Systems Chronobiology: Global Analysis of Gene Regulation in a 24-Hour Periodic World

Felix Naef, Jake Yeung, Jérôme Mermet

Mammals have evolved an internal timing system, the circadian clock, which synchronizes physiology and behavior to the daily light and dark cycles of the Earth. The master clock, located in the suprachiasmatic nucleus (SCN) of the brain, takes fluctuating ...

Rhythmic and clock-dependent chromatin loops regulate circadian gene expression

Jérôme Mermet

In mammals the circadian clock drives daily behavioural and physiological changes that resonate with environmental cues, which can be observed, for example, in the intricate timing of rest during the night and activity during the day in humans. The circadi ...

The genomic landscape of human cellular circadian variation points to a novel role for the signalosome

Frédéric Bruno Martin Gachon, Konstantin Popadin, Daniel Alain Dominique Marie Mauvoisin

The importance of natural gene expression variation for human behavior is undisputed, but its impact on circadian physiology remains mostly unexplored. Using umbilical cord fibroblasts, we have determined by genome-wide association how common genetic varia ...

Nuclear Proteomics Uncovers Diurnal Regulatory Landscapes in Mouse Liver

Felix Naef, Loïc Dayon, Jingkui Wang, Frédéric Bruno Martin Gachon, Martin Kussmann, Daniel Alain Dominique Marie Mauvoisin, Florian Atger, Federico Sizzano

Diurnal oscillations of gene expression controlled by the circadian clock and its connected feeding rhythm enable organisms to coordinate their physiologies with daily environmental cycles. While available techniques yielded crucial insights into regulatio ...

Transcriptional regulatory logic of the diurnal cycle in the mouse liver

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

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 ...

PDF Signaling Is an Integral Part of the Drosophila Circadian Molecular Oscillator

Bart Deplancke, Jean-Daniel Feuz

Circadian clocks generate 24-hr rhythms in physiology and behavior. Despite numerous studies, it is still uncertain how circadian rhythms emerge from their molecular and neural constituents. Here, we demonstrate a tight connection between the molecular and ...

Extensive Regulation of Diurnal Transcription and Metabolism by Glucocorticoids

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

Temperature regulates splicing efficiency of the cold-inducible RNA-binding protein gene Cirbp

Felix Naef, Saeed Omidi Klishami

In mammals, body temperature fluctuates diurnally around a mean value of 36 degrees C-37 degrees C. Despite the small differences between minimal and maximal values, body temperature rhythms can drive robust cycles in gene expression in cultured cells and, ...

Persistence, period and precision of autonomous cellular oscillators from the zebrafish segmentation clock

Andrew Charles Oates

In vertebrate development, the sequential and rhythmic segmentation of the body axis is regulated by a "segmentation clock". This clock is comprised of a population of coordinated oscillating cells that together produce rhythmic gene expression patterns in ...

Parvalbumin-Expressing GABAergic Neurons in Mouse Barrel Cortex Contribute to Gating a Goal-Directed Sensorimotor Transformation

Carl Petersen, Shankar Sachidhanandam, Berat Semihcan Sermet

Sensory processing in neocortex is primarily driven by glutamatergic excitation, which is counterbalanced by GABAergic inhibition, mediated by a diversity of largely local inhibitory interneurons. Here, we trained mice to lick a reward spout in response to ...

Sustained Sleep Fragmentation Induces Sleep Homeostasis in Mice

Pierre Magistretti, Jean-Marie Petit, Maxime Olivier Baud

Study Objectives: Sleep fragmentation (SF) is an integral feature of sleep apnea and other prevalent sleep disorders. Although the effect of repetitive arousals on cognitive performance is well documented, the effects of long-term SF on electroencephalogra ...
