    • Ca2+, autophagy and protein degradation: Thrown off balance in neurodegenerative disease 
      Vicencio, José Miguel; Lavandero González, Sergio; Szabadkai, Gyorgy (ELSEVIER, 2010)
      Substantial progress has been made throughout the last decades in the elucidation of the key players and mechanisms responsible for Ca2+ signal generation in both excitable and non-excitable cells. Importantly, these ...
    • The inositol 1,4,5-trisphosphate receptor regulates autophagy through its interaction with Beclin 1 
      Vicencio, José Miguel; Ortíz, C.; Criollo Céspedes, Alfredo; Jones, A. W. E.; Kepp, O.; Galluzzi, Lorenzo; Joza, N.; Vitale, I.; Morselli, E.; Tailler, M.; Castedo, M.; Maiuri, M. C.; Molgó, Jordi; Szabadkai, G.; Lavandero González, Sergio; Kroemer, Guido (NATURE PUBLISHING GROUP, 2009-07)
      The inositol 1,4,5-trisphosphate receptor (IP3R) is a major regulator of apoptotic signaling. Through interactions with members of the Bcl-2 family of proteins, it drives calcium (Ca2+) transients from the endoplasmic ...
    • The inositol trisphosphate receptor in the control of autophagy 
      Criollo Céspedes, Alfredo; Vicencio, José Miguel; Tasdemir, E.; Maiuri, M. C.; Lavandero González, Sergio; Kroemer, Guido (LANDES BIOSCIENCE, 2007-07)
      The second messenger myo-inositol-1,4,5-trisphosphate (IP3) acts on the IP3 receptor (IP3R), an IP3-activated Ca2+ channel of the endoplasmic reticulum (ER). The IP3R agonist IP3 inhibits starvation-induced autophagy. The ...
    • La actividad de metaloproteinasa-9 se asocia al estrés oxidativo en el síndrome coronario agudo 
      Bittner, Alex; Castro Gálvez, Pablo; Pérez, Osvaldo; Corbalán, Ramón; Alcaíno Olivares, Hernán Alejandro; Troncoso Cotal, Rodrigo Hernán; Chiong Lay, Mario; Díaz Araya, Guillermo; Vicencio, José Miguel; Moraga, Francisco; Zanolli, Diego; Winter, José L.; Zamorano, Juan J.; Lavandero González, Sergio (Sociedad Chilena de Cardiología y Cirugía Cardiovascular, 2006)
      La metaloproteinasa (MMPs) son enzimas proteolíticas que participan en la inestabilidad de la placa aterosclerótica. En cultivos celulares, la actividad de metaloproteinasas-2 y 9 (MMP-2 y MMP-9) aumenta en presencia de ...
    • New insights into IGF-1 signaling in the heart 
      Troncoso Cotal, Rodrigo Hernán; Ibarra, Cristián; Vicencio, José Miguel; Jaimovich Pérez, Enrique; Lavandero González, Sergio (Elsevier, 2014)
      Insulin-like growth factor 1 (IGF-1) signaling regulates contractility, metabolism, hypertrophy, autophagy, senescence, and apoptosis in the heart. IGF-1 deficiency is associated with an increased risk of cardiovascul ...
    • A novel dihydropyridine with 3-aryl meta-hydroxyl substitution blocks L-type calcium channels in rat cardiomyocytes 
      Galvis Pareja, David; Zapata Torres, Gerald; Hidalgo Tapia, Jorge; Ayala, Pedro; Pedrozo Cibils, Zully; Ibarra, Cristián; Díaz Araya, Guillermo; Hall, Andrew R.; Vicencio, José Miguel; Núñez Vergara, Luis; Lavandero González, Sergio (Elsevier, 2014)
      Rationale: Dihydropyridines are widely used for the treatment of several cardiac diseases due to their blocking activity on L-type Ca2+ channels and their renowned antioxidant properties. Methods: We synthesized six novel ...
    • Senescence, Apoptosis or Autophagy? 
      Vicencio, José Miguel; Galluzzi, Lorenzo; Tajeddine, Nicolás; Ortiz, Carla; Criollo Céspedes, Alfredo; Tasdemir, E.; Morselli, Eugenia; Ben Younes, Amena; Chiara Maiuri, María; Lavandero González, Sergio; Kroemer, Guido (S. Karger AG, 2008)
      Many features of aging result from the incapacity of cells to adapt to stress conditions. When damage accumulates irreversibly, mitotic cells from renewable tissues rely on either of two mechanisms to avoid replication. ...
