Mice with humanized livers reveal the role of hepatocyte clocks in rhythmic behavior

Cédric Gobet, Sylviane Métairon, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger

The synchronization of circadian clock depends on a central pacemaker located in the suprachiasmatic nuclei. However, the potential feedback of peripheral signals on the central clock remains poorly characterized. To explore whether peripheral organ circad ...

Comprehensive analysis of the circadian nuclear and cytoplasmic transcriptome in mouse liver

Felix Naef, Cédric Gobet, Clémence Yumie Syloun Hurni, Benjamin Dieter Weger

In eukaryotes, RNA is synthesised in the nucleus, spliced, and exported to the cytoplasm where it is translated and finally degraded. Any of these steps could be subject to temporal regulation during the circadian cycle, resulting in daily fluctuations of ...

Systematic analysis of differential rhythmic liver gene expression mediated by the circadian clock and feeding rhythms

Felix Naef, Cédric Gobet, Fabrice David, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger, Nicholas Edward Phillips

The circadian clock and feeding rhythms are both important regulators of rhythmic gene expression in the liver. To further dissect the respective contributions of feeding and the clock, we analyzed differential rhythmicity of liver tissue samples across se ...

Robust landscapes of ribosome dwell times and aminoacyl-tRNAs in response to nutrient stress in liver

Felix Naef, Cédric Gobet, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger, Nagammal Neelagandan

Translation depends on messenger RNA (mRNA)-specific initiation, elongation, and termination rates. While translation elongation is well studied in bacteria and yeast, less is known in higher eukaryotes. Here we combined ribosome and transfer RNA (tRNA) pr ...

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

Frédéric Bruno Martin Gachon, Benjamin Dieter Weger

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 ...

Circadian Regulation of Cochlear Sensitivity to Noise by Circulating Glucocorticoids

Frédéric Bruno Martin Gachon, Benjamin Dieter Weger

The cochlea possesses a robust circadian clock machinery that regulates auditory function. How the cochlear clock is influenced by the circadian system remains unknown. Here, we show that cochlear rhythms are system driven and require local Bmal1 as well a ...

The Mouse Microbiome Is Required for Sex-Specific Diurnal Rhythms of Gene Expression and Metabolism

Felix Naef, Cédric Gobet, Jake Yeung, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger

The circadian clock and associated feeding rhythms have a profound impact on metabolism and the gut microbiome. To what extent microbiota reciprocally affect daily rhythms of physiology in the host remains elusive. Here, we analyzed transcriptome and metab ...

Glucocorticoid deficiency causes transcriptional and post-transcriptional reprogramming of glutamine metabolism

Benjamin Dieter Weger, Meltem Weger

Background: Deficient glucocorticoid biosynthesis leading to adrenal insufficiency is life-threatening and is associated with significant co-morbidities. The affected pathways underlying the pathophysiology of co-morbidities due to glucocorticoid deficienc ...

Transcriptional regulatory logic of the diurnal cycle in the mouse liver

Felix Naef, Jonathan Aryeh Sobel, Guillaume Rey, Irina Krier, Nouria Hernandez, Bart Deplancke, Matteo Dal Peraro, Sunil Kumar Raghav, Frédéric Bruno Martin Gachon, Alexandra Styliani Kalantzi, Benjamin Dieter Weger

Many organisms exhibit temporal rhythms in gene expression that propel diurnal cycles in physiology. In the liver of mammals, these rhythms are controlled by transcription-translation feedback loops of the core circadian clock and by feeding-fasting cycles ...

Regulation of Mammalian Physiology by interconnected Circadian and Feeding Rhythms

Cédric Gobet, Florian Atger, Daniel Alain Dominique Marie Mauvoisin, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger

Circadian clocks are endogenous timekeeping systems that adapt in an anticipatory fashion the physiology and behavior of most living organisms. In mammals, the master pacemaker resides in the suprachiasmatic nucleus and entrains peripheral clocks using a w ...

Lipidomics reveals diurnal lipid oscillations in human skeletal muscle persisting in cellular myotubes cultured in vitro

Marc Moniatte, Howard Riezman, Jonathan Paz Montoya, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger

Circadian clocks play an important role in lipid homeostasis, with impact on various metabolic diseases. Due to the central role of skeletal muscle in whole-body metabolism, we aimed at studying muscle lipid profiles in a temporal manner. Moreover, it has ...

Stem cells and the circadian clock

Benjamin Dieter Weger, Meltem Weger

The circadian timing system is a complex biological network of interacting circadian clocks that regulates 24 h rhythms of behavioral and physiological processes. One intriguing observation is that stem cell homeostasis is subject to circadian clock regula ...

Extensive Regulation of Diurnal Transcription and Metabolism by Glucocorticoids

Cédric Gobet, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger, Meltem Weger

Altered daily patterns of hormone action are suspected to contribute to metabolic disease. It is poorly understood how the adrenal glucocorticoid hormones contribute to the coordination of daily global patterns of transcription and metabolism. Here, we exa ...

Circadian and feeding rhythms differentially affect rhythmic mRNA transcription and translation in mouse liver

Felix Naef, Patrick Descombes, Cédric Gobet, Jingkui Wang, Florian Atger, Frédéric Bruno Martin Gachon, Benjamin Dieter Weger

Diurnal oscillations of gene expression are a hallmark of rhythmic physiology across most living organisms. Such oscillations are controlled by the interplay between the circadian clock and feeding rhythms. Although rhythmic mRNA accumulation has been exte ...
