    • Basal autophagy protects cardiomyocytes from doxorubicin-induced toxicity 
      Pizarro, Marcela; Troncoso Cotal, Rodrigo; Martínez, Gonzalo J.; Chiong Lay, Mario; Castro, Pablo F.; Lavandero González, Sergio (Elsevier, 2016)
      Doxorubicin (Doxo) is one of the most effective anti-neoplastic agents but its cardiotoxicity has been an important clinical limitation. The major mechanism of Doxo-induced cardiotoxicity is associated to its oxidative ...
    • Cardiovascular autophagy concepts, controversies, and perspectives 
      Lavandero González, Sergio; Troncoso Cotal, Rodrigo; Rotherme, Beverly; Martinet, Wim; Sadoshima, Junichi; Hill, Joseph (Taylor and Francis Inc., 2013)
      Despite recent scientific and technological advances, cardiovascular disease remains the leading cause of morbidity and mortality worldwide. Autophagy, an evolutionarily ancient response to cellular stress, has been ...
    • Hyperosmotic stress-dependent NFκB activation is regulated by reactive oxygen species and IGF-1 in cultured ... 
      Eisner, Verónica; Criollo Céspedes, Alfredo; Quiroga, Clara; Olea Azar, Claudio; Santibañez, Juan Francisco; Troncoso, Rodrigo; Chiong Lay, Mario; Díaz Araya, Guillermo; Foncea, Rocío; Lavandero González, Sergio (2006)
      We have recently shown that hyperosmotic stress activates p65/RelB NFκB in cultured cardiomyocytes with dichotomic actions on caspase activation and cell death. It remains unexplored how NFκB is regulated in cultured rat ...
    • Mitochondria, myocardial remodeling, and cardiovascular disease 
      Verdejo, Hugo; Campo, Andrea del; Troncoso, Rodrigo; Gutiérrez, Tomás; Toro, Barbra; Quiroga, Clara; Pedrozo Cibils, Zully; Muñoz, Juan; García Nannig, Lorena; Castro, Pablo; Lavandero González, Sergio (2012)
      The process of muscle remodeling lies at the core of most cardiovascular diseases. Cardiac adaptation to pressure or volume overload is associated with a complex molecular change in cardiomyocytes which leads to anatomic ...
    • Parallel activation of Ca2+-induced survival and death pathways in cardiomyocytes by sorbitol-induced ... 
      Chiong Lay, Mario; Parra, V.; Eisner, V.; Ibarra, C.; Maldonado, C.; Criollo Céspedes, Alfredo; Bravo, R.; Quiroga, C.; Contreras, A.; Vicencio Bustamante, José; Cea, P.; Bucarey, J.; Molgó, Jordi; Jaimovich Pérez, Enrique; Hidalgo Tapia, María Cecilia; Kroemer, G.; Lavandero González, Sergio (2010)
      Hyperosmotic stress promotes rapid and pronounced apoptosis in cultured cardiomyocytes. Here, we investigated if Ca2+ signals contribute to this response. Exposure of cardiomyocytes to sorbitol [600 mosmol (kg water)(-1)] ...
    • Polycystin-1 regulates cardiomyocyte mitophagy 
      Ramírez Sagredo, Andrea Soledad; Quiroga, Clara; Garrido Moreno, Valeria Soraya; López Crisosto, Camila; Leiva Navarrete, Sebastián Rolando; Norambuena Soto, Ignacio Estebán; Ortiz Quintero, Jose Jafet; Díaz Vesga, Magda C.; Pérez, William; Hendrickson, Troy; Parra Ortiz, Valentina Maria; Pedrozo Cibils, Zully Rocio Evangelina; Altamirano, Francisco; Chiong Lay, Mario Martin; Lavandero Gonzalez, Sergio Alejandro (Wiley, 2021)
      Polycystin-1 (PC1) is a transmembrane protein found in different cell types, including cardiomyocytes. Alterations in PC1 expression have been linked to mitochondrial damage in renal tubule cells and in patients with ...
    • Regulation of cardiomyocyte autophagy by calcium 
      Shaikh, Soni; Troncoso Cotal, Rodrigo; Criollo Céspedes, Alfredo; Bravo Sagua, Roberto; García Nannig, Lorena; Morselli, Eugenia; Cifuentes, Mariana; Quest, Andrew F. G.; Hill, Joseph A.; Lavandero González, Sergio (Amer Physiological Soc, 2016)
      Calcium signaling plays a crucial role in a multitude of events within the cardiomyocyte, including cell cycle control, growth, apoptosis, and autophagy. With respect to calcium-dependent regulation of autophagy, ion ...
