Cancer cells subvert the primate-specific KRAB zinc finger protein ZNF93 to control APOBEC3B

Didier Trono, Priscilla Turelli, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Julien Léonard Duc, Filipe Amândio Brandão Sanches Vong Martins, Charlène Mireille Raymonde Raclot, Cyril David Son-Tuyên Pulver, Olga Marie Louise Rosspopoff, Romain Forey

ZNF93 is a primate-restricted Krüppel-associated box zinc finger protein responsible for repressing 20- to 12-My-old L1 transposable elements. Here, we reveal that ZNF93 also regulates the key cancer driver APOBEC3B—a mutagenic enzyme linked to tumorigenes ...

Scan-based fusion proteins for modulating gene expression and methods of use

Didier Trono

The invention provides fusion protein comprising a SCAN domain bearing member of a zinc finger-containing protein, a fragment or variant thereof and a catalytically inactive RNA- guided endonuclease or a DNA adenine methyltransferase. Preferably, the fusio ...

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 ...

Pou5f1b inhibitors

Didier Trono, Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Sandra Eloise Kjeldsen, Laia Simo Riudalbas

The invention provides an agent modulating the expression and/or activity of i) the POU5F1B protein, a fragment or variant thereof, ii) an mRNA encoding POU5F1B, a fragment or variant thereof and/or iii) the POU5F1B gene. Preferably, the agent is for use i ...

A First-in-Human Randomized Study to Assess the Safety, Tolerability, Pharmacokinetics, and Neutralization Profile of Two Investigational Long-Acting Anti-SARS-CoV-2 Monoclonal Antibodies

Didier Trono, Norman Lionel Moullan

Introduction: COVID-19 remains a significant risk for the immunocompromised given their lower responsiveness to vaccination or infection. Therefore, passive immunity through long-acting monoclonal antibodies (mAbs) offers a needed approach for pre-exposure ...

Single-cell transcriptome analysis reveals atypical monocytes circulating ahead of acute graft-versus-host disease clinical onset

Didier Trono, Evaristo Jose Planet Letschert, Filipe Amândio Brandão Sanches Vong Martins

Acute graft-versus-host disease (aGVHD) represents the rejection of the recipient's skin, gut, and liver tissues of an allogeneic hematopoietic stem cell transplantation (HSCT) by the donor T cells. The onset of aGVHD is often rapid and its evolution is un ...

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 ...

A Cluster of Evolutionarily Recent KRAB Zinc Finger Proteins Protects Cancer Cells from Replicative Stress–Induced Inflammation

Didier Trono, Priscilla Turelli, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Filipe Amândio Brandão Sanches Vong Martins, Florian Huber, Cyril David Son-Tuyên Pulver, Olga Marie Louise Rosspopoff, Romain Forey, Joana Carlevaro Fita

Heterochromatin loss and genetic instability enhance cancer progression by favoring clonal diversity, yet uncontrolled replicative stress leads to mitotic catastrophe and inflammatory responses that promote immune rejection. KRAB domain-containing zinc fin ...

Ancestral genome reconstruction enhances transposable element annotation by identifying degenerate integrants

Didier Trono, Evaristo Jose Planet Letschert, Wayo Matsushima

Growing evidence indicates that transposable elements (TEs) play important roles in evolution by providing genomes with coding and non-coding sequences. Identification of TE-derived functional elements, however, has relied on TE annotations in individual s ...
