Hippo-YAP/TAZ signalling coordinates adipose plasticity and energy balance by uncoupling leptin expression from fat mass

Johan Auwerx, Jun Yong Kim, Maroun Bou Sleiman, Xiaoxu Li

Adipose tissues serve as an energy reservoir and endocrine organ, yet the mechanisms that coordinate these functions remain elusive. Here, we show that the transcriptional coregulators, YAP and TAZ, uncouple fat mass from leptin levels and regulate adipocy ...

Evidence for a neuromuscular circuit involving hypothalamic interleukin-6 in the control of skeletal muscle metabolism

Vera Monica Lemos Da Silva, Ludger Jan Elzuë Goeminne

Hypothalamic interleukin-6 (IL6) exerts a broad metabolic control. Here, we demonstrated that IL6 activates the ERK1/2 pathway in the ventromedial hypothalamus (VMH), stimulating AMPK/ACC signaling and fatty acid oxidation in mouse skeletal muscle. Bioinfo ...

Assessment of Aspartate and Bicarbonate Produced From Hyperpolarized [1-13C]Pyruvate as Markers of Renal Gluconeogenesis

Arnaud Comment, Hikari Ananda Infinity Yoshihara

As both a consumer and producer of glucose, the kidney plays a significant role in glucose homeostasis. Measuring renal gluconeogenesis requires invasive techniques, and less invasive methods would allow renal gluconeogenesis to be measured more routinely. ...

The DEAD-box RNA helicase CshA is required for fatty acid homeostasis inStaphylococcus aureus

Bianca Marie Petrignani

Staphylococcus aureusis an opportunistic pathogen that can grow in a wide array of conditions: on abiotic surfaces, on the skin, in the nose, in planktonic or biofilm forms and can cause many type of infections. Consequently,S.aureusmust be able to adapt r ...

PHD3 Loss Promotes Exercise Capacity and Fat Oxidation in Skeletal Muscle

Johan Auwerx, Hao Li, Daniel Garcia

Rapid alterations in cellular metabolism allow tissues to maintain homeostasis during changes in energy availability. The central metabolic regulator acetyl-CoA carboxylase 2 (ACC2) is robustly phosphorylated during cellular energy stress by AMP-activated ...

Sterol regulatory element binding protein 1 couples mechanical cues and lipid metabolism

Giovanni Sorrentino

Sterol regulatory element binding proteins (SREBPs) are a family of transcription factors that regulate lipid biosynthesis and adipogenesis by controlling the expression of several enzymes required for cholesterol, fatty acid, triacylglycerol and phospholi ...

Novel Molecular Probes for Non-invasive Optical Imaging of Fatty Acid and Triglyceride Uptake in Living Animals

Grigory Karateev

Molecular imaging allows noninvasive visualization of biological processes in their native environment within living systems. It can give a better understanding of fundamental biology, help in identifying disease mechanisms and visualizing pathological tis ...

Transforming Growth Factor beta/Activin signaling in neurons increases susceptibility to starvation

Bruno Lemaitre, Xiaoxue Li, Wen Bin Chng

Animals rely on complex signaling network to mobilize its energy stores during starvation. We have previously shown that the sugar-responsive TGF beta/Activin pathway, activated through the TGF beta ligand Dawdle, plays a central role in shaping the post-p ...

Impaired SUMOylation of nuclear receptor LRH-1 promotes nonalcoholic fatty liver disease

Kristina Schoonjans, Dongryeol Ryu, Xu Wang, Vera Monica Lemos Da Silva, Maaike Hélène Oosterveer, Pan Xu, Hadrien Charles Edouard Demagny

Hepatic steatosis is caused by metabolic imbalances that could be explained in part by an increase in de novo lipogenesis that results from increased sterol element binding protein 1 (SREBP-1) activity. The nuclear receptor liver receptor homolog 1 (LRH-1) ...

Energy metabolism in the rat cortex under thiopental anaesthesia measured

João Miguel das Neves Duarte, Rolf Gruetter, Nathalie Just, Sarah Catherine Sonnay

Barbiturates, commonly used as general anaesthetics, depress neuronal activity and thus cerebral metabolism. Moreover, they are likely to disrupt the metabolic support of astrocytes to neurons, as well as the uptake of nutrients from circulation. By employ ...

Phosphorylation of the nuclear receptor co-repressor 1 by protein kinase B (PKB/Akt) switches its co-repressor targets in the liver

Johan Auwerx, Kristina Schoonjans, Dongryeol Ryu, Xu Wang, Adriano Maida

The nuclear receptor corepressor 1 (NCoR1) is a transcriptional co-regulator that has wide-ranging effects on gene expression patterns. In the liver, NCoR1 represses lipid synthesis in the fasting state, whereas it inhibits the activation of PPARα upon fee ...

Characterization of hepatic fatty acids in mice with reduced liver fat by ultra-short echo time (1) H-MRS at 14.1 T in vivo

Rolf Gruetter, Ana Francisca Leal Silva Soares, Hongxia Lei

Alterations in the hepatic lipid content (HLC) and fatty acid composition are associated with disruptions in whole body metabolism, both in humans and in rodent models, and can be non-invasively assessed by (1) H-MRS in vivo. We used (1) H-MRS to character ...

Delayed bactericidal response of Mycobacterium tuberculosis to bedaquiline involves remodelling of bacterial metabolism

John McKinney, Neeraj Dhar, Muhittin Emre Özdemir

Bedaquiline (BDQ), an ATP synthase inhibitor, is the first drug to be approved for treatment of multidrug-resistant tuberculosis in decades. Though BDQ has shown excellent efficacy in clinical trials, its early bactericidal activity during the first week o ...

Real-Time Noninvasive Imaging of Fatty Acid Uptake in Vivo

Gennady Nikitin

Detection and quantification of fatty acid fluxes in animal model systems following physiological, pathological, or pharmacological challenges is key to our understanding of complex metabolic networks as these macronutrients also activate transcription fac ...

Caffeine consumption attenuates neurochemical modifications in the hippocampus of streptozotocin-induced diabetic rats

Rolf Gruetter, João Miguel das Neves Duarte

Type 1 diabetes can affect hippocampal function triggering cognitive impairment through unknown mechanisms. Caffeine consumption prevents hippocampal degeneration and memory dysfunction upon different insults and is also known to affect peripheral glucose ...
