    • 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 ...
    • Discrete stochastic graph dynamics for the nuclear architecture of mouse meiotic prophase spermatocytes 
      López Fenner, Julio; Maignan, Aude; Echahed, Rachid; Berríos, Soledad (Springer Verlag, 2017)
    • 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 ...
    • Native American gene flow into Polynesia predating Easter Island settlement 
      Ioannidis, Alexander G.; Blanco Portillo, Javier; Sandoval, Karla; Hagelberg, Erika; Miquel-Poblete, Juan Francisco; Moreno Mayar, J. Víctor; Rodríguez Rodríguez, Juan Esteban; Auckland, Kathryn; Parks, Tom; Robson, Kathryn; Hill, Adrian V. S.; Ávila Arcos, María C.; Sockell, Alexandra; Homburger, Julian R; Wojcik, Genevieve L.; Barnes, Kathleen C.; Herrera, Luisa M.; Berríos, Soledad; Acuña, Mónica; Llop, Elena; Eng, Celeste; Huntsman, Scott; Burchard, Esteban G.; Gignoux, Christopher R.; Cifuentes, Lucía O.; Verdugo Salgado, Ricardo; Moraga Vergara, Mauricio; Mentzer, Alexander J.; Bustamante, Carlos D.; Moreno Estrada, Andrés (Nature, 2020)
      The possibility of voyaging contact between prehistoric Polynesian and Native American populations has long intrigued researchers. Proponents have pointed to the existence of New World crops, such as the sweet potato and ...
    • Nucleolar expression and chromosomal associations in Robertsonian spermatocytes of Mus musculus domesticus 
      López-Moncada, Fernanda; Tapia, Daniel; Zuñiga, Nolberto; Ayarza, Eliana; López-Fenner, Julio; Redi, Carlo Alberto; Berríos, Soledad (MDPI AG, 2019)
      We studied and compared the nucleolar expression or nucleoli from specific bivalents in spermatocytes of the standard Mus musculus domesticus 2n=40, of Robertsonian (Rb) homozygotes 2n = 24 and heterozygotes 2n = 32. We ...
    • 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 ...
    • Synaptic configuration of quadrivalents and their association with the XY bivalent in spermatocytes of ... 
      Berríos, Soledad; Fernández Donoso, Raúl; Ayarza, Eliana (2017)
      BACKGROUND: The nuclear architecture of meiotic prophase spermatocytes is based on higher-order patterns of spatial associations among chromosomal domains and consequently is prone to modification by chromosomal rearrangements. ...
