    • BAG3 regulates total MAP1LC3B protein levels through a translational but not transcriptional mechanism 

      Rodríguez, Andrea E.; López Crisosto, Camila; Peña Oyarzún, Daniel; Salas, Daniela; Parra A., Valentina; Quiroga, Clara; Morawe, Tobías; Chiong Lay, Mario; Behl, Christian; Lavandero González, Sergio (Taylor and Francis, 2016)
      Autophagy is mainly regulated by post-translational and lipid modifications of ATG proteins. In some scenarios, the induction of autophagy is accompanied by increased levels of certain ATG mRNAs such as MAP1LC3B/LC3B, ATG5 ...
    • IGF-1: Un factor de crecimiento con acciones cardiovasculares pleiotrópicas. 

      Contreras Ferrat, Ariel Eduardo; Aránguiz Urroz, Pablo Daniel; Díaz Elizondo, Jessica; Chiong Lay, Mario; Muñoz, Juan Pablo; Parra Ortíz, María Valentina; Ibarra, Cristián; Rojas Rivera, Diego; Troncoso Cotal, Rodrigo; Eisner, Verónica; Salas, Daniela; Rodríguez Villarroel, Andrea Elizabeth; Carrasco Alarcón, Loreto del Pilar; Díaz Araya, Guillermo; Lavandero González, Sergio (Sociedad Chilena de Cardiología y Cirugía Cardiovascular, 2006)
      El factor de crecimiento análogo a insulina tipo 1 (IGF-1) es un péptido relacionado estructural y funcionalmente con insulina que posee efectos mitogénicos y citoprotectores. Sus efectos biológicos dependen de la activación ...
    • Inflamación y disfunción endotelial en pacientes con insuficiencia cardiaca crónica 

      Greig, Douglas; Castro, Pablo; Gabrielli, Luigi A.; Miranda, Rodrigo; Verdejo, Hugo; Alcaíno Gálvez, Hernán Alejandro; Bustos, Carlos; Chiong Lay, Mario; Godoy, Iván; Mellado, Rose Marie; García Nannig, Lorena; Salas, Daniela; Vivar Sánchez, Raúl; Vukasovic Ramírez, José Luis; Concepción, Roberto; Díaz Araya, Guillermo (SOC MEDICA SANTIAGO, 2008-06)
      Background: In chronic heart failure (CHF), endothelial dysfunction (ED) is a consequence of an imbalance of vascular tone regulating substances. The relationship between ED and inflammation has not been fully investigated. ...

    • Iron induces protection and necrosis in cultured cardiomyocytes: Role of reactive oxygen species and nitric oxide 

      Muñoz, Juan Pablo; Chiong Lay, Mario; García Nannig, Lorena; Troncoso Cotal, Rodrigo Andrés; Toro, Barbra; Pedrozo Cibils, Zully; Díaz Elizondo, Jessica; Salas, Daniela; Parra Ortíz, María Valentina; Núñez González, Marco; Hidalgo Tapia, María Cecilia; Lavandero González, Sergio (ELSEVIER SCIENCE INC, 2010-02-15)
      We investigate here the role of reactive oxygen species and nitric oxide in iron-induced cardiomyocyte hypertrophy or cell death Cultured rat cardiomyocytes incubated with 20 mu M iron (added as FeCl3-Na nitrilotriacetate, ...
    • Regulatory volume decrease in cardiomyocytes is modulated by calcium influx and reactive oxygen species 

      Rojas Rivera, Andrés; Díaz Elizondo, Jessica; Parra Ortíz, María Valentina; Salas, Daniela; Contreras Ferrat, Ariel Eduardo; Toro, Barbra; Chiong Lay, Mario; Olea Azar, Claudio; Lavandero González, Sergio (ELSEVIER SCIENCE BV, 2009-11-03)
      We investigated the role of Ca2+ in generating reactive oxygen species (ROS) induced by hyposmotic stress (Hypo) and its relationship to regulatory volume decrease (RVD) in cardiomyocytes. Hypo-induced increases in cytoplasmic ...
    • Role of Akt and Ca2+ on cell permeabilization via connexin43 hemichannels induced by metabolic inhibition 

      Salas, Daniela; Puebla, Carlos; Lampe, Paul D.; Lavandero González, Sergio; Sáez, Juan Carlos (Elsevier, 2015)
      © 2015 Elsevier B.V. Connexin hemichannels are regulated under physiological and pathological conditions. Metabolic inhibition, a model of ischemia, promotes surface hemichannel activation associated, in part, with increased ...
    • Serum uric acid correlates with extracellular superoxide dismutase activity in patients with chronic heart failure 

      Alcaíno Gálvez, Hernán Alejandro; Greig, Douglas; Chiong Lay, Mario; Verdejo, Hugo; Miranda, Rodrigo; Concepción, Roberto; Vukasovic Ramírez, José Luis; Díaz Araya, Guillermo; Mellado, Rose Marie; García Nannig, Lorena; Salas, Daniela; González, Leticia; Godoy, Iván; Castro, Pablo; Lavandero González, Sergio (ELSEVIER, 2008-07)
      Increased serum uric acid has been identified as an independent risk factor for cardiovascular disease. However, because of its antioxidant capacity, uric acid may play a beneficial role in endothelial function. This ...
