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 ...

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 ...

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 ...
