Naef lab – UPNAE Laboratory of Computational and Systems Biology

Our lab is interested in quantitative, systems biology, and more generally the link between physics and biology. We work on various problems including circadian rhythms, transcriptional bursting, developmental patterning, gene regulation, and single cell imaging. To study these systems we combine theoretical, computational and experimental methods.

Current Research Areas

> Circadian gene regulatory networks in mammals > Chronobiology of the liver > Circadian oscillators in single cells > Interactions of circadian oscilators and cell cycle > Transcriptional bursting and noise in mammalian gene transcription

How the circadian clock regulates liver genes in time and space

— EPFL scientists have carried out the first comprehensive study of how genes in the liver perform their metabolic functions in both space and time of day. Monitoring almost 5000 genes at the level of the individual cell across a 24-hour period, the researchers have modelled how the circadian clock and liver functions crosstalk throughout the day in sync with the feeding-fasting cycle.

HIGHLIGHTS

Space-time logic of liver gene expression at sub-lobular scale

31-03-2022

The mammalian liver is a central hub for systemic metabolic homeostasis. Liver tissue is spatially structured, with hepatocytes operating in repeating lobules, and sub-lobule zones performing distinct functions. The liver is also subject to extensive temporal regulation, orchestrated by the interplay of the circadian clock, systemic signals and feeding rhythms. However, liver zonation has previously (…)

The circadian oscillator analysed at the single-transcript level

31-03-2022

The circadian clock is an endogenous and self-sustained oscillator that anticipates daily environmental cycles. While rhythmic gene expression of circadian genes is well-described in populations of cells, the single-cell mRNA dynamics of multiple core clock genes remain largely unknown. Here we use single-molecule fluorescence in situ hybridisation (smFISH) at multiple time points to measure pairs (…)

Oscillating and stable genome topologies underlie hepatic physiological rhythms during the circadian cycle

31-03-2022

The circadian clock drives extensive temporal gene expression programs controlling daily changes in behavior and physiology. In mouse liver, transcription factors dynamics, chromatin modifications, and RNA Polymerase II (PolII) activity oscillate throughout the 24-hour (24h) day, regulating the rhythmic synthesis of thousands of transcripts. Also, 24h rhythms in gene promoter-enhancer chromatin looping accompany rhythmic mRNA (…)
