Abnormal brain oxygen homeostasis in an animal model of liver disease

Cristina Ramona Cudalbu Moldovan, Dunja Simicic, Katarzyna Pierzchala

Background & Aims: Increased plasma ammonia concentration and consequent disruption of brain energy metabolism could underpin the pathogenesis of hepatic encephalopathy (HE). Brain energy homeostasis relies on effective maintenance of brain oxygenation, an ...

Radical-free hyperpolarized MRI using endogenously occurring pyruvate analogues and UV-induced nonpersistent radicals

Rolf Gruetter, Josefina Adriana Maria Bastiaansen, Hikari Ananda Infinity Yoshihara, Andrea Capozzi, Alice Radaelli, Claudia Christina Zanella

It was recently demonstrated that nonpersistent radicals can be generated in frozen solutions of metabolites such as pyruvate by irradiation with UV light, enabling radical-free dissolution dynamic nuclear polarization. Although pyruvate is endogenous, the ...

A community-based transcriptomics classification and nomenclature of neocortical cell types

Parviz Ghaderi

To understand the function of cortical circuits, it is necessary to catalog their cellular diversity. Past attempts to do so using anatomical, physiological or molecular features of cortical cells have not resulted in a unified taxonomy of neuronal or glia ...

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. ...

AMP-activated protein kinase : strategies for activation and downstream target identification

Serge Thanh Son Ducommun

AMP-activated protein kinase (AMPK) is an evolutionally conserved key sensor of cellular energy status. Under conditions of cellular energy stress, AMPK is activated and will switch off anabolic processes that consume ATP, while activating catabolic proces ...

A Cellular Perspective on Brain Energy Metabolism and Functional Imaging

Pierre Magistretti, Igor Allaman

The energy demands of the brain are high: they account for at least 20% of the body's energy consumption. Evolutionary studies indicate that the emergence of higher cognitive functions in humans is associated with an increased glucose utilization and expre ...

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

Florian Maria Wurm, Martin Jordan, Mathieu Benjamin Stettler

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 ...

Genes Involved in the Astrocyte-Neuron Lactate Shuttle (ANLS) Are Specifically Regulated in Cortical Astrocytes Following Sleep Deprivation in Mice

Pierre Magistretti, Sophie Burlet Godinot

Study Objectives: There is growing evidence indicating that in order to meet the neuronal energy demands, astrocytes provide lactate as an energy substrate for neurons through a mechanism called "astrocyte-neuron lactate shuttle" (ANLS). Since neuronal act ...
