Assessing dystrophies and other muscle diseases at the nanometer scale by atomic force microscopy

Giovanni Dietler, Harald Brune, Andrzej Kulik, Nicolas Mermod, Guillaume Witz, Stefania Puttini

Aim: Atomic force microscopy nanoindentation of myofibers was used to assess and quantitatively diagnose muscular dystrophies from human patients. Materials & methods: Myofibers were probed from fresh or frozen muscle biopsies from human dystrophic patient ...

High expression of the aspartate–glutamate carrier Aralar1 favors lactate consumption in CHO cell culture

Florian Maria Wurm, Lucia Baldi Unser, Martin Jordan, Mathieu Benjamin Stettler, Francesca Zagari

Process performance of mammalian cell cultures can be strongly impacted by high lactate accumulation, which can be a clone or media-dependent characteristic. In this study, the expression of specific genes was measured in several Chinese hamster ovary cell ...

Significant Molecular and Systemic Adaptations after Repeated Sprint Training in Hypoxia

Jean-Marc Vesin, Grégoire Millet

While intermittent hypoxic training (IHT) has been reported to evoke cellular responses via hypoxia inducible factors (HIFs) but without substantial performance benefits in endurance athletes, we hypothesized that repeated sprint training in hypoxia could ...

Measurements of Glycogen Metabolism in the Living Brain

Rolf Gruetter

To maintain brain function, the combustion of glucose for the generation of energy (ATP) is essential, yet the brain maintains fuel storage in the form of glial glycogen. Although brain glycogen levels are lower than those in the liver, they exceed the nor ...

LRH-1-dependent glucose sensing determines intermediary metabolism in liver

Johan Auwerx, Kristina Schoonjans, Norman Lionel Moullan, Chikage Mataki, Hiroyasu Yamamoto, Taoufiq Harach, Maaike Hélène Oosterveer

Liver receptor homolog 1 (LRH-1), an established regulator of cholesterol and bile acid homeostasis, has recently emerged as a potential drug target for liver disease. Although LRH-1 activation may protect the liver against diet-induced steatosis and insul ...

Restoration of direct pathway glycogen synthesis flux in the STZ-diabetes rat model by insulin administration

Ana Francisca Leal Silva Soares

Type 1 diabetes subjects are characterized by impaired direct pathway synthesis of hepatic glycogen that is unresponsive to insulin therapy. Since it is not known whether this is an irreversible defect of insulin-dependent diabetes, direct and indirect pat ...

A comparison of in vivo (13) C MR brain glycogen quantification at 9.4 and 14.1 T

Rolf Gruetter, Yves Pilloud, Ruud van Heeswijk

The high molecular weight and low concentration of brain glycogen render its noninvasive quantification challenging. Therefore, the precision increase of the quantification by localized (13) C MR at 9.4 to 14.1 T was investigated. Signal-to-noise ratio inc ...

Comparing localized and nonlocalized dynamic 31P magnetic resonance spectroscopy in exercising muscle at 7T

Christine Nabuurs

By improving spatial and anatomical specificity, localized spectroscopy can enhance the power and accuracy of the quantitative analysis of cellular metabolism and bioenergetics. Localized and nonlocalized dynamic 31P magnetic resonance spectroscopy using a ...

Altered Glycogen Metabolism in Cultured Astrocytes from Mice with Chronic Glutathione Deficit; Relevance for Neuroenergetics in Schizophrenia

Pierre Magistretti, Igor Allaman, Kim Do, Jean-Marie Petit

Neurodegenerative and psychiatric disorders including Alzheimer's, Parkinson's or Huntington's diseases and schizophrenia have been associated with a deficit in glutathione (GSH). In particular, a polymorphism in the gene of glutamate cysteine ligase modul ...

Phosphocreatine line with changes in localised 31P MRS of exercising muscle at 7T

Rolf Gruetter, Christine Nabuurs

The aim was to investigate changes in the line width of high-energy phosphates solely originating from the intramyocellular compartment by temporally resolved localised 31P-MRS after aerobic calf muscle exercise. Semi-Laser [2] localised 31P-MRS of gastroc ...
