    • Alterations in chromosomal synapses and DNA repair in apoptotic spermatocytes of Mus m. domesticus 
      Ayarza Ramírez, Gladys; González Vergara, Marisel; López, F.; Fernández Donoso, Raúl; Page, J.; Berríos del Solar, María Soledad (Pagepress, 2016)
      We investigated whether apoptotic spermatocytes from the mouse Mus m. domesticus presented alterations in chromosomal synapses and DNA repair. To enrich for apoptotic spermatocytes, the scrotum's temperature was raised by ...
    • Involvement of synaptonemal complex proteins in sex chromosome segregation during marsupial male meiosis 
      Page, Jesús; Viera, Alberto; Parra, María Teresa; Fuente, Roberto de la; Suja, José Angel; Prieto, Ignacio; Barbero, José Luis; Rufas, Julio S.; Berríos del Solar, María Soledad; Fernández Donoso, Raúl (PUBLIC LIBRARY SCIENCE, 2006-08)
      Marsupial sex chromosomes break the rule that recombination during first meiotic prophase is necessary to ensure reductional segregation during first meiotic division. It is widely accepted that in marsupials X and Y ...
    • The program of sex chromosome pairing in meiosis is highly conserved across marsupial species: Implications ... 
      Page, Jesús; Berríos del Solar, María Soledad; Parra, María Teresa; Viera, Alberto; Suja, José Angel; Prieto, Ignacio; Barbero, José Luis; Rufas, Julio S.; Fernández Donoso, Raúl (GENETICS, 2005-06)
      Marsupials present a series of genetic and chromosomal features that are highly conserved in very distant species. One of these features is the absence of a homologous region between X and Y chromosomes. According to this ...
    • Robertsonian chromosomes and the nuclear architecture of mouse meiotic prophase spermatocytes 
      Berríos del Solar, María Soledad; Manieu Seguel, Catalina; López Fenner, Julio; Ayarza Ramírez, Gladys; Page, Jesús; González Vergara, Marisel; Manterola Zúñiga, Marcia; Fernández Donoso, Raúl (BioMed Central, 2014)
      Background: The nuclear architecture of meiotic prophase spermatocytes is based on higher-order patterns of spatial associations among chromosomal domains from different bivalents. The meiotic nuclear architecture depends on ...
    • Robertsonian chromosomes and the nuclear architecture of mouse meiotic prophase spermatocytes 
      Berríos del Solar, María Soledad; Manieu Seguel, Catalina Paz; López Fenner, Julio; Ayarza Ramírez, Eliana; Page, Jesús; González Vergara, Marisel; Manterola Zúñiga, Marcia Carolina; Fernández Donoso, Raúl (BioMed Central, 2014)
      Background: The nuclear architecture of meiotic prophase spermatocytes is based on higher-order patterns of spatial associations among chromosomal domains from different bivalents. The meiotic nuclear architecture depends on ...
    • Sex chromosomes, synapsis, and cohesins: a complex affair 
      Page, Jesús; Fuente, Roberto de la; Gómez, Rocío; Calvente, Adela; Viera, Alberto; Parra, María Teresa; Santos, Juan Luis; Berríos del Solar, María Soledad; Fernández Donoso, Raúl; Suja, José Angel; Rufas, Julio S. (SPRINGER, 2006-06)
      During first meiotic prophase, homologous chromosomes are held together by the synaptonemal complex, a tripartite proteinaceous structure that extends along the entire length of meiotic bivalents. While this feature is ...
    • The frequency of heterologous synapsis increases with aging in Robertsonian heterozygous male mice 
      Vasco, Chiara; Manterola, Marcia; Page, Jesús; Zuccotti, Maurizio; Fuente, Roberto de la; Redi, Carlo Alberto; Fernández Donoso, Raúl; Garagna, Silvia (Springer, 2012-02)
      The house mouse is characterised by highly variable chromosome number due to the presence of Robertsonian (Rb) chromosomes. During meiosis in Rb heterozygotes, intricated chromosomal figures are produced, and many unsynapsed ...
