    • Angiotensin-(1-9) reverses experimental hypertension and cardiovascular damage by inhibition of the angiotensin ... 
      Ocaranza, Maria Paz; Moya, Jackeline; Barrientos, Victor; Alzamora, Rodrigo; Hevia, Daniel; Morales, Cristobal; Pinto, Melissa; Escudero, Nicolás; García Nannig, Lorena; Novoa, Ulises; Ayala, Pedro; Díaz Araya, Guillermo; Godoy, Ivan; Chiong Lay, Mario; Lavandero González, Sergio; Jalil Milad, Jorge (Lippincott Williams and Wilkins, 2014)
      BACKGROUND:: Little is known about the biological effects of angiotensin-(1-9), but available evidence shows that angiotensin-(1-9) has beneficial effects in preventing/ameliorating cardiovascular remodeling. OBJECTIVE:: ...
    • Attenuation of endoplasmic reticulum stress using the chemical chaperone 4-phenylbutyric acid prevents ... 
      Ayala, Pedro; Montenegro, José; Vivar, Raúl; Letelier, Alan; Urroz, Pablo Aránguiz; Copaja, Miguel; Pivet, Deisy; Humeres, Claudio; Troncoso, Rodrigo; Vicencio, José Miguel; Lavandero González, Sergio; Díaz Araya, Guillermo (2012)
      Increasing evidence indicates that endoplasmic reticulum (ER) stress is involved in various diseases. In the human heart, ischemia/reperfusion has been correlated to ER stress, and several markers of the unfolded protein ...
    • Cardiac fibroblast death by ischemia/reperfusion is partially inhibited by IGF-1 through both PI3K/Akt and ... 
      Vivar, Raúl; Humeres, Claudio; Varela, Marcelo; Ayala, Pedro; Guzmán, Nancy; Olmedo, Ivonne; Catalán, Mabel; Boza Fuentes, Pía; Muñoz, Claudia; Díaz Araya, Guillermo (2012)
      Cardiac fibroblast (CF) death by ischemia/reperfusion (I/R) has major implications for cardiac wound healing. Although IGF-1 has well-known cytoprotective effects, no study has been done on CF subjected to simulated ...
    • Differential regulation of collagen secretion by kinin receptors in cardiac fibroblast and myofibroblast 
      Catalán, Mabel; Smolic, Christian; Contreras, Ariel; Ayala, Pedro; Olmedo, Ivonne; Copaja, Miguel; Boza Fuentes, Pía; Vivar, Raúl; Avalos, Yennifer; Lavandero González, Sergio; Velarde, Victoria; Díaz Araya, Guillermo (2012)
      Kinins mediate their cellular effects through B1 (B1R) and B2 (B2R) receptors, and the activation of B2R reduces collagen synthesis in cardiac fibroblasts (CF). However, the question of whether B1R and/or B2R have a role ...
    • EPAC expression and function in cardiac fibroblasts and myofibroblasts 
      Olmedo, Ivonne; Muñoz, Claudia; Guzmán, Nancy; Catalán, Mabel; Vivar, Raúl; Ayala, Pedro; Humeres Martínez, Claudio; Aránguiz, Pablo; García Nannig, Lorena; Velarde, Victoria; Díaz Araya, Guillermo (Elsevier, 2013)
      In the heart, cardiac fibroblasts (CF) and cardiac myofibroblasts (CMF) are the main cells responsible for wound healing after cardiac insult. Exchange protein activated by cAMP (EPAC) is a downstream effector of cAMP, ...
    • TGF-β1 prevents simulated ischemia/reperfusion-induced cardiac fibroblast apoptosis by activation of both ... 
      Vivar, Raúl; Humeres, Claudio; Ayala, Pedro; Olmedo, Ivonne; Catalán, Mabel; García Nannig, Lorena; Lavandero González, Sergio; Díaz Araya, Guillermo (2013)
      Ischemia/reperfusion injury is a major cause of myocardial death. In the heart, cardiac fibroblasts play a critical role in healing post myocardial infarction. TGF-β1 has shown cardioprotective effects in cardiac damage; ...
    • Toll-like receptor 4 activation prevents rat cardiac fibroblast death induced by simulated ischemia/reperfusion 
      Parra Flores, Pablo Ignacio; Espitia Corredor, Jenaro Antonio; Espinoza Pérez, Claudio Andrés; Queirolo, Cristian; Ayala, Pedro; Brüggendieck, Francisca; Salas Hernández, Aimee; Pardo Jiménez, Viviana Gladys; Díaz Araya, Guillermo Antonio (Frontiers Media, 2021)
      Death of cardiac fibroblasts (CFs) by ischemia/reperfusion (I/R) has major implications for cardiac wound healing. In in vivo models of myocardial infarction, toll-like receptor 4 (TLR4) activation has been reported as ...
