    • Hypoxia stimulates via separate pathways ERK phosphorylation and NF-κB activation in skeletal muscle cells ... 
      Osorio Fuentealba, César; Valdés, Juan Antonio; Riquelme, Denise; Segura Hidalgo, Jorge Antonio; Hidalgo Tapia, María Cecilia; Carrasco, María Angélica (2009)
      Mammalian cells sense oxygen levels and respond to hypoxic conditions through the regulation of multiple signaling pathways and transcription factors. Here, we investigated the effects of hypoxia on the activity of two ...
    • IGF-1 Induces IP3-Dependent Calcium Signal Involved in the Regulation of Myostatin Gene Expression Mediated ... 
      Valdés, Juan A.; Flores, Sylvia; Fuentes, Eduardo N.; Osorio Fuentealba, César; Jaimovich Pérez, Enrique; Molina, Alfredo (Wiley Periodicals, 2013)
      Skeletal muscle differentiation is a complex and highly regulated process characterized by cell cycle arrest, which is associated with morphological changes including myoblast alignment, elongation, and fusion into ...
    • Insulin elicits a ROS-activated and an IP3-dependent Ca2+ release, which both impinge on GLUT4 translocation 
      Contreras Ferrat, Ariel Eduardo; Llanos Vidal, Paola; Vásquez, César; Espinosa, Alejandra; Osorio Fuentealba, César; Arias Calderón, Manuel; Lavandero González, Sergio; Klip, Amira; Hidalgo Tapia, María Cecilia; Jaimovich Pérez, Enrique (The Company of Biologists Ltd, 2014)
      Insulin signaling includes generation of low levels of H2O2; however, its origin and contribution to insulin-stimulated glucose transport are unknown. We tested the impact of H2O2 on insulin-dependent glucose transport ...
    • Insulin-Dependent H2O2 Production Is Higher in Muscle Fibers of Mice Fed with a High-Fat Diet 
      Espinosa, Alejandra; Campos, Cristian; Díaz Vegas, Alexis; Galgani Fuentes, José; Juretic Díaz, Nevenka Militza; Osorio Fuentealba, César; Bucarey, José L.; Tapia, Gladys; Valenzuela, Rodrigo; Contreras Ferrat, Ariel Eduardo; Llanos Vidal, Paola; Jaimovich Pérez, Enrique (2013)
      Insulin resistance is defined as a reduced ability of insulin to stimulate glucose utilization. C57BL/6 mice fed with a high-fat diet (HFD) are a model of insulin resistance. In skeletal muscle, hydrogen peroxide (H2O2) ...
