Azade Yazdan Yar

Atomistic simulation methods, namely molecular dynamics and well-tempered metadynamics, are used in this thesis to investigate apatite formation from different aspects. First, ions which are more abundant in SBFs under physiological conditions were identif ...

Adsorption Free Energy of Single Amino Acids at the Rutile (110)/ Water Interface Studied by Well-Tempered Metadynamics

Paul Bowen, Ulrich Aschauer, Azade Yazdan Yar

Single amino acids are present in blood plasma and are the building blocks of larger organic residues. Their interaction with surfaces is therefore crucial for biomedical applications in contact with blood. In this work, we use well-tempered metadynamics t ...

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 ...

Cannabis use in early psychosis is associated with reduced glutamate levels in the prefrontal cortex

Rolf Gruetter, Lijing Xin

Recent studies have shown that cannabis may disrupt glutamate (Glu) signaling depressing Glu tone in frequent users. Current evidence have also consistently reported lower Glu-levels in various brain regions, particularly in the medial prefrontal cortex (m ...

Social isolation stress and chronic glutathione deficiency have a common effect on the glutamine-to-glutamate ratio and myo-inositol concentration in the mouse frontal cortex

João Miguel das Neves Duarte, Rolf Gruetter, Alberto Corcoba

Environmental stress can interact with genetic predisposition to increase the risk of developing psychopathology. In this work, we tested the hypothesis that social isolation stress interacts with impaired glutathione synthesis and have cumulative effects ...
