Metabolic rescue of muscle and muscle stem cells in muscle disease

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 ...

Asperuloside Improves Obesity and Type 2 Diabetes through Modulation of Gut Microbiota and Metabolic Signaling

Johan Auwerx, Qi Zhu

Asperuloside (ASP) is an iridoid glycoside that is extracted from Eucommia leaves. Eucommia is used in traditional Chinese medicine and has a long history of benefits on health and longevity. Here, we investigated the impact of ASP on obesity-related metab ...

Renal Purge of Hemolymphatic Lipids Prevents the Accumulation of ROS-Induced Inflammatory Oxidized Lipids and Protects Drosophila from Tissue Damage

Bruno Lemaitre, Samuel Rommelaere, Xiaoxue Li

Animals require complex metabolic and physiological adaptations to maintain the function of vital organs in response to environmental stresses and infection. Here, we found that infection or injury in Drosophila induced the excretion of hemolymphatic lipid ...

Mitocellular communication: Shaping health and disease

Johan Auwerx, Sébastien Robert Victor Herzig, Adrienne Joëlle Laurence Mottis

Throughout the animal kingdom, mitochondria are the only organelles that retain their own genome and the transcription and translation machineries that are all essential for energy harvesting. Mitochondria have developed a complex communication network, al ...

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 ...

Mitochondria-specific photoactivation to monitor local sphingosine metabolism and function

Howard Riezman

Photoactivation ('uncaging') is a powerful approach for releasing bioactive small molecules in living cells. Current uncaging methods are limited by the random distribution of caged molecules within cells. We have developed a mitochondria-specific photoact ...

Cannabis use in early psychosis is associated with reduced glutamate levels in the prefrontal cortex

Rolf Gruetter, Lijing Xin, Kim Do

Recent studies have shown that cannabis may disrupt glutamate (Glu) signaling depressing Glu tone in frequent users. Current evidence have also consistently reported lower Glu-levels in various brain regions, particularly in the medial prefrontal cortex (m ...

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 ...

Stress, glucocorticoid receptor and social behaviors

Peripuberty, comprising childhood and adolescence, constitutes an important time window in the brain development and maturation. Exposure to prolonged stress during this period has been shown to increase the risk for the development of psychopathologies la ...

Neuronal Representation of Social Information in the Medial Amygdala of Awake Behaving Mice

Alexander Mathis

The medial amygdala (MeA) plays a critical role in processing species- and sex-specific signals that trigger social and defensive behaviors. However, the principles by which this deep brain structure encodes social information is poorly understood. We used ...
