Chromatin three-dimensional interactions mediate genetic effects on gene expression

David Hacker, Philipp Bucher, Giovanna Ambrosini, Aurélien Dominique Reymond

Studying the genetic basis of gene expression and chromatin organization is key to characterizing the effect of genetic variability on the function and structure of the human genome. Here we unravel how genetic variation perturbs gene regulation using a da ...

Chemical and biophysical methods to explore dynamic mechanisms of chromatin silencing

Beat Fierz, Iuliia Boichenko

Chromatin, the nucleoprotein complex organizing the genome, is central in regulating gene expression and genome organization. Chromatin conformational dynamics, controlled by histone post-translational modifications (PTM) and effector proteins, play a key ...

The role of OCT4 and SOX2 in regulating chromatin accessibility and cell fate across the cell cycle in embryonic stem cells

Torgil Elias Friman

Precise spatiotemporal regulation of gene expression is essential for development and homeostasis of complex organisms. This is achieved in large part by sequence-specific transcription factors (TF) that bind to genomic regulatory elements to activate or r ...

Mitotic chromosome binding predicts transcription factor properties in interphase

Mahé Cécile Raccaud

Mammalian transcription factors (TFs) differ broadly in their nuclear mobility and sequence-specific/non-specific DNA binding affinity. How these properties affect the ability of TFs to occupy their specific binding sites in the genome and modify the epige ...

Integrated microfluidic tools for the characterization of protein/DNA interactions in vitro and in vivo

Riccardo Dainese

The specific interaction between DNA and proteins constitutes one of the crucial elements in the regulation of gene expression. This thesis focuses on the development and optimization of two microfluidic-based technologies called SMiLE-seq and FloChIP that ...

A Tale of Two Tumors: Unraveling the Complexities of Epigenetic Dysregulation in Cancer

Maria Christine Donaldson

Epigenetics plays an important role in cancer development and progression. Cancer cells hijack the epigenome by modifying the histone protein units responsible for packaging DNA, or by modifying the DNA itself, resulting in changes to chromatin topology an ...

Dynamic protein-chromatin interactions in heterochromatin and during the DNA damage response on the single molecule level

Andreas Linus Bachmann

Dynamic regulation of chromatin, a structure consisting of DNA and histone proteins, is mediated through histone post-translational modifications (PTMs) and effector proteins. HP1a and PRC2 are recruited to repressive PTMs (H3K9me3, H3K27me3) and enable he ...

A bi-terminal protein ligation strategy to probe chromatin structure during DNA damage

Beat Fierz, Sinan Kilic, Iuliia Boichenko, Carolin Christine Lechner

The cellular response to DNA damage results in a signaling cascade that primes chromatin for repair. Combinatorial post-translational modifications (PTMs) play a key role in this process by altering the physical properties of chromatin and recruiting downs ...

Deciphering the chromatin binding mechanisms of human HP1 variants at the single-molecule level

Louise Catherine Bryan

In eukaryotic cells, DNA is tightly packed in the form chromatin. The basic structure of chromatin is a nucleosome composed of 147 bp DNA wrapped around eight histone proteins; two copies of H2A, H2B, H3 and H4. These histone proteins are decorated with pa ...

Nucleosome acidic patch-targeting binuclear ruthenium compounds induce aberrant chromatin condensation

Paul Joseph Dyson, Tina Riedel, Benjamin Samuel Murray

The 'acidic patch' is a highly electronegative cleft on the histone H2A-H2B dimer in the nucleosome. It is a fundamental motif for protein binding and chromatin dynamics, but the cellular impact of targeting this potentially therapeutic site with exogenous ...

Zika virus causes supernumerary foci with centriolar proteins and impaired spindle positioning

Pierre Gönczy, Coralie Busso, Benita Wolf

Zika virus (ZIKV) causes congenital microcephaly. Although ZIKV can impair cell cycle progression and provoke apoptosis, which probably contributes to disease aetiology through depletion of neural progenitor cells, additional cellular mechanisms may be imp ...

Centriole Biogenesis: From Identifying the Characters to Understanding the Plot

Pierre Gönczy, Niccolo Banterle

The centriole is a beautiful microtubule-based organelle that is critical for the proper execution of many fundamental cellular processes, including polarity, motility, and division. Centriole biogenesis, the making of this miniature architectural wonder, ...
