Perfect adaptation achieved by transport limitations governs the inorganic phosphate response in S. cerevisiae

Sebastian Maerkl, Shiyu Cheng, Hon Ming Andrew Yip, Evan James Olson, Michael Andrew Crone

Cells cope with and adapt to ever-changing environmental conditions. Sophisticated regulatory networks allow cells to adjust to these fluctuating environments. One such archetypal system is the Saccharomyces cerevisiae Pho regulon. When external inorganic ...

Sodium thiosulfate, a source of hydrogen sulfide, stimulates endothelial cell proliferation and neovascularization

Georges Wagnières, Jaroslava Joniová, Séverine Marguerite Urfer

Therapies to accelerate vascular repair are currently lacking. Pre-clinical studies suggest that hydrogen sulfide (H2S), an endogenous gasotransmitter, promotes angiogenesis. Here, we hypothesized that sodium thiosulfate (STS), a clinically relevant source ...

Proteomics reveals unique plasma signatures in constitutional thinness

Loïc Dayon, Jörg Hager, Nele Gheldof

Purpose Studying the plasma proteome of control versus constitutionally thin (CT) individuals, exposed to overfeeding, may give insights into weight-gain management, providing relevant information to the clinical entity of weight-gain resistant CT, and dis ...

The Appearance of the Warburg Effect in the Developing Avian Eye Characterized In Ovo: How Neurogenesis Can Remodel Neuroenergetics

Rolf Gruetter, Carole Poitry-Yamate, Antoine Timothée Cherix, Laurent Brodier

PURPOSE. The avian eye is an established model for exploring mechanisms that coordinate morphogenesis and metabolism during embryonic development. Less is known, however, about trafficking of bioenergetic and metabolic signaling molecules that are involved ...

Metabolic rescue of muscle and muscle stem cells in muscle disease

Peiling Luan

Duchenne muscular dystrophy (DMD), caused by the mutation of dystrophin gene, is an X-linked disorder that affects 1 in 3500 males, leading to progressive muscle degeneration and eventually resulting in premature death. Increasing evidence indicates that D ...

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. ...

Creatine in the central nervous system: From magnetic resonance spectroscopy to creatine deficiencies

Cristina Ramona Cudalbu, Veronika Rackayová

Creatine (Cr) is an important organic compound acting as intracellular high-energy phosphate shuttle and in energy storage. While located in most cells where it plays its main roles in energy metabolism and cytoprotection, Cr is highly concentrated in musc ...

AMPK alpha 1-LDH pathway regulates muscle stem cell self-renewal by controlling metabolic homeostasis

Lin Yang, Kei Sakamoto, Caterina Collodet, Laurent Bultot

Control of stem cell fate to either enter terminal differentiation versus returning to quiescence (self-renewal) is crucial for tissue repair. Here, we showed that AMP-activated protein kinase (AMPK), the master metabolic regulator of the cell, controls mu ...

Mycobacterium tuberculosis Phosphate Uptake System Component PstA2 Is Not Required for Gene Regulation or Virulence

John McKinney, Anna De Graff Tischler

The Mycobacterium tuberculosis genome encodes two complete high-affinity Pst phosphate-specific transporters. We previously demonstrated that a membrane-spanning component of one Pst system, PstA1, was essential both for M. tuberculosis virulence and for r ...

Composition and structure of Fe(III)-precipitates formed by Fe(II) oxidation in water at near-neutral pH: Interdependent effects of phosphate, silicate and Ca

Janet Gordon Hering

We studied the interdependent effects of phosphate, silicate and Ca on the formation of Fe(III)-precipitates by oxidation of 0.5 mM Fe(II) in near-neutral bicarbonate-buffered aqueous solutions at concentrations relevant for natural water resources. Comple ...

Multi-timescale Modeling of Activity-Dependent Metabolic Coupling in the Neuron-Glia-Vasculature Ensemble

Pierre Magistretti, Igor Allaman, Renaud Jolivet, Jay Coggan

Glucose is the main energy substrate in the adult brain under normal conditions. Accumulating evidence, however, indicates that lactate produced in astrocytes (a type of glial cell) can also fuel neuronal activity. The quantitative aspects of this so-calle ...

Systematic lipidomic analysis of yeast protein kinase and phosphatase mutants reveals novel insights into regulation of lipid homeostasis

Fabrice David, Howard Riezman, Manuele Piccolis

The regulatory pathways required to maintain eukaryotic lipid homeostasis are largely unknown. We developed a systematic approach to uncover new players in the regulation of lipid homeostasis. Through an unbiased mass spectrometry-based lipidomic screening ...

The Phosphate Specific Transport (Pst) System in Fast- and Slow-Growing Mycobacteria

Cyntia De Piano

Although mycobacteria are known to accumulate polyphosphate (PolyP), a linear polymer of orthophosphate, when subjected to stresses, the exact roles of this molecule are not yet clearly understood. We found that deletion of the pstA gene encoding for a tra ...

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 ...

Role of the Glyoxalase System in Astrocyte-Mediated Neuroprotection

Pierre Magistretti, Igor Allaman, Thierry Laroche, Jiangyan Yang, Jean-Marie Petit

The glyoxalase system is the most important pathway for the detoxification of methylglyoxal (MG), a highly reactive dicarbonyl compound mainly formed as a by-product of glycolysis. MG is a major precursor of advanced glycation end products (AGEs), which ar ...

Mitochondrial Matrix Calcium Is an Activating Signal for Hormone Secretion

Kristina Schoonjans, Chikage Mataki, Andreas Wiederkehr

Mitochondrial Ca2+ signals have been proposed to accelerate oxidative metabolism and ATP production to match Ca2+-activated energy-consuming processes. Efforts to understand the signaling role of mitochondrial Ca2+ have been hampered by the inability to ma ...

Inhibition of calcineurin by FK506 protects against polyglutamine-huntingtin toxicity through an increase of huntingtin phosphorylation at S421

Patrick Aebischer, Nicole Déglon

Huntington's disease (HD) is caused by an abnormal expanded polyglutamine (polyQ) repeat in the huntingtin protein. Insulin-like growth factor-1 acting through the prosurvival kinase Akt mediates the phosphorylation of huntingtin at S421 and inhibits the t ...
