    • Alteration in mitochondrial Ca2+ uptake disrupts insulin signaling in hypertrophic cardiomyocytes 
      Gutiérrez, Tomás; Parra, Valentina; Troncoso, Rodrigo; Pennanen, Christian; Contreras Ferrat, Ariel Eduardo; Vásquez Trincado, César Alonso; Morales, Pablo E.; López Crisosto, Camila; Sotomayor Flores, Cristian Alejandro; Chiong Lay, Mario; Rothermel, Beverly A.; Lavandero González, Sergio (BioMed Central Ltd., 2014)
      © 2014 Gutierrez et al.; licensee BioMed Central Ltd. Background: Cardiac hypertrophy is characterized by alterations in both cardiac bioenergetics and insulin sensitivity. Insulin promotes glucose uptake by cardiomyocytes ...
    • 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 ...
    • 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 ...
    • The transcription factor MEF2C mediates cardiomyocyte hypertrophy induced by IGF-1 signaling 
      Muñoz, Juan Pablo; Collao, Andrés; Chiong Lay, Mario; Maldonado Vera, Carola Patricia; Adasme, Tatiana; Carrasco Alarcón, Loreto del Pilar; Ocaranza Osses, Paula; Bravo Méndez, Roberto; González, Leticia; Díaz Araya, Guillermo; Hidalgo Tapia, María Cecilia; Lavandero González, Sergio (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009-10-09)
      Myocyte enhancer factor 2C (MEF2C) plays an important role in cardiovascular development and is a key transcription factor for cardiac hypertrophy. Here, we describe MEF2C regulation by insulin-like growth factor-1 (IGF-1) ...
