Robust synchronization of coupled circadian and cell cycle oscillators in single mammalian cells

Felix Naef, Cédric Gobet, Kyle Gustafson, Jonathan Bieler, Rosamaria Cannavo

Circadian cycles and cell cycles are two fundamental periodic processes with a period in the range of 1 day. Consequently, coupling between such cycles can lead to synchronization. Here, we estimated the mutual interactions between the two oscillators by t ...

Kinetic Analysis of Transcriptional and Post-Transcriptional Processes During Circadian Cycles

Laura Symul

Every morning the sun rises, flooding the earth with its light and heat and every night it disappears leaving the Earth in the darkness of the night. Organisms living on this planet have adapted to this solar rhythm and have spread their activities through ...

Circadian rhythms in insect disease vectors

Antonio Carlos Alves Meireles Filho

Organisms from bacteria to humans have evolved under predictable daily environmental cycles owing to the Earth's rotation. This strong selection pressure has generated endogenous circadian clocks that regulate many aspects of behaviour, physiology and meta ...

The Circadian Clock Coordinates Ribosome Biogenesis

Felix Naef, Frédéric Bruno Martin Gachon, Laura Symul, Florian Atger, Celine Jouffe

Biological rhythms play a fundamental role in the physiology and behavior of most living organisms. Rhythmic circadian expression of clock-controlled genes is orchestrated by a molecular clock that relies on interconnected negative feedback loops of transc ...

Circadian Clock Characteristics Are Altered in Human Thyroid Malignant Nodules

Daniel Sage, Daniel Andreas Schmitter, Olivia Mariani

Context: The circadian clock represents the body's molecular time-keeping system. Recent findings revealed strong changes of clock gene expression in various types of human cancers. Objective: Due to emerging evidence on the connection between the circadia ...

Significance of View Direction in Simulating Circadian Potential of Architectural Spaces

Sharon Jane Gochenour

This research paper aims to simplify the question of how to take human movement into account when assessing the lighting conditions of a space. For a person working at a desk throughout the day doing paper-based or screen-based tasks, if it is assumed that ...

Analysis of precision in chemical oscillators: implications for circadian clocks

Felix Naef, Alessandro De Simone, Thomas d'Eysmond

Biochemical reaction networks often exhibit spontaneous self-sustained oscillations. An example is the circadian oscillator that lies at the heart of daily rhythms in behavior and physiology in most organisms including humans. While the period of these osc ...

Autonomous and self-sustained circadian oscillators displayed in human islet cells

Michaël Unser, Daniel Sage, Christophe Bauer

Following on from the emerging importance of the pancreas circadian clock on islet function and the development of type 2 diabetes in rodent models, we aimed to examine circadian gene expression in human islets. The oscillator properties were assessed in i ...

Circadian Dbp Transcription Relies on Highly Dynamic BMAL1-CLOCK Interaction with E Boxes and Requires the Proteasome

Felix Naef, David Michael Suter

The transcription factors BMAL1 and CLOCK drive the circadian transcription of clock and clock-controlled genes, such as Dbp. To investigate the kinetics of BMAL1 binding to target genes in real time, we generated a cell line harboring tandem arrays of Dbp ...

Regulation of circadian behaviour and metabolism by REV-ERB-α and REV-ERB-β

Johan Auwerx, Xuan Zhao

The circadian clock acts at the genomic level to coordinate internal behavioural and physiological rhythms via the CLOCK-BMAL1 transcriptional heterodimer. Although the nuclear receptors REV-ERB-α and REV-ERB-β have been proposed to form an accessory feedb ...
