      Meeting Abstract
    • Beta(2)-adrenergic receptor regulates cardiac fibroblast autophagy and collagen degradation 
      Aránguiz Urroz, Pablo Daniel; Canales Urriola, Jimena Andrea; Copaja, Miguel; Troncoso Cotal, Rodrigo; Vicencio Bustamante, José Miguel; Carrillo Ballesteros, Constanza Carolina; Lara Peñaloza, Hernán; Lavandero González, Sergio; Díaz Araya, Guillermo (ELSEVIER SCIENCE BV, 2011-01)
      Autophagy is a physiological degradative process key to cell survival during nutrient deprivation, cell differentiation and development. It plays a major role in the turnover of damaged macromolecules and organelles, and ...
    • Effects of Carvedilol upon intra- and interventricular synchrony in patients with chronic heart failure 
      Castro, Pablo; Mac Nab, Paul; Quintana, Juan Pablo; Bittner, Alex; Greig, Douglas; Vergara, I.; Vukasovic Ramírez, José Luis; Corbalán, Ramón; Copaja, Miguel; Díaz Araya, Guillermo; Chiong Lay, Mario; Troncoso Cotal, Rodrigo; Alcaíno Olivares, Hernán Alejandro; Lavandero González, Sergio (EXCERPTA MEDICA INC, 2005-07-15)
      Radionuclide isotopic ventriculography with phase analysis was performed in 30 patients with stable heart failure (HF), determining left ventricular (LV) and interventricular contraction synchrony at baseline and after 6 ...
    • Phospholipase C/protein kinase C pathway mediates angiotensin II-dependent apoptosis in neonatal rat cardiac ... 
      Sánchez Vivar, Raúl; Soto, Cristián; Copaja, Miguel; Mateluna Guajardo, María Francisca; Aránguiz Urroz, Pablo Daniel; Muñoz, Juan Pablo; Chiong Lay, Mario; García Nannig, Lorena; Letelier Vargas, Alan Gonzalo; Thomas, W. G.; Lavandero González, Sergio; Díaz Araya, Guillermo (LIPPINCOTT WILLIAMS & WILKINS, 2008-08)
      Cardiac fibroblasts are the major non-myocyte cell constituent in the myocardium, and they are involved in heart remodeling. Angiotensin II type I receptor (AT(1)R), and changes in its expression have been reported in ...
    • Polimorfismos de los receptores - β Adrenérgicos y su relación con el riesgo de insuficiencia cardíaca, ... 
      Castro Gálvez, Pablo; Greig, Douglas; Copaja, Miguel; Alcaíno Olivares, Hernán Alejandro; Troncoso Cotal, Rodrigo Hernán; Chiong Lay, Mario; Mellado, Rose Marie; Pérez, Osvaldo; Vukasovic Ramírez, José Luis; Díaz Araya, Guillermo; Corbalán, Ramón; Ocaranza, María Paz; Jalil Milad, Jorge; Lavandero González, Sergio (Sociedad Chilena de Cardilología y Cirugía Cardiovascular, 2005)
      Los polimorfismos de los receptores β Adrenérgicos (AR) influencian el grado de actividad del receptor. Los βAR tienen un rol importante en la regulación de la contractilidad y podrían tener implicancias en el riesgo de ...
    • Simvastatin disrupts cytoskeleton and decreases cardiac fibroblast adhesion, migration and viability 
      Copaja, Miguel; Venegas, Daniel; Aranguiz, Pablo; Canales, Jimena; Vivar, Raúl; Avalos, Yennifer; García Nannig, Lorena; Chiong Lay, Mario; Olmedo, Ivonne; Catalán, Mabel; Leyton Campos, Lisette; Lavandero González, Sergio; Díaz Araya, Guillermo (Elsevier, 2012)
      Statins reduce the isoprenoids farnesyl and geranylgeranyl pyrophosphate, essential intermediates, which control a diversity of cellular events such as cytoskeleton integrity, adhesion, migration and viability. Cardiac ...
