      Urra, Hery; Torres Gómez, Vicente; Ortiz, Rina J.; Lobos, Lorena; Díaz, María I.; Díaz, Natalia; Härtel, Steffen; Leyton Campos, Lisette; Quest, Andrew F. G. (PUBLIC LIBRARY SCIENCE, 2012-04-10)
      Caveolin-1 is known to promote cell migration, and increased caveolin-1 expression is associated with tumor progression and metastasis. In fibroblasts, caveolin-1 polarization and phosphorylation of tyrosine-14 are essential ...

      Rodríguez, Diego A.; Tapia, Julio; Fernández, Jaime G.; Torres Gómez, Vicente; Muñoz, Nicolás; Galleguillos, Daniela; Leyton Campos, Lisette; Quest, Andrew F. G. (2009)
      Augmented expression of cyclooxygenase-2 (COX-2) and enhanced production of prostaglandin E2 (PGE2) are associated with increased tumor cell survival and malignancy. Caveolin-1 is a scaffold protein that has been proposed ...
    • Ceramide-induced formation of ROS and ATP depletion trigger necrosis in lymphoid cells 
      Villena, Joan; Henríquez Luna, Mauricio; Torres Gómez, Vicente; Moraga, Francisco; Díaz Elizondo, Jessica; Arredondo, Cristian; Chiong Lay, Mario; Olea Azar, Claudio; Stutzin Schottlander, Andrés; Lavandero González, Sergio; Quest, Andrew F. G. (ELSEVIER SCIENCE INC, 2008-03-15)
      In lymphocytes, Fas activation leads to both apoptosis and necrosis, whereby the latter form of cell death is linked to delayed production of endogenous ceramide and is mimicked by exogenous administration of long- and ...
    • Extracellular matrix-specific Caveolin-1 phosphorylation on tyrosine 14 is linked to augmented melanoma ... 
      Ortiz, Rina; Díaz Jara, Jorge; Díaz, Natalia; Lobos González, Lorena; Cárdenas, Areli; Contreras, Pamela; Díaz, María Inés; Otte, Ellen; Cooper- White, Justin; Torres Gómez, Vicente; Leyton Campos, Lisette; Quest, Andrew F. G. (Impact Journals LLC, 2016)
      Caveolin-1 (CAV1) is a scaffolding protein that plays a dual role in cancer. In advanced stages of this disease, CAV1 expression in tumor cells is associated with enhanced metastatic potential, while, at earlier stages, ...
    • Nuclear accumulation of beta-catenin is associated with endosomal sequestration of the destruction complex ... 
      Reyes Rojas, Montserrat; Peña Oyarzún, Daniel; Silva, Patricio; Venegas, Sebastián; Criollo Céspedes, Alfredo; Torres Gómez, Vicente (Wiley, 2020)
      Potentially malignant lesions, commonly referred to as dysplasia, are associated with malignant transformation by mechanisms that remain unclear. We recently reported that increased Wnt secretion promotes the nuclear ...
    • Nuclear localization of β-catenin and expression of target genes are associated with increased Wnt secretion ... 
      Reyes Rojas, Montserrat; Peña Oyarzún, Daniel; Maturana Ramírez, Andrea; Torres Gómez, Vicente (Elsevier, 2019)
      Objectives: To evaluate the localization of β-catenin in oral dysplastic cells, the expression of target genes upregulated in oral dysplasia, and the role of Wnt ligands in these events. Materials and methods: Subcellular ...
    • PKD2/polycystin-2 induces autophagy by forming a complex with BECN1 
      Peña Oyarzún, Daniel; Rodríguez Peña, Marcelo; Burgos Bravo, Francesca; Vergara, Ángelo; Kretschmar Montecinos, Catalina; Sotomayor Flores, Cristián; Ramírez Sarmiento, César A.; De Smedt, Humbert; Reyes Rojas, Montserrat; Pérez, William; Torres Gómez, Vicente; Morselli, Eugenia; Altamirano, Francisco; Wilson, Christian; Hill, Joseph A.; Lavandero González, Sergio; Criollo Céspedes, Alfredo (Taylor & Francis, 2020)
      Macroautophagy/autophagy is an intracellular process involved in the breakdown of macromolecules and organelles. Recent studies have shown that PKD2/PC2/TRPP2 (polycystin 2, transient receptor potential cation channel), a ...
    • Role of Autophagy in the Microenvironment of Oral Squamous Cell Carcinoma 
      Peña Oyarzún, Daniel; Reyes Rojas, Montserrat; Hernández Cáceres, María Paz; Kretschmar, Catalina; Morselli, Eugenia; Ramírez Sarmiento, César; Lavandero González, Sergio; Torres Gómez, Vicente; Criollo, Alfredo (Frontiers Media, 2020)
      Oral squamous cell carcinoma, the most common type of oral cancer, affects more than 275,000 people per year worldwide. Oral squamous cell carcinoma is very aggressive, as most patients die after 3 to 5 years post-diagnosis. ...
    • The non-receptor tyrosine phosphatase type 14 blocks caveolin-1- enhanced cancer cell metastasis
