    • Cardiomyocyte ryanodine receptor degradation by chaperone-mediated autophagy 

      Pedrozo Cibils, Zully; Torrealba, Natalia; Fernández, Carolina; Gatica, Damián; Toro, Barbra; Quiroga, Clara; Rodríguez, Andrea E.; Sánchez, Gina; Gillette, Thomas G.; Hill, Joseph A.; Donoso Laurent, Paulina; Lavandero González, Sergio (the European Society of Cardiology, 2013)
      Aims Chaperone-mediated autophagy (CMA) is a selective mechanism for the degradation of soluble cytosolic proteins bearing the sequence KFERQ. These proteins are targeted by chaperones and delivered to lysosomes where ...
    • Dexamethasone-induced autophagy mediates muscle atrophy through mitochondrial clearance 

      Troncoso, Rodrigo; Paredes, Felipe; Parra, Valentina; Gatica, Damián; Vásquez Trincado, César Alonso; Quiroga, Clara; Bravo Sagua, Roberto; López Crisosto, Camila; Rodriguez, Andrea E.; Oyarzún, Alejandra P.; Kroemer, Guido; Lavandero González, Sergio (Taylor and Francis Inc., 2014)
      Glucocorticoids, such as dexamethasone, enhance protein breakdown via ubiquitin-proteasome system. However, the role of autophagy in organelle and protein turnover in the glucocorticoid-dependent atrophy program remains ...
    • Endoplasmic reticulum: ER stress regulates mitochondrial bioenergetics 

      Bravo Sagua, Roberto; Gutiérrez, Tomás; Paredes, Felipe; Gatica, Damián; Rodríguez, Andrea E.; Pedrozo Cibils, Zully; Chiong Lay, Mario; Parra, Valentina; Quest, Andrew F. G.; Rothermel, Beverly A.; Lavandero González, Sergio (Elsevier, 2012)
      Endoplasmic reticulum (ER) stress activates an adaptive unfolded protein response (UPR) that facilitates cellular repair, however, under prolonged ER stress, the UPR can ultimately trigger apoptosis thereby terminating damaged ...
    • Herp depletion protects from protein aggregation by up-regulating autophagy 

      Quiroga, Clara; Gatica, Damián; Paredes, Felipe; Bravo, Roberto; Troncoso, Rodrigo; Pedrozo Cibils, Zully; Rodríguez, Andrea E.; Toro, Barbra; Chiong Lay, Mario; Vicencio Bustamante, José Manuel; Hetz Flores, Claudio; Lavandero González, Sergio (Elsevier, 2013)
      Herp is an endoplasmic reticulum (ER) stress inducible protein that participates in the ER-associated protein degradation (ERAD) pathway. However, the contribution of Herp to other protein degradation pathways like autophagy ...
    • HERPUD1 protects against oxidative stress-induced apoptosis through downregulation of the inositol 1,4,5-trisphosphate receptor 

      Paredes, Felipe; Parra, Valentina; Torrealba, Natalia; Navarro Márquez, Mario F.; Gatica, Damián; Bravo Sagua, Roberto; Troncoso, Rodrigo; Pennanen, Christian; Quiroga, Clara; Chiong Lay, Mario; Caesar, Christa; Taylor, W. Robert; Molgó, Jordi; San Martín, Alejandra; Jaimovich Pérez, Enrique; Lavandero González, Sergio (Elsevier, 2016)
      Homocysteine-inducible, endoplasmic reticulum (ER) stress-inducible, ubiquitin-like domain member 1 (HERPUD1), an ER resident protein, is upregulated in response to ER stress and Ca2(+) homeostasis deregulation. HERPUD1 ...
    • Molecular mechanisms of autophagy in the cardiovascular system 

      Gatica, Damián; Chiong Lay, Mario; Lavandero González, Sergio; Klionsky, Daniel J. (Lippincott Williams and Wilkins, 2015)
      © 2015 American Heart Association, Inc. Autophagy is a catabolic recycling pathway triggered by various intra-or extracellular stimuli that is conserved from yeast to mammals. During autophagy, diverse cytosolic constituents ...
    • Regulation of autophagy by Insulin/IGF-1 signaling pathways 

      Troncoso, Rodrigo; Vásquez Trincado, César; Campo, Andrea del; Gatica, Damián; Morales, Pablo; Paredes, Felipe; Gutiérrez, Tomás; López Crisosto, Camila; Lavandero González, Sergio; Torrealba, Natalia; García Nannig, Lorena; Díaz Araya, Guillermo; Battiprolu, Pavan K.; Nemchenko, Andriy; Ferdous, Anwarul; Gillette, Thomas G.; Hill, Joseph A. (Nova Science Publishers, 2012)
