Whole genome doubling promotes tumorigenesis through loss of chromatin segregation and compartment repositioning
Whole genome doubling (WGD) events are drivers of genetic innovation across vertebrate evolution. While generally detrimental to mammalian organisms, WGDs are crucial in the development of various plants and fungi, as well as for the terminal differentiati ...
EPFL2023Deciphering the molecular events leading to the global restoration of the chromatin landscape during mitotic exit
Two fundamental properties of embryonic stem cells (ESCs) are their ability to self-renew and differentiate into all somatic cell types. Maintenance of their identity faces major challenges when transitioning through mitosis, as most DNA-binding proteins a ...
EPFL2023Regulation and impact of TERRA R-loops at human telomeres
Telomeres are the nucleoprotein structures found at the ends of linear chromosomes. They ensure that the termini of chromosomes are not inappropriately recognized as sites of DNA damage, and are therefore crucial for genome stability. In spite of the heter ...
EPFL2023CENP-A and CENP-B collaborate to create an open centromeric chromatin state
Beat Fierz, Wei Cai, Harsh Nagpal
Centromeres are epigenetically defined via the presence of the histone H3 variant CENP-A. Contacting CENP-A nucleosomes, the constitutive centromere associated network (CCAN) and the kinetochore assemble, connecting the centromere to spindle microtubules d ...
Berlin2023Development of multiplexed single-molecule imaging techniques to study chromatin invasion dynamics of chromatin effector proteins
DNA-binding proteins physically interact with the DNA and directly affect genomic functions. The eukaryotic genome is compacted into chromatin, limiting the DNA access to nuclear factors. In this Ph.D. thesis, I explored the dynamic mechanisms, that allow ...
EPFL2023Telomere protection against oxidative stress
Telomeres are nucleoprotein structures at the ends of linear chromosomes, being essential for the maintenance of genomic integrity. Telomeres have a unique structure which distinguishes chromosome termini from DNA damage sites. Shelterin complexes are the ...
EPFL2023Substrates and Cyclic Peptide Inhibitors of the Oligonucleotide-Activated Sirtuin 7
The sirtuins are NAD+-dependent lysine deacylases, comprising seven isoforms (SIRT1-7) in humans, which are involved in the regulation of a plethora of biological processes, including gene expression and metabolism. The sirtuins share a common hydrolytic m ...
Weinheim2023Pan-cancer atlas of somatic core and linker histone mutations
Recent genomic data points to a growing role for somatic mutations altering core histone and linker histone-encoding genes in cancer. However, the prevalence and the clinical and biological implications of histone gene mutations in malignant tumors remain ...
2023Antagonistic interactions among structured domains in the multivalent Bicc1-ANKS3-ANKS6 protein network govern phase transitioning of target mRNAs
Daniel Constam, Benjamin Marcel Daniel Rothé, Céline Gagnieux, Simon Fortier, Céline Emmanuelle Schmuziger
The growing number of diseases linked to aberrant phase transitioning of ribonucleoproteins highlights the need to uncover how the interplay between multivalent protein and RNA interactions is regulated. Cytoplasmic granules of the RNA binding protein Bica ...
CELL PRESS2023Centriole elimination during Caenorhabditis elegans oogenesis initiates with loss of the central tube protein SAS-1
Pierre Gönczy, Coralie Busso, Alexander Woglar, Keshav Jha, Tamara Mikeladze-Dvali, Marie Juliette Ségolène Pierron
In most metazoans, centrioles are lost during oogenesis, ensuring that the zygote is endowed with the correct number of two centrioles, which are paternally contributed. How centriole architecture is dismantled during oogenesis is not understood. Here, we ...
