Clusters of lineage-specific genes are anchored by ZNF274 in repressive perinucleolar compartments

Didier Trono, Sandra Eloise Kjeldsen, Julien Léonard Duc, Olga Marie Louise Rosspopoff, Delphine Yvette L Grun, Shaoline Sheppard

Long known as the site of ribosome biogenesis, the nucleolus is increasingly recognized for its role in shaping three-dimensional (3D) genome organization. Still, the mechanisms governing the targeting of selected regions of the genome to nucleolus-associa ...

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 ...

Primate-specific transposable elements shape transcriptional networks during human development

Didier Trono, Matthias Lütolf, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Julien Léonard Duc, Cyril David Son-Tuyên Pulver, Julien Paul André Pontis, Delphine Yvette L Grun, Christopher James Playfoot, Andrea Manfrin

The human genome harbors more than 4.5 million transposable element (TE)-derived insertions, the result of recurrent waves of invasion and internal propagation. Here they show that TEs belonging to evolutionarily recent subfamilies go on to regulate later ...

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 ...

Integrated proteogenomic deep sequencing and analytics accurately identify non-canonical peptides in tumor immunopeptidomes

Didier Trono, George Coukos, Marion Leleu, Evaristo Jose Planet Letschert, Markus Müller, Florian Huber, Laia Simo Riudalbas, Delphine Yvette L Grun, Ioannis Xenarios, Lin Zhang

Efforts to precisely identify tumor human leukocyte antigen (HLA) bound peptides capable of mediating T cell-based tumor rejection still face important challenges. Recent studies suggest that non-canonical tumor-specific HLA peptides derived from annotated ...

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 ...

DUX is a non-essential synchronizer of zygotic genome activation

Didier Trono, Sandra Eloise Kjeldsen, Sonia Verp, Delphine Yvette L Grun, Alberto De Iaco

Some of the earliest transcripts produced in fertilized human and mouse oocytes code for DUX, a double homeodomain protein that promotes embryonic genome activation (EGA). Deleting Dux by genome editing at the 1- to 2-cell stage in the mouse impairs EGA an ...

RasGRP1 is a potential biomarker for stratifying anti-EGFR therapy response in colorectal cancer

Mauro Delorenzi, Delphine Yvette L Grun

Colorectal cancer (CRC) is the third most frequent neoplastic disorder and is a main cause of tumor-related mortality, as many patients progress to stage IV metastatic CRC. Standard care consists of combination chemotherapy (FOLFIRI or FOLFOX). Patients wi ...
