    • 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 ...
    • 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 failure in cyclin A1-deficient mouse spermatocytes triggers apoptosis through intrinsic and extrinsic ...

    • 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 ...
