    • 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 ...
    • Angiotensin-(1–9) prevents cardiomyocyte hypertrophy by controlling mitochondrial dynamics via miR-129-3p/PKIA ... 
      Sotomayor Flores, Cristian; Rivera Mejías, Pablo; Vásquez Trincado, César; López Crisosto, Camila; Morales, Pablo E.; Pennanen, Christian; Polakovicova, Iva; Aliaga Tobar, Víctor; García Nannig, Lorena; Roa, Juan Carlos; Rothermel, Beverly A.; Maracaja Coutinho, Vinicius; Ho-Xuan, Hung; Meister, Gunter; Chiong, Mario; Ocaranza, María Paz; Corvalán, Alejandro H.; Parra Ortiz, Valentina; Lavandero González, Sergio (2020)
      Angiotensin-(1-9) is a peptide from the noncanonical renin-angiotensin system with anti-hypertrophic effects in cardiomyocytes via an unknown mechanism. In the present study we aimed to elucidate it, basing us initially ...
    • Drp1 loss-of-function reduces cardiomyocyte oxygen dependence protecting the heart from ischemia-reperfusion injury 
      Zepeda Iriarte, Ramiro; Kuzmicic, Jovan; Parra Ortiz, Valentina; Troncoso Cotal, Rodrigo; Pennanen, Christian; Riquelme, Jaime A.; Pedrozo Cibils, Zully; Chiong Lay, Mario; Sánchez, Gina; Lavandero González, Sergio (Lippincott Williams and Wilkins, 2014)
      Mitochondria are key organelles for ATP production in cardiomyocytes, which is regulated by processes of fission and fusion. We hypothesized that the mitochondria fusion protein dynamin-related protein 1 (Drp1) inhibition, ...
    • Insulin stimulates mitochondrial fusion and function in cardiomyocytes via the AktmTOR-NFkB-Opa-1 signaling pathway 
      Parra, Valentina; Verdejo, Hugo E.; Iglewski, Myriam; Del Campo, Andrea; Troncoso, Rodrigo; Jones, Deborah; Zhu, Yi; Kuzmicic Previtali, Jovan Paolo; Pennanen, Christian; López Crisosto, Camila; Jaña, Fabián; Ferreira, Jorge; Noguera, Eduard; Chiong Lay, Mario; Bernlohr, David A.; Klip, Amira (2014)
      Insulin regulates heart metabolism through the regulation of insulin-stimulated glucose uptake. Studies have indicated that insulin can also regulate mitochondrial function. Relevant to this idea, mitochondrial function ...
    • Mitochondrial dynamics: A potential new therapeutic target for heart failure Dinámica mitocondrial: un ... 
      Kuzmicic, Jovan; Del Campo, Andrea; López Crisosto, Camila; Morales, Pablo E.; Pennanen, Christian; Bravo Sagua, Roberto; Hechenleitner, Jonathan; Zepeda, Ramiro; Castro, Pablo F.; Verdejo, Hugo; Parra, Valentina; Chiong Lay, Mario; Lavandero González, Sergio (2011)
      Mitochondria are dynamic organelles able to vary their morphology between elongated interconnected mitochondrial networks and fragmented disconnected arrays, through events of mitochondrial fusion and fission, respectively. ...
    • Mitochondrial fission is required for cardiomyocyte hypertrophy mediated by a Ca2+-calcineurin signaling pathway 
      Pennanen, Christian; Parra, Valentina; López Crisosto, Camila; Morales, Pablo E.; del Campo, Andrea; Gutierrez, Tomás; Rivera Mejías, Pablo; Kuzmicic, Jovan; Chiong Lay, Mario; Zorzano, Antonio; Rothermel, Beverly A.; Lavandero González, Sergio (Company of Biologists Ltd, 2014)
      Cardiomyocyte hypertrophy has been associated with diminished mitochondrial metabolism. Mitochondria are crucial organelles for the production of ATP, and their morphology and function are regulated by the dynamic processes ...
