    • 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 ...
    • Emerging role of mitophagy in cardiovascular physiology and pathology 
      Morales, Pablo E.; Arias Durán, Carla; Ávalos Guajardo, Yáreni; Aedo, Geraldine; Verdejo, Hugo E.; Parra Ortiz, Valentina; Lavandero González, Sergio (Elsevier, 2020)
      Healthy mitochondrial function is imperative for most tissues, but especially those with a high energy demand. Robust evidence linking mitochondrial dysfunction with cardiovascular disease has demonstrated that mitochondrial ...
    • GLP-1 promotes mitochondrial metabolism in vascular smooth muscle cells by enhancing endoplasmic ... 
      Morales, Pablo E.; Torres, Gloria; Sotomayor Flores, Cristian Alejandro; Peña Oyarzún, Daniel; Rivera Mejías, Pablo; Paredes, Felipe; Chiong Lay, Mario (Academic Press Inc., 2014)
      Incretin GLP-1 has important metabolic effects on several tissues, mainly through the regulation of glucose uptake and usage. One mechanism for increasing cell metabolism is modulating endoplasmic reticulum (ER)-mitochondria ...
    • Is mitochondrial dysfunction a common root of noncommunicable chronic diseases? 
      Díaz Vegas, Alexis; Sánchez Aguilera, Pablo; Krycer, James R; Morales, Pablo E.; Monsalves Álvarez, Matías; Cifuentes Koster, Mariana; Rothermel, Beverly A.; Lavandero González, Sergio (Endocrine Society, 2020)
      Mitochondrial damage is implicated as a major contributing factor for a number of noncommunicable chronic diseases such as cardiovascular diseases, cancer, obesity, and insulin resistance/type 2 diabetes. Here, we discuss ...
    • 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 ...
    • Mitochondrial fragmentation impairs insulin-dependent glucose uptake by modulating Akt activity through ... 
      Del Campo, Andrea; Parra, Valentina; Vásquez Trincado, César Alonso; Gutiérrez, Tomás; Morales, Pablo E.; López Crisosto, Camila; Bravo Sagua, Roberto; Navarro Márquez, Mario F.; Verdejo, Hugo E.; Contreras Ferrat, Ariel Eduardo; Troncoso, Rodrigo; Chiong Lay, Mario; Lavandero González, Sergio (2014)
      Insulin is a major regulator of glucose metabolism, stimulating its mitochondrial oxidation in skeletal muscle cells. Mitochondria are dynamic organelles that can undergo structural remodeling in order to cope with these ...
    • Muscle lipid metabolism: role of lipid droplets and perilipins 
      Morales, Pablo; Bucarey, José Luis; Espinosa Escalona, Alejandra (Hindawi, 2017)
      Skeletal muscle is one of the main regulators of carbohydrate and lipid metabolism in our organism, and therefore, it is highly susceptible to changes in glucose and fatty acid (FA) availability. Skeletal muscle is an ...
