Evolutionarily recent transcription factors partake in human cell cycle regulation

Didier Trono, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Filipe Amândio Brandão Sanches Vong Martins, Charlène Mireille Raymonde Raclot, Alex Russell Lederer, Cyril David Son-Tuyên Pulver, Olga Marie Louise Rosspopoff, Romain Forey, Alexandre Coudray

The cell cycle is a fundamental process in eukaryotic biology and is accordingly controlled by a highly conserved core signaling cascade. However, whether recently evolved proteins also influence this process is unclear. Here, we systematically map the inf ...

Deconvolution of ex-vivo drug screening data and bulk tissue expression predicts the abundance and viability of cancer cell subpopulations

Alexandre Coudray

Ex-vivo drug sensitivity screening (DSS) allows the prediction of cancer treatment effectiveness in a personalized fashion. However, it only provides a readout on mixtures of cells, potentially occulting important information on clinically relevant cell su ...

Statistical learning quantifies transposable element-mediated cis-regulation

Didier Trono, Evaristo Jose Planet Letschert, Julien Léonard Duc, Cyril David Son-Tuyên Pulver, Alexandre Coudray, Julien Paul André Pontis, Delphine Yvette L Grun, Shaoline Sheppard, Raphaël Gérard Théodore Michel Marie de Deloÿe et Fourcade de Fondeville

Background: Transposable elements (TEs) have colonized the genomes of most metazoans, and many TE-embedded sequences function as cis-regulatory elements (CREs) for genes involved in a wide range of biological processes from early embryo- genesis to innate ...

Genetic features and genomic targets of human KRAB-zinc finger proteins

Didier Trono, Jacques Fellay, Priscilla Turelli, Christian Axel Wandall Thorball, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Julien Léonard Duc, Cyril David Son-Tuyên Pulver, Romain Forey, Bara Khubieh

Krüppel-associated box (KRAB) domain-containing zinc finger proteins (KZFPs) are one of the largest groups of transcription factors encoded by tetrapods, with 378 members in human alone. KZFP genes are often grouped in clusters reflecting amplification by ...

Transposon-activated POU5F1B promotes colorectal cancer growth and metastasis

Didier Trono, Laurence Gouzi Abrami, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Julien Léonard Duc, Laia Simo Riudalbas, Alexandre Coudray, Sagane Dind

The treatment of colorectal cancer (CRC) is an unmet medical need in absence of early diagnosis. Here, upon characterizing cancer-specific transposable element-driven transpochimeric gene transcripts (TcGTs) produced by this tumor in the SYSCOL cohort, we ...

KRAB zinc finger protein ZNF676 controls the transcriptional influence of LTR12-related endogenous retrovirus sequences

Didier Trono, Priscilla Turelli, Alexandre Louis André Persat, Julien Léonard Duc, Alexandre Coudray, Michaël Imbeault, Delphine Yvette L Grun, Tamara Rossy, Alexandra Iouranova, Jonas Caspar De Tribolet-Hardy

Background Transposable element-embedded regulatory sequences (TEeRS) and their KRAB-containing zinc finger protein (KZFP) controllers are increasingly recognized as modulators of gene expression. We aim to characterize the contribution of this system to g ...

Transposable elements and their KZFP controllers are drivers of transcriptional innovation in the developing human brain

Didier Trono, Evaristo Jose Planet Letschert, Julien Léonard Duc, Alexandre Coudray, Shaoline Sheppard, Sagane Dind, Christopher James Playfoot

Transposable elements (TEs) account for more than 50% of the human genome and many have been co-opted throughout evolution to provide regulatory functions for gene expression networks. Several lines of evidence suggest that these networks are fine-tuned by ...

Primate-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

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 ...

Endogenous retroviruses drive KRAB zinc-finger protein family expression for tumor suppression

Didier Trono, Priscilla Turelli, Alexandre Coudray

Gene expression aberration is a hallmark of cancers, but the mechanisms underlying such aberrations remain unclear. Human endogenous retroviruses (HERVs) are genomic repetitive elements that potentially function as enhancers. Since numerous HERVs are epige ...
