    • B regulates IS256-mediated Staphylococcus aureus biofilm phenotypic variation 

      Valle Turrillas, Jaione Upna; Vergara Irigaray, Marta Upna; Merino, Nekane; Penadés, José R.; Lasa Uzcudun, Íñigo Upna (American Society for Microbiology, 2007)   Artículo / Artikulua  OpenAccess
      Biofilm formation in Staphylococcus aureus is subject to phase variation, and biofilm-negative derivatives emerge sporadically from a biofilm-positive bacterial population. To date, the only known mechanism for generating ...
    • Base pairing interaction between 5′- and 3′-UTRs controls icaR mRNA translation in Staphylococcus aureus 

      Ruiz de los Mozos Aliaga, Igor Upna; Vergara Irigaray, Marta Upna; Segura, Víctor; Villanueva San Martín, Maite Upna; Bitarte, Nerea Upna; Saramago, Margarida; Domingues, Susana; Arraiano, Cecilia M.; Fechter, Pierre; Romby, Pascale; Valle Turrillas, Jaione Upna; Solano Goñi, Cristina Upna; Lasa Uzcudun, Íñigo Upna; Toledo Arana, Alejandro Upna (Public Library of Science, 2013)   Artículo / Artikulua  OpenAccess
      The presence of regulatory sequences in the 39 untranslated region (39-UTR) of eukaryotic mRNAs controlling RNA stability and translation efficiency is widely recognized. In contrast, the relevance of 39-UTRs in bacterial ...
    • Genome-wide antisense transcription drives mRNA processing in bacteria 

      Lasa Uzcudun, Íñigo Upna; Toledo Arana, Alejandro Upna; Dobin, Alexander; Villanueva San Martín, Maite Upna; Ruiz de los Mozos Aliaga, Igor Upna; Vergara Irigaray, Marta Upna; Segura, Víctor; Fagegaltier, Delphine; Penadés, José R.; Valle Turrillas, Jaione Upna; Solano Goñi, Cristina Upna; Gingeras, Thomas R. (National Academy of Sciences, 2011)   Artículo / Artikulua  OpenAccess
      RNA deep sequencing technologies are revealing unexpected levels of complexity in bacterial transcriptomes with the discovery of abundant noncoding RNAs, antisense RNAs, long 5′ and 3′ untranslated regions, and alternative ...
    • Protein A-mediated multicellular behavior in Staphylococcus aureus 

      Merino, Nekane; Toledo Arana, Alejandro Upna; Vergara Irigaray, Marta Upna; Valle Turrillas, Jaione Upna; Solano Goñi, Cristina Upna; Calvo, Enrique; Lopez, Juan Antonio; Foster, Timothy J.; Penadés, José R.; Lasa Uzcudun, Íñigo Upna (American Society for Microbiology, 2008)   Artículo / Artikulua  OpenAccess
      The capacity of Staphylococcus aureus to form biofilms on host tissues and implanted medical devices is one of the major virulence traits underlying persistent and chronic infections. The matrix in which S. aureus cells ...
    • The regulon of the RNA chaperone CspA and its auto-regulation in Staphylococcus aureus 

      Caballero Sánchez, Carlos; Menéndez Gil, Pilar; Catalán Moreno, Arancha; Vergara Irigaray, Marta Upna; García Martínez, Begoña Upna; Segura, Víctor; Irurzun Domínguez, Naiara; Villanueva San Martín, Maite Upna; Ruiz de los Mozos Aliaga, Igor Upna; Solano Goñi, Cristina Upna; Lasa Uzcudun, Íñigo Upna; Toledo Arana, Alejandro Upna (Oxford University Press, 2018)   Artículo / Artikulua  OpenAccess
      RNA-binding proteins (RBPs) are essential to finetune gene expression. RBPs containing the coldshock domain are RNA chaperones that have been extensively studied. However, the RNA targets and specific functions for ...
    • Relevant role of fibronectin-binding proteins in Staphylococcus aureus biofilm-associated foreign-body infections 

      Vergara Irigaray, Marta Upna; Valle Turrillas, Jaione Upna; Merino, Nekane; Latasa Osta, Cristina Upna; García Martínez, Begoña Upna; Ruiz de los Mozos Aliaga, Igor; Solano Goñi, Cristina Upna; Toledo Arana, Alejandro Upna; Penadés, José R.; Lasa Uzcudun, Íñigo Upna (American Society for Microbiology, 2009)   Artículo / Artikulua  OpenAccess
      Staphylococcus aureus can establish chronic infections on implanted medical devices due to its capacity to form biofilms. Analysis of the factors that assemble cells into a biofilm has revealed the occurrence of strains ...
    • Staphylococcus aureus develops an alternative, ica-independent biofilm in the absence of the arlRS two-component system 

      Toledo Arana, Alejandro Upna; Merino, Nekane; Vergara Irigaray, Marta Upna; Débarbouillé, Michel; Penadés, José R.; Lasa Uzcudun, Íñigo Upna (American Society for Microbiology, 2005)   Artículo / Artikulua  OpenAccess
      The biofilm formation capacity of Staphylococcus aureus clinical isolates is considered an important virulence factor for the establishment of chronic infections. Environmental conditions affect the biofilm formation capacity ...
