Mechanisms and functions of protein S-acylation

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Francisco De Magalhães Sarmento Ribeiro De Mesquita

Over the past two decades, protein S-acylation (often referred to as S-palmitoylation) has emerged as an important regulator of vital signalling pathways. S-Acylation is a reversible post-translational modification that involves the attachment of a fatty a ...

Measuring Glycolytic Activity with Hyperpolarized [2H7, U-13C6] D-Glucose in the Naive Mouse Brain under Different Anesthetic Conditions

Rolf Gruetter, Bernard Lanz, Mor-Miri Mishkovsky, Andrea Capozzi, Yves Pilloud, Emmanuelle Ines Flatt

Glucose is the primary fuel for the brain; its metabolism is linked with cerebral function. Different magnetic resonance spectroscopy (MRS) techniques are available to assess glucose metabolism, providing complementary information. Our first aim was to inv ...

Investigation of physiological roles of AMPK-activated protein kinase y3

Philipp Jurijvic Rhein

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 ...

Investigation of the specificity and mechanism of action of the ULK1/AMPK inhibitor SBI-0206965

Katyayanee Neopane

SBI-0206965, originally identified as an inhibitor of the autophagy initiator kinase ULK1, has recently been reported as a more potent and selective AMP-activated protein kinase (AMPK) inhibitor relative to the widely used, but promiscuous inhibitor Compou ...

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, Sakura Sophie Nussbaum

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 ...

Measuring glucose cerebral metabolism in the healthy mouse using hyperpolarized C-13 magnetic resonance

Rolf Gruetter, Arnaud Comment, Mor-Miri Mishkovsky

The mammalian brain relies primarily on glucose as a fuel to meet its high metabolic demand. Among the various techniques used to study cerebral metabolism, C-13 magnetic resonance spectroscopy (MRS) allows following the fate of C-13-enriched substrates th ...

A multiscale study of the role of dynamin in the regulation of glucose uptake

Martinus Adela Maria Gijs, Johan Auwerx, Kristina Schoonjans, Laurent Mouchiroud, Raphaël Etienne Jean Trouillon, Keir Joe Menzies, Maria Cristina Letizia

Glucose uptake in muscle cells in response to insulin is a fundamental mechanism for metabolism. The inability of cells to mobilize the specific glucose transporter GLUT4 is believed to be at least partially accountable for diseases, like diabetes, where c ...

Mediatorless, Reversible Optical Nanosensor Enabled through Enzymatic Pocket Doping

Ardemis Anoush Boghossian, Vitalijs Zubkovs, Benjamin Paul Johanès Gabriel Lambert, Nils Schürgers

This study presents a reversible, mediatorless, near-infrared glucose sensor based on glucose oxidase-wrapped SWCNTs. A combination of fluorescence, absorption, and Raman spectroscopy measurements suggest a fluorescence enhancement mechanism based on local ...

New optical tools for non-invasive imaging and quantification of glucose and nicotinamide riboside in living cells and animals

Aleksandra Konovalova

Glucose is one of the most important metabolites that plays a key role in living organisms, as it is the primary energy source. Glucose metabolism is also an integral part in the pathogenesis of diabetes and cancer. Despite this tremendous impact of glucos ...

Imaging liver and brain glycogen metabolism at the nanometer scale

Anders Meibom, Arnaud Comment, Graham Knott, Stéphane Laurent Escrig, Yuhei Takado

In mammals, glycogen synthesis and degradation are dynamic processes regulating blood and cerebral glucose-levels within a well-defined physiological range. Despite the essential role of glycogen in hepatic and cerebral metabolism, its spatiotemporal distr ...

Farnesoid X receptor inhibits glucagon-like peptide-1 production by enteroendocrine L cells

Kristina Schoonjans, Alessia Perino

Bile acids are signalling molecules, which activate the transmembrane receptor TGR5 and the nuclear receptor FXR. BA sequestrants (BAS) complex bile acids in the intestinal lumen and decrease intestinal FXR activity. The BAS-BA complex also induces glucago ...

Imaging the time-integrated cerebral metabolic activity with subcellular resolution through nanometer-scale detection of biosynthetic products deriving from (13)C-glucose

Anders Meibom, Arnaud Comment, Graham Knott, Stéphane Laurent Escrig, Yuhei Takado

Glucose is the primary source of energy for the brain but also an important source of building blocks for proteins, lipids, and nucleic acids. Little is known about the use of glucose for biosynthesis in tissues at the cellular level. We demonstrate that l ...

Enhanced Conversion of Carbohydrates to the Platform Chemical 5-Hydroxymethylfurfural Using Designer Ionic Liquids

Paul Joseph Dyson, Rosario Scopelliti, Gabor Laurenczy, Zhaofu Fei, Ning Yan, Sviatlana Siankevich

5-Hydroxymethylfurfural (HMF) is a key platform chemical that may be obtained from various cellulosic (biomass) derivatives. Previously, it has been shown that ionic liquids (ILs) facilitate the catalytic conversion of glucose into HMF. Herein, we demonstr ...
