    • Angiotensin-(1–9) prevents cardiomyocyte hypertrophy by controlling mitochondrial dynamics via miR-129-3p/PKIA pathway 

      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 ...
    • Down syndrome and Alzheimer's disease: common molecular traits beyond the amyloid precursor protein 

      Gómez, Wileidy; Morales, Rodrigo; Maracaja Coutinho, Vinicius; Parra Ortiz, Valentina; Nassif, Melissa (Impact Journals LLC, 2020)
      Alzheimer’s disease (AD) is the most prevalent type of dementia. Down syndrome (DS) is the leading genetic risk factor for Early-Onset AD, prematurely presenting the classic pathological features of the brain with AD. ...
    • 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, ...
    • 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 ...
    • Miro1 as a novel regulator of hypertrophy in neonatal rat cardiomyocytes 

      Conejeros, Carolina; Parra Ortiz, Valentina; Sánchez Vergara, Gina; Pedrozo Cibils, Zully; Olmedo Alegría, Ivonne (Elsevier, 2020)
      Cardiac hypertrophy is an adaptive response to manage an excessive cardiac workload and maintain normal cardiac function. However, sustained hypertrophy leads to cardiomyopathy, cardiac failure, and death. Adrenergic ...
    • Sarcoplasmic reticulum and calcium signaling in muscle cells: Homeostasis and disease 

      Bravo Sagua, Roberto; Parra Ortiz, Valentina; Muñoz Córdova, Felipe; Sánchez Aguilera, Pablo; Garrido, Valeria; Contreras Ferrat, Ariel; Chiong Lay, Mario; Lavandero González, Sergio (Elsevier, 2020)
      The sarco/endoplasmic reticulum is an extensive, dynamic and heterogeneous membranous network that fulfills multiple homeostatic functions. Among them, it compartmentalizes, stores and releases calcium within the intracellular ...
