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 ...

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 ...

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 ...

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 ...

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 ...

The immunopeptidome landscape associated with T cell infiltration, inflammation and immune editing in lung cancer

Didier Trono, Evaristo Jose Planet Letschert, Laia Simo Riudalbas

One key barrier to improving efficacy of personalized cancer immunotherapies that are dependent on the tumor antigenic landscape remains patient stratification. Although patients with CD3+CD8+ T cell-inflamed tumors typically show better response to immune ...

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 ...

Transposable elements contribute to the spatiotemporal microRNA landscape in human brain development

Didier Trono, Evaristo Jose Planet Letschert, Shaoline Sheppard, Christopher James Playfoot

Transposable elements (TEs) contribute to the evolution of gene regulatory networks and are dynamically expressed throughout human brain development and disease. One gene regulatory mechanism influenced by TEs is the miRNA system of post-transcriptional co ...
