Take a walk on the KRAB side

Didier Trono, Olga Marie Louise Rosspopoff

Canonical Krüppel-associated box (KRAB)-containing zinc finger proteins (KZFPs) act as major repressors of transposable elements (TEs) via the KRAB-mediated recruitment of the heterochromatin scaffold KRAB-associated protein (KAP)1. KZFP genes emerged some ...

SARS-CoV-2 hijacks a cell damage response, which induces transcription of a more efficient Spike S-acyltransferase

Béatrice Kunz, Didier Trono, Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Audrey Geneviève Chuat, Francisco De Magalhães Sarmento R De Mesquita, Lucie Josepha Marie Bracq, Joana Carlevaro Fita, Nattawadee Panyain

SARS-CoV-2 infection requires Spike protein-mediated fusion between the viral and cellular membranes. The fusogenic activity of Spike depends on its post-translational lipid modification by host S-acyltransferases, predominantly ZDHHC20. Previous observati ...

Microfluidic characterisation reveals broad range of SARS-CoV-2 antibody affinity in human plasma

Didier Trono, Priscilla Turelli, Marc Emmenegger

The clinical outcome of SARS-CoV-2 infections, which can range from asymptomatic to lethal, is crucially shaped by the concentration of antiviral antibodies and by their affinity to their targets. However, the affinity of polyclonal antibody responses in p ...

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

Didier Trono, Shaoline Sheppard, Evaristo Jose Planet Letschert, 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 ...

Occupational risk of SARS-CoV-2 infection and reinfection during the second pandemic surge: a cohort study

Didier Trono

Objectives This cohort study including essential workers, assessed the risk and incidence of SARS-CoV-2 infection during the second surge of COVID-19 according to baseline serostatus and occupational sector. Methods Essential workers were selected from a s ...

Human reproduction is regulated by retrotransposons derived from ancient Hominidae-specific viral infections

Didier Trono, Julien Paul André Pontis, Yu Tao

The transcription factor network required for primordial germ cell (PGC) specification is known to diverge in mammals. Here the authors show that hominidae-specific transposable element (TE) LTR5Hs becomes transcriptionally active during PGC specification, ...

Primate-specific transposable elements shape transcriptional networks during human development

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

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-containing zinc finger protein and cancer

Didier Trono, Priscilla Turelli

The present invention provides methods for detecting cancer as well as agents and compositions for treating cancer by modulating the expression and/or activity of one or more i) KRAB-containing zinc finger protein (KZFP), ii) mRNA encoding a KZFP, and/or i ...

Transposon-activated POU5F1B promotes colorectal cancer growth and metastasis

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

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 ...

Patient-derived monoclonal antibody neutralizes SARS-CoV-2 Omicron variants and confers full protection in monkeys

Henning Paul-Julius Stahlberg, Didier Trono, Priscilla Turelli, Florence Pojer, Charlène Mireille Raymonde Raclot, Kelvin Ka Ching Lau, Dongchun Ni

The SARS-CoV-2 Omicron variant has very high levels of transmission, is resistant to neutralization by authorized therapeutic human monoclonal antibodies (mAb) and is less sensitive to vaccine-mediated immunity. To provide additional therapies against Omic ...

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

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

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 ...

A satellite DNA array barcodes chromosome 7 and regulates totipotency via ZFP819

Didier Trono, Helen Mary Rowe, Gabriela Ecco

Mammalian genomes are a battleground for genetic conflict between repetitive elements and KRAB-zinc finger proteins (KZFPs). We asked whether KZFPs can regulate cell fate by using ZFP819, which targets a satellite DNA array, ZP3AR. ZP3AR coats megabase reg ...

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