Alterations of lipid homeostasis in morbid obese patients are partly reversed by bariatric surgery

Besides its beneficial effect on weight loss, gastric bypass surgery (GBS) may impact the circulating levels of phospho- and sphingolipids. However, long-term effects have not been explored. To investigate alterations in lipidomic signatures associated wit ...

Nicotinamide and Pyridoxine Stimulate Muscle Stem Cell Expansion and Enhance Regenerative Capacity During Aging

Sara Ancel, Sruthi Raja

Skeletal muscle relies on resident muscle stem cells (MuSCs) for growth and repair. Aging and muscle diseases impair MuSC function, leading to stem cell exhaustion and regenerative decline that contribute to the progressive loss of skeletal muscle mass and ...

Primary data for EPFL thesis "Metabolic regulation of cytokinesis in Schizosaccharomyces pombe"

Özge Uysal Özdemir

All cells need to be able to sense their environment, and adapt their metabolism, growth and cell division appropriately. In this study, I examined the response of Schizosaccharomyces pombe to a change in the carbon source and how that affects cytokinesis. ...

At the Intersection of Microbiota and Circadian Clock: Are Sexual Dimorphism and Growth Hormones the Missing Link to Pathology? Circadian Clock and Microbiota: Potential Egffect on Growth Hormone and Sexual Development

Benjamin Dieter Weger, Frédéric Bruno Martin Gachon

Reciprocal interactions between the host circadian clock and the microbiota are evidenced by recent literature. Interestingly, dysregulation of either the circadian clock or microbiota is associated with common human pathologies such as obesity, type 2 dia ...

A System for In Vivo Imaging of Hepatic Free Fatty Acid Uptake

Elena Goun, Grigory Karateev

Alterations in hepatic free fatty acid (FFA) uptake and metabolism contribute to the development of prevalent liver disorders such as hepatosteatosis. However, detecting dynamic changes in FFA uptake by the liver in live model organisms has proven difficul ...

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. ...

Bioenergetics-based modeling of Plasmodium falciparum metabolism reveals its essential genes, nutritional requirements, and thermodynamic bottlenecks

Vassily Hatzimanikatis, Meriç Ataman, Anush Chiappino-Pepe, Stepan Tymoshenko

Novel antimalarial therapies are urgently needed for the fight against drug-resistant para- sites. The metabolism of malaria parasites in infected cells is an attractive source of drug targets but is rather complex. Computational methods can handle this co ...

Navigating and Managing the Complexity of Genome Scale Metabolic Networks for Studies in Cellular Physiology and Industrial Biotechnology

Meriç Ataman

Metabolism is a network of biochemical reactions that converts carbon sources to cellu-lar fuels and building blocks. Metabolism of many organisms has been studied for many decades. These studies define metabolism as a very large and complex network. Stoic ...

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 ...

The Drosophila MAPK p38c Regulates Oxidative Stress and Lipid Homeostasis in the Intestine

Bruno Lemaitre, Sveta Chakrabarti

The p38 mitogen-activated protein (MAP) kinase signaling cassette has been implicated in stress and immunity in evolutionarily diverse species. In response to a wide variety of physical, chemical and biological stresses p38 kinases phosphorylate various su ...

The Schizosaccharomyces pombe septation initiation network (SIN) is required for spore formation in meiosis

Viesturs Simanis, Andrea Krapp

When nutrients are abundant, S. pombe cells grow as rods, dividing by fission after formation of a medially placed cell wall or division septum. Septum formation is triggered by a group of proteins, called the septation initiation network or SIN, that trig ...
