Inhibition of CERS1 in skeletal muscle exacerbates age-related muscle dysfunction

Johan Auwerx, Olivier Burri, Xiaoxu Li, Tanes Imamura de Lima, Giacomo Vincenzo Giorgio Von Alvensleben, Martin Rainer Wohlwend, Pirkka-Pekka Untamo Laurila, Ludger Jan Elzuë Goeminne, Barbara Moreira Crisol, Amélia Lalou, Renata Mangione

Age-related muscle wasting and dysfunction render the elderly population vulnerable and incapacitated, while underlying mechanisms are poorly understood. Here, we implicate the CERS1 enzyme of the de novo sphingolipid synthesis pathway in the pathogenesis ...

Imaging Cu2+ binding to charged phospholipid membranes by high-throughput second harmonic wide-field microscopy

Sylvie Roke, David Roesel, Seonwoo Lee

The interaction of divalent copper ions (Cu2+) with cell membranes is crucial for a variety of physiological processes of cells, such as hormone synthesis and cellular energy production. These interactions would not be possible without membrane hydration. ...

Brain NAD Is Associated With ATP Energy Production and Membrane Phospholipid Turnover in Humans

Rolf Gruetter, Lijing Xin, Özlem Ipek, Maya Shevlyakova

The brain requires a large amount of energy, mostly derived from the metabolism of glucose, which decreases substantially with age and neurological diseases. While mounting evidence in model organisms illustrates the central role of brain nicotinamide aden ...

Live-cell lipid biochemistry reveals a role of diacylglycerol side-chain composition for cellular lipid dynamics and protein affinities

Milena Maria Schuhmacher, Pavel Barahtjan

Every cell produces thousands of distinct lipid species, but insight into how lipid chemical diversity contributes to biological signaling is lacking, particularly because of a scarcity of methods for quantitatively studying lipid function in living cells. ...

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 ...

Chemistry of Lipid Membranes from Models to Living Systems: A Perspective of Hydration, Surface Potential, Curvature, Confinement and Heterogeneity

Sylvie Roke, Orly Bagunu Tarun, Halil Ibrahim Okur

Lipid membranes provide diverse and essential functions in our cells relating to transport, energy harvesting and signaling. This variety of functions is controlled by the molecular architecture, such as the presence of hydrating water, specific chemical c ...

A Click Cage: Organelle‐Specific Uncaging of Lipid Messengers

Lipid messengers exert their function on short time scales at distinct subcellular locations, yet most experimental approaches for perturbing their levels trigger cell-wide concentration changes. Herein, we report on a coumarin-based photocaging group that ...

Lipid exchange and signaling at ER–Golgi contact sites

Meticulous observations of the cell perinuclear region where the Golgi and the endoplasmic reticulum (ER) networks intermingle have revealed close contact sites of barely 20 nm between these two organelles. Recent studies demonstrate that molecular machine ...

Sphingolipid metabolic flow controls phosphoinositide turnover at the trans ‐Golgi network

Giovanni D'Angelo, Howard Riezman, Riccardo Rizzo

Sphingolipids are membrane lipids globally required for eukaryotic life. The sphingolipid content varies among endomembranes with pre- and post-Golgi compartments being poor and rich in sphingolipids, respectively. Due to this different sphingolipid conten ...

Interfacial Structure and Hydration of 3D Lipid Monolayers in Aqueous Solution

Sylvie Roke, Nikolay Smolentsev, Yixing Chen, Halil Ibrahim Okur, Evangelia Zdrali

Three-dimensional (3D) phospholipid monolayers at hydrophobic surfaces are ubiquitous and found in nature as adiposome organelles or in man-made materials such as drug delivery systems. However, the molecular level understanding of such monolayers remains ...
