    • Antiproliferative and proapoptotic activities of aza-annulated naphthoquinone analogs 
      Suárez Rozas, Cristian; Simpson, Sebastián; Fuentes Retamal, Sebastián; Catalán, Mabel; Ferreira, Jorge; Theoduloz, Cristina; Mella, Jaime; Cabezas, David; Cassels Niven, Bruce; Yáñez, Claudia; Castro Castillo, Vicente (Elsevier Ltd, 2019)
      © 2018 1,4-Naphthoquinone derivatives have been widely documented with regard to their biological properties, and particularly their anticancer activities. In the 9,10-anthraquinone family, aza-annulation involving one of ...
    • 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 ...
    • Destabilization of mitochondrial functions as a target against breast cancer progression: Role of ... 
      Sandoval Acuña, Cristian; Fuentes Retamal, Sebastián; Guzmán Rivera, Daniela; Peredo Silva, Liliana; Madrid Rojas, Matías; Rebolledo, Solange; Castro Castillo, Vicente; Pavani, Mario; Catalán, Mabel; Maya Arango, Juan; Jara, Jose A.; Parra, Eduardo; Calaf, Gloria M.; Speisky Cosoy, Hernán; Ferreira Parker, Jorge (2016)
      Mitochondrion is an accepted molecular target in cancer treatment since it exhibits a higher transmembrane potential in cancer cells, making it susceptible to be targeted by lipophilic-delocalized cations of triphenylphosphonium ...
    • 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 ...
    • Electrochemistry of interaction of 2-(2-nitrophenyl)-benzimidazole derivatives with DNA 
      Catalán, Mabel; Álvarez Lueje, Alejandro; Bollo Dragnic, Soledad (2010)
      In this study the interaction between new benzimidazole molecules, 2-(2-nitrophenyl)-1H-benzimidazole (NB) and N-benzoyl-2-(2-nitrophenyl)-benzimidazole (BNB), with dsDNA and ssDNA was assessed at pH 7.4. Using differential ...
    • Simvastatin induces apoptosis by a Rho-dependent mechanism in cultured cardiac fibroblasts and myofibroblasts 
      Copaja, Miguel; Venegas, Daniel; Aránguiz, Pablo; Canales, Jimena; Vivar, Raúl; Catalán, Mabel; Olmedo, Ivonne; Rodríguez, Andrea E.; Chiong Lay, Mario; Leyton Campos, Lisette; Lavandero González, Sergio; Díaz Araya, Guillermo (2011)
      Several clinical trials have shown the beneficial effects of statins in the prevention of coronary heart disease. Additionally, statins promote apoptosis in vascular smooth muscle cells, in renal tubular epithelial cells ...
    • 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; ...
