KRAB zinc finger protein-mediated control of transposon-embedded regulatory sequences from human germline to early embryos
Transposable elements (TEs), also called jumping genes, are genetic elements capable of changing their position within the genome of their host. They make up large fractions of genomes, including 45% of human DNA content, according to current estimates.

EPFL2021Roles of Epigenetic Dysregulation in Cancer Progression and Metastasis
Nearly all the cells of an organism share the same DNA sequence or genome, and yet they show different phenotypes and carry out different functions. This diversity is made possible by a verity of molecular modifications acting on the DNA sequence that coll ...
EPFL2020Primate-restricted KRAB zinc finger proteins and target retrotransposons control gene expression in human neurons
Didier Trono, Bart Deplancke, Priscilla Turelli, Christian Axel Wandall Thorball, Julien Léonard Duc, Charlène Mireille Raymonde Raclot, Alexandre Coudray, Julien Paul André Pontis, Delphine Yvette L Grun, Christopher James Playfoot, Evgeniia Pankevich
In the first days of embryogenesis, transposable element-embedded regulatory sequences (TEeRS) are silenced by Kruppel-associated box (KRAB) zinc finger proteins (KZFPs). Many TEeRS are subsequently co-opted in transcription networks, but how KZFPs influen ...
2020A Tale of Two Tumors: Unraveling the Complexities of Epigenetic Dysregulation in Cancer
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 ...
EPFL2019Integrated microfluidic tools for the characterization of protein/DNA interactions in vitro and in vivo
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 ...
EPFL2019The Detection of Early Epigenetic Inheritance of Mitochondrial Stress in C. Elegans with a Microfluidic Phenotyping Platform
Johan Auwerx, Martinus Gijs, Matteo Cornaglia, Hüseyin Baris Atakan
Fluctuations and deterioration in environmental conditions potentially have a phenotypic impact that extends over generations. Transgenerational epigenetics is the defined term for such intergenerational transient inheritance without an alteration in the D ...
2019KRAB zinc-finger proteins contribute to the evolution of gene regulatory networks
Didier Trono, Michaël Imbeault, Pierre-Yves Joseph Laurent Helleboid
The human genome encodes some 350 Kruppel-associated box (KRAB) domain-containing zinc-finger proteins (KZFPs), the products of a rapidly evolving gene family that has been traced back to early tetrapods(1,2). The function of most KZFPs is unknown, but a f ...
Nature Publishing Group2017Genomic targets and molecular partners of the chromatin regulator KAP1
KAP1 is an enigmatic regulatory protein, first described some twenty years ago, shown to be involved in multiple and diverse cellular functions. Specifically, it mediates tasks critical to cell growth and differentiation, pluripotency, apoptosis, gene sile ...
EPFL2017Unraveling the KRAB/KAP1 control of transposable elements in pluripotent and somatic cells
Transposable elements (TEs) are DNA sequences able to change position in the genome, and represent more than 40% of mammalian genetic material. TEs can have positive or detrimental effects on the host, being both important motors of evolution and genomic t ...
EPFL2016Transposable Elements, Polydactyl Proteins, and the Genesis of Human-Specific Transcription Networks
Transposable elements (TEs) may account for up to two-thirds of the human genome, and as genomic threats they are subjected to epigenetic control mechanisms engaged from the earliest stages of embryonic development. We previously determined that an importa ...
