Hominoid-Specific Transposable Elements and KZFPs Facilitate Human Embryonic Genome Activation and Control Transcription in Naive Human ESCs

Didier Trono, Priscilla Turelli, Julien Léonard Duc, Sandra Eloise Kjeldsen, Julien Duc, Alexandre Coudray, Evaristo Jose Planet Letschert, Julien Paul André Pontis

Expansion of transposable elements (TEs) coincides with evolutionary shifts in gene expression. TEs frequently harbor binding sites for transcriptional regulators, thus enabling coordinated genome-wide activation of species- and context-specific gene expre ...

ZNF445 is a primary regulator of genomic imprinting

Didier Trono, Priscilla Turelli, Sandra Eloise Kjeldsen, Michaël Imbeault, Andrea Coluccio, Evaristo Jose Planet Letschert, Christian Axel Wandall Thorball

Genomic imprinting is an epigenetic process regulated by germline-derived DNA methylation, causing parental origin-specific monoallelic gene expression. Zinc finger protein 57 (ZFP57) is critical for maintenance of this epigenetic memory during post-fertil ...

The interactome of KRAB zinc finger proteins reveals the evolutionary history of their functional diversification

Didier Trono, Priscilla Turelli, Ruedi Aebersold, Julien Léonard Duc, Michaël Imbeault, Cécile Piot, Andrea Coluccio, Pierre-Yves Joseph Laurent Helleboid, Christian Axel Wandall Thorball, Julien Paul André Pontis

Krüppel‐associated box (KRAB)‐containing zinc finger proteins (KZFPs) are encoded in the hundreds by the genomes of higher vertebrates, and many act with the heterochromatin‐inducing KAP1 as repressors of transposable elements (TEs) during early embryogene ...

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 ...

KRAB-ZFPs and transposable elements rewire early human embryonic development transcriptional networks

Didier Trono, Priscilla Turelli, Julien Léonard Duc, Julien Duc, Alexandra Iouranova, Michaël Imbeault, Alexandre Coudray

MARY ANN LIEBERT, INC2018

DNA repair protein Rad18 restricts LINE-1 mobility

Priscilla Turelli

Long interspersed element-1 (LINE-1, L1) is a mobile genetic element comprising about 17% of the human genome. L1 utilizes an endonuclease to insert L1 cDNA into the target genomic DNA, which induces double-strand DNA breaks in the human genome and activat ...

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 ...

Loss of transcriptional control over endogenous retroelements during reprogramming to pluripotency

Didier Trono, Priscilla Turelli, Bastien Mangeat, Helen Mary Rowe, Marc Samuel Friedli, Adamantia Kapopoulou, Gabriela Ecco, Benjamin Rauwel, Carmen Maria Unzu Ezquerro, Evaristo Jose Planet Letschert

Endogenous retroelements (EREs) account for about half of the mouse or human genome, and their potential as insertional mutagens and transcriptional perturbators is suppressed by early embryonic epigenetic silencing. Here, we asked how ERE control is maint ...

The KRAB-ZFP/KAP1 System Contributes to the Early Embryonic Establishment of Site-Specific DNA Methylation Patterns Maintained during Development

Didier Trono, Priscilla Turelli, Karolina Bojkowska, Sandra Eloise Kjeldsen, Adamantia Kapopoulou, Charlène Mireille Raymonde Raclot

De novo DNA methylation is an essential aspect of the epigenetic reprogramming that takes place during early development, yet factors responsible for its instatement at particular genomic loci are poorly defined. Here, we demonstrate that the KRAB-ZFP-medi ...

Functional analysis and structural modeling of human APOBEC3G reveal the role of evolutionarily conserved elements in the inhibition of human immunodeficiency virus type 1 infection and Alu transposition

Olivier Michielin, Didier Trono, Priscilla Turelli, Bastien Mangeat

Retroelements are important evolutionary forces but can be deleterious if left uncontrolled. Members of the human APOBEC3 family of cytidine deaminases can inhibit a wide range of endogenous, as well as exogenous, retroelements. These enzymes are structura ...

APOBEC3-independent interferon-induced viral clearance in hepatitis B virus transgenic mice

Didier Trono, Priscilla Turelli, Bastien Mangeat, Stéphanie Jost, Sonia Verp

Interferon (IFN) has been part of the standard treatment of chronic hepatitis B infection for more than 2 decades, yet the mechanism of action of this antiviral remains poorly understood. It was recently observed that members of the human APOBEC family of ...

Induction of antiviral cytidine deaminases does not explain the inhibition of hepatitis B virus replication by interferons

Interfering residues narrow the spectrum of MLV restriction by human TRIM5alpha

Didier Trono, Priscilla Turelli, Pierre Maillard, Séverine Reynard

TRIM5alpha is a restriction factor that limits infection of human cells by so-called N- but not B- or NB-tropic strains of murine leukemia virus (MLV). Here, we performed a mutation-based functional analysis of TRIM5alpha-mediated MLV restriction. Our resu ...

DNA damage sensors ATM, ATR, DNA-PKcs, and PARP-1 are dispensable for human immunodeficiency virus type 1 integration

Didier Trono, Priscilla Turelli

Integration of a DNA copy of the viral RNA genome is a crucial step in the life cycle of human immunodeficiency virus type 1 (HIV-1) and other retroviruses. While the virally encoded integrase is key to this process, cellular factors yet to be characterize ...

Editing at the crossroad of innate and adaptive immunity

Didier Trono, Priscilla Turelli

Genetic information can be altered through the enzymatic modification of nucleotide sequences. This process, known as editing, was originally identified in the mitochondrial RNA of trypanosomes and later found to condition events as diverse as neurotransmi ...
