    • A high incidence of meiotic silencing of unsynapsed chromatin is not associated with substantial pachytene ... 
      Manterola, Marcia; Page, Jesús; Vasco, Chiara; Berríos, Soledad; Parra, María Teresa; Viera, Alberto; Rufas, Julio S.; Zuccotti, Maurizio; Garagna, Silvia; Fernández Donoso, Raúl (2009)
      Meiosis is a complex type of cell division that involves homologous chromosome pairing, synapsis, recombination, and segregation. When any of these processes is altered, cellular checkpoints arrest meiosis progression and ...
    • Aneuploidy in spermatids of Robertsonian (Rb) chromosome heterozygous mice 
      Manieu, Catalina; González, Marisel; López-Fenner, Julio; Page, Jesús; Ayarza, Eliana; Fernández Donoso, Raúl; Berríos, Soledad (Kluwer Academic Publishers, 2014)
      © 2014, The Author(s). Rb translocations are chromosomal rearrangements frequently found in natural populations of the house mouse Mus musculus domesticus. The standard diploid karyotype of the house mouse consisting of ...
    • Expression and behaviour of CENP-E at kinetochores during mouse spermatogenesis 
      Parra, María T.; Page, Jesús; Yen, Tim J.; He, Dacheng; Valdeolmillos, Ana; Rufas, Julio S.; Suja, José A. (2002)
      Centromere protein E (CENP-E) is a microtubule motor protein localised in the outer kinetochore plate and in the fibrous corona that relocalises to the midzone in early anaphase. While its expression in somatic cells has ...
    • Inactivation or non-reactivation: What accounts better for the silence of sex chromosomes during mammalian ... 
      Page, Jesús; De La Fuente, Roberto; Manterola, Marcia; Parra, María Teresa; Viera, Alberto; Berríos, Soledad; Fernández-Donoso, Raúl; Rufas, Julio S. (2012)
      During the first meiotic prophase in male mammals, sex chromosomes undergo a program of transcriptional silencing called meiotic sex chromosome inactivation (MSCI). MSCI is triggered by accumulation of proteins like BRCA1, ...
    • Meiotic behavior of a complex hexavalent in heterozygous mice for Robertsonian translocations: insights for ... 
      Ribagorda, Marta; Berríos, Soledad; Solano, Emanuela; Ayarza, Eliana; Martín-Ruiz, Marta; Gil-Fernández, Ana; Parra, María Teresa; Viera, Alberto; Rufas, Julio S.; Capanna, Ernesto; Castiglia, Riccardo; Fernández-Donoso, Raúl; Page, Jesús (Springer Science and Business Media Deutschland GmbH, 2019)
      Natural populations of the house mouse Mus musculus domesticus show great diversity in chromosomal number due to the presence of chromosomal rearrangements, mainly Robertsonian translocations. Breeding between two populations ...
    • Model of chromosome associations in mus domesticus spermatocytes 
      Berríos, Soledad; Manterola, Marcia; Prieto, Zulita; López Fenner, Julio; Page, Jesús; Fernández Donoso, Raúl (Society of Biology of Chile, 2010)
      Understanding the spatial organization of the chromosomes in meiotic nuclei is crucial to our knowledge of the genome's functional regulation, stability and evolution. This study examined the nuclear architecture of Mus ...
    • Number and nuclear localisation of nucleoli in mammalian spermatocytes 
      Berríos, Soledad; Fernández Donoso, Raúl; Pincheira, Juana; Page, Jesús; Manterola, Marcia; Cristina Cerda, Marcia (2004)
      In seven mammalian species, including man, the position and number of nucleoli in pachytene spermatocyte nuclei were studied from electron microscope (EM) nuclear sections or bivalent microspreads. The number and position ...
    • The pairing of X and Y chromosomes during meiotic prophase in the marsupial species Thylamys elegans is ... 
      Page, Jesús; Berríos, Soledad; Rufas, Julio S.; Parra, M. Teresa; Suja, José Á; Heyting, Christa; Fernández-Donoso, Raúl (2003)
      Unlike eutherian males, pairing of the sex chromosomes in marsupial males during the first meiotic prophase is not mediated by a synaptonemal complex. Instead, a specific structure, the dense plate, develops during pachytene ...
