Pharmacological induction of a progenitor state for the efficient expansion of primary human hepatocytes

Matthias Lütolf, Didier Trono, Nathalie Brandenberg, Marc Samuel Friedli, Marco Cassano, Carmen Maria Unzu Ezquerro, Evaristo Jose Planet Letschert

The liver is an organ with strong regenerative capacity, yet primary hepatocytes have a low amplification potential in vitro, a major limitation for the cell-based therapy of liver disorders and for ex vivo biological screens. Induced pluripotent stem cell ...

KAP1 facilitates reinstatement of heterochromatin after DNA replication

Didier Trono, Priscilla Turelli, Annamaria Kauzlaric, Julien Léonard Duc, Sandra Eloise Kjeldsen, Benjamin Rauwel, Andrea Coluccio, Suk Min Jang, Julien Paul André Pontis, Geneviève Almouzni

During cell division, maintenance of chromatin features from the parental genome requires their proper establishment on its newly synthetized copy. The loss of epigenetic marks within heterochromatin, typically enriched in repetitive elements, endangers ge ...

Individual retrotransposon integrants are differentially controlled by KZFP/KAP1-dependent histone methylation, DNA methylation and TET-mediated hydroxymethylation in naïve embryonic stem cells

Didier Trono, Priscilla Turelli, Julien Léonard Duc, Sandra Eloise Kjeldsen, Gabriela Ecco, Andrea Coluccio

BACKGROUND: The KZFP/KAP1 (KRAB zinc finger proteins/KRAB-associated protein 1) system plays a central role in repressing transposable elements (TEs) and maintaining parent-of-origin DNA methylation at imprinting control regions (ICRs) during the wave of g ...

Properties of LINE-1 proteins and repeat element expression in the context of amyotrophic lateral sclerosis

Didier Trono, Priscilla Turelli, Evaristo Jose Planet Letschert

BackgroundAmyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease involving loss of motor neurons and having no known cure and uncertain etiology. Several studies have drawn connections between altered retrotransposon expression and ALS. C ...

Polyphenic trait promotes liver cancer in a model of epigenetic instability

Didier Trono, Sandra Eloise Kjeldsen, Marco Cassano, Alessandra Piersigilli, Suk Min Jang, Evaristo Jose Planet Letschert

Hepatocellular carcinoma (HCC) represents the fifth most common form of cancer worldwide and carries a high mortality rate due to lack of effective treatment. Males are eight times more likely to develop HCC than females, an effect largely driven by sex ho ...

KRAB zinc finger proteins

Didier Trono, Gabriela Ecco, Michaël Imbeault

Kruppel-associated box domain zinc finger proteins (KRAB-ZFPs) are the largest family of transcriptional regulators in higher vertebrates. Characterized by an N-terminal KRAB domain and a C-terminal array of DNA-binding zinc fingers, they participate, toge ...

SMiLE-seq identifies binding motifs of single and dimeric transcription factors

Philipp Bucher, Didier Trono, Giovanna Ambrosini, Bart Deplancke, Romain Fernand Pietro Groux, Alina Isakova, Pernille Yde Rainer, Michaël Imbeault, Riccardo Dainese, Daniel Alpern

Resolving the DNA-binding specificities of transcription factors (TFs) is of critical value for understanding gene regulation. Here, we present a novel, semiautomated protein-DNA interaction characterization technology, selective microfluidics-based ligand ...

KRAB 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 ...

The mouse genome displays highly dynamic populations of KRAB-zinc finger protein genes and related genetic units

Didier Trono, Annamaria Kauzlaric, Julien Léonard Duc, Gabriela Ecco, Marco Cassano, Michaël Imbeault

KRAB-containing poly-zinc finger proteins (KZFPs) constitute the largest family of transcription factors encoded by mammalian genomes, and growing evidence indicates that they fulfill functions critical to both embryonic development and maintenance of adul ...

DUX-family transcription factors regulate zygotic genome activation in placental mammals

Didier Trono, Sonia Verp, Julien Léonard Duc, Andrea Coluccio, Alberto De Iaco, Evaristo Jose Planet Letschert

In animal embryos, transcription is mostly silent for several cell divisions, until the release of the first major wave of embryonic transcripts through so-called zygotic genome activation (ZGA). Maternally provided ZGA-triggering factors have been identif ...

Transposable Elements and Their KRAB-ZFP Controllers Regulate Gene Expression in Adult Tissues

Didier Trono, Priscilla Turelli, Annamaria Kauzlaric, Julien Léonard Duc, Helen Mary Rowe, Sandra Eloise Kjeldsen, Gabriela Ecco, Marco Cassano, Michaël Imbeault, Andrea Coluccio

KRAB-containing zinc finger proteins (KRAB-ZFPs) are early embryonic controllers of transposable elements (TEs), which they repress with their cofactor KAP1 through histone and DNA methylation, a process thought to result in irreversible silencing. Using a ...
