    • Parallel activation of Ca2+-induced survival and death pathways in cardiomyocytes by sorbitol-induced ... 
      Chiong Lay, Mario; Parra, V.; Eisner, V.; Ibarra, C.; Maldonado, C.; Criollo Céspedes, Alfredo; Bravo, R.; Quiroga, C.; Contreras, A.; Vicencio Bustamante, José; Cea, P.; Bucarey, J.; Molgó, Jordi; Jaimovich Pérez, Enrique; Hidalgo Tapia, María Cecilia; Kroemer, G.; Lavandero González, Sergio (2010)
      Hyperosmotic stress promotes rapid and pronounced apoptosis in cultured cardiomyocytes. Here, we investigated if Ca2+ signals contribute to this response. Exposure of cardiomyocytes to sorbitol [600 mosmol (kg water)(-1)] ...
    • Phosphorylation of phosphatidylinositol by transverse tubule vesicles and its possible role in excitation ... 
      Hidalgo Tapia, María Cecilia; Carrasco, María Angélica; Magendzo, Karin; Jaimovich Pérez, Enrique (1986)
      Phosphorylation of phosphatidylinositol to phosphatidylinositol 4-monophosphate and to phosphatidyl-inositol 4,5-bisphosphate was demonstrated in transverse-tubule membranes isolated from frog skeletal muscle using [γ-32P]ATP ...
    • Skeletal muscle excitation-metabolism coupling 
      Díaz Vegas, Alexis; Eisner, Verónica; Jaimovich Pérez, Enrique (Academic Press Inc., 2019)
      Mitochondria represent the main source of ATP in skeletal muscle and mitochondria activity increases after muscle fiber depolarization. The regulation of mitochondrial function during contraction in skeletal muscle, however, ...
    • The cholesterol-lowering agent methyl-β-cyclodextrin promotes glucose uptake via GLUT4 in adult muscle ... 
      Llanos Vidal, Paola; Contreras Ferrat, Ariel; Georgiev, Tihomir; Osorio Fuentealba, César; Espinosa, Alejandra; Hidalgo, Jorge; Hidalgo Tapia, María Cecilia; Jaimovich Pérez, Enrique (American Physiological Society, 2015)
      Insulin stimulates glucose uptake in adult skeletal muscle by promoting the translocation of GLUT4 glucose transporters to the transverse tubule (T-tubule) membranes, which have particularly high cholesterol levels. We ...
    • Transverse tubules from frog skeletal muscle. Purification and properties of vesicles sealed with the ... 
      Hidalgo Tapia, María Cecilia; Lecocq Parra, Claudio; Riquelme, Gloria; Jaimovich Pérez, Enrique (1986)
      Transverse tubule vesicles were isolated from frog skeletal muscle by a procedure initially described by Rosemblatt (J. Biol. Chem. 256, 8140-8148 (1981)) and later modified by Hidalgo (J. Biol. Chem. 258, 13937-13945 ...
