  • Ancient genomic regulatory blocks are a source for regulatory gene deserts in vertebrates after whole-genome duplications
    Touceda-Suárez, María; Kita, Elizabeth M.; Acemel, Rafael D.; Firbas, Panos N.; Magri, Marta S.; Naranjo, Silvia; Tena, Juan J.; Gómez Skarmeta, José Luis; Maeso, Ignacio; Irimia, Manuel (Oxford University Press (OUP), 2020)
    We investigated how the two rounds of whole-genome duplication that occurred at the base of the vertebrate lineage have impacted ancient microsyntenic associations involving developmental regulators (known as genomic ...
  • Gene regulatory networks of epidermal and neural fate choice in a chordate
    Leon, Anthony; Subirana, Lucie; Magre, Kevin; Cases, Ildefonso; Tena, Juan J.; Irimia, Manuel; Gómez Skarmeta, José Luis; Escriva, Hector; Bertrand, Stéphanie (Oxford University Press, 2022)
    Neurons are a highly specialized cell type only found in metazoans. They can be scattered throughout the body or grouped together, forming ganglia or nerve cords. During embryogenesis, centralized nervous systems develop ...
  • Parallel evolution of amphioxus and vertebrate small-scale gene duplications
    Brasó-Vives, Marina, 1990-; Marlétaz, Ferdinand; Echchiki, Amina; Mantica, Federica; Acemel, Rafael D.; Gómez Skarmeta, José Luis; Hartasánchez Frenk, Diego Andrés, 1982-; Le Targa, Lorlane; Pontarotti, Pierre; Tena, Juan J.; Maeso, Ignacio; Escriva, Hector; Irimia, Manuel; Robinson-Rechavi, Marc (BioMed Central, 2022)
    Background: Amphioxus are non-vertebrate chordates characterized by a slow morphological and molecular evolution. They share the basic chordate body-plan and genome organization with vertebrates but lack their 2R whole-genome ...
  • The Dynamic Regulatory Genome of Capsaspora and the Origin of Animal Multicellularity
    Sebé-Pedrós, Arnau; Ballaré, Cecilia Julia; Parra-Acero, Helena; Chiva, Cristina; Tena, Juan J.; Sabidó Aguadé, Eduard, 1981-; Gómez Skarmeta, José Luis; Di Croce, Luciano; Ruíz Trillo, Iñaki (Elsevier, 2016)
    The unicellular ancestor of animals had a complex repertoire of genes linked to multicellular processes. This suggests that changes in the regulatory genome, rather than in gene innovation, were key to the origin of animals. ...
  • The repression of Atoh1 by neurogenin1 during inner ear development
    Gálvez García, Héctor, 1989-; Tena, Juan J.; Giráldez, Fernando; Abelló Sumpsi, Gina, 1980- (Frontiers, 2017)
    Atonal homolog 1 (Atoh1) and Neurogenin1 (Neurog1) are basic Helix-Loop-Helix (bHLH) transcription factors crucial for the generation of hair cells (HCs) and neurons in the inner ear. Both genes are induced early in ...
