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

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

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 ...

Another Shp on the Horizon for Bile Acids

Kristina Schoonjans, Alessia Perino

Bile acid metabolism is tightly controlled due to the toxic effects of bile acid overload. In this issue, research from the Feng lab reports Shp2 as a novel integrator of hepatic bile acid and FGF15/FGF19 signaling, adding another layer of complexity to th ...

Circadian clock-dependent and -independent rhythmic proteomes implement distinct diurnal functions in mouse liver

Felix Naef, Jingkui Wang, Frédéric Bruno Martin Gachon, Daniel Alain Dominique Marie Mauvoisin, Florian Atger, Celine Jouffe

Diurnal oscillations of gene expression controlled by the circadian clock underlie rhythmic physiology across most living organisms. Although such rhythms have been extensively studied at the level of transcription and mRNA accumulation, little is known ab ...

The Receptor TGR5 Protects the Liver From Bile Acid Overload During Liver Regeneration in Mice

Kristina Schoonjans

Many regulatory pathways are involved in liver regeneration after partial hepatectomy (PH) to initiate growth, protect liver cells, and sustain functions of the remnant liver. Bile acids (BAs), whose levels rise in the blood early after PH, stimulate both ...

Improved lipid profiling of the mouse liver by 1H-NMR spectroscopy at 14.1T in vivo

Rolf Gruetter, Hongxia Lei, Ana Francisca Leal Silva Soares

Purpose/Introduction: Whole-body metabolic deregulation features changes in hepatic lipid dynamics. In vivo 1H-MRS allows to noninvasively assess hepatic lipid content (HLC) and composition both in humans [1] and rodents [2]. Transgenic mice provide insigh ...

Genome-Wide RNA Polymerase II Profiles and RNA Accumulation Reveal Kinetics of Transcription and Associated Epigenetic Changes During Diurnal Cycles

Olivier Martin, Bart Deplancke, Felix Naef, Jacques Rougemont, Laura Symul, Nicolas Jean Philippe Guex, Winship Herr, Mauro Delorenzi, Nouria Hernandez

Interactions of cell-autonomous circadian oscillators with diurnal cycles govern the temporal compartmentalization of cell physiology in mammals. To understand the transcriptional and epigenetic basis of diurnal rhythms in mouse liver genome-wide, we gener ...

Genome-Wide and Phase-Specific DNA-Binding Rhythms of BMAL1 Control Circadian Output Functions in Mouse Liver

Felix Naef, Guillaume Rey, Jacques Rougemont

The mammalian circadian clock uses interlocked negative feedback loops in which the heterodimeric basic helix-loop-helix transcription factor BMAL1/CLOCK is a master regulator. While there is prominent control of liver functions by the circadian clock, the ...

In Vivo Studies on the Control of Gene Expression and Protein Degradation

Karolina Bojkowska

Cellular homeostasis is maintained by tightly regulated gene networks, controlled notably at the levels of transcription, mRNA processing, and protein post-translational modification and turnover. This thesis focuses on two of these regulatory steps, namel ...
