      Pérez, Paola; Aguilera, Sergio; Olea, Nancy; Alliende, Cecilia; Molina, Claudio; Brito, Mónica; Barrera, María José; Leyton Martínez, Cecilia; Rowzee, Anne; González Burgos, María Julieta (2010)
      Objectives. To analyse whether the alterations in the structure and organization of microvilli in salivary acinar cells from SS patients are linked to changes in the expression and/or cellular localization of ezrin. Methods. ...
    • Alterations in Type I Hemidesmosome Components Suggestive of Epigenetic Control in the Salivary Glands of ... 
      González, Sergio; Aguilera, Sergio; Alliende, Cecilia; Urzúa Tobar, Ulises; Quest, Andrew F. G.; Herrera Cisterna, Luisa; Molina, Claudio; Hermoso Ramello, Marcela; Ewert, Patricia; Brito, Mónica; Romo, Rafael; Leyton Martínez, Cecilia; Pérez, Paola; González Burgos, María Julieta (2011-04)
      Objective. Acinar cells in the salivary glands of patients with Sjo¨gren’s syndrome (SS) display severe alterations in anchorage to the basal lamina. Bioinformatics analysis of the BP230 gene sequence has revealed the ...
    • Changes in Rab3D Expression and Distribution in the Acini of Sjogren's Syndrome Patients Are Associated ... 
      Bahamondes, Verónica; Albornoz, Amelina; Aguilera, Sergio; Alliende, Cecilia; Molina, Claudio; Castro, Isabel; Urzúa Tobar, Ulises; Quest, Andrew F. G.; Barrera, María José; González, Sergio; Sánchez, Marianela; Härtel, Steffen; Hermoso Ramello, Marcela; Leyton Martínez, Cecilia; González Burgos, María Julieta (WILEY-BLACKWELL, 2011-10)
      Objective. Oral and ocular dryness are frequent and serious symptoms of Sjogren's syndrome (SS) that reflect problems in secretion due to glandular dysfunction. Exocytosis, an important process in the secretory pathway, ...
    • Decreased salivary sulphotransferase activity correlated with inflammation and autoimmunity parameters in ... 
      Castro, Isabel; Aguilera, Sergio; Brockhausen, Inka; Alliende, Cecilia; Quest, Andrew F. G.; Molina, Claudio; Urzúa Tobar, Ulises; Mandel, Ulla; Bahamondes, Verónica; Barrera, María José; Sánchez, Marianela; González, Sergio; Hermoso Ramello, Marcela; Leyton Martínez, Cecilia; González Burgos, María Julieta (Oxford University Press, 2012)
      Objectives. To determine the expression and enzymatic activities of sulphotransferases involved in mucin hyposulphation in labial salivary glands (LSGs) from SS patients and to correlate sulphotransferase activity with ...
    • Increased acinar damage of salivary glands of patients with Sjogren's syndrome is paralleled by simultaneous ... 
      Pérez, Paola; Kwon, Yoon-Jeoung; Alliende, Cecilia; Leyton Campos, Lisette; Aguilera, Sergio; Molina, Claudio; Labra, Cecilia; Julio, Marcelo; Leyton Martínez, Cecilia; González Burgos, María Julieta (WILEY-LISS, DIV JOHN WILEY & SONS INC, 2005-09)
      Objective. Previous findings in labial salivary glands (LSGs) from patients with Sjogren ' s syndrome (SS) suggest that increased activity and expression of matrix metalloproteinase 9 (MMP-9) and MMP-3 trigger the destruction ...
    • Mechanotransduction and epigenetic control in autoimmune diseases 
      González, Sergio; Aguilera, Sergio; Urzúa Tobar, Ulises; Quest, Andrew F. G.; Molina, Claudio; Alliende, Cecilia; Hermoso Ramello, Marcela; González Burgos, María Julieta (Elsevier, 2011)
      Differentiation of epithelial cells is required to define tissue architecture and appropriate function of these cells is associated with a specific pattern of gene expression. DNA methylation, post-translational modification ...
    • Pro-inflammatory cytokines enhance ERAD and ATF6 alpha pathway activity in salivary glands of Sjogren's ... 
      Barrera, María José; Aguilera, Sergio; Castro, Isabel; Cortés Araya, Juan Eliecer; Bahamondes Lorca, Verónica; Quest, Andrew F. G.; Molina, Claudio; González, Sergio; Hermoso Ramello, Marcela; Urzúa Tobar, Ulises; Leyton, Cecilia; González Burgos, María Julieta (Elsevier, 2016)
      Salivary gland (SG) acinar-cells are susceptible to endoplasmic reticulum (ER) stress related to their secretory activity and the complexity of synthesized secretory products. SGs of Sji5gren's syndrome patients (SS)-patients ...
    • Salivary mucins induce a Toll-like receptor 4-mediated pro-inflammatory response in human submandibular ...
