    • 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 ...
    • Autophagy in cardiovascular biology 
      Lavandero González, Sergio; Chiong Lay, Mario; Rothermel, Beverly A.; Hill, Joseph A. (American Society for Clinical Investigation, 2015)
      Cardiovascular disease is the leading cause of death worldwide. As such, there is great interest in identifying novel mechanisms that govern the cardiovascular response to disease-related stress. First described in failing ...
    • Down syndrome critical region 1 gene, Rcan1, helps maintain a more fused Mitochondrial Network 
      Parra Ortíz, María Valentina; Altamirano, Francisco; Hernández Fuentes, Carolina; Tong, Dan; Kyrychenko, Victoriia; Rotter, David; Pedrozo Cibils, Zully; Hill, Joseph A.; Eisner, Verónica; Lavandero González, Sergio; Schneider, Jay W.; Rothermel, Beverly A. (Lippincott Williams & Wilkins, 2018)
      Rationale: The regulator of calcineurin 1 (RCAN1) inhibits CN (calcineurin), a Ca2+-activated protein phosphatase important in cardiac remodeling. In humans, RCAN1 is located on chromosome 21 in proximity to the Down ...
    • FoxO1-Dio2 signaling axis governs cardiomyocyte thyroid hormone metabolism and hypertrophic growth 
      Ferdous, Anwarul; Wang, Zhao V.; Luo, Yuxuan; Li, Dan L.; Luo, Xiang; Schiattarella, Gabriele G.; Altamirano, Francisco; May, Herman I.; Battiprolu, Pavan K.; Nguyen, Annie; Rothermel, Beverly A.; Lavandero González, Sergio; Gillette, Thomas G.; Hill, Joseph A. (Nature, 2020)
      Forkhead box O (FoxO) proteins and thyroid hormone (TH) have well established roles in cardiovascular morphogenesis and remodeling. However, specific role(s) of individual FoxO family members in stress-induced growth and ...
    • 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 ...
    • Metabolic stress - Induced activation of FoxO1 triggers diabetic cardiomyopathy in mice 
      Battiprolu, Pavan K.; Hojayev, Berdymammet; Jiang, Nan; Wang, Zhao V.; Luo, Xiang; Iglewski, Myriam; Shelton, John M.; Gerard, Robert D.; Rothermel, Beverly A.; Gillette, Thomas G.; Lavandero González, Sergio; Hill, Joseph A. (2012)
      The leading cause of death in diabetic patients is cardiovascular disease; diabetic cardiomyopathy is typified by alterations in cardiac morphology and function, independent of hypertension or coronary disease. However, ...
    • Mitochondrial fission and autophagy in the normal and diseased heart 
      Iglewski, Myriam; Hill, Joseph A.; Lavandero González, Sergio; Rothermel, Beverly A. (2010)
      Sustained hypertension promotes structural, functional and metabolic remodeling of cardiomyocyte mitochondria. As long-lived, postmitotic cells, cardiomyocytes turn over mitochondria continuously to compensate for changes ...
